2009 BMW M3 Power Trainautomatic Transmission Problems

TO WHOM IT MAY CONCERN, I AM VERY HAPPY TO SEE YOUR ORGANIZATION TAKING AN INTEREST IN THIS ISSUE. IT IS A VERY DANGEROUS PROBLEM WITH THIS VEHICLE THAT BMWNA IS WELL AWARE OF, BUT INSISTS THAT IT IS "NORMAL BEHAVIOR" FOR MY CAR/TRANSMISSION. I BROUGHT THE CAR INTO THE DEALER, AND THEY WERE ABLE TO REPRODUCE IT, BUT THEY WERE TOLD BY BMW THAT THIS WAS "NORMAL BEHAVIOR." THE PROBLEM OCCURS WHEN YOU SLOW DOWN- LIKE FOR A TURN, BUT DO NOT COME TO A COMPLETE STOP. THE DCT TRANSMISSION SEEMS TO HAVE TROUBLE FIGURING OUT WHAT GEAR TO SELECT BECAUSE WHEN YOU STEP ON THE GAS TO ACCELERATE, THERE IS A VERY SIGNIFICANT DELAY IN THE ONSET OF POWER- UP TO 2-3 SECONDS. BY THIS TIME, THE DRIVER IS USUALLY REALLY DIGGING INTO THE THROTTLE. THE TRANSMISSION FINALLY PICKS A GEAR, WHICH RESULTS IN THE CAR SUDDENLY LURCHING...

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) DEAR [XXX], I AM VERY HAPPY TO SEE YOUR ORANIZATION TAKING AN INTEREST IN THIS ISSUE.

WITH THE DUAL CLUTCH AUTOMATIC TRANSMISSION IN D MODE, WHEN SLOWING FROM 50 OR 60 MPH TO 15-20 MPH THE TRANSMISSION WILL NOT DOWNSHIFT AND STAYS IN 6TH OR 7TH GEAR. EVEN WITH THE ACCELERATOR TO THE FLOOR THE CAR WILL NOT SELECT AN APPROPRIATE GEAR WHICH MAKES THE CAR BARELY ACCELERATE AT ALL CREATING A SAFETY HAZARD. THIS CAR HAS LITTLE TO NO TORQUE (BY DESIGN) AT VERY LOW RPMS, AND IT BASICALLY JUST SITS THERE AND DOESN'T MOVE. A DRIVER OFTEN SLOWS LIKE THIS WHEN MAKING A LEFT OR RIGHT HAND TURN AND HAVING THE CAR JUST SIT THERE UNDER THOSE CONDITIONS PRESENTS A HUGE SAFETY ISSUE IN TERMS OF BEING EITHER REAR-ENDED OR BEING HIT BY ONCOMING TRAFFIC. THE ENTIRE NATURE OF THE AUTOMATIC PROGRAM ON THIS CAR IS UNPREDICTABLE; IN SOME CASES IT WILL DOWNSHIFT, IN OTHERS (AS DESCRIBED ABOVE) IT WILL NOT, WHICH ADDS TO...

1. WHEN SLOWING DOWN FOR A RED LIGHT THAT TURNS GREEN, THEN TRYING TO ACCELERATE BEFORE ACTUALLY STOPPING, THE CAR HESITATES OR LAGS. COULD GET REAR-ENDED OR T-BONED IF TURNING IN AN INTERSECTION. SOMEONE IS GOING TO GET KILLED DUE TO THIS ONGOING, IGNORED, SERIOUS SAFETY FLAW. 2. CAN ROUTINELY REPRODUCE THIS HESITATION/LAG. 3. BMW REFUSES TO RESOLVE THE PROBLEM AND HAS TOLD IT'S DEALERS IT IS A NORMAL RESPONSE. *TR

2009 BMW M3 WITH DCT - ISSUE PRESENT FROM THE DATE OF PURCHASE. THE PROBLEM OCCURS FREQUENTLY WHEN IN AUTOMATIC MODE AND SLOWING SUCH AS AT AN INTERSECTION PRIOR TO A TURN AND THE TRANSMISSION SHIFTS INTO THE LOWER GEAR (USUALLY 2ND). WHEN THE ACCELERATOR IS PRESSED, THERE IS OFTEN NO RESPONSE FOR UP TO 2 SECONDS. WHEN THE VEHICLE DOES RESPOND, THE APPLICATION OF POWER MAY BE GRADUAL AND NOT DIRECTLY PROPORTIONAL TO THE ACCELERATOR PEDAL POSITION. ON SEVERAL OCCASIONS, THIS HAS RESULTED IN A NEAR-ACCIDENT SITUATION. WHEN MAKING A LEFT TURN WITH ONCOMING TRAFFIC, OR MERGING RIGHT WITH TRAFFIC THAT IS MAKING A LEFT TURN, I HAVE HAD TO TAKE EMERGENCY ACTION TO AVOID COLLISION. IT IS ONLY A MATTER OF TIME, UNTIL SOMEONE IS INJURED OR WORSE WHEN THE VEHICLE FAILS TO RESPOND AS EXPECTED. THERE ARE NUMEROUS COMPLAINTS OF THIS ISSUE IN THE NET DISCUSSION BOARDS,...

