Chronology
Predecessor	Chevrolet K5 Blazer/GMC K5 Jimmy

The Chevrolet Tahoe, and its badge-engineered GMC Yukon counterpart, are full-size SUVs and other trucks from General Motors, offered since 1994 and 1991, respectively. Since 1982, Chevrolet and GMC sold two different-sized SUVs under their "Blazer" and "Jimmy" nameplates, by introducing the smaller S-10 Blazer and GMC S-15 Jimmy for the 1983 model year, below the full-size Blazer and Jimmy models. This situation lasted into the early 1990s. GMC first rebadged the full-size Jimmy as the "Yukon" in 1991. Chevrolet however waited until 1994, when they rebadged the redesigned mid-size S-10 Blazer the "new Blazer," while renaming the full-size Blazer as the "Tahoe." The name Tahoe refers to the rugged and scenic area surrounding Lake Tahoe in the western United States, and was originally used as a trim level on S-10 models. The name Yukon refers to the Yukon territory of northern Canada.

For the 1995 model year, the Tahoe and Yukon gained a new, longer four-door model, slotting in size between the two-door models and the longer-wheelbase Chevrolet Suburban/GMC Yukon XL.

The Tahoe is sold in North America, parts of Asia such as the Philippines, and the Middle East, plus other countries including Bolivia, Chile, Peru, Colombia, Ecuador, and Angola as a left-hand-drive vehicle. The Yukon is only sold in North America and the Middle East.

The Chevrolet Tahoe and GMC Yukon are part of General Motors' full-size SUV family and are differentiated from the similar Chevrolet Suburban and GMC Yukon XL primarily by the length of the passenger and cargo area behind the C-pillar. An upscale trim GMC Denali sub-model joined the Yukon lineup as the top-of-the-line trim for the 1999 model year; the Cadillac Escalade is a closely related upscale version sharing the same platform. The Denali is available on both standard and XL versions.

The Tahoe has regularly been the best-selling full-size SUV in the United States, frequently outselling its competition by two to one.

1994 GMC Yukon GT

1995 Chevrolet Tahoe LT 4-door

1997 Chevrolet Tahoe base 2-door, with unique grille and sealed-beam headlights

The new GMC Yukon was introduced in 1991 for the 1992 model year, succeeding the 2nd generation (K5) Jimmy, while Chevrolet continued to use the Blazer name on its third-generation K5 model, through the 1994 model year. Removable hard-tops were dropped. All models now had a full-length steel roof, and were 2-door wagons only, through 1994.

However, for 1995, the "Blazer" nameplate was discontinued (now used only on the mid-size GMT325 Blazer), and the model was rebranded as the all-new Chevrolet Tahoe, while also adding all-new, longer 4-door versions, for both brands. Four-door Yukon and Tahoe production started on January 20, 1995, at Janesville Assembly. The Tahoe was Motor Trend magazine's Truck of the Year for 1996.

The Tahoe and Yukon are considerably shorter than the Suburban on which they are based, but share that vehicle's GMT400 platform. It is built on a true truck chassis, derived from the one in the C/K 1500 full-size pickup truck. Both two-door and four-door models were produced in rear- and four-wheel drive versions. Four-door models had a 6 in (15 cm) longer wheelbase, and 11 in (28 cm) greater length than the two-door models. Two-door models weighed roughly 4,500 lb (2,041 kg) while four-door models weighed about 5,500 lb (2,495 kg). Tahoes were available in base, LS, and LT trim levels, and the Yukon in base, SLE, and SLT. A "Yukon GT" trim level on 1992–1994 2-door Yukons was also available, featuring monochromatic grille, front and rear bumpers, "Yukon GT" badges on both doors, and bucket seating with center console. "AutoTrac" full-time all-wheel drive and a programmable Homelink garage door transmitter were added for 1998. The upscale Denali trim line for the Yukon was introduced in 1999.

The standard engine was Chevrolet's 350 cu in (5.7 L) small-block V8, while a turbocharged 6.5 L (395 cu in) Detroit Diesel V8 was available beginning in 1994. The 6.5-liter turbo diesel was only available in two-door 4WD models and was detuned to 360 lb⋅ft (488 N⋅m) torque considering the Tahoe's rear axle capacity.

In Mexico, the two-door Tahoe was released in 1995, called the Chevrolet Silverado, and in 1998, the four-door model was released as the Silverado 4-door. Both models were available with the Base, LS, or luxury LT trim packages. In Venezuela, the two-door Tahoe was released in 1993 (4WD only), called the Chevrolet Grand Blazer, and in 1996, the four-door model was released as the Grand Blazer 4-door (2WD). In 1996, the 2-door was discontinued and only the Grand Blazer 4-door 4WD was available. In Bolivia, the four-door model was released in 1995 as the Tahoe 4-door (4WD).

Beginning in 1994, GM began making numerous annual changes to the Blazer/Yukon, including:

• Revised front clip – Blazer and Yukon (1994)
• Revised interior including a driver-side air bag and other new features, revised side mirrors, Blazer renamed Tahoe, four-door option included (1995)
• Revised Vortec 5700 (350 cu in) engine with increased power and fuel efficiency, 2-door models now available with 2WD, electronic 4WD shifting, daytime running lights, and illuminated entry (1996)
• Revised front clip – Mexican-market Silverado (1996)
• Revised automatic transmission, new EVO (electronic variable orifice) speed-sensitive power steering system and added passenger-side airbag, last year of the two-door Yukon (1997)
• Programmable Homelink garage door transmitter, PassLock security system, heated front seats optional, air conditioning for rear seat passengers, AutoTrac automatic 4WD option added, second-generation airbags, transmissions revised again (1998)
• Last year of the two-door Tahoe (1999)

Tahoe Limited and Tahoe Z71

2000 Chevrolet Tahoe Limited

When the GMT800-based Chevrolet Tahoe/GMC Yukon was released for the 2000 model year, a 2WD Tahoe Limited and 4WD Tahoe Z71 remained in production on the GMT400 platform as special edition vehicles. These vehicles were produced in the Arlington, Texas, assembly plant for the 2000 model year only.

