What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Dt: the contact stated the brakes failed while driving . The pedal went to the floor, resulting in an accident. The vehicle went over the curb and hit a parking pillar. The undercarriage was damaged. The contact reports hearing squeaking noises coming from the brakes two weeks prior to the incident.
The contact stated the air bag light flashed on the dashboard indicating the passenger side air bag was not working. The contact did not take the vehicle to the dealer. The contact stated if the vehicle is involved in a crash the passenger side air bag would not deploy and could cause a severe injury.
The contact stated that when driving at various speeds, the air bag warning light would intermittently illuminate. The vehicle was inspected by the dealer who informed the contact that the front passenger air bag sensor had failed. The vehicle was repaired. The vin was not available.
Passenger airbag lamp is on and stays on after technician at the bmw service center reset the vehicle's computer (cleared faults). Vehicle did not get into situation which would trigger airbag deployment, but potentially the passenger frontal airbag may malfunction and render the passenger airbag inoperative.
It has been 18 months and the on board computer has problems with the entertainment, and bluetooth. The computer continues to play cd's after the engine is shut off. The dealer ignored the problem for months until I said the car would need to be bought under the "lemon law'.
My bmw 745i has been in the shop repeatedly to fix a problem with the gas reading mechanism. The car tells me there is gas when there is none or vice versa. Twice the car has completely stopped working having to be towed. The most recent time was this morning while driving on the highway the car just stopped.
