2004 BMW 5 Series Powertrain & Transmission Problems

I WAS DRIVING ON MY WAY TO WORK AND STARTED SMELLING SOMETHING BURNING. ALL ELECTRICAL WARNING LIGHTS STARTED LIGHTING UP THE DASH AND THEN DISPLAYS GO BLANK. PASSENGER COMPARTMENT WAS FILLING UP WITH SMOKE COMING FROM UNDER GLOVE BOX. I PULLED OVER AND CALLED FIRE DEPARTMENT. WE DISCONNECTED BATTERY AND TOOK TO BMW. THEY SAID MICRO-PROCESSOR LOCATED IN SPARE TIRE STORAGE AREA HAD SHORTED OUT DUE TO WATER. I DON'T CARRY COOLERS AND DON'T LEAVE MY TRUNK OPEN WHEN IT RAINS. HOW DID WATER GET THERE. BULLETINS SHOW THAT SUNROOF DRAINS GET CLOGGED AND WATER GETS INTO TRUNK AND SHORTS OUT ELECTRICAL. SERVICE BULLETIN SAYS IF THIS HAPPENS, CUSTOMER PAY BUT MOVE ELECTRICAL TO WHERE IT CAN'T GET WET. SO BMW KNOWS IT'S A PROBLEM AND CAN CAUSE A FIRE BUT DOESN'T CARE TO COVER REPAIR. NOW I'M STUCK WITH $1000 REPAIR FOR MICRO-PROCESSOR JUST TO BE ABLE TO TELL WHAT ELSE IS BURNED UP. I HAVE TO PAY BEFORE I WILL KNOW IF IT WILL COST AN ADDITIONAL $5,000 TO REPAIR. I'M LUCKY ELECTRICAL DIDN'T CATCH FIRE AND BURN UP ENTIRE CAR. *TR

TRANSMISSION GOES INTO A LIMB MODE WHEN REACHING 30-40 MPH OF SLOWING DOWN FROM OVER 60 MPH AND A BANG HAPPENS LIKE IT YOU GET HIT FROM BEHIND THE CAR WOULD NOT SWITCH GEAR AND THE ENGINE WOULD INCREASE THE RPM THE CAR TOP SPEED WOULD BE 40 MPH WHEN IT MALFUNCTIONS THIS WOULD HAPPEN IN CITY STREETS AND HIGHWAYS THE CAR RESETS BY TURNING THE ENGINE OF WAITING A WHILE AND RESTARTING THE ENGINE

THIS TRANSMISSION IS SLIPPING AGGRESSIVELY. IT HAPPENS ON UP-SHIFT 1-2 AND DOWNSHIFT 2-1. IT HAPPENS LIKE 4 TO 5 TIMES IN A WEEK. ALSO SOMETIMES I GET A BIG SLAM ON BOTH UP-SHIFT AND DOWNSHIFT... WHEN THIS HAPPENS, THE TRANSMISSION MALFUNCTION ERROR MESSAGE POPS UP AND REDUCES MY MOVEMENT TO SAFE-MODE, UNLESS I SHUT THE ENGINE OFF AND RESTART THE ENGINE. IF YOU TAKE TIME TO GO ON BMW FORUMS AND BLOGS, EVERYONE COMPLAIN ABOUT THIS ISSUE WITH THIS 5 SERIES... PLEASE DO SOMETHING.. THE PASSENGER AIRBAG RESTRAINT ERROR POPS UP EVEN WHEN SOMEONE IS NOT SEATING ON THE PASSENGER SIDE.. THIS NEEDS TO BE LOOKED INTO.. ALMOST EVERY BMW OWNER HAS THIS PASSENGER ISSUE...

