What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Blind spot warning randomly works. Passenger seatbelt phantom seatbelt warning while driving alone!
The vehicle was taken to the local service center who diagnosed that the front driver’s and passenger’s side air suspension was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer and dealer were both notified of the failure, but no assistance was offered.
Active Air Flap fault, Upper and Lower Actuator is not working and that is why engine is overheating. BMW has extended this warranty to 10 years/120K miles for 750 and 550 series manufactured up to Aug 2019. But they have not done that on 740 series.
This can cause restricted climate control in the vehicle interior, reduction of engine performance and possibly engine overheating. This appears to be a common problem with model years 2016+. I noticed this when I turned on the car and the check engine light came on. There is no visible damage to the shutter.
I got engine malfunction light on two separate occasions on my bmw; on each occasion the car was sent to dealership for repair to find that the upper and lower radiator blinds are at fault and this required replacement.
On two occasions a false fasten seat belt from passenger side has come up when the seat was not occupied. The car was sent for repair. On the first occasion it was indicated the wiring is loose for the seat belt harness so it was tightened.
