Owner report 11495858 · 2022-12-02 (December 2, 2022)
This is the 3rd instance of my car rolling backwards down the driveway. Both the first and second instances of uncontrolled rolling happened in 2016. Only the second instance was caught on camera. I shared the video with Infiniti and was instructed to bring the car in for an inspection. I went in for the inspection in December 2016 and they reported that there were no issues (despite video evidence). Today, December 2, 2022, the car (while gear shifted into park) again rolled down the driveway, across a street and hit my neighbor's house. This …

FROM A COLD START,DRIVING VEHICLE A SHORT DISTANCE APPROX.( 1 MILE ) PULLING INTO A PARKING SPACE. STEP ON BRAKE PEDAL, ENGINE IDLE INCREASES MAKING YOU PRESS HARDER ON THE BRAKE PEDAL.

THIS HAS HAPPENED SEVERAL TIMES. THIS EXCESSIVE BRAKING HAS ALSO HAPPENED AT A TRAFFIC SIGNAL LIGHT. CONCERN IS ALWAYS TO BE READY WITH A HEAVY FOOT ON THE BRAKE PED…

Owner report 11598791 · 2024-07-04 (July 4, 2024)
I was driving and came to a red light behind other cars. I was completely stopped with brakes applied and vehicle suddenly lurched forward, RPM’s reved up over 3,000 without me accelerating. I was about two blocks from home and was able to make it by slowly driving and jerking all the way. Mechanic codes were 720 output speed sensor. Very alarming situation! I could have easily hit the car in front of me if I would have been any closer, or worst yet a pedestrian! Appears to be critical safety issue and something that may need to be recalled…

HE SAID WE WENT FROM ALMOST IN THE STOP POSITION TO HIGH SPEED LIKE A CRASH TEST DUMMY VEHICLE. THIS ALL OCCURRED IN A SMALL PARKING LOT IN THE CITY. THE IN…
