Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The warning that is supposed to appear every time the car is started that the car will auto shut off after one hour of idling never once appeared. As a result, my husband did not know the auto shut off feature existed on his car. He fell asleep in his car on a hot summer day and when the car auto shut off after an hour, he died of heatstroke. The lack of a warning coupled with the car auto shutting off after an hour was reproduced and confirmed by an independent service center. The car has not been inspected by anyone else. …”
