Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The car is currently not safe to drive. On june 25th I drove the car for 40 minutes on the highway. When I exited the highway, the engine would race when I came to a stop light. The brakes were applied and the car was at a complete stop, but the engine would race so that the speedometer registered 50 miles per hours. When I released the brakes to proceed through the light, the car immediately sped off at nearly fifty miles per hour. I did not apply the gas pedal at all. I had no control over the car. It was not shifting into lower gear. It was racing, even when the car was put into park. …”
