Example complaints

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

“My driver side seatbelt sensor suddenly would randomly detect no seatbelt despite being buckled and then the steering wheel airbag deployed into me while I was reversing the car under 2mph. I suffered burns and bruises, hearing loss, and disorientation from the deployed airbag. I could have broke my nose, or my wrist or fingers. BMW dealership refused covering towing and inspection. BMW airbags across multiple models and years have experienced recalls and issues. Seatbelt detection sensor blinked before airbag deployed into me.”