The Chevrolet Tahoe Limited was based on the Chevrolet Tahoe SS concept vehicle introduced in 1996 that never made it to production. It is reported that GM disliked the idea of an SS-badged vehicle at a time when insurance companies were already demanding higher premiums for SUVs. The Tahoe SS prototype vehicles made in 1996 were painted either an unspecified metallic green or metallic blue, but the Tahoe Limited was produced only in Onyx Black. The Tahoe Limited had a distinctive exterior appearance that included a factory equipped ground effects package, a monochromatic theme with bumpers and grille painted in the same high gloss black as the body, removal of the roof rack, and fog lamps integrated into the front bumper. Other notable features of the Tahoe Limited included the Z60 high-performance chassis package (commonly known as the police package) which places the body of the vehicle 2 in (51 mm) lower than the 4WD Tahoe, two-tone gray and charcoal leather interior seating surfaces, a 120 mph (190 km/h) gauge cluster, 46 mm (1.8 in) Bilstein shock absorbers, a 3.42:1 or optional 3.73:1 rear axle ratio, a limited slip rear differential, an engine oil cooling system, and distinctive 16-inch Ronal R36 five-spoke aluminum wheels wearing 255/70R16 tires.

2000 Chevrolet Tahoe Z-71 Special Edition

The Chevrolet Tahoe Z71 also exhibited a monochromatic appearance similar to the Tahoe Limited, but instead of Onyx Black, the Tahoe Z71 was offered in either Light Pewter Metallic, Victory Red, Emerald Green Metallic, or Indigo Blue Metallic. Features of the Tahoe Z71 were similar to those of the Tahoe Limited with a few key differences to distinguish the 2WD Tahoe Limited from the 4WD Tahoe Z71. Features that differ from those previously mentioned on the Tahoe Limited included the Z71 off-road chassis package (46 mm (1.8 in) Bilstein shock absorbers, a standard 3.73:1 rear axle ratio for the G80 locking differential), color-keyed wheel flares, trim, grille, and bumpers, underbody skid plates, inset driving lights built into the center of the front bumper, oversized two-row radiator, two-tone leather seating surfaces in either a gray or neutral theme, distinctive taillamp lens protectors, black tubular side assist step bars, black brush guard, and distinctive 16-inch Alcoa five-spoke six-lug polished aluminum wheels.

The L31 5.7L Vortec V8 powerplant and 4L60E four-speed automatic transmission shared with other GMT400 Chevrolet Tahoe vehicles were not modified in these special edition vehicles, and as such, these special editions were mostly appearance packages, albeit with unique-handling suspension options.

GMC Yukon Denali

GMT400 GMC Yukon Denali

In 1998, at the time of its introduction, the Yukon Denali was GM's answer to the Lincoln Navigator. GM, however, soon introduced the Escalade – a Yukon Denali clone under the Cadillac nameplate, which competed directly with the Lincoln. The Yukon Denali's exterior was shared with the Escalade, with the entire front clip and lower side body panels differing from those of the standard Yukon. In the interior, the Denali featured luxury options not available in the Yukon. These included an upgraded leather interior, power seats, heated front and rear seats, Bose stereo system, and woodgrain trim on the dashboard. The 1999 Yukon Denali and Escalade also saw the first application of GM's OnStar communications system in a full-size SUV. This generation Yukon Denali (and the Escalade) was kept on the GMT400 platform for the 2000 model year, while the remainder of the lineup was changed to the new GMT800.

Chevrolet Tahoe rear view

Front view and interior of second-generation GMC Yukon

Other than the Tahoe Limited and Z71, the vehicle was redesigned and launched in January 2000 for the 2000 model year on the new GMT800 platform, still shared with the full-sized pickups and SUVs. Two new engines replaced the 5.7L (350 cu in) Chevrolet small-block V8, and while both were smaller, both produced more horsepower but less torque. In Mexico, the GMT800 Chevrolet Tahoe is called the Chevrolet Sonora. A 2-door GMT800 Tahoe prototype was made but never entered production. Suburban and Tahoe models sold in Mexico still offered the 5.7L small-block Chevrolet V8 (RPO code R31) as an option in early models, whereas it was replaced by the new 5.3L Vortec V8 engine (or the 4.8L Vortec V8 in base Tahoe models) in all other markets.

Both vehicles received significant updates with only the grille, headlights and body-side moldings distinguishing one from the other. Both vehicles now featured softer lines as part of a more aerodynamic design. The interior was also updated with new seats, dashboard, and door panels.

GMC Yukon Denali

2006 GMC Yukon Denali

Even though the Yukon was redesigned alongside the Chevrolet Suburban and Tahoe in 2000, the Denali and Escalade remained on the GMT400 platform. It was not until 2001 that the Denali and Escalade were redesigned. While the Escalade departed from its Yukon-based exterior design scheme in attempt to hide its roots, the Yukon Denali's exterior is almost the same as that of a post-2000 model year GMT800 Yukon. A larger 6.0L engine, embossed side body panels, slightly reworked headlights with projector-beam lenses and reworked turn signal indicators, exclusive six-spoke 17-inch polished aluminum wheels with "GMC" embossed center caps, unique chrome "punch" grille, monochromatic front bumper with unique rounded fog lamps, monochromatic rear bumper, "DENALI" lettering on both front doors, exclusive two-tone leather seating surfaces with heated second row seats, a Driver Information Center module located in the center console, premium Bose Lux sound system with optional rear DVD entertainment system, and "YUKON DENALI" stitching on interior door surfaces and front headrests differentiate the Yukon Denali from the regular Yukon. 2001 also saw the introduction of the aforementioned "punch" grille, which has since become a hallmark of the Denali submodel. The Yukon Denali of this generation is powered by the 6.0L Vortec 6000 V8, which was also found in the 2001 GMC Sierra C3 Denali. The Yukon Denali received a minor interior refresh for the 2003 model year. This refresh updated the gauge cluster, center console/armrest, and steering wheel. Ths redesign relocated the revised Driver Information Center/odometer to the bottom of the gauge cluster, and was now operated by buttons along the bottom of the newly revised steering wheel (the top portion of the wheel held newly revised audio controls). A storage cubby was placed in lieu of the 2001–2002 Driver Information Center module, and the armrest was no longer a locking armrest. This refresh also saw the removal of the "Yukon Denali" interior embossments that were previously used on the 2001–2002 Denali's interior panels and headrests. The second row seating arrangements were now standard heated captain's chairs instead of the previous second row bench seat. A premium Bose DVD-based navigation system and Bose subwoofer were also added as available options for 2003.

