2002 BMW 3 Series Electrical System

AFTER READING MANY FORUM QUESTIONS AND ANSWERS MY VEHICLE PROBLEM IS THE GM5 MODULE. THIS MODULE CONTROLS A WIDE SELECTION OF ELECTRICAL FUNCTION ON THIS CAR. THE FUNCTION THAT IS AT ISSUE IS THE CENTRAL LOCKING/UNLOCKING FUNCTION INITIATED BY THE KEY, KEY FOB OR LOCKING CONTROL BUTTON ON THE CONSOLE. BY RESEARCHING ONLINE IT IS APPARENT THAT THE BMW E46 MODEL HAS HAD A LONG PERIOD THAT THIS MODULE HAS BEEN A PROBLEM AND THEY HAVE NOT DONE ANYTHING TO REMEDY THE ISSUE. THIS FAULTY MODULE (GM-5) WILL LEAVE YOU LOCKED OUT OF YOUR CAR AND OR ONCE INSIDE NOT ALLOW ANY OTHER DOORS TO OPEN BY ANY MEANS. THIS CAN BE A VERY DANGEROUS IF YOU MAY BE THREATENING SITUATION. THE MANUFACTURER KNOW THIS IS A PROBLEM AS IT SPANS YEARS OF PRODUCTION. I AM JUST REPORTING THE MOST RECENT INCIDENT, THIS HAS BEEN AN ONGOING PROBLEM. WE HAPPEN TO KEEP OUR CARS ALONG TIME AND THIS IS AN EXPENSIVE AND FRUSTRATING PROBLEM.

HAVING A PROBLEM WITH MY GM5 MODULE WHICH CONTROLS LOCKING/ UNLOCKING DOORS, WINDSHIELD WIPERS AND INTERIOR LIGHTS. GOT STRANDED TODAY BECAUSE I COULD NOT UNLOCK MY CAR. THE KEY FOB WOULDN'T UNLOCK IT AND EVEN USING THE KEY IN THE DOOR DIDNT WORK. THIS IS A BIG SAFETY PROBLEM.

THE SMELL OF ELECTIRCAL FIRE AND THICK BLACK SMOKE POORED OUT THE LEFT SIDE OF MY STEARING COLUM. FLAMES STARTED TO SHOOT OUT AND ENGUFFED MY BMW TO NOTHING!

TL* THE CONTACT OWNS A 2002 BMW 325I. THE CONTACT STATED THAT THE WIRING HARNESS IN THE BLOWER MOTOR EXPERIENCED A FAILURE FOR THE THIRD TIME AFTER BEING REPAIRED. THERE WERE NO WARNING INDICATORS ILLUMINATED AT THE TIME OF THE FAILURE. THE VEHICLE WAS TAKEN TO PETER PAN BMW (1625 ADRIAN RD, BURLINGAME, CA 94010 650) 204-7600) WHERE IT WAS DIAGNOSED THAT THE WIRING HARNESS IN THE BLOWER MOTOR NEEDED REPLACEMENT. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE VEHICLE WAS REPAIRED INDEPENDENTLY. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 141,000.

I OPENED THE PASSENGER DOOR IN THE MORNING AFTER THE CAR HAD BEEN PARKED OVERNIGHT. I HAD A HOCKEY BAG WITH APPROXIMATELY 25 LBS OF EQUIPMENT SITTING ON THE PASSENGER SEAT WHICH I REMOVED FROM THE CAR AND CLOSED THE DOOR. I FORGOT SOMETHING AND WENT BACK TO THE CAR, ABOUT 40 SECONDS LATER, AND SAW A CLOUD OF WHITE SMOKE AT THE CEILING AND I OPENED THE DOOR. THE CAR HAD A STRONG SMELL OF BURNING PLASTIC/ELECTRONICS. WHATEVER WAS BURNING STOPPED AND THERE WAS NO VISIBLE FLAME. I CHECKED ALL THE ELECTRICAL SWITCHES AND ALL THE EQUIPMENT SEEMED TO WORK FINE AND NO FUSES WERE BLOWN. THE BURNING SEEMED TO COME FROM THE PASSENGER SEAT HEATER AS THERE WAS EVIDENCE OF THE SEAT COVER HAVING SMOOTH MARKS ON THE SURFACE (INSTEAD OF THE NORMAL PEBBLE SURFACE) WHERE IT MIGHT HAVE MELTED. I'M NOT SURE IF THE SEATS ARE REAL LEATHER OR SIMULATED.