THE DUAL CLUTCH TRANSMISSION (DCT) IN MY CAR, A 2009 BMW M3 ROUTINELY HESITATES WHEN PUSHING THE ACCELERATOR IN 2ND GEAR. THE HESITATION IS LONG ENOUGH TO HAVE PUT ME AND MY PASSENGERS IN GRAVE DANGER. IN FACT, IT HAS ALMOST CAUSED A NUMBER OF ACCIDENTS WHEN MERGING WITH HIGHWAY TRAFFIC. THIS IS UNACCEPTABLE AND NEEDS TO BE IMMEDIATELY CORRECTED BEFORE SOMEONE IS SERIOUSLY INJURED OR KILLED. *TR

HELLO, I RECENTLY PURCHASED A 2009 BMW M3 WITH THE DCT TRANSMISSION. THE TRANSMISSION ACTS LIKE A SEQUENTIAL MANUAL SHIFTER, ALLOWING THE DRIVER TO SHIFT UP AND DOWN AT THEIR WILL. THESE SHIFTS HAPPEN INSTANTANEOUSLY, WITHIN FRACTIONS OF A SECOND. ADDITIONALLY, WHEN COMING TO A STOP, THE CAR WILL DOWNSHIFT TO 1ST GEAR ON ITS OWN, INSTEAD OF RELYING ON DRIVER INPUT, AS A MATTER OF CONVENIENCE. ALL OF THIS IS NORMAL, ADVERTISED, AND EXPECTED BEHAVIOR. THERE ARE TIMES, HOWEVER, WHEN THE CAR IS DECELERATING BUT NOT COMING TO A FULL STOP (WHEN TAKING A TURN AT AN INTERSECTION, FOR EXAMPLE), THAT THE TRANSMISSION WILL BEGIN ITS AUTOMATED DOWNSHIFTS BUT THEN BECOME INCREDIBLY UNRESPONSIVE. IN THESE CASES, IF I PRESS ON THE ACCELERATOR BEFORE COMING TO A FULL STOP, I'LL NOTICE A SIGNIFICANT LAG BEFORE THE ENGINE ACTUALLY REVS UP. BASICALLY, PRESSING ON THE GAS WON'T DO ANYTHING -- THE...

M-DCT TRANSMISSION LAG. WHEN YOU'RE TURNING AND CARS MAY BE COMING AT YOU THERE IS NO POWER, CAUSING SERIOUS ENDANGERMENT. *TR

THE PROBLEM OCCURS WHEN YOU SLOW DOWN- LIKE FOR A TURN, BUT DO NOT COME TO A COMPLETE STOP. THE DCT TRANSMISSION SEEMS TO HAVE TROUBLE FIGURING OUT WHAT GEAR TO SELECT BECAUSE WHEN YOU STEP ON THE GAS TO ACCELERATE, THERE IS A VERY SIGNIFICANT DELAY IN THE ONSET OF POWER- UP TO 2-3 SECONDS. BY THIS TIME, THE DRIVER IS USUALLY REALLY DIGGING INTO THE THROTTLE. THE TRANSMISSION FINALLY PICKS A GEAR, WHICH RESULTS IN THE CAR SUDDENLY LURCHING FORWARD, SOMETIMES INVOKING THE ANTI-SKID CONTROL. THE OCCURS FREQUENTLY. *TR

