The Jeep Liberty (KK), or Jeep Cherokee (KK) outside North America, is a compact SUV that was manufactured by Jeep and Introduced in 2008 as a successor to the first generation Liberty (KJ). The Liberty features unibody-construction and was assembled at the Toledo North Assembly Plant in the United States and other countries including Egypt and Venezuela. In 2010 Jeep estimated that 70% of Liberty buyers were first time Jeep owners.

Description

The Jeep Liberty received a complete redesign for the 2008 model year with a more boxy and utilitarian look, like that of the 2007 Dodge Nitro, the latter of which lasted until its final production in December 2011. The 2008 Liberty debuted at the 2007 New York International Auto Show.

With the smaller Patriot and Compass crossover SUVs now available to cater to MPG-conscious buyers, the four-cylinder diesel engine was dropped from the Liberty's offerings. The iron-block, aluminum-head V6 was the only engine available for 2008. Towing capacity was 5,000 lb (2,268 kg). Jeep discontinued the Liberty CRD for the American market because it would not meet tougher 2007 emissions standards for diesel engines. Between 2008 and 2010 the Jeep Liberty KK was sold in the European market with a 2.8 L diesel engine producing 175 hp and 302–339 lb ft of torque. The Inline 4 cylinder turbo diesel engine is manufactured by Italian diesel engine manufacture VM Motori.

Transmission choices were both carry-overs: a six-speed manual or a four-speed automatic. Standard equipment included electronic stability control with roll mitigation, traction control, and anti-lock brakes with brake assist. New Features included standard side airbags. Optional features are rain-sensing wipers, Sirius Satellite Radio, Bluetooth, a navigation system, and the MyGig entertainment system, complete with a 30GB hard drive.

2010 Jeep Liberty Renegade

Two models were offered initially, the base "Sport" and a higher-trimmed "Limited." Wheel choices included several 16-, 17- and 18-inch designs. Among the more distinctive features was the Sky Slider, a power roof made from "reinforced acrylic cloth" over the front and rear seats. The Sky Slider retracted to an 60 inches (1,500 mm) by 30 inches (760 mm) opening that was the largest in its class. Jeep claimed that the idea behind the Sky Slider was to give consumers the open-air feeling from previous Jeep models while maintaining the rigidity and safety of a sturdy frame.

The 2009 Liberty appearance was unchanged from the 2008 models. Upgrades included stiffer rear axle shafts and re-tuned springs, shocks, anti-roll bars, steering gear valve, low rollback brake calipers, and a revised brake pedal ratio. The six-speed manual transmission was dropped, and the four-speed automatic was now standard.

2011 Restyling

For the 2011 model year, the Liberty KK received a mid-cycle restyling. While the general exterior design remained identical to the 2008-2010 model, the interior was restyled to be similar to that of the all-new 2011 Jeep Grand Cherokee (WK2), with a new steering wheel, and revised infotainment systems that now included wireless stereo audio streaming (A2DP) in vehicles equipped with U Connect Bluetooth (the top-tier Limited and Limited Jet Edition trims received this feature as standard equipment), and a Park View rear view backup camera became available for vehicles equipped with touchscreen infotainment systems. The mid-level Limited trim was shelved for retail buyers, and a new Limited Jet Edition was introduced to take its place. The Limited model, which remained available for fleet buyers (such as rental companies), received a higher level of standard equipment, including leather seat trim, heated front seats, the 368-watt, eight-speaker Infinity premium amplified audio system with a subwoofer, and U Connect Bluetooth. A 'SINCE 1941' embossing was added to the interior to celebrate Jeep's 70th Anniversary, and a special 70th Anniversary Edition model was also offered. Three new trims, Sport Jet Edition, Latitude, and Limited Jet Edition, were introduced midyear.

Discontinuation

In June 2012 Chrysler announced the Toledo North Assembly Plant in Toledo, Ohio, where the Liberty is manufactured, will temporarily shut down on August 21, 2012, in order to prepare for the launch of the new Jeep Cherokee. Production was to start in late spring 2013, following the introduction of the new Cherokee at the 2013 New York Auto Show.

The second generation Liberty ceased production to make way for the reintroduction of the new Cherokee. The final 2012 model Jeep Liberty rolled off the assembly line on August 16, 2012.

Recalls

On June 7, 2011 Chrysler issued a safety recall on the 2011 model Jeep Liberty because they were possibly built with a missing or incorrectly installed steering column pivot rivet. On July 14, 2011 Chrysler issued another recall calling another 11,000 vehicles in for inspection.

On December 7, 2011 Chrysler issued a Customer Satisfaction Notification recall on Jeep Liberties manufactures between 2010 and 2011 equipped with power door locks. The malfunction caused the right front and right rear door locks to make a ratcheting sound while using the power door locks.

On July 2, 2013 Chrysler issued the first of several recalls addressing the Active Head Restraints failing to deploy during a rear end collision. The recall was issued on nearly half a million vehicles manufactured through January 14, 2013. Among them were the 2011 and 2012 Jeep Liberty. Three other recalls up until 2017 were issued concerning the same issue.

The Jeep Liberty KK was also a subject of the infamous Takata air bag recall that affected millions of vehicles from multiple manufacturers. According to the recall, "In the event of a crash necessitating deployment of one of the affected frontal air bags, the inflator could rupture with metal fragments striking and potentially seriously injuring the vehicle occupants."

Fleet and government Use

Since it was redesigned in 2002 to the time it was discontinued and replaced by the Cherokee KL in 2012, the Liberty KK found its way into rental car fleets, most vehicles being base-model Sport models in 2WD or 4WD.

Many government and police fleets also used the Liberty KK. The models were base-model Sport models with 4WD.
