My car suddenly accelerated out of my control and my car was totaled in a supermarket parking lot. Amazingly no serious injuries though two other cars were damaged by this event. No warnings and no time to act. I demanded that Nissan do an inspection. The email I got from them this morning said they found nothing wrong with the vehicle BUT that the accelerator was at 100% at the time of the accident. I was parked and getting out of my car when this occurred but Nissan did not think it suspicious that my car accelerated to 100% without any reason for me to accelerate and my foot not on the power pedal. Their letter to me claimed no responsibility for the malfunction. In fact. They are claiming no malfunction at all. I have requested in writing to get all the data they collected and although they had previously agreed to provide it to me. They are now backpedaling on that now that I’ve posed legitimate questions. This happened TWICE in a 15 month period and the last accident destroyed my car. Everyone was eager to blame me for the first accident that did thousands of dollars damage, which I know for a fact I was parked in my own driveway and not even driving. It was scary and stressful and still is. The only thing I can feel good about is that the car, my beautiful LEAF, is off the road forever and will not be dangerous any longer to me or anyone else.

HI, WHEN I PUT THE CAR IN REVERSE YESTERDAY MORNING IT SPED OUT OF THE GARAGE WITH NO THROTTLE AND WAS VERY DIFFICULT TO BRAKE. TURNS OUT THE BRAKE, ABS, WARNING AND TRACTION CONTROL LIGHTS WERE ALL ON. THROTTLE BEHAVIOR IN DRIVE WAS NORMAL BUT WAS ALSO REALLY HARD TO BRAKE. THERE WAS ALSO A WEIRD HUM AT POWER ON. I POSTED THIS TO THE R/LEAF FORUM ON REDDIT AND EVERYONE SAID REPLACE THE 12V BATTERY WHICH FIXED IT. OTHERS DESCRIBED SIMILAR EXPERIENCES.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2014 Nissan Leaf (53 Kwh Battery) Bev verdict →