2003 Tahoes provided early compliance to the 2005 LATCH (Lower Anchors and Tethers for Children) federal safety standards. A redesigned instrument cluster featured a new Driver Information Center, which can monitor and report on up to 34 different vehicle system functions such as Service StabiliTrak, Ice Possible, and Door Ajar. The interior was refreshed, including a new eight-button steering wheel that allows the driver to safely access new infotainment features as well as a redesigned center console.

There were also new improvements to the powertrain and electrical system for 2003. These included a new Electronic Throttle Control (ETC) system to improve throttle feel and new oxygen sensors to improve durability and reduce emissions during engine warm-up. Models sold in California received a more robust catalytic converter to meet Ultra Low Emissions Vehicle (ULEV) standards. A new battery-rundown protection system automatically turns off the headlamps, parking lamps, and interior lighting if left on for more than 10 minutes with the key removed from the ignition.

New colors for 2003 include Sandalwood Metallic and Dark Spiral Gray Metallic.

2004

The Tahoe received minor updates for 2004, most notably newly designed 16 and 17-inch wheel choices and a tire pressure monitoring system. Hydroboost brakes and a front passenger seat belt reminder were also added as was a 7-pin to 4-pin trailer brake wiring adapter. 2004 was the final year the Tahoe could be ordered with rear barn doors.

New colors include Sandstone Metallic and Bermuda Blue Metallic.

2006

2006 marked the final year of the Tahoe and Yukon on the GMT800 platform, and because of this, only minor changes were made. These changes included StabiliTrak becoming standard on all models, combining the OnStar and XM Satellite Radio antennas into one single unit, removal of the Chevrolet badging on the liftgate, removal of rubber trim from the liftglass, relocating the catalytic converter closer to the engine to improve emissions performance, and a new manual parking brake adjuster.

2010–2014 GMC Yukon SLT

2007 Chevrolet Tahoe LT

General Motors redesigned the Tahoe and Yukon on the new GMT900 platform for the 2007 model year. A hybrid version of the Tahoe/Yukon, which uses the shared GM/Chrysler Advanced Hybrid System 2, followed with the 2008 models. The GMT900-based Tahoe and Yukon exceeded initial sales expectations and continued to sell well despite a weakening market for large SUVs. The short-wheelbase Tahoe and its police counterpart began production at Arlington Assembly on December 1, 2005. SWB Yukon production began in early 2006, with Janesville Assembly coming online as well. For the first time, GM used the Tahoe name in Mexico.

For 2007, the GMC Yukon and Chevrolet Tahoe received different front fascias, hood, and tail lights. The GMC Yukon boasted a monolithic grille and headlights, while the Chevrolet Tahoe grille was divided by a body-colored bar similar to the chrome bar found on the GMT800 Tahoe. Both the redesigned Yukon and Tahoe featured a more crisp, upright, angular design that gave the vehicles a prominent, more upscale appearance than that of their predecessors. The interior was significantly redesigned as well, with features such as a faux wood trim dashboard with chrome-accented instrument controls and new inset gauge cluster design. New door panels, as well as new seats, were also added to the interior. The interior still retains its nine-passenger seating availability, but only on the base Tahoe 1LS/Yukon SLE models, like the Suburban and Yukon XL counterparts. The Tahoe/Suburban 1LS would now become the base model for 2007, adding the premium LTZ trim level as the upper Tahoe/Suburban equipment level. The Yukon/Yukon XL would retain its SLE/SLT/Denali trims.

Highway mileage was improved from 19 mpg_‑US (12 L/100 km; 23 mpg_‑imp) to 21 to 22 mpg_‑US (11 to 11 L/100 km; 25 to 26 mpg_‑imp) with the addition of Active Fuel Management cylinder deactivation. For 2009, the 6.2 L engine in the Yukon Denali got a power increase to 403 hp (301 kW), while a 395 hp (295 kW) 6.2L was added as an option for the Tahoe LTZ. A 6-speed 6L80 automatic transmission replaced the 4-speed on all trucks except 2WD models with the 4.8L engine. The 2011 model has a NHTSA rollover risk of 24.6%, and a lateral roadholding of 0.79g.

In 2008, a two-mode hybrid was offered with two trim levels, HY1 or HY2. A 332 hp (248 kW) 6.0L Vortec 6000 with a pair of 80-hp/ 184 ft.-lb. torque electric motors was offered. It had a 0.34–0.36 drag coefficient from upgraded body panels and a 12V/300V battery system. The hybrid models also included 300V Electric AC, 42V power steering, and LED taillights (only an option from 2008 to 2013). This variant was named the Green Car of the Year for 2008 by Green Car Journal, a decision which was later lampooned during a segment of the BBC series Top Gear.

During the 2009 model year, LTZ models had the option of the 405 hp (302 kW) 6.2L Vortec 6200. The option was dropped after only one model year.

