The Infiniti QX50, marketed also until 2013 as the Infiniti EX (North America) and Nissan Skyline Crossover (Japanese Domestic Market|JDM), is a front- or all-wheel drive, five passenger, five-door compact luxury crossover SUV, manufactured and marketed by Infiniti, Nissan's luxury division over three generations: one generation as the EX followed by two QX50 generations.

The EX (MY 2008-2013) was the first production automobile equipped a surround-view camera, marketed as Around View Monitor.

The first generation QX50 was a minor model update of the EX with its nameplate changed to QX50 to align with the marque's new Q and QX nomenclature introduced for model year 2013 (China) and model year 2015 (United States). The second-generation QX50 entered production in November 2017 as a 2019 model.

Transmissions include manual shift mode that includes the option of sequentially selected manual gearshifts and Downshift Rev Matching (DRM). U.S. models include a choice of RWD or ATTESA E-TS AWD. Models sold in Canada, Europe include ATTESA E-TS AWD as standard.

The Infiniti EX35 line has a 0-60 mph (97 km/h) time of 5.8 - 6.2 seconds.[clarification needed] The quarter mile is 14.6 seconds at 98 mph (158 km/h), and top speed is electronically limited to 144 mph (232 km/h). 70 mph (113 km/h) - 0 braking is a 166 feet (51 m). Roadholding is .83g.[7]

Features

[edit]

The EX was the first production automobile to offer a surround-view camera, marketed as Around View Monitor. The cameras are located at the front, back and sides of the vehicle and feed images to an image processing unit; those individual inputs are analyzed, synthesized to offer a synthetic, but positionally accurate, somewhat lifelike top-down view of the car and its surroundings.[8][9]

The EX was 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."[3]

The EX was the second Infiniti production vehicle, following the 2008 Infiniti M series, to offer the Lane Departure Prevention (LDP) system.[10] 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.[11] It also applies braking actuation to bring vehicle back in the lane.[10]

KR20DDT engine NHTSA investigation

[edit]

On December 13, 2023, the NHTSA opened an investigation into customer complaints of engine failure in the Nissan's KR15DDT and KR20DDET engines, the latter being used in the J55 QX50. The complaints allege engine failure, loss of motive power, engine knock, or noise and/or metal chunks and shavings being found in the oil pan of vehicles with these engines.[37] The cause appears to be seizures and damages to the main bearings and L-links.[38] Nissan stated that they are attempting to address these failures by changing their manufacturing process.[38]
