“My vehicle will phantom brake and kick on the automatic emergency brake system without cause. It has done it as I was accelerating onto the freeway onramp and almost caused a collision with the vehicle behind me. There was nothing in front of me and no reason to brake. It has happened on several occAsions”

NHTSA complaint #11651508, filed 2025-03

“While sitting stopped at a red light, the brake pedal suddenly became soft and the vehicle began moving. As I rushed to depress the pedal further (all the way to the floorboard - which did not stop the car) the car rolled forward and collided with the car in front of us causing damage to both vehicles. If the other car had not been in front of us we would have rolled directly into heavy active cross traffic which would have caused significant harm to all inside. My daughter, niece, and 8 month old grand-niece were with me in the car.”

“I was at a red light with the idle stop automatically triggered. When the light turned green, and I pressed the accelerate pedal, the car would not move. I looked and saw the car had shifted itself to N (neutral) when it should have stayed at D (drive). I pressed the D button to drive but it stayed in N. There was a green light around the N button indicating the selected button. I had to turn off the car, turn on the car two times before the car recognized I wanted to press the D button. The screen by the steering wheel had some sort of message but I don't recall what it said. …”