2010 models underwent a mild mid-cycle refresh including a slightly raised bumper, removal of the GM "Mark of Excellence" door badge, revised interior door trim, improved side structure, side torso airbags and optional side blind zone alert.

For 2012, the GMC Yukon offered a special Heritage Edition package, featuring unique Heritage Edition exterior badging, embroidered color-keyed carpeted floor mats, embroidered headrests, SLT-2 Equipment Group standard features (such as 10-way memory leather seats and power liftgate), and optional 20-inch wheels. The Heritage Edition added $1,970 to the price of the Yukon and Yukon XL and was offered in three colors, Heritage Blue, White Diamond Tricoat, and Onyx Black.

GMC Yukon Denali

2011 GMC Yukon Denali

The Yukon Denali was redesigned for the 2007 model year alongside the regular mainstream Yukon. The biggest change was in the styling, such as the flattened tailgate reminiscent of the new Tahoe, and particularly the grill and headlight shapes, which made the Yukon look less aggressive than previous models. The only exterior difference between the Yukon Denali and the standard Yukon are the chrome grille and extensive use of chrome accents and the Escalade rear bumper; and of course the insignias, embeveled rocker panels, chromed headlights, and the Vortec 6200 engine, which it shares with the Cadillac Escalade. For the 2009 model year, the Yukon came fitted with a standard power-tilting steering wheel, exclusive to the Denali trim.

The Apprentice make-your-own-ad contest

In 2006, the 2007 Tahoe was featured on and promoted through Donald Trump's TV series, The Apprentice, where the two teams put together a show for the top General Motors employees to learn about the new Tahoe. Also, The Apprentice sponsored a controversial online contest in which anyone could create a 30-second commercial for the new Tahoe by entering text captions into the provided video clips; the winner's ad would air on national television. An early example of user-generated marketing, headed by ad agency Campbell Ewald, the campaign began to backfire when hundreds of environmentally conscious parodies flooded YouTube and Chevy's website critiquing the vehicle for its low gas mileage. Over 400 negative ads were created in total; however, over 20,000 positive ads were created which Chevrolet viewed as successful in spite of the negative media attention.

GMC Yukon SLT

The Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, GMC Yukon XL, Cadillac Escalade, and Cadillac Escalade ESV had a shortened 2014 model year starting in June 2013, and was replaced with a new version in February 2014 as a 2015 model.

The Tahoe and Yukon were built on the GMT K2XX platform and assigned as K2UC (for Chevrolet Tahoe) and K2UG (for GMC Yukon). Production on the Tahoe and Yukon began in December 2013 with the first completed SUVs being used for testing purposes, and started officially shipping the vehicles to dealerships on February 5, 2014. The 2015 Tahoe was later named the fastest-selling vehicle for February 2014, averaging seven days of sales upon its release. On September 12, 2013, GM released photos and press release of the fourth-generation Tahoe and Yukon. Like its larger siblings Suburban and Yukon XL, the front fascias of the Tahoe and Yukon are distinct, but from the base of the A-pillars back, they share most of the same styling cues. This now includes inlaid doors that tuck into the door sills, instead of over them, improving aerodynamics and fuel economy, and lessens interior noise. The hoods and liftgate panels now are made of aluminum in an effort to reduce vehicle weight. A more-efficient, direct-injected EcoTec3 powertrain coupled with improved aerodynamics help increase fuel economy for the SUVs. Both fourth-generation SUVs do not share a single piece of sheet metal or lighting element with the brands' full-size pickup trucks, and the front grilles of both vehicles are slightly altered to give them their own identity. The front headlights feature projector-beam headlamps flanking the Chevrolet-signature dual-port grille – chrome on all models, sweeping into the front fenders, while the LTZ trims feature high-intensity discharge headlamps and LED daytime running lamps.

Also new were the addition of fold-flat second- and third-row seats, now a standard feature but could be equipped with an optional power-folding feature for the upgraded trims, and an additional two inches of leg room for second-row passengers. The Tahoe now had an available power-tilt, telescoping steering wheel. For the Yukon variant, this feature was carried over from 2009–2014 Yukon Denali, now available in the SLT trim as well. The third-row fold-flat feature was accomplished using a raised platform that reduces available cargo space behind the third-row seats. Standard third-row seats and raised "fold-flat" platform significantly reduced available cargo space compared with previous Tahoe models. Multiple USB ports and power outlets were now spread throughout their interiors, including one 110-volt, three-prong outlet, with the Tahoe adding an available eight-inch color touch-screen radio with next-generation MyLink connectivity along with an available rear-seat entertainment system (but did not feature a Blu-ray option which was exclusive to the Suburban for 2015), while the Yukon added a standard eight-inch-diagonal color touch screen radio with enhanced IntelliLink and available navigation.

The Yukon interior had more features including seats stuffed with dual-firmness foam, a standard Bose sound system and SD card slots, and laminated glass for the windshield and front windows, decreasing interior noise. GM's third-generation magnetic ride control suspension is optional on the Tahoe LTZ models, whose upgraded features included third-generation magnetic ride control, a real-time damping system that delivers more precise body motion control by "reading" the road every millisecond, and changing damping in just five milliseconds.

The new platform was based on the 2014 Chevrolet Silverado/GMC Sierra 1500. Both SUVs featured sound-deadening material to improve cabin quietness. A new Cadillac Escalade and Cadillac Escalade ESV arrived in dealerships in April 2014. Models continued for the Tahoe and Suburban as LS, LT, and LTZ, and the Yukon and Yukon XL as SLE, SLT, and Denali. The Tahoe and Yukon went on sale in February 2014 as an early 2015 model year vehicle. Prices for the all-new GM SUVs were similar to the previous-generation GMT900 SUVs. The Hybrid models were all dropped along with their powertrains, and the Yukon Denali AWD was also dropped as well.

