“Unintended acceleration. Pulling into a parking space in a shopping center parking lot, after going over a speed bump and making a left hand turn into the spot the car accelerated and would not stop. Pushing on the brakes did not work. Car has a system to prevent crashing in to an object in front of the car but that did not work. The car struck a pole in the parking lot doing significant damage to the right front of the car.”

NHTSA complaint #11268861, filed 2019-10, 2,000 miles

“I have 3 issues with the car. The braking issue presented itself last in time but is most important relative to safety. Around mid January 2022, my car, while I was driving, and without any notice, began to decelerate/brake for no reason. My car is equipped with front driver assist but there were no cars, hazards, in front of me. It was a clear, dry day and the car was warm. It was momentary and fortunately no one was behind me. The car beeped, but there was no other warning. The second time this same event happened, however, the accelerator pushed back against my foot. …”

NHTSA complaint #11451597, filed 2022-02

“Vehicle is tramaling or wandering at 50+ mph speeds. Making it dangerously difficult to keep between the lines without constant steering corrections. I have had car aligned and changed the tires. Still issue persists. There are several post online about this issue with the infiniti Q60 and Q50 models.”

NHTSA complaint #11636939, filed 2025-01

“Early turbo failure should be extended to newer vehicles not only up to 2018. I am experiencing turbo failure and there is no extended warranty for this repair.”
