Air bags

61 reports4 crashes1 fire
“FRONT PASSENGER SEAT OCCUPANCY DETECTION MAT HAD TO BE REPLACED AS IT WAS DEFECTIVE. THOUGH NOT IN PREVIOUS RECALLS IN SIMILAR BMWS AND SIMILAR YEARS, THE ERROR PRESENTED A SAFETY ISSUE THAT WOULD DISABLE THE FRONT PASSENGER AIR BAGS AND INCREASE THE RISK OF INJURY DURING A CRASH. WITH THIS ERROR, I WAS FORCED TO REPAIR THE SEAT MAT AND EXPENDED $1.5K TO REMEDY THIS SAFETY ISSUE. THIS SEAT MAT ISSUE IS A KNOWN BMW PROBLEM THAT BMW AND NHTSA HAVE NOT ADDRESSED. VIN: [XXX]. *TR”

Electrical system

22 reports1 crash1 fire1 related recall
“The contact owns a 2006 BMW M5. The contact stated that while opening the trunk of the vehicle, the positive terminal on the battery was fully melted and was very hot. The contact believed that the issue was a fire hazard and was lucky to have found the issue before any other damage could occur. The contact referenced NHTSA Campaign Number: 12V126000 (Electrical System) as a possible cause for the failure. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure and stated that the vehicle was inspected in 2012 under the recall but had passed the inspection, and the vehicle was not repaired. The failure mileage was 97,000.”

Power train

13 reports1 crash
“THE EARLY M5 WITH THE SMG (SEQUENTIAL MANUAL GEARBOX) 7 SPEED HAVE NUMEROUS TSB'S AND WARRANTY CAMPAIGNS. THE SHIFTING OF THE GEARBOX IS UP EXECUTED BY PRESSURE FROM THE HYDRUALIC PUMP THAT STORES AAPRX 80PSI IN THE ACCUMULATER. THIS ACCUMULATOR OR PUMP HAS A HI CHANCE OF FAILING AND WHEN IT DOES THE CAR SHUTS DOWN WITHOUT WARNING. MY CAR SHUT DOWN IN THE MIDDLE OF THE INTERSECTION JUST RECENTLY. AND I HAVE HAD THIS PUMP REPLACE TWICE OUT OF WARRANTY AND ONCE WITHIN WARRANTY. A MAJOR FLAW OF THE GETRAG SMG 7SPD. BMW DISCONTINUED THIS TRANSMISSION BUT CONTINUES TO RAISE PRICES ON THE REPLACEMENT PUMPS AS THEY KNOW THERE IS A HIGH TURNOVER OF REPAIRS. PLEASE VISIT THE BMW M FORUMS AS THIS TOPIC IS HEAVILY DISCUSSED”

“CLEARANCE FAILURE ON S85 ENGINE TO ROD BEARINGS CAUSES OIL STARVATION. THIS IN TURN CAUSES ENGINE CATASTROPHIC FAILURE. IF DRIVING THIS WILL EFFECT POWER BREAKING, POWER STEERING AND ALL COMPONENTS REQUIRING THE ENGINE TO BE RUNNING. THIS IS A VERY COMMON ISSUE, I NOW HAVE SYMPTOMS REQUIRING A CHANGE OF ROD BEARINGS. *TR”

“WELL DOCUMENTED (ON THE INTERNET) PROBLEM WITH THE PASSENGER SIDE ACTIVE RESTRAINT SYSTEM FAILING, TYPICALLY DUE TO THE PASSENGER SIDE OCCUPANCY MAT. THIS PROBLEM HAS BEEN DOCUMENTED IN ALMOST EVERY MODEL MANUFACTURED SINCE 2000, BUT HAS ONLY BEEN ADDRESSED IN A FEW, SELECT, VEHICLES. THIS IS THE MOST COMMON COMPLAINT FOR THIS MODEL ON CARSAFETY.GOV AND HAS NOT BEEN ACKNOWLEDGED BY BMW OF NORTH AMERICA. THIS PROBLEM, IN ITSELF, CAN LEAD TO A VARIETY OF MALFUNCTIONS IN THE EVENT OF AN ACCIDENT CAUSING SERIOUS INJURY OR DEATH. THE PROBLEM HAS ALSO LED TO A LARGE MARKET OF "DUMMY SENSORS" BEING SOLD ON EBAY AND SIMILAR SITES, WHICH TRICK THE COMPUTER INTO THINKING THE AIRBAG SENSOR IS CORRECTLY FUNCTIONING. THESE DUMMY SENSORS DO NOT REMEDY THE PROBLEM AND CAN LEAD TO AN INCREASED RISK OF INJURY OR DEATH. SYNOPSIS: AIRBAG SYSTEM WARNING LIGHT AND RESTRAINT SYSTEM WARNING LIGHT APPEAR IN INSTRUMENT CLUSTER. IDRIVE SYSTEM READS: PASSENGER RESTRAINT SYSTEM MALFUNCTION. SEAT SENSOR MAT FOR THE PASSENGER SEAT AIR BAG DISENGAGES WHEN PASSENGER IS SEATED. THE DISENGAGING OF THE PASSENGER AIR BAG POSES A GREAT DANGER FOR THE PASSENGER DUE TO THE PASSENGER AIR BAG WILL NOT…”
