Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Was driving down a 2 lane road at about 55 MPH, and a warning light message appeared on the dash and said battery no longer charging then another message that said coolant overheating vehicle shutting down appeared. And the car would no longer accelerate. So I had to pull over on a busy 2 lane road and turn off my car and turn it back on, and then the car was working normally again. This could have been very bad if it was on a multi-lane highway. My safety was put at risk. …”
