What 63 owners told NHTSA about the 2018 Nissan Leaf (40 Kwh Battery)

Our 2018 Nissan Leaf experienced an error message when we tried to start it saying "Warning Service EV System No Power". Mileage: 29,862. It would go into neutral, but not into drive. We called GEICO to have it towed to dealership Leith Nissan on [XXX]. On [XXX], John Day from Leith Nissan called to request permission to install a new 12V battery. I approved the cost of replacing the battery. They said that they were able to drive the car after the 12V battery was replaced. But then they plugged it into the charger, and got an error message "EV System No Power", and they couldn't drive it anymore. Sometime after that there was a thermal event that caused the Power Distribution Module to explode and for soot to pour out of it. These incidents are described by the technician Ryan in these videos [XXX] Nissan indicated that the electric power train is no longer under warranty. Our Q:When did you receive the car? ([XXX] repair order opened [XXX]) When did you first start working on the car? [XXX] When did the thermal event occur? (unsure of occurrence date) When did you replace the 12 volt battery?

I was pulling slowly into a parking spot. The vehicle accelerated all of a sudden on its own very fast. I slammed on the brakes and the vehicle did not stop. It ran us on a sidewalk and crashed into a pole. Luckily no one hurt. Progressive is calling the car a total loss, but they have done nothing The car is still at a parking lot near the crash. Nissan is also doing nothing. I feel that I deserve better treatment. I have a good driving record and my rates are going to go up. I have not been offered a replacement car. The car is very dangerous and I would never drive another Nissan

I was stopped at a light, in a long line of cars, my foot on the brake, a few feet away from the car in front of me, and the same in back. All of a sudden, the car started moving, accelerating, jerking forward. I was shocked, pushed down on the brake, nothing happened. starting pulling the car out of line because I was going to hit the car in front of me. I was pumping the brake, and NOTHING HAPPENED. Clipped the car in front's rear left bumper, wrecked my front right bumper. Finally pulled into the turn lane and finally the brakes caught. It was like someone had taken a gizmo and turned on my car (like the OnStar mess a few years ago.). Nothing like this has ever happened to me, in any car, including this one, until 5/12 at 2:00 pm. It was terrifying.