MY TRANSMISSION WAS REPLACED AT 40,000 MILES DUE TO A FAULT. IT WOULD JUMP OR BUMP EVERY TIME I WOULD COME TO A STOP AND IT DOWNSHIFTS INTO 1ST GEAR. I ALMOST HIT A VEHICLE BECAUSE I DID NOT FULLY STOP YET AND THE CAR SURGED FORWARD. IT FINALLY WOULD GO INTO FAIL SAFE MODE OR LIMP MODE AND THE DEALER INSTALLED A BRAND NEW TRANSMISSION AND THE ISSUE WENT AWAY. I NOW HAVE THE SAME PROBLEM AT 120,000 MILES WHICH IS ONLY 80,000 MILES ON THE NEW TRANNY. I NEVER HAD A VEHICLE WHERE THE TRANSMISSION FAILED EVEN ONE TIME LET ALONE TWICE AND THEY WERE ALL INEXPENSIVE CARS/TRUCKS. I WILL NEVER BUY A BMW AGAIN BECAUSE THEY WOULD NOT HELP ME EVEN WHEN THEY KNOW THEY HAVE A DEFECTIVE PRODUCT. 2 TRANSMISSIONS WITH THE EXACT ISSUES THAT WON'T EVEN MAKE IT TO 100,000 MILES. I ALSO SEE OTHER COMPLAINTS FROM OTHERS WITH THE EXACT SAME PROBLEM AND VEHICLE. SHAME ON YOU BMW NA FOR NOT OWNING UP TO THIS ISSUE AND TAKING CARE OF YOUR CUSTOMERS. YOU HAVE LOST A GOOD CUSTOMER FOR LIFE AND I WILL TELL EVERYONE I KNOW TO STEER CLEAR OF YOUR PRODUCTS (PUN INTENDED). *JS

I PURCHASED THIS VEHICLE THINKING THAT IT WOULD BE A SAFE CAR FOR MY FAMILY AND FRIENDS. THE TRANSMISSION SEEMS TO BE SLIPPING AND AN EXCESSIVELY HARSH 2-1 DOWNSHIFT OCCURS WHEN DECELERATING TO A STOP. ALSO, TRANSMISSION "BANGS" INTO GEAR WHEN ACCELERATING FROM A FULL OR A "ROLLING" STOP. THIS OCCURRED SEVERAL TIMES ON A DAILY BASIS. ONE TIME IN SPECIFIC I WAS DRIVING WITH MY 4 YEAR OLD NIECE AND IT CAUSED HER TO BECOME ALARMED AS WELL AS INJURE HER NECK. PLEASE LET ME KNOW WHAT CAN BE DONE, THE DEALERSHIP IS SAYING THAT THEY WILL CHARGE ME AN RIDICULOUS AMOUNT OF MONEY TO UPGRADE THE SOFTWARE FOR THE TRANSMISSION. I STRONGLY FEEL THAT THIS SHOULD BE A "NO CHARGE" REPAIR OR FIX SEEING THAT NO CAR SHOULD BEHAVE IN THIS MANNER. PLEASE LET ME KNOW WHAT CAN BE DONE, AS I AM NO LONGER DRIVING THE CAR AND TAKING THE BUS IN FEAR OF CAUSING ANY INJURY TO MY LOVED ONES. *TR

EVERYTIME, COMING TO A COMPLETE STOP, TRANSMISSION HAS A NOTICEABLE "BUMP"/ROUGH SHIFT INTO 1ST GEAR, TOOK THE VEHICLE TO BMW DEALERSHIP FOR DIAGNOSIS/REPAIR, PROBLEM WAS NOT SOLVED TIME AND TIME AGAIN. NOW, APPROXIMATELY OVER A YEAR LATER, TRANSMISSION WARNING LIGHT ON, TRANSMISSION WENT INTO LIMP MODE. BMW DEALER STATES, TRANSMISSION HAS TO BE REPLACED AT MY EXPENSE DUE TO 3-2-1 DOWNSHIFT. I AM THE ORIGINAL OWNER OF THIS VEHICLE AND VEHICLE SINCE PURCHASE HAS BEEN MAINTAINED METICULOUSLY AT THE SAME BMW DEALERSHIP.

I WAS DRIVING DOWN HE HIGHWAY AT A SPEED OF 65 WHEN I TRIED TO ACCELERATE TO SWITCH LANES AND THE TRANSMISSION FAUT CAME ON AND IT ALSO STATED TO DRIVE MODERATELY. THE CAR ALSO WENT INTO A SAFE MODE TO WERE I COULDN'T ACCELERATE AND IT WOULDN'T SWITCH OUT OF THIRD GEAR. CAR THEN WAS TURNED OFF AND BACK ON AND CODE FAULT WENT ALWAYS , TWO WEEKS LATER SAME THING POPPED UP TRYING TO GET ON HIGHWAY AND NOW WON'T GO AWAY. *TR

TRANSMISSION JERKS AND SLIPS. WHEN COMING TO A STOP, THE CAR SLAMS INTO GEAR. THIS COULD CAUSE A MAJOR ACCIDENT IF THIS OCCURRED DURING WET OR ICY ROAD CONDITIONS DUE TO BREAKING TRACTION FROM WHEELS AND ROAD SURFACE. THIS IS A MAJOR CONCERN AND AFTER DOING SOME RESEARCH, THOUSANDS OF 5 SERIES BMW'S HAVE THIS PROBLEM. THE RESULT IS A DEFECTIVE MECHATRONICS WHICH COSTS BETWEEN $5000-$8000 TO FIX AND NOT COVERED BY BMW OR UNDER WARRANTY. *TR