On September 26, 2014, Chevrolet debuted the updated Z71 Tahoe at the State Fair of Texas, along with the debut of the Texas Edition Tahoe, the latter because of Texas having the largest units of Tahoes sold in the United States (as of August 2014, sales of the Chevrolet SUVs in Texas were up 37 percent) and to celebrate the 60th anniversary of GM's Arlington Assembly plant; production began in October 2014. As with the previous Z71 Tahoe, this version continued to be offered in a 4WD LT trim only, featuring a front skid plate, off-road tires mounted on 18-inch wheels, a unique grille, running boards, and "Z71" identification inside and out. Fog lamps, front tow hooks, and front parking assist were also included. The Texas Edition was available in both LT and LTZ trims, featuring a maximum trailering package, twenty-inch polished aluminum wheels (on LT models), 22-inch premium painted aluminum wheels (on LTZ models), and an exclusive "Texas Edition" badge. The Texas Edition Tahoe package was part of a lineup that also used the Texas Edition package, alongside the Suburban and Silverado.

The demand and interest in the redesigned Tahoe also translated into a 108 percent sales spike since it went on sale in February 2014, with most dealers reporting the units being sold within 17 days after they arrive on the dealership lots, with most customers opting for the fully-optioned LTZ model, making it one of Chevrolet's fastest-selling vehicles in 2014 along with the Suburban, which posted even quicker inventory turnovers.

GMC Yukon Denali

2020 GMC Yukon XL Denali

The Yukon Denali was redesigned and updated along with other GM SUVs in September 2013 and went to dealerships on February 5, 2014 as a 2015 model. The Yukon Denali continued with the top-of-the-line features (using similar features as found on the Tahoe LTZ trim) and the front grille honeycomb design. It was now also equipped with a new active noise-cancellation technology and GM's third-generation magnetic ride control suspension as a standard feature. For the first several years, the 6.2-liter V8 was unique to the Denali (and Russian-market Tahoes), but in 2018, this was also made available on the Tahoe LTZ. In November 2014, the Yukon Denali saw its MSRP bumped up by $1,300, partly as a result of the loaded features added to its 2015 mid-year updates. For the 2018 model year, the Yukon Denali received a ten-speed automatic transmission in place of the 8-speed units used on other models.

Safety recalls

On March 23, 2014, a 2015 GMC Yukon caught fire and went up in flames in Anaheim, California, after a couple, who along with the sales representative who was giving them a test drive, noticed the vehicle stopping and that smoke was starting to make its way into the cabin, prompting the three individuals to park the car and escape before it was destroyed within 15 minutes. The cause of the fire was traced to an oil leak and an engine malfunction. Despite being an isolated incident, the 2015 Tahoe and Yukon were not believed to be tied to GM's announced recall of its vehicles that was made on March 17, 2014. But five days later on March 28, 2014, GM announced a recall on the 2015 Tahoe and Yukon in order to fix a "transmission oil cooler line that is not securely seated in its fitting," causing the vehicle to stop and rupture the oil cooling line, resulting in the engine to malfunction and catching fire immediately. On June 6, 2014, GM issued another recall on the 2015 Tahoe and Yukon because their radio control modules may not work, and thus prevent certain audible safety warnings.

Changes by year

2015 mid-year update

The Tahoe received 4G LTE, Wi-Fi, and Siri capability, a new color palette, Brownstone Metallic, and added a hands-free power liftgate feature that is standard on LTZ, but included on LT with the optional Luxury Package. The MyLink with Navigation feature became standard on the LTZ trim, while E85 capability is removed from retail orders.

The Yukon, in addition to receiving the aforementioned features, saw the 6.2-liter EcoTec3 V8 engine being updated with the new 8L90E eight-speed automatic transmission for the interim model year, allowing it to improve fuel economy.

A body-colored painted Shark Fin antenna was added with the 2015 mid-year refresh for all models.

2016

For the 2016 model year, the Chevrolet Tahoe received more upgraded changes and new features, similar to the ones added to the Suburban. The changes included power-adjustable pedals, forward collision alert, IntelliBeam headlamps, lane keep assist, and a safety alert seat as part of the newly introduced enhanced driver alert package as an available option on the LS trim. The inside floor console with storage-area SD card reader was removed and a new infotainment system was introduced, officially ending the CD player era for the Tahoe; the 8-inch MyLink feature was expanded to the LS trim and became standard (replacing the 4-inch display), although the navigation feature remains as an option on LT and standard on LTZ. A new liftgate shield was added to the Theft Protection Package, along with the new lane keep assist which replaced the lane departure warning. The capless fuel fill tanks became standard on all trims. Siren Red Tintcoat and Iridescent Pearl Tricoat became the new color trims, replacing Crystal Red Tintcoat and White Diamond Tricoat. The instrument cluster was re-configured with a new multi-color enhancement and a heads-up display was introduced as a standard only on the LTZ trim.

The 2016 GMC Yukon also saw similar changes, with liftgate, power, hands-free now packaged on SLT trims, a free-flow feature that replaced the Premium package, and two new premium colors (Crimson Red Tintcoat and White Frost Tricoat) replacing Crystal Red Tintcoat and White Diamond Tricoat respectively.

The 2016 Tahoe came equipped with both Apple CarPlay and Android Auto Capability features. However, only one of their phone brands at any one time can be used. The 2014 and 2015 LTZ and Denali packages came equipped with a "wireless" charging accessory. while the Android Auto option will only be available on LT and LTZ trims featuring 8 inch screens.

In 2015, the Russian-built Chevrolet Tahoe received the 6.2L V8 L86 EcoTec engine, which was the only engine offered in the region as an exclusive to the Russian and CIS markets only, as GM had no plans to make it available to North America.