THIS COMPLAINT IS FOR A 2009 BMW M3 COUPE WITH THE DUAL-CLUTCH TRANSMISSION (DCT). I AM EXPERIENCING MAJOR SHIFT LAG TRYING TO REACCELERATE AFTER SLOWING DOWN. BASICALLY, THE 2ND GEAR WILL FAIL TO CATCH / ENGAGE WHEN I PUT MY FOOT ON THE GAS PEDAL CAUSING THE CAR STALL FOR A SECOND OR TWO. AFTER THAT, THE GEAR WILL ENGAGE ABRUPTLY AND I WILL BE PULLED VIOLENTLY FORWARD. THIS HAS RESULTED IN SEVERAL NEAR-ACCIDENT SITUATIONS: 1. I ALMOST REAR-ENDED SOMEONE WHEN THE GEAR ENGAGED ABRUPTLY WITH THE CAR JERKING FORWARD AT A STOP LIGHT WHEN IT TURNED GREEN AS I WAS APPROACHING, SLOWING DOWN TO 2ND GEAR. 2. I WAS ALMOST T-BONED AT A NON-REGULATED INTERSECTION. I WAS SLOWING DOWN WHEN APPROACHING THE INTERSECTION. THE CAR DOWNSHIFTED TO 2ND GEAR FOR ME AND ABOUT 1/4 WAY INTO THE INTERSECTION, I SAW A VEHICLE SPEEDING DOWN TOWARDS THE INTERSECTION ON MY...

2009 BMW M3 DCT (DUAL CLUTCH TRANSMISSION) EXHIBITS A SERIOUS LAG/HESITATION WHEN TRYING TO ACCELERATE FROM A RAPID ROLLING STOP. WHEN THIS ISSUE OCCURS IN AN INTERSECTION OR AT A STOP LIGHT, A SERIOUS SAFETY ISSUE EXISTS OF BEING T-BONED OR SLAMMED IN THE REAR. WHEN REPORTED TO BMW THEY CLAIM IT "WORKS AS DESIGNED". GUESS SOMEONE NEEDS TO BE SERIOUSLY INJURED OR KILLED BEFORE BMW WILL RESOLVE THIS ISSUE. *TR

SLOWING DOWN AT AN INTERSECTION TO MAKE A LEFT TURN. DECELERATED TO ABOUT 3 MPH. ACCELERATED TO INITIATE THE TURN. TRANSMISSION FAILED AND CAR DID NOT ACCELERATE. ABOUT 1.5-2 SECOND LAG TIME BEFORE THE TRANSMISSION ACTUALLY ENGAGED. ALMOST GOT HIT BY AN ONCOMING CAR. *TR

ON MY 2009 BMW M3 WITH DCT TRANSMISSION, THERE IS A NOTICEABLE LAG AFTER BRAKING WHEN YOU TRY TO ACCELERATE WHILE IN AUTOMATIC(D). THIS IS ESPECIALLY DANGEROUS WHEN TRYING TO PULL OUT OF AN INTERSECTION. THE CAR HAS NO POWER AND SITS THERE LIKE IT'S THINKING. SOMEONE IS GOING TO GET HURT. BMW NEEDS TO GET A FIX TO THIS SOFTWARE GLITCH. *TR

THE BMW M3 WITH DCT TRANSMISSION EXHIBITS A DANGEROUS ACCELERATION LAG IN SECOND GEAR. SPECIFICALLY, WHEN COASTING AT LOW SPEED IN SECOND GEAR, CLOSE TO ONE FULL SECOND WILL ELAPSE ONCE THE ACCELERATOR PEDAL IS DEPRESSED BEFORE THE TRANSMISSION ACTUALLY ENGAGES AND THE CAR BEGINS TO ACCELERATE. THIS MAKES MERGING INTO TRAFFIC, OR ANY SITUATION REQUIRING QUICK POWER APPLICATION, DIFFICULT AND POTENTIALLY DANGEROUS. *TR

MY 2009 BMW M3 WITH A DCT TRANSMISSION LAGS BETWEEN 1ST AND 2ND GEAR. WHEN YOU PUSH ON THE ACCELERATOR THE CAR DOES NOT GO FOR AT LEAST 2 SECONDS, THEN IT SHOOTS FORWARD. I HAVE COMPLAINED TO BMW BUT THEY SAY THIS IS NORMAL. THIS OCCURS ALL THE TIME WHEN I AM SLOWING DOWN AND THE CAR IS DOWN SHIFTING. *TR