WHEN DRIVING BETWEEN 35-40 MILES PER HOUR THE CAR HAS A VERY BAD JERK LIKE IT DOESN'T KNOW WHAT GEAR IT WANTS TO BE IN. AND SOMETIMES IT FEELS LIKE THE CAR IS GETTING HIT FROM BEHIND WITH HOW HARD OTHER JERKS ARE. *TR

VEHICLE SLIPS IN AN OUT OF 5TH AND 6TH GEAR WHEN TRAVELING AT CONSTANT 35 TO 40 MPH IN AUTO MODE AND AROUND 60 MPH IN DS MODE. NOTICEABLE OIL LEAKS AS WELL AS OCCASIONAL SMOKE FROM TAILPIPE AND VEHICLE BANGS INTO GEAR ( WHILE DOWNSHIFTING ON OCCASION) ALSO NOTICED THAT THE ELECTRICAL SYSTEM SEEMS TO CUT OUT FOR A SPLIT SECOND WHILE DRIVING. HEADS UP DISPLAY AND RADIO ILLUSTRATES THIS FINDING AS THEY SHUT OFF FOR A SECOND. THE CLOCK IS ALSO BEHIND A FEW MINUTES / WEEK BECAUSE OF THIS. *TR

INTERMITTENT HARSH 2-1 DOWNSHIFT (JOLT) WHEN COMING TO A STOP WITH LIGHT BRAKE APPLICATION. JOLTS AND/OR JERKS FELT WHEN REACCELERATING AFTER COASTING. JUDDER WHEN GENTLY ACCELERATING (MOST NOTICEABLE AT AN ENGINE SPEED BELOW 2,000 RPM). *TR

WHEN BEGINNING TO DRIVE, THE VEHICLE WOULD SLAM TO THE POINT WHERE I THOUGHT I WAS REAR ENDED. I TOOK THE CAR TO MY MECHANIC AND HE SAID IT WAS THE TRANSMISSION AND THE FIX WAS COSTLY. CONTINUES TO DO THIS AT TIMES AND WILL ALSO DO A SMALLER SCALE SLAM WHEN SLOWING TO A STOP LIGHT OR STOP SIGN. *TR

I OWN A 2004 BMW 525I WITH 119,000 MILES ON THE ENGINE. I EXPERIENCED MY CAR MAKING A THUMP SOUND AND THEN THE I WOULD LOSE ACCELERATION. I CALLED THE MECHANIC AND THEY COULD NOT FIND THE PROBLEM BECAUSE IT DID NOT SHOW THE DASH ERRORS. THIS HAD BEEN GOING ON FOR 3 WEEKS AND THEN THE MECHANIC TOLD ME MY TRANSMISSION NEEDED REPLACING. I AM DISAPPOINTED THAT THIS IS A COMMON PROBLEM AND NOTHING IS BEING DONE ABOUT THIS. I WILL NEVER BUY A BMW AGAIN. *TR

VEHICLE LUNGES FORWARD AT LOW SPEEDS SUCH AS PARKING; 4 TIMES IN THE LAST MONTH, WHEN I AM PULLING OUT OF A PARKING SPACE, THE VEHICLE HAS LUNGED FORWARD. 2 OF THOSE 4 TIMES, I ALMOST HIT THE VEHICLE IN FRONT OF ME. I HAD SHIFTED FROM REVERSE, TO DRIVE, AND JUST TAKEN MY FOOT OFF OF THE BRAKE, AND THE VEHICLE JUMPED FORWARD. THE DEALER HAS CONTINUED TO SAY THAT THINGS ARE OK AND NORMAL. THEY ARE NOT NORMAL. ADDITIONALLY, I HAVE OTHER SHIFTING ISSUES BELOW: --35MPH (5TH TO 6TH HESITATION) 5-6 HARD SHIFT (SPORT MODE GOING 45-55 MPH) SLOW TO ENGAGE REVERSE -- GEAR SHIFTING IN GENERAL IS JUST SLOPPY (THE LOANER THAT THE DEALER PROVIDED, SHIFTED GREAT). *TR

I HAVE BEEN GETTING TRANSMISSION ERROR FAULT FREQUENTLY AND NOW SEEMS TO HAPPEN VERY OFTEN. YOU CAN STOP THE CAR AND RESTART IT AND IT WILL RUN BUT WILL GENERATE THE ERROR IN A MONTH OR TWO AGAIN. *TR

TRANMISSION FAILURE ON THIS CAR. HAD TRANSMISSION REBUILT TO NO AVAIL (OVER $3000). WOUND UP GETTING OUR $$ BACK, THANK GOODNESS. APPARENTLY, IN READING ALL THE INFO ONLINE, THE 2004 525I TRANSMISSION FAILURES IS VERY COMMON. ONLY REMEDY IS A FULL-BLOWN BMW REPLACEMENT WITH THE CLUTCH ALREADY SET.

