NHTSA Complaint #11613048 — 2023 TOYOTA MIRAI

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. There were no warnings, messages, or other problems prior to my husband’s death. He was not informed of the auto shut off feature at the dealership at the time of purchase and the dashboard warning never once appeared to alert him such a feature existed. He thought it was safe to sleep in his running car. The auto shut off feature does not work properly as there was no warning on the dashboard and does not safeguard against people or animals being in the car at the one hour mark. Toyota needs to know this is a deadly feature and make some serious changes.