2017

For the 2017 model year, Chevrolet made upgraded changes to the Tahoe. New additions include the teen driver feature, the App Store feature, a rear seat reminder, and low speed forward automatic braking. Two new colors, Blue Velvet and Pepperdust Metallic, were added to replace four colors. The 22-inch wheels option was expanded to three, and the rear seat entertainment system was overhauled. Chevrolet also made changes in the level trims, with the c-pillar badge now removed from LS models and the LTZ trim is renamed to Premier, which will continue to be the top-of-the-line model.

The 2017 model year Yukon also received similar changes, but with a few exceptions. Two new colors, Dark Blue Sapphire Metallic and Mineral Metallic were introduced, the latter exclusive to the Denali, which is also adding a new 22-inch ultra bright aluminum wheels with midnight silver premium paint and a head-up display to its features. The interior backlights changed from red to blue. The heated and vented driver and front passenger seats are now standard on the SLT and Denali trims.

2018

For the 2018 model year, the 6.2-liter EcoTec3 V8 engine became available in the Tahoe RST (when bought with the Performance Package). All 2018 Tahoe and Suburban trim levels came standard with LED daytime running lights, replacing the high beam projector DRLs on LS and LT trim levels. The 2018 Tahoe was also available with the Custom Edition package for the base LS trim level. The Chevy Tahoe LS trim level featured a chrome grille, 18" painted aluminum wheels, 18" all-season blackwall tires, and third-row seat delete (reducing seating capacity to 5 from 8) if ordered with the Custom Edition package. The GMC Yukon received a 10-speed automatic transmission on the Denali trim level and the GMC Yukon is facelifted for 2018 with a refreshed grille similar to the one from the 2017 GMC Acadia and 2018 GMC Terrain.

2019

The 2019 Tahoe/Yukon saw only minor changes. One exterior color, Shadow Gray Metallic, replaced both Havana Metallic and Tungsten Metallic, and the Premier model received a newly redesigned badge on the liftgate.

2020

The 2020 model year Tahoe/Yukon was shortened to make way for the upcoming fifth generation. From the Tahoe, the All Season Package and the LT Signature Package were removed, along with the Pepperdust Metallic exterior color, while the 2020 GMC Yukon replaced its Pepperdust Metallic color with Carbon Black Metallic with no additional changes.

On December 10, 2019, Chevrolet introduced a fifth-generation Tahoe at Little Caesars Arena in Detroit, Michigan. This time around, GM chose to introduce the Chevrolet full size SUVs first, followed by the GMC Yukon in January 2020 and the Cadillac Escalade in February 2020. Following the industry shutdown due to the coronavirus pandemic, the SUVs started production at the Arlington plant on May 18, 2020, and arrived in dealerships in June 2020.

Tahoe

Based on the same GMT T1XX platform as the Silverado 1500, the Tahoe distinguishes itself by swapping that truck's live axle and leaf springs for an independent rear multilink suspension setup with coil springs, thus lowering the floor of the vehicle and creating more room in both the cargo area and the second-and third-row seats. The Tahoe expanded its length to 210.7 in (5,352 mm), and the wheelbase to 120.9 in (3,071 mm), making it the largest SUV in the full-size length segment. It gains 11 cubic feet (0.31 m³) of cargo space behind the third row and 10 in (254 mm) of third-row legroom.

Carryover trims include the basic LS, LT, and Premier, with Z71 and RST moving from package to trim level, along with the newly-added top-of-the-line High Country trim, giving the Tahoe the highest number of trims of any vehicle in its segment. Quad exhaust tailpipes are available on LT and standard on Premier and High Country.

Although the Tahoe retains a boxy look, it adds a more rounded design and adopts the same Chevrolet design language as the Silverado, featuring a sharply curved front grille and LED lighting. The Tahoe nameplate is given greater prominence, being placed front and center on the higher liftgate.

The dashboard and entertainment system have been fleshed out, moving away from the traditional design. Newly updated features include a 10.25-inch touch screen that is now standard on all trims and a pair of 12.6-inch LCD rear screens that can play movies and offer content from passengers’ smartphones and can play different programs on the two screens. A new push-button shifter column (P, R, N, D) is placed on the dashboard, nine camera displays for enhanced towing capabilities, and a total of 30 additional safety features have been implemented throughout the Tahoe. An Air Ride Adaptive Suspension is standard on the higher trims, likewise with an 8-inch driver screen.

It also features a Duramax diesel engine as an option (available on all trims and packages except for the Z71) for the first time; a 3.0-liter I6 which produces 277 hp (207 kW; 281 PS) and 460 lb⋅ft (624 N⋅m) of torque, a segment-exclusive. The fifth generation Tahoe went on sale in the second half of 2020 as a 2021 model.

Although GM had been making plans to bring the Tahoe to right-hand-drive countries for the first time, those plans were temporarily put on hold for the Australasian region because of low demand for large SUVs and a local company (expected to be Holden Special Vehicles) that was prepared to do the conversions focusing on other productions.

In November 2020, GM announced that its large SUV lineup would be imported to China, marking the Tahoe and Yukon Denali's maiden entry into the country, starting with the 5th generation models.

In November 2021, GM announced that it would begin selling the Chevrolet Tahoe in South Korea starting for the 2022 model year, surpassing the Chevrolet Traverse as the largest Chevrolet vehicle in that East Asian country's Chevrolet lineup. The Korean-spec Tahoe is exclusively available in the High Country trim level, powered by the 6.2L L87 V8 petrol engine. Just like with the Mexican-spec Chevrolet Tahoe, the Korean-spec Tahoe is not available with the Duramax l-6 diesel engine. All Korean-spec Tahoe SUVs are manufactured at the Arlington Assembly plant. Sales of the Tahoe in that country began on April 18, 2022.