ENGINE STALLING WHILE DRIVING VEHICLE, UNABLE TO RESTART VEHICLE AFTER THE STALL. LOSS OF POWER STEERING AND BRAKE POWER ASSIST WHEN VEHICLE STALLS WHILE DRIVING. ENGINE STALLS VERY PERIODICALLY AFTER A SHORT PERIOD OF OPERATION. TOOK VEHICLE TO DEALER 3 TIMES AND WERE UNABLE TO PINPOINT THE PROBLEM. DEALER REPLACED BATTERY AND ELECTRICAL WIRING TO FIX PROBLEM BUT PROBLEM STILL CONTINUED. ALSO A BRAND NEW ALTERNATOR WAS REPLACED AND STILL SAME PROBLEMS AROSE. MESSAGE CENTER WOULD DISPLAY "TRANSMISSION FAULT" DRIVE MODERATELY. *TT

HAD MY CAR 2004 545I (78,250 MILES) SERVICED AT BMW DEALERSHIP IN LONG ISLAND FOR A DEFECTIVE TRANSMISSION PAN LEAKING AT FLUID. DEALERSHIP REPLACED AND TEST DROVE BEFORE I PICKED IT UP BUT ALSO DENOTED THAT THERE WAS AN OIL LEAK ATTRIBUTED TO VACUUM PUMP/VANOS SEALS WHICH NEEDED TO BE REPLACED SOON. AS I WAS DRIVING IT BACK TO NJ FROM LONG ISLAND DEALERSHIP I NOTICED A TRANSMISSION 'KICK/JERK/SURGE' AS CAR DECELERATED SEVERAL TIMES. DROVE THE CAR TO THE MARKET ON SUNDAY (7/25/2010) AND ON THE WAY BACK WARNING ENGINE MALFUNCTION STATING 'ENGINE OPERATING AT REDUCED OUTPUT'. EMAILED THE BMW SA IN LONG ISLAND THAT REPLACED DEFECTIVE TRANSMISSION PAN/AT FLUID AND HE FELT IT MAY BE ATTRIBUTED TO OIL LEAK AND BAD VACUUM PUMP/SEALS AND HAVE IT LOOKED AT ASAP. MY LOCAL BMW SA IN NJ JUST EMAILED ME TODAY (7/28/2010) STATING: "LOOKS LIKE THE TRANS IS BAD WAITING FOR BMWNA TO GET BACK TO US WE SENT THEM ALL THE FAULTS SORRY FOR THE BAD NEWS" REPORTS OF THESE TYPE OF TRANSMISSION 'SURGE' IS NOT ISOLATED TO 2004 545I MODEL BUT TO MANY 5-SERIES UP TO 2008 AS NOTED IN THE FOLLOWING FORUM: HTTP://WWW.BIMMERFEST.COM/FORUMS/SHOWTHREAD.PHP?T=401524 THIS ISSUE NEEDS TO BE ADDRESSED NOT ON A LOCAL DEALERSHIP BUT ON A CORPORATE, WITH GOVERNMENT OVERSIGHT, LEVEL AS IT POSES SERIOUS RISKS TO ALL DRIVERS. *TR

TRANSMISSION SLAMS INTO GEAR WHEN TAKING OFF FROM AN ALMOST STOPPED POSITION CAUSING THE VEHICLE TO JUMP FORWARD VIOLENTLY. THIS HAS LAUNCHED ME INTO INTERSECTIONS AND CAUSED ME TO ALMOST REAR-END SEVERAL VEHICLES. THIS HAPPENS ON A WEEKLY BASIS OF DAILY DRIVING. THE DEALERSHIP WANTS TO REPROGRAM THE TRANSMISSION COMPUTER AT A COST TO ME(VEHICLE OUT OF WARRANTY) EVEN THOUGH THIS IS A KNOWN PROBLEM. *TR

MY CAR WAS OUT ON A TEST DRIVE WITH A REPAIR FACILITY WHEN THE TRANSMISSION FAILED. *TR