CAN NOT UNLOCK CAR IN ANY WAY. THE RELAYS IN THE GM5 MODULE WHICH GIVE POWER TO THE ACTUATORS BECOME WEAK AND CAN NOT OPEN CAR. CAR CAN NOT BE OPENED WITH CAR KEY AS KEY HOLE IS ALSO ELECTRONIC. IN THE END I CANT GET INSIDE THE CAR.

LOCKS OCCUPANTS IN CAR AND CANNOT ELECTRICALLY OR MECHANICALLY UNLOCK. MANY BMW OPERATORS HAVE REPORTED THIS PROBLEM ON INTERNET BUT NO RECALL EXISTS FOR DEALERSHIPS TO REPAIR/REPLACE. HAPPENS WHEN VEHICLE IS IN MOTION OR STATIONARY, ON A CITY STREET OR HIGHWAY, TURNING OR ANYTIME THE SYSTEM LOCKS THE DOORS TRAPPING OCCUPANTS

USING KEY FOB TO UNLOCK DOORS, SOMETIMES ONLY DRIVER DOOR UNLOCKS. SOMETIMES NO DOORS UNLOCK/LOCK. INTERIOR MASTER LOCK SWITCH SOMETIMES WORKS SOMETIMES DOES NOT. REPLACED SWITCH TWICE. BEEN IN CAR AND UNABLE TO UNLOCK ANY DOORS TO GET OUT OF VEHICLE USING ELECTRIC SYSTEMS AND EVEN MANUAL IE. DOOR HANDLES. IN A NON STRESSFUL SITUATION, GOT OUT BY ROLLING DOWN WINDOW AND INSERTING KEY IN DRIVER DOOR TO UNLOCK. FOR PANIC SITUATIONS BOUGHT A WINDOW SHATTER TOOL TO BREAK WINDOWS TO GET OUT. *TR

THE BATTERY OF THE CAR DRAINS OUT EVERY MORNING AND I NEED TO JUMP START MY CAR EVERYDAY IN THE MORNING. I HAVE GOT THE BATTERY, ALTERNATOR AND THE CHARGING CIRCUIT CHECKED AND THERE ARE NO FAULTS WITH THOSE. THE BATTERY IS ONLY AN YEAR OLD. I SUSPECT THAT SOMETHING IS RUNNING IN THE BACKGROUND AFTER ENGINE STOP OR THERE MAY HAVE BEEN A SHORT CIRCUIT WHICH IS DRAINING OUT THE BATTERY. *TR

THE RED POSITIVE WIRE TERMINAL OVERHEATED AND POTENTIAL FIRE HAZARD. THE PROBLEM WOULD KILL THE BATTERY AND CAR WOULD NOT START. SHOP SAID DUE TO THE LOCATION (THE TRUNK) OF THE BATTERY THEIR WAS NOT ENOUGH GROUND. THE SHOP FIXED THE PROBLEM BY GROUNDING THE ENGINE. *TR

TL* THE CONTACT OWNS A 2002 BMW 325I. THE CONTACT WAS DRIVING 40 MPH WHEN SMOKE WAS SEEN COMING FROM UNDER THE INSTRUMENT PANEL. THE VEHICLE WAS MERGED TO THE SHOULDER WHERE THE SMALL FIRE WAS EXTINGUISHED. THE FIRE DEPARTMENT WAS NOT NOTIFIED. THE VEHICLE WAS THEN TOWED TO A LOCAL MECHANIC WHO INSPECTED THE FAILURE AND ADVISED THE CONTACT THAT THE MAIN WIRING HARNESS PLUG SHOWED EVIDENCE OF AN ELECTRICAL SHORT, MELTING THE BATCH OF WIRES THAT CONNECTED THE PORT TO THE MAIN WIRING HARNESS UNDER THE HOOD. THE CONTACT'S INSURANCE COMPANY WAS NOTIFIED OF THE FAILURE WHO REFERRED THE CONTACT TO A LOCAL MECHANIC. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND ADVISED THE CONTACT THAT THERE WERE NO RECALLS FOR THE FAILURE AND OFFERED NO FURTHER ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 48,000.

