Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving my lease vehicle on two separate days, it completely shut down while in motion with no prior warning. The first incident occurred while crossing a MAX train intersection in downtown Portland. The engine stopped mid intersection, emitted a strong mechanical odor, ticking noises began, and dashboard alerts appeared. I could not restart or shift the vehicle into neutral. It was stuck, blocking the intersection. Although hazard lights were flashing, the vehicle appeared completely undamaged, so other drivers didn’t realize it was disabled. …”