2025 facelift

In November of 2023, GM unveiled facelifted versions of the fifth-generation Chevrolet Tahoe and twelfth-generation Chevrolet Suburban. The facelifted Tahoe features refreshed front and rear facias with redesigned headlights and taillights similar to those from the 2024 Chevrolet Traverse. Other changes include new 24-inch wheels, a new upgraded 3.0L Duramax diesel engine option with 10 percent more horsepower than the current Duramax diesel engine option (with the new upgraded 3.0L Duramax diesel engine option being available on the Z71 trim level for the first time), a new revised interior with an all-new standard 17.7-inch-diagonal freeform infotainment screen paired with the 11-inch-diagonal driver information center and redesigned center console, new ride and handling enhancements, upgraded safety and technology including GM Super Cruise, and improved towing and trailering technology. The facelifted fifth-generation Chevrolet Tahoe and twelfth-generation Chevrolet Suburban models will go on sale in late 2024 as 2025 model year vehicles.

Yukon

GMC unveiled its fifth-generation Yukon in Vail, Colorado on January 14, 2020, alongside its extended size sibling Yukon XL. Like the Tahoe, the Yukon will also feature an independent rear suspension, a 3.0-liter inline-six turbodiesel engine, and a top-shelf suspension option featuring air springs and magnetic-ride shocks, a standard 5.3-liter V-8, an optional 420 hp (310 kW) 6.2-liter V-8, and a 10-speed automatic transmission that is standard across the lineup. It also gains 4.9 inches in the wheelbase. The dashboard will have two versions, one similar to the Tahoe while a different one with a larger entertainment screen will be exclusive to the Denali. The Yukon's design follows GMC's design language, with the front grille mimicking the Sierra but the tailgate mimicking the GMC SUV lineup with the lights extended to the tailgate doors.

The lineup of level trims also expanded as well, with the SLE, SLT, and Denali now joined by the 4WD-exclusive AT4, the latter of which comes standard with the Magnetic Ride Control electronically adaptive dampers, AT4-exclusive leather-appointed seats, and stitching with a unique Jet Black interior color and Brandy accents, a heated steering wheel, heated and ventilated front seats, heated second-row outboard seats, a two-speed transfer case, 20-inch Goodyear all-terrain tires, Traction Select System with off-road mode, hill descent control, and skid plates.

The fifth-generation Yukon debuted in July 2020 as a 2021 model.

GMC Yukon Denali

The fifth-generation Yukon Denali was introduced in January 2020. The updated and redesigned vehicle was moved upward in its top-of-the-line level trim, because of the introduction of the AT4 that was slotted above the SLT level. It also featured a dashboard design exclusive to this trim.

Recalls/safety issue

On August 3, 2020, GM sent out a new TSB (Technical Service Bulletin) that addresses a potential issue related to the engine oil cooler lines on the 2021 Tahoe and Yukon. The issue was sent out to dealerships ahead of receiving the vehicles and were instructed to inspect the engine oil cooler lines at the quick connector on the radiator in order to ensure they are properly seated before selling or dealer-trading the vehicle. No parts were needed for replacement but cautioned customers to have it checked as catastrophic engine failure could occur if not repaired.

Hybrid vehicle

GMC Yukon Hybrid

The Tahoe made its hybrid electric debut in late 2007. In January 2008, the starting price was United States dollar 50,540. The starting price of the 2009 model was increased to United States dollar 51,405.

The Chevrolet Tahoe Hybrid uses a combination of its 6.0L V8 engine that can also run on V4 mode and two 60 kW (80 hp) (continuous) electric motors with a 300-volt, 1.53 kWh nickel–metal hydride battery. The vehicle can run on either gasoline, electricity, or a mixture of the two using its automatic Two-Mode Hybrid system that monitors the vehicle's torque and state of the battery to choose the most efficient source of power. The battery is charged either directly by generating electricity through driving one or both electric motors using the gasoline engine (while the vehicle is coasting or being driven by the gasoline engine), or by the wheels driving one or both electric motors through regenerative braking when the vehicle is decelerating, thus regaining some of the energy invested in forward momentum. The Tahoe is considered a strong or full hybrid, in that it can run entirely on the battery (for a limited range) at low speeds. In city driving, the EPA rating of fuel consumption for the 2WD version of the hybrid is 21 mpg_‑US (11 L/100 km; 25 mpg_‑imp). In comparison, non-hybrid varieties of the Tahoe are rated no higher than 15 mpg_‑US (16 L/100 km; 18 mpg_‑imp) in city driving. In highway driving, the EPA rating is 22 mpg_‑US (11 L/100 km; 26 mpg_‑imp).

The Tahoe and Yukon Hybrid models were discontinued after the 2013 model year as GM moved to make its SUVs more fuel-efficient with the introduction of the EcoTec engine that would later be installed in the 2015 Tahoe and Yukon.

Outside the United States

In Brazil, the Tahoe GMT400 was sold under the name of "Grand Blazer", sourced from Argentina with rear-wheel drive only, regionally-sourced 6-cylinder engines (the late-type 4.1L MPFI Chevrolet straight-6 gasoline and the 4.2L MWM Sprint 6.07T diesel) and manual transmission. The GMT400 is used by Brazilian elite police units, such as the BOPE (Batalhão de Operações Policiais Especiais) in Rio de Janeiro and the ROTA (Rondas Ostensivas Tobias de Aguiar) and GATE (Grupo de Ações Taticas Especiais) in São Paulo. It is also used by the São Paulo State Police and the Rio Grande do Sul State Police. But as the cars grew old, the great majority of them were substituted, mainly by the smaller Chevrolet Blazer midsize SUV. The Tahoe name was not used in Brazil because it would be unfamiliar to most Brazilians since it refers to the Lake Tahoe on the border of Nevada and California.

Elsewhere in South America, Chile has incorporated the Tahoe as a transport vehicle for the special operations unit (GOPE) of the Chilean Police (Carabineros de Chile) to carry communication equipment.

The Tahoe was also assembled in Venezuela from CKD kits for three generations, being phased out in 2014 along most of the local Chevrolet range due to unfavorable economic conditions and political circumstances. The fourth generation of the Tahoe has not been available in Venezuela.

