On [XXX], I was slowly pulling into my driveway, took my foot off the accelerator and turned the steering wheel slightly to the right as the driveway is L shaped. Suddenly, the car sped up towards the garage door. I looked down quickly to see if I’d somehow pressed the accelerator by accident but I had not. I slammed on the brakes as hard as I could but the car kept going and smashed into the garage door and the corner of the garage, causing close to $20k in property damage. The hood and front bumper were badly caved in at the point of impact and pieces of the undercarriage were on the ground. The air smelled like rubber and there were tire marks on the driveway here I had slammed on the brakes. The airbags did not deploy. The Automatic Braking System did not work. There were no warning messages or lamps. The only unusual symptom that I noticed was that on my way home from Kona, when I was pulling up slowly to a traffic light, the car seemed to hesitate a couple of times, which seemed odd but not severe enough for me to be concerned about a wreck. That occurred about a half hour before the incident. I was not physically injured but I have been very shook up and depressed since the incident. If this had happened on the highway, I could have been killed and the car could have killed others on the road. I reported the collision to USAA immediately and, on their advice, I had it towed to Kona Nissan, the dealership where I purchased the vehicle and where I have had it serviced. The expectation was that they would perform diagnostics on the vehicle but they won’t touch it, nor will they talk to USAA. I had taken the car in when it was recalled for the VCM issues and I don’t believe it was fixed properly. Or the repair wasn’t effective. The car is at Gerber Body Shop in Kona, Hawaii. Please arrange inspection with them. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The incident occurred at a stop sign where I was waiting behind one other vehicle. The vehicle ahead of me accelerated from the stop sign to turn into traffic, but abruptly slammed on their brakes. I had began accelerating up to the stop sign and was unable to stop before impacting the car in front of me. As soon as I saw the vehicle was braking, I immediately slammed on the brake pedal. Braking did not immediately occur. My wife said she was afraid that I had slammed the gas pedal because she could hear my foot hit the brake pedal and neither of us felt any braking. The Nissan Leaf was in Eco Mode and ePedal at the time of the incident. I believe that the transition from regenerative braking to mechanical braking delayed the stopping of my vehicle. We were lucky that this happened in a very low consequence situation, but if this happened with a pedestrian or at a higher speed where emergency braking is required, this delay in braking could be dire. In addition, this vehicle is equipped with automatic emergency braking. I have heard this feature go off before in this specific car when a car is braking faster than I am. In this case, the alarm and assisted braking did not go off, despite a car stopping within extremely close proximity.

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 2018 Nissan Leaf (40 Kwh Battery) verdict →
