A FEW MONTHS AGO THE VEHICLE STARTED TO DISPLAY "DRIVE TRAIN MALFUNCTION" ON THE SCREEN WHILE SHAKING WITH A HORRIBLE ODOR OF FUEL. I TOOK THE VEHICLE IN TO THE DEALER AND WAS TOLD ALL OF THE FUEL INJECTORS NEEDED TO BE REPLACED! WE ARE TALKING ABOUT A $100K+ VEHICLE BARELY OUT OF WARRANTY. AFTER BATTLING WITH THE DEALER I WAS TOLD BMW HAS AGREED TO FIX THE PROBLEM UNDER WARRANTY. WHEN I WENT TO PICKUP THE CAR I WAS GIVEN AN INVOICE FOR ALMOST $500 FOR A DEDUCTIBLE! FAST FORWARD TO 06/06/2018, DRIVING IN HEAVY TRAFFIC AND AT A BUSY INTERSECTION I STARTED TO SMELL FUEL AGAIN AND I GOT A "FUEL SYSTEM MALFUNCTION" DISPLAYED ON THE SCREEN AND THE CAR DIED AND WOULD NOT START AGAIN. I HAD THE VEHICLE TOWED ONLY TO BE TOLD THAT NOW THE VEHICLE NEEDS AN IN TANK FUEL PUMP REPLACED! NOT A FEW MONTHS AFTER HAVING ALL THE FUEL INJECTORS REPAIRED. THE COST OF REPLACING THE FUEL PUMP OVER $1900 BUT WITH A DISCOUNT IT WOULD BE APPROXIMATELY $1550.00 (WHO KNOWS WHAT THE COST WILL BE WHEN I GO TO PICK IT UP). AFTER SOME RESEARCH, I FOUND OUT THAT THIS YEAR AND MODEL VEHICLE IS UNDER A RECALL FROM BMW FOR ALL THE SAME EXACT PROBLEMS AND SYMPTOMS I'M HAVING WITH THE FUEL PUMP. HOWEVER, THEY CLAIM THAT MY VIN IS NOT A PART OF THE RECALL AND THEY WILL NOT ASSIST IN ANY WAY. THIS IS A LOW MILLAGE CAR THAT IS WELL MAINTAINED AT ALL TIMES. I THINK ITS TIME BMW EXPANDED THE RECALL ON THE FUEL PUMP ISSUE FOR THIS VEHICLE AND CORRECTED THE PROBLEM THEIR DESIGN AND MANUFACTURING HAS CREATED BEFORE THEIR NEGLEGANCE COSTS SOMEONE THEIR LIFE WHEN THE VEHICLE STOPS ON THE HIGHWAY OR A BUSY INTERSECTION. IT'S TIME YOU DID THE RIGHT THING BMW NORTH AMERICA. I HAVE CONTACTED MY ATTORNEY AND WE WILL BE SENDING NOTICES TO OTHER BMW OWNERS WITH THE SAME PROBLEM TO JOIN A CLASS ACTION LAW SUIT. I CAN BE REACHED AT [XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

BMW 650 N63 ENGINE ISSUES AKA DRIVETRAIN MALFUNCTION (DTM) ERROR HAS BEEN A VERY COMMON ISSUE IN THESE CARS. IF YOU DO YOUR RESEARCH PEOPLE WITH BRAND NEW CARS WITH LESS THAN 100 MILES HAVE THESE ISSUES AS WELL. LONG STORY SHORT BMW, NA OFFERED TO BUY BACK MY CAR AFTER SPENDING MORE THAN 5 WEEKS IN THE SHOP FOR 2ND REPAIR. FIRST REPAIR WAS THE RECALL , BMW OFFERED AS THE "CUSTOMER CARE PACKAGE" . I PURCHASED IT CPO (CERTIFIED PRE-OWNED) W/ 26,000 MILES., I WAS UNHAPPY WITH THE OFFER SINCE THEY DEDUCTED MILEAGE USED. DTM OCCURRED AT APPROXIMATELY 29,000 MILES AFTER HAVING THE CAR FOR LESS THAN 4 MONTHS. OF COURSE THE BMW DISMISSED IT SINCE THE DTM RESOLVED AFTER RESTARTING THE CAR. IT USUALLY OCCURS RANDOMLY WHILE DRIVING HIGH SPEEDS ABOVE 60 MPH ON THE FREEWAY THE CAR SHAKES, RATTLES, DECELERATES AND IS UNRESPONSIVE WHEN STEPPING ON THE GAS. THIS IS A KNOWN ISSUE IN NEW 650I W/ N63 ENGINES PLEASE CHECK YOUTUBE, BMW FORUMS AND CLASS ACTION LAWSUITS FILED 9/2015 AGAINS BMW, NA. THE VEHICLE WAS GETTING ALL THE PARTS REPLACE FOR THE ENTIRE MONTH. THE CAR WAS FINE FOR 2 MONTHS THAN IT OCCURRED AGAIN AND SINCE THEY DID NOT WANT TO EXTEND MY WARRANTY I DECIDED TO REQUEST A BUY BACK. OTHER ISSUES: EXCESSIVE ENGINE OIL BURNING, BACK PASSENGER WINDOWS NOT ROLLING UP COMPLETELY REAR WHEAL CRACKING. DTM STILL OCCURRED AFTER THESE PARTS WERE REPLACED IN THE CAR FOR THE 2ND REPAIR: -CATALYTIC CONVERTOR (SINCE THEY DISCOVERED BOTH CATALYTIC CONVERTERS WHERE COMING APART), ALL 8 SPARK PLUGS , 32 VALVE GUIDE SEALS. I HOPE THIS WAS OF USE FOR SOMEONE WHO FEELS HELPLESS AND HAVE TO SETTLE WHATEVER BMW, NA IS OFFERING. STILL ENTERTAINING THE THOUGHT OF FILING A SEPARATE CLAIM FROM THE "BUY BACK" OFFERED BY BMW. THIS IS A HUGE SAFETY ISSUE WHICH MAY LEAD TO A FATALITY DUE SUDDEN DECELERATION WHEN DRIVING IN HIGH SPEEDS.

1EA21002 · Desiccated Air Bag Inflator Rupture
Opened Sep 17, 2021 · No close date supplied
Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