In Ecuador, due to the tax benefits offered by hybrid vehicles, the third-generation of the Tahoe was offered only in the hybrid version until 2011. A review of the benefit to exclude hybrid vehicles with a displacement greater than 1.8L rendered the Tahoe Hybrid less cost-effective than the non-hybrid in Ecuador.

In November 2023, it was announced that the GMC Yukon would launch in Australia in 2025, as part of the GM-operated General Motors Special Vehicles business.

In North America, the Tahoe is used by many law enforcement agencies, fire departments, and EMS agencies. Prior to the announcement of the Z56 police package model, the civilian base and LS models based on the GMT400 were used in police service. During the 1997 model year, the Tahoe was offered with the Z56 police option using suspension components from the discontinued 454SS truck – the first Tahoe Z56s were available only in 2WD until the GMT400 was phased out. The original prototype had rear disc brakes based on the B-body 9C1s whereas the production Z56s came with rear drum brakes. Plans for outfitting the Tahoe with the Z56 police package originated around the 1994 model year when GM broke news about phasing out its B-platform sedans (Caprice, Impala SS, Roadmaster) at the end of the 1996 model year where a replacement was imminent since GM ended production of its body-on-frame passenger sedans amid growing SUV sales. Since the introduction of the GMT900, Chevrolet currently offers two versions of the police package Tahoe: a four-wheel-drive version and a two-wheel-drive version. Just like the GMT400-based models, civilian GMT800 Tahoe base and LS models were also used for police use until the Z56 police package option was reintroduced in 2004 late in the GMT800's life cycle by some agencies.

Chevrolet refers to the four-wheel-drive (4WD) version as "Special Service Vehicle" (SSV) which has the 5W4 RPO code. This version of the Tahoe can be used for all purposes except pursuits and high-speed responses because of its high center of gravity just below the front window (height, not location), thus having a higher probability of rolling-over at high speeds. This version is preferred by agencies where snow, ice, flooding, rough terrain, and ground clearance are common issues.

Chevrolet refers to the two-wheel-drive (2WD) version—also known as the rear-wheel-drive (RWD) version—as "Police Pursuit Vehicle" (PPV). This version can be used for all purposes including pursuits and high-speed responses. The center of gravity in this vehicle is lower than that of the four-wheel-drive version and the ground clearance is about 1 in (25 mm) less, with a standard rear bumper replacing the tow hitch on civilian Tahoes. Highway patrol agencies prefer the two-wheel-drive version, where pursuits and long-distance responses are more common. As of the 2012 model year, the Tahoe was the last body-on-frame, rear-wheel-drive police vehicle manufactured for the United States market since Ford phased out its aging Panther platform. Other SUVs like the Ford Expedition are used by many law enforcement and EMS agencies, but are not pursuit-rated.

Chevrolet built a 2015 Chevrolet Tahoe Police Patrol Vehicle that was previewed as a concept at the 2013 SEMA Show in Las Vegas. The vehicle became available in 2WD and 4WD drivetrains with orders coming in the first quarter of 2014 for special service models, followed by the orders for the police pursuit models afterwards.

2021 PPV

The 2021 Tahoe PPV marks the most drastic change from the standard Tahoe. Rocker covers are borrowed from the GM LT4 engine found in high-performance Corvettes, Camaros, and Cadillacs. Engine and transmission coolers are PPV-specific. Bridgestone co-developed Firehawk Pursuit tires with GM for the 20-inch steel wheels. Six-piston, 16-inch rotor Brembo brakes are standard-issue on the PPV. The suspension is lowered and further fortified. All-wheel drive is standard and sent to the front as needed with a limited slip clutch in the transfer case. The alternator almost doubles the amperage of the standard Tahoe. This version of the PPV uses the 9C1 code instead of the Z56 code.

Unlike the standard Tahoe, the 2021 Tahoe PPV (along with the related Commercial/Fleet model) includes a standard eight-inch Chevrolet Infotainment touchscreen in lieu of the 10.25-inch unit found on all other models. It also does not include wireless Apple CarPlay or Android Auto (although still offers wired versions of both), SiriusXM Satellite Radio with 360L, or the Google-based operating system (on 2022 and newer models). A standard 4.2-inch color LCD screen is also included with an analog instrument cluster in lieu of the ten-inch full-color LCD instrument cluster on 2022 models.

When production of the CUCV II ended in 2000, GM redesigned it to coincide with civilian truck offerings. The CUCV nomenclature was changed to Light Service Support Vehicle in 2001. In 2005, LSSV production switched to AM General, a unit of MacAndrews and Forbes Holdings. The LSSV is a GM-built Chevrolet Silverado 2500 HD, Chevrolet Tahoe, or Chevrolet Suburban that is powered by the 5.3L V8 for the Tahoe, 6.0L V8 for the Suburban, and a Duramax 6.6L V8 turbo diesel engine for the pickup trucks. As GM has periodically redesigned its civilian trucks and SUVs since 2001, LSSVs have also been updated cosmetically.

The militarization of standard GM trucks/SUVs to become LSSVs includes exterior changes such as CARC paint (Forest Green, Desert Sand, or 3-color Camouflage), blackout lights, military bumpers, a brush guard, a NATO slave receptacle/NATO trailer receptacle, a pintle hook, tow shackles and a 24/12-volt electrical system. The dashboard has additional controls and dataplates. The truck also can be equipped with weapon supports in the cab, cargo tie down hooks, folding troop seats, pioneer tools, winches, and other military accessories. In the Canadian Army, these vehicles are nicknamed "Milverado."

The Enhanced Mobility Package (EMP) option adds an uprated suspension, 4-wheel anti-lock brakes, a locking rear differential, beadlock tires, a tire pressure monitoring system and other upgrades. About 2,000 LSSV units have been sold to U.S. and international military and law enforcement organizations.
