From owner reports, verbatim
MY CAR SUDDENLY LOST ACCELERATION WHILE I WAS DRIVING ON A FREEWAY THEN THE ENGINE DIED.
CARS' IDLE HAS BEEN FLUCTUATING FOR A COUPLE OF WEEKS AT IDLE. VEHICLES FUEL PUMP HAS BEEN REPLACED 2 TIMES ALREADY THROUGH OUT IT'S LIFE. LAST WEEK (JULY 13,2017) CAR DIED IN THE MIDDLE OF THE ROAD AND I HAD TOWED INTO THE DEALERSHIP THAT SAME MORNING. DEALER REFUSES TO TAKE ANY INITIATIVE TO FIX THE PROBLEM AT ALL. I HAVE SOFTWARE WHERE IT SHOWS THAT THE CARS VEHICLES HIGH PRESSURE FUEL PUMP IS FAILING. CAR IS THROWING CODES TOO. CAR WAS IN MOTION WHEN FUEL PUMP DIED ON ME IN A CITY STREET.
Airbags

From owner reports, verbatim
The contact owns a 2008 BMW 135I. The contact stated while starting the vehicle, the air bag warning light was illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the passenger occupancy sensor mat to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 17V428000 (Air Bags) however, the VIN was not included. The manufacturer had not been informed of the failure. The failure mileage was 39,850.
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.

BMW SEATTLE DECLINED TO COVER THE TIRE BY WARRANTY STATING THAT I BOUGHT IN 2009 AND IT IS ABOVE 5 YEARS SO NO WARRANTY ON IT, I HAD TO BUY THE AFTER MARKET SET OF RIMS (VMR MODEL 701) THAT DOES NOT FIT TOTALLY WITH THE CAR AND WOULD LIKE TO REVERT TO USE THE ORIGINAL SET WITH A REPLACED REAR RIGHT RIM. I TOOK PICTURES AND SENT IN 2 DAYS AGO TO BMW AS THE SET OF RIMS I BOUGHT FOR THE CAR DO NOT REALLY FIT. THE ORIGINAL CRACKED RIM HAS A MANUFACTURING DEFECT AS SHOWN IN MY PHOTOS TAKEN FROM INSIDE THE RIM LOOKING OUT: THE ALUMINUM MATERIAL SHOW A RIDDLE IRREGULARITY AT SEVERAL PLACES. BMW CALLS ME TODAY TO RE-ITERATE THE REFUSAL FOR THE RIM REPLACEMENT.

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.

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.