FAILURE OF THE GENERAL MODULE 5 WHICH RESULTS IN FAILING TO OPENING THE DOOR VIA THE UNLOCK BUTTON ON THE CENTER CONSOLE AND KEY REMOTE. THIS WILL ALSO RESULT IN THE DOUBLE LOCKING MECHANISM TO ACTIVATE TO WHICH PASSENGERS ARE UNABLE TO EXIT THE VEHICLE PROPERLY EITHER ELECTRONICALLY OR MECHANICALLY (MANUAL LOCKS DO NOT WORK) FORCED TO LEAVE EITHER THROUGH THE WINDOW, TRUNK THROUGH REAR SEAT IF THE CAR HAS THIS FEATURE OR POSSIBLY ONLY THROUGH DRIVER SIDE DOOR. THIS IS A SAFETY HAZARD, IF THE LOCKS FAIL ELECTRONICALLY THE PASSENGERS INSIDE SHOULD BE ABLE TO TRIGGER A MECHANICAL WAY OF EXITING THE VEHICLE.

TL* THE CONTACT OWNS A 2002 BMW 325CI. THE CONTACT WAS DRIVING 40 MPH IN RAINY WEATHER WHEN SMOKE BEGAN EMITTING FROM THE INSTRUMENT PANEL. THE CONTACT WAS ABLE TO STOP THE VEHICLE AND WITHIN MINUTES, THE INTERIOR WAS ENGULFED IN FLAMES.

DASH INDICATED TAILLIGHT WAS OUT WHEN IT WASN'T, THIS WAS RANDOM ON AND OFF FOR A FEW MONTHS. AFTER A FEW MONTHS THE DASH PANEL INDICATOR LIGHT STAYED ON. AS I WAS DRIVING ONE DAY I NOTICED THE SMELL OF SMOKE COMING FROM THE TRUNK. I STOPPED, AND NOTICED THE MELTED WIRES FROM THE TAIL LIGHT HARNESS. AS I LOOKED AT THEM I COULD SEE THEM SPARKING WHEN CERTAIN MOVEMENTS OCCURRED., VERY DANGEROUSLY AND ERRATIC. BOTH MALE AND FEMALE SIDES MELTED. I HAVE NOTICED THE OTHER SIDE WAS BEGINNING TO HAVE THE SAME SYMPTOMS, RANDOM INDICATIONS OF A TAIL LIGHT OUT WHEN THERE WAS NONE. THIS WAS BROUGHT TO THE DEALERSHIPS ATTENTION , SAVAGE BMW, AS WELL AS BMWNA. I BROUGHT UP THE FACT THAT IT WAS A COMMON PROBLEM THAT SHOULD BE LOOKED INTO, AND THEY REFUSED TO COVER IT, AND DIDNT TAKE MUCH CONCERN INTO THE MATTER. THEY WERE E CHARGING ME $400+ TO FIX JUST THE ONE SIDE. *AK

I AM LEASING A 2002 BMW 745LI . I HAVE HAD NOTHING BUT PROBLEMS WITH THIS VEHICLE. THE CAR HAS GONE TO THE BMW SERVICE CENTER A TOTAL OF 33 TIMES FOR SERVICE MECHANICAL & ELECTRICAL PROBLEMS. A FEW TIMES CAR HAS BROKEN DOWN WHILE DRIVING AND NEEDED TO BE TOWED. THIS VEHICLE IS A MANUFACTURER DEFECT. I FEEL VERY UNSAFE IN THIS CAR. I HAVE CONTACTED BMW OF NORTH AMERICA VIA PHONE, EMAILS, AND LETTERS, THEY SEEM NOT TO CARE? THE SERVICE MANAGER AT THE DEALER SHIP TOLD ME THAT THIS BMW MODEL YEAR HAS BEEN NOTHING BUT HEADACHES AND PROBLEMS FOR THEM. I FEAR FOR THE WELL BEING OF MY FAMILY WHEN THEY ENTER THIS VEHICLE. THE CAR SHUTS OFF WHILE DRIVING. THIS MODEL HAS HAD SO MANY PROBLEMS THAT BMW OF NORTH AMERICA EXTENDED THE WARRANTY ON THE CAR FROM ITS ORIGINAL MANUFACTURER'S WARRANTY. I AM PAYING FOR A PIECE OF METAL! THIS VEHICLE IS ONE PROBLEM AFTER ANOTHER. I DEMAND THAT BMW OF NORTH AMERICA STAND BY ITS PRODUCT AND PURCHASE THIS VEHICLE BACK FROM ME. THE MANUFACTURER (BMW OF NORTH OF AMERICA) BUILT A PRODUCT THAT HAS DEFECTS. THEIR OWN TECHNICIANS CANNOT FIX THIS VEHICLE. I HAVE TAKEN THIS VEHICLE TO 4 DIFFERENT BMW SERVICE CENTERS. I HAVE COMPLETE RECORDS. AGAIN I DEMAND BMW OF NORTH AMERICA TO RELIEVE ME FROM THIS VEHICLE! *TR

