Apr 22, 2024Engine My grill shutters are faulty and the problem has been persistent and the vehicle is only at 30,000 miles. This is the same part that was issued an extended service contract by BMW for various other models. I believe my model is rare enough to not be included but it should. The existing recall/warranty is âSIB 01 12 19 FRONT GRILLE UPPER/LOWER ACTIVE AIR FLAPS: LTD WTY EXT TO 15 YEARS/150,000 MILESâ and I believe mine should be included in this as it is the same engine as these various models. The grill shutters are experiencing the same fault and they do not open and close properly as the models listed. I receive code P05AF which is signals the lower shutters are not closing.
Sep 4, 2021 · crashAir bags The automatic emergency did not engage the brakes as described to by the dealer, BMW genius and the BMW website. The car was in a collision at low speed (under 35mph) with the car in front of me which put me at risk. BMW sent an engineer from N.J. to inspect the car. The is under warranty and it was in perfect working order. The engineer determined that the system did not engage because the accelerator was depressed, I was told that the system does not work when the accelerator is depressed but that is not how the system is advertised and it is not how it was described in ALL of the BMW marketing materials.
