Features

• The Infiniti EX is the first production automobile to offer an Around View Monitor (AVM), which utilizes small front, side and rear-mounted cameras to give the driver a "top-down view" of the outside of the vehicle while parking - helping to reduce blind spots while parking.
• The EX is also one of the first production automobiles to feature "Scratch Shield, " a "self-healing clearcoat paint. The paint self-repairs fine scratches, such as fingernail scratches under door handles, restoring the EX's surface close to the original state. The process, which takes anywhere from one day to one week (depending on the surrounding temperature and the depth of the scratch), is accomplished through the use of an elastic resin. It is combined with a conventional clearcoat to increase the paint's flexibility and strength by raising the resin density."
• The EX becomes the second Infiniti production vehicle, following the 2008 Infiniti M series, to offer the Lane Departure Prevention (LDP) system. This utilizes the electronic stability control system to help assist the driver in maintaining lane position by applying gentle brake pressure on each wheel individually to generate intended movement. It sounds an alert and nudges the vehicle in the correct direction when lane departure is detected. It also applies braking actuation to bring vehicle back in the lane.

Reception

GQ magazine named it one of the 10 best luxury SUVs three years in a row.

The EX (later renamed to the first-generation QX50) was not a sales success, however, due to its limited interior room compared to other compact crossovers.
