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]
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]

Introduced in the first quarter of 2021 for the 2022 model year, the QX55 is a "coupé SUV" version of the QX50 with a more sloped roof design. Infiniti intends it to be the spiritual successor to the FX.[28][29]

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]
The 2020 QX50 was tested by the Insurance Institute for Highway Safety.[39]
