Example complaints

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

“UNKNOWN My car started stalling when it comes to a full stop. I.e. if I stop at a red light or stop sign, and I then press the gas, it stalls. It might inch forward, but it doesn’t really accelerate. This happened last year, and I took it to the dealer. They couldn’t reproduce the results, and they could only suggest changing my small 12V battery. Today, it stalled 8 times, between 2 short drives. Each at a stop sign only travelling ~5 miles total. I have an appointment at the dealer but this is exactly what happened last year with no diagnosis. No check engine light is on or anything.”

NHTSA complaint #11470356, filed 2022-06

“Stopped at red light, then the car didn't accelerate when hitting gas. Engine revs but the car does not accelerate. It happened multiple time when the car was out in sun with full ac on(100f). Happened once in intersection and almost got hit head on”
