Example complaints

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

“Seats are not registering for air bag and the middle back seat belt alarm goes off saying to put seat belt on, but no one is sitting in back seat. So while I'm driving I have to pull over and plug seat belt in to get the seatbelt warning sound to stop. The seatbelt is not registering in the back seat and the front seat is not registering someone is sitting there for the airbag. It doesn't register my grandson or my son, which is dangerous. Kids are involved.”

NHTSA complaint #11626075, filed 2024-11
