Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I was stopped at a stop light with my foot on the brake for about a minute when the car suddenly accelerated and lunged forward.I applied more pressure to the brake,all the way to the floor , but the car would not stop. The car in front of me is the only thing that stopped the car ,as he was stopped too. The car then bounced backward and turned off by itself. I was on a main street at a light. It was fortunate that another car was stopped in front of me because it stopped the car and prevented my car from hitting pedestrians.”

“On 09/16/25, I was exiting the Florida turnpike onto Sawgrass Highway via the exit ramp on exit 71. As I decelerated from 60 MPH to 35 MPH to match the speed of the exit ramp, I was in the left most lane in the two-lane exit ramp. My car spun out and I lost control of the vehicle, which caused the vehicle to spin through the two lanes of the ramp several times and ended up drifting onto the edge of the retention pond on the left of the exit ramp. …”
