Example complaints

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

“Sitting at a stop light and car lost all power. No ability to turn on hazard lights or call for help or anything. In my opinion this is a huge safety issue since my wife could have been rear ended since there were no lights at all on the car and no way to turn on any warning lights. Thank goodness this happened when stopped and not moving. I could not imagine the outcome of losing power at speed when everything is electronically controlled.”
