The head lodged under the steering column, resulting in loss of consciousness and a severe traumatic brain injury (TBI) with ongoing neurological issues. Only the driverâs curtain and seat airbags deployed; the steering wheel and passenger frontal airbags did not.

This allowed forward momentum to propel the occupant, exacerbating injuries. Common issues in BMW i3 models include seatbelt twisting and retractor malfunctions, as reported in owner forums and repair services.

In this crashâs severity, proper function should have secured the occupant, preventing ejection and secondary impacts. Airbag Failure Analysis The BMW emp