SUMMARY: POWER APPLICATION LAG IN 2ND GEAR WITH M3 DUAL CLUTCH TRANSMISSION. SPECIFIC INCIDENT: WHILE ROLLING IN 2ND WITH ABOUT 1500RPM I WAS TRYING TO MERGE ONTO TRAFFIC FROM A MERGING RIGHT LANE THAT WAS ENDING SHORTLY. AFTER I THOUGHT IT WAS SAFE TO ACCELERATE, I DID SO, BUT THE ENGINE DID NOT PRODUCE POWER FOR THE NEXT 0.5 SECOND. AFTER POWER KICKED IN, IT WAS NO LONGER SAFE TO CONTINUE AS THE ONCOMING CAR WAS CLOSER THAN I HAD CALCULATED BEFORE ATTEMPTING TO ACCELERATE. ALSO, POWER KICKED IN AS I WOULD EXPECT IT TO HAPPEN 0.5 SECOND AGO. TO AVOID AN ACCIDENT, I HAD TO BREAK ABRUPTLY CAUSING THE BELTS TO LOCK AND MY WIFE CONSIDERABLE DISCOMFORT. GOOD THING NO ONE WAS BEHIND ME EXPECTING ME TO ACCELERATE. THE OCCURRENCE OF THE LAG IS PREVALENT WHERE THE SYSTEM IS NOT SURE WHETHER THE DRIVER WANTS TO BREAK OR ACCELERATE....

WHEN TRANSMISSION DOWNSHIFTS TO 2ND GEAR, SUDDEN AND COMPLETE LOSS OF POWER WHEN TURNING. HAPPENS WITH DCT TRANSMISSION WITH LATEST SOFTWARE. MANY SIMILAR COMPLAINTS ON BMW MESSAGE BOARDS, AND BMW IS BASICALLY IGNORING US. *TR

I OWN A 2009 BMW M3. IT HAS THE MDCT TRANSMISSION. THERE IS A DELAY WHEN COMING TO A ROLLING STOP AND THEN TRYING TO ACCELERATE AGAIN. THE DELAY OCCURS WHEN PUSHING THE ACCELERATOR AND WHEN THE ENGINE/TRANSMISSION ACTUALLY ENGAGES AND MOVES FORWARD. THE DELAY IS AS LONG AS 1-1.5 SECONDS. THIS HAS NEARLY CAUSED SEVERAL ACCIDENTS. BMW SAYS THIS IS NORMAL BEHAVIOR, BUT I DON'T BELIEVE IT TO BE THE CASE. IT SEEMS LIKE THE TRANSMISSION DOESN'T DOWNSHIFT AT LOWER SPEEDS. IN FACT, ONLY "THINKING" AND PROCEEDING TO DOWNSHIFT AFTER THE ACCELERATOR IS APPLIED. BY THEN, IT'S TOO LATE. AS A DRIVER, YOU EXPECT FORWARD MOMENTUM AS SOON AS THE ACCELERATOR IS APPLIED... NOT THAT IT DOWN SHIFTS AT THAT POINT. PLUS, THE READING DISPLAY SUGGESTS IT IS IN FACT DOWNSHIFTED TO 2ND GEAR... BUT I ASSURE YOU, THAT'S NOT THE POINT. THIS HAPPENS EVERY TIME THE SCENARIO IS...

THIS OCCURS REGULARLY, PERHAPS 10 TIMES PER WEEK OR MORE DEPENDING ON SEVERITY. ON DECELERATION, THE TRANSMISSION WILL DISENGAGE THE DRIVELINE. WHEN THE THROTTLE IS DEPRESSED AGAIN TO ACCELERATE, THERE IS A LONG DELAY (GREATER THAN 1 SECOND). THIS OCCURS AT SLOW SPEEDS (LESS THAN 20 MPH), FOR EXAMPLE WHEN ENTERING A LEFT TURN LANE WITH ONCOMING TRAFFIC. I HAD THIS BEHAVIOR DUPLICATED FOR A BMW TECHNICIAN WHO, UPON FURTHER RESEARCH, INDICATED THAT BMW WAS AWARE OF THIS ISSUE AND HAS DECLARED IT "NORMAL OPERATION". IT IS ONLY A MATTER OF TIME BEFORE A SERIOUS ACCIDENT IS CAUSED BY THIS ISSUE. *TR

MY 09 BMW M3 WITH DCT IS EXHIBITING GEAR SHIFTING SLOWNESS AND POWER LAGGING PROBLEMS AFTER HARD BRAKING. THE MOST RECENT INCIDENT WAS A NEAR REAR END COLLISION TODAY THAT REQUIRED ME TO BRAKE HARD FROM 70MPH, TO 40, SWITCH LANES AND ACCELERATE TO AVOID BEING HIT BY APPROACHING TRAFFIC FROM BEHIND. WHEN I ATTEMPTED TO ACCELERATE, THE CAR DID NOT RESPOND FOR WHAT SEEMED LIKE A COUPLE SECONDS. THE LAG WAS LONG ENOUGH THAT THE CAR BEHIND ME WAS FORCED TO LEAVE THE ROAD TO AVOID HITTING ME. *TR
