Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

MY VEHICLE IS A LOW MILEAGE (36K) WELL MAINTAINED CAR. MY LOCAL DEALER REPLACED THE DRIVER AIR BAG UNDER A RECALL JUNE 29, 2020. SHORTLY AFTER WITHIN 250 MILES/2 MONTHS A SRS/AIR BAG SYSTEM FAULT/WARNING STARTED HAPPENING. IT WAS DIAGNOSED AS A FAULTY PASS OCCUPANCY SENSOR THAT THEY WANT $3600 TO REPLACE. UNFAIR, THERE HAVE BEEN SEVERAL PASS OCCUPANCY SENSOR RECALLS FOR OTHER MODELS OF THE SAME VINTAGE (2006-2008). THIS SHOULD BE COVERED UNDER THE 15 YR EXTENDED LIMITED WARRANTY OFFERED TO OTHER BMW MODEL OWNERS.

THE PLASTIC INSULATION ON THE HEADLIGHT WIRING HAS FLAKED OFF LEAVING THE WIRES COMPLETELY BARE IN SOME PLACES. THIS HAS RESULTED IN THE LOSS OF A DRL, HEADLIGHT BALLAST, AND ADAPTIVE HEADLIGHT MOTOR. THIS IS A WELL DOCUMENTED ISSUE ONLINE, FROM BMW OWNERS OF MULTIPLE YEARS/SERIES. IN FACT, THERE IS ALREADY AN NHTSA COMPLAINT ON THE EXACT SAME YEAR AND MODEL AS I HAVE. THIS ISSUE IS DANGEROUS IN MULTIPLE WAYS. THE LOSS OF LIGHTING AT NIGHT COULD RESULT IN AN ACCIDENT, HARMING BOTH THE OCCUPANTS AND PEOPLE NEARBY. THE HIGHLY CHARGED BARE WIRING COULD SHORT, SPARK, AND CAUSE A FIRE. THE CONTINUED DESTRUCTION OF HEADLIGHT BULBS, MOTORS, ETC IS HARMFUL TO THE CONSUMERS AND ECONOMY AS THOSE PARTS CAN BE VERY EXPENSIVE.

report

From owner reports, verbatim

When the car was in a local Tire Discounters for an unrelated repair the mechanics noted that the rear subframe had significant degradation and the car was unsafe to operate without immediate replacement of the entire subfrane - at a cost of roughly $5,000. I know there have been subframe recalls of BMWs in the past. While this vehicle was not part of those recalls its obviously been an area of concern with this auto maker.