AFTER DRIVING MY 2002 BMW X 5 FIVE BLOCKS FROM MY HOME, I SMELLED SOMETHING BURNING AND PARKED THE CAR. FROM THE TIME IT TOOK ME TO GET OUT AND WALK TO THE REAR OF THE CAR, IT WAS FILLED WITH BLACK SMOKE AND IN SHORT ORDER THE CAR BURNED. MY INSURANCE COMPANY DECLARED IT A TOTAL LOSS AND HIRED AN INDEPENDENT PROFESSIONAL COMPANY THAT SPECIALIZES IN VEHICLE FIRES AND CAUSATION. THE CONCLUSSION OF THE REPORT WAS THAT IT WAS AN ELECTRICAL SHORT, ORIGINATING IN THE CENTER OF THE DASH. I HAVE SINCE RESEARCHED THIS SITUATION WITH BMW FIRES ON DIFFERENT WEB SIGHTS, INCLUDING ROADFLY, AND HAVE FOUND TO MY SHOCK, THERE ARE WAY TO MANY OTHER BMW OWNERS OUT THERE WITH A SIMULAR SITUATION. THIS IS AN EXTREMELY DANGEROUS PROBLEM THAT COULD CAUSE SOMEONES LIFE. IF MY GRANDCHILD OR ELDERLY MOTHER HAD BEEN IN THE CAR WITH ME, I WOULD NOT HAVE BEEN ABLE TO GET THEM OUT IN TIME! I APPRECIATE YOUR HELP. THANK YOU, HOPE PESSIS. *NM

DT: WHEN VEHICLE HAD ONLY 33 MILES EVERY SINGLE DUMMY LIGHT CAME ON THE CAR JUMPED FORWARD AND DIED OUT. IT HAD BEEN TO SEVERAL DEALERSHIPS IN DIFFERENT STATES , AND THEY SAID IT WAS ALWAYS SOMETHING DIFFERENT. WHILE GOING 65 MPH ALL THE LIGHTS CAME ON AND VEHICLE STOPPED. THE LAST TIME THIS HAPPENED THE BATTERY WAS REPLACED, AND IT HAPPENED AGAIN, AND VEHICLE ALMOST HIT SOMEONE. *AK

(1) PARKED AT A LIGHT. (2) LIGHT CHANGED, I ACCELERATED, THE ENGINE LOST POWER, VARIOUS DASH WARNING LIGHTS CAME ON, I NURSED THE CAR THROUGH THE INTERSECTION, AND PULLED OVER. TURNED THE CAR OFF, RESTARTED, DASH WARNING LIGHTS CAME ON AGAIN. AFTER TALKING WITH THE SERVICE DEPARTMENT I REACHED THE CONCLUSION THAT THE CAR WAS DRIVEABLE. WARNING LIGHTS STAYED ON BUT ENGINE POWER WAS BACK AND I WAS ABLE TO GET THE CAR HOME. (3) DEALER RESEARCHED THE PROBLEM AND FOUND A SERVICE BULLETIN WHICH EXPLAINED THE ENGINE FAILURE AS AN ELECTRICAL FAULT INVOLVING "DEFECTIVE CRIMPING" IN THE THROTTLE MOTOR, RESISTENCE FLUCTUATION DUE TO PIN CONTAMINATION, OR "FAULTY CRIMPING OR DEFECTIVE FEMALE PINS" ON A CONNECTOR. WIRING HARNESS AND THROTTLE MOTOR WERE REPLACED.*AK

THE SEAT BELT LATCH TRIGGERED THE AIR BAG DEFAULT AND THE AIR BAG HAD BECOME INOPERATIVE. THE SERVICE CHECK FAILED TO CORRECT THE PROBLEM. EVEN THOUGH THE SYSTEM WAS CLEARED, DEFAULT/INOPERATIVE AIR BAG OCCURRED WITH THE NEXT SEAT BELT LATCH. (MODEL 325XI) *JB *SCC *JB
