THIS IS A PROBLEM WITH THE M-DCT AUTOMATED MANUAL TRANSMISSION IN THE E92 BMW M3. IT IS A RECURRING ISSUE AND IS A SAFETY ISSUE AS WELL. WHEN TRAVELING AT LOW SPEEDS, SAY WHEN COASTING AND WHEN THE TRANSMISSION IS IN IT'S D MODE (AUTOMATIC LIKE MODE), WHEN YOU QUICKLY TRANSITION FROM LIGHT BRAKING TO MEDIUM THROTTLE APPLICATION THE VEHICLE BECOMES COMPLETELY UNRESPONSIVE TO THE GAS PEDAL INPUT AND OFFERS NO ACCELERATION. AFTER A DELAY OF A SECOND OR SO THE CAR WILL REV A BIT, SLIP THE CLUTCH AND ACCELERATE STRONGLY. THIS OCCURRENCE IS NOT UNIVERSAL BUT IS COMMON. ANY TIME YOU MAKE SUCH A TRANSITION AND REQUIRE THE VEHICLE TO "OBEY" AND ACCELERATE AS PER YOUR USE OF THE GAS PEDAL THE VEHICLES MARKED LACK OF ACCELERATION CAN BE A SAFETY ISSUE. SUCH OBVIOUS CASES INCLUDE LANE CHANGES, INTERSECTIONS WITH A YIELD OR MERGING INTO TRAFFIC AFTER A TURN. THIS ISSUE IS WIDESPREAD ON INTERNET MESSAGE BOARDS FOR OWNERS OF THIS CAR. *TR

I HAVE NOTICED SINCE THE SAFETY RECALL ON THE M-DCT GEARBOX: THERE IS A SIGNIFICANT LAG OR HESITATION OF AT LEAST 2 SECOND BETWEEN APPLYING PRESSURE TO THE ACCELERATOR AND THE CLUTCH ENGAGING AND GIVING ACCELERATION TO THE WHEELS. THIS RESULTS IN A COMPLETE LOSS OF POWER AND CAUSES THE CAR TO JUST "COAST". THIS DOES NOT HAPPEN FROM A STAND-STILL, BUT OCCURS PRIMARILY WHEN THE CAR IS IN MOTION AT VIRTUALLY ALL RANGES OF SPEED, FROM ROLLING STOP THROUGH STANDARD ROAD SPEEDS OF ANY DEGREE . THE PROBLEM IS ACUTE IN "D" MODE, BUT OCCURS IN "S" MODE AS WELL IN 2ND GEAR. THE RESULT OF THIS IS THAT YOU CAN PULL OUT INTO TRAFFIC AND RATHER THAN INCREASE YOUR ACCELERATION NORMALLY, THE CAR WILL JUST COAST WITH NO POWER. THIS IS EXTREMELY DANGEROUS AND I HAVE HAD SEVERAL NEAR MISSES WITH A CHANCE OF A CAR REAR ENDING ME BECAUSE THE GEARBOX IS FUNCTIONING LIKE THIS. *TR

THERE IS AN ISSUE WITH THE M-DCT TRANSMISSION EQUIPPED ON MY VEHICLE. THE PROBLEM OCCURS WHEN THE CAR IS BROUGHT TO A NEAR STOP SUCH AS AT AN INTERSECTION, AND THEN PRESSURE IS APPLIED TO THE ACCELERATOR TO TRY AND PULL AWAY QUICKLY. IN THIS CASE THE VEHICLE WILL HESITATE FOR A LONG PERIOD OF TIME, POTENTIALLY LEAVING THE CAR UNRESPONSIVE FOR A FEW SECONDS WHILE COASTING SLOWLY INTO THE INTERSECTION WITH ONCOMING TRAFFIC BEARING DOWN. THE MANUFACTURER CLAIMS THIS BEHAVIOR IS NORMAL FOR THE TRANSMISSION BUT IT IS CERTAINLY NOT SAFE. ADDITIONALLY, THE PROBLEM WAS EXACERBATED BY A PRIOR SOFTWARE UPDATE WHOSE INTENTION WAS TO FIX OTHER PROBLEMATIC BEHAVIORS OF THE TRANSMISSION. SO THE BEHAVIOR IS CLEARLY NOT GERMANE TO THE TRANSMISSION ITSELF, IT IS INSTEAD THE RESULT OF GLITCHY SOFTWARE WHICH THE MANUFACTURER SHOULD RIGHTLY BE OBLIGATED TO FIX. I FIRMLY BELIEVE THAT THIS PROBLEM COULD ENDANGER THE LIVES OF THE OCCUPANTS OF MY VEHICLE AND SINCERELY HOPE IT CAN BE RECTIFIED IMMEDIATELY. *TR

