Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving at interstate highway speed at approximately 70 mph in heavy rush hour traffic, the vehicle suddenly made a popping sound and immediately lost all engine power. The accelerator became unresponsive, and the vehicle rapidly decelerated without warning. I was forced to coast across lanes to the shoulder to avoid a collision. The engine shut down completely and the vehicle would not restart. This created a serious risk of injury or death due to loss of power in high-speed traffic. The vehicle had to be towed and is currently undrivable. …”