I HAVE A BMW M3 WITH THE DCT TRANSMISSION. SINCE GETTING A SOFTWARE UPDATE TO FIX ANOTHER NHTSA ISSUE WITH THE TRANSMISSION, MY CAR WILL HAVE NO POWER AT ALL FOR A COUPLE SECONDS WHEN I SLOW DOWN TO AROUND 10MPH, AND THEN TRY TO ACCELERATE AGAIN. THIS LEADS TO A VERY DANGEROUS SITUATION WHEN CARS ARE COMING AT ME AND THE CAR DOES NOT MOVE. THIS OCCURS MAINLY WHEN THE DCT IS SET TO THE AUTOMATIC MODE. MANY OTHERS HAVE HAD THE SAME ISSUE. THIS OCCURS PRETTY MUCH EVERY TIME I SLOW DOWN TO AROUND 10-15MPH FROM 40MPH OR MORE. MANY PEOPLE HAVE TOLD THE DEALER AND WERE TOLD THIS IS NORMAL!! BMW IS AWARE OF THIS AND TOLD THE DEALERS IT'S NORMAL. MANY MORE COMPLAINTS CAN BE FOUND ON WWW.M3POST.COM/FORUMS. *TR

DURING A ROLLING STOP SITUATION WHICH IS FOLLOWED BY ANY ACCELERATION (SUCH AS A LEFT OR RIGHT HAND TURN), THERE IS A THROTTLE DELAY AND THE VEHICLE HAS THE FEELING OF AN "ENGINE STALL" AND LOSSES ALL POWER FOR 1-2 SECONDS WHILE IT SEARCHES FOR A GEAR. THE PROBLEM IS CONSISTENT AND CAN BE RECREATED AT ANYTIME. THE PROBLEM PRESENTS A SAFETY HAZARD IN TRAFFIC SITUATIONS BECAUSE YOU ARE UNABLE TO MOVE OUT OF THE WAY OF ONCOMING VEHICLES. THERE ARE MULTIPLE COMPLAINTS FROM OWNERS ON THE INTERNET AND CONFIRMED AT THE DEALERSHIP. THE MANUFACTURER CLAIMS IT IS NORMAL OPERATION FOR THE TRANSMISSION. (TECHNICAL SERVICE BULLETIN SB SI B 28 07 08) HOWEVER, MANY PEOPLE DID NOT EXPERIENCE THE PROBLEM UNTIL AFTER THEIR VEHICLE UNDERWENT A RECENT RECALL FOR TRANSMISSION SOFTWARE UPDATES.

ON SATURDAY, JULY 26TH, I DROVE A SHORT DISTANCE FROM MY HOME (AFTER A LONG CRANKING START) AND THE CAR SEEMED DRIVE NORMALLY UNTIL I TURNED TO ENTER A SHOPPING CENTER(FORTUNATELY, A SHORT DISTANCE FROM MY HOME, AS IT TURNS OUT). WHILE DRIVING INTO THE SHOPPING CENTER ENTRANCE (10 OR 15 MILES PER HOUR) I FELT A JOLT AND THE CAR SLOWED DRAMATICALLY. I CHECKED THE REARVIEW MIRROR TO SEE IF I HAD BEEN HIT BY ANOTHER CAR, BUT HAD NOT. I THEN REALIZED THAT THE ENGINE WAS NOT RUNNING, PUT IN THE CLUTCH AND COASTED TO A STOP AT A STOP SIGN. I ATTEMPTED TO RE-START THE CAR BUT WAS UNABLE TO. THE ENGINE 'TURNED OVER' BUT WOULD NOT START. THERE WERE NO WARNING LIGHTS OR MESSAGES BEFORE OR AFTER THE FAILURE OR AT ANY OTHER TIME. AT THIS POINT, I USED BMW ASSIST TO GET HELP SINCE I WAS PARTIALLY BLOCKING A BUSY INTERSECTION WITHIN THE SHOPPING CENTER. A TOW TRUCK ARRIVED ABOUT 45 MINUTES AFTER MY CALL TO BMW ASSIST. WHEN THE TOW TRUCK ARRIVED, THE DRIVER POINTED OUT A LEAK AND PUDDLE/STAIN ON THE ASPHALT COMING FROM THE FRONT OF THE CAR. THE STAIN WAS ABOUT 2 BY 3 FEET. THERE WAS ALSO A SMELL OF GASOLINE. WHEN THE CAR WAS TOWED TO THE DEALERSHIP, THE SERVICE ADVISOR ALSO NOTICED GAS STILL LEAKING FROM THE FRONT OF THE CAR AND DRIPPING ON THE GROUND. A LOANER CAR AND I WAS ON MY WAY. ON MONDAY, JULY 28TH I CALLED THE SA TO CHECK THE STATUS OF THE CAR AT ABOUT 3:00 PM. I WAS TOLD THAT THE HIGH PRESSURE FUEL PUMP AND A CONNECTING HOSE NEEDED TO BE REPLACED. HE SAID THE PARTS WERE ORDERED AND SHOULD BE ON HAND BY WEDNESDAY, JULY 30 TO BE INSTALLED. I ASKED ABOUT THE HOSE, AND THE RESULTING GASOLINE LEAK AND HE COMMENTED ABOUT THE LARGE AMOUNT OF GAS THAT HAD BEEN SPRAYED OUT IN THE ENGINE COMPARTMENT DUE TO THE FAILURE OF THE HOSE. THERE EASILY COULD HAVE BEEN A CATASTROPHIC FIRE DUE TO THE MAGNITUDE OF THE GASOLINE LEAK. THE DEALERSHIP WILL REPAIR THE PUMP AND HOSE UNDER WARRANTY. THE CAR IS A BMW 335I. *TR

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.

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.
