2011 BUICK LACROSSE Electrical System Problems

#07-06-04-019F: Intermittent Malfunction Indicator Lamp (MIL} Illuminated, OTC Pl':1.~J with Reduced Engine Power (Repair Instrument Panel (IP) to Body Harness Connector). Lost power on I-84 and had to cross over the right lane because I had no power, barely missing a rear end collision.

The component is the brakes and the brake pedal while not engaging the brakes they remained on even after the vehicle was shut off .the vehicle brake lights remained on this was not duplicated when I took the car in by the dealer of how the brake remains engaged we even when not being used I would have to release the break by pulling it up with my foot while driving . This was duplicated and witnessed by two others the dealership where I bought the car and a trusted mechanic. which no avai there was no warning light indicating any type of concern prior to it doing this. the brake pedal being slightly stuck my transmission shifts not properly and hot feeling to the car now I have a warning saying that AC will not work due to the overheating of my engine which I believe to have repaired...

FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 103 WINDSHIELD DEFROSTING AND DEFOGGING SYSTEM AND I DON'T KNOW IF ITS EFFECTING MY A/C TO I HAVE TAKEN IT EVERYWHERE TO GET FIX AND NO ONE FIXES IT COMPLETELY STILLS BLOW COOL NOT COLD LIKE IT IS SUPPOSED TO. *TR

EVERY TIME I WILL DRIVE FOR SO LONG I'D LOSE ALL POWER RADIO DASH LIGHTS HEADLIGHTS EVERYTHING AND START BLINKING AND GOING OUT AND FINALLY THE CAR WAS JUST DIE. COME TO FIND OUT IT IS ELECTRICAL ISSUES AND IT'S COSTING ME MORE THAN THE CAR IS WORTH TO EVEN GET IT BACK FROM THE SHOP.

DRIVING 60 MPH ON THE HIGHWAY. SUDDENLY THE INFORMATION PANEL FLASHED STABILITRAK SERVICE REQUIRED (OR SIMILAR) THEN LOW POWER MODE. CAR WENT FROM 60 TO 30 MPH ON THE HIGHWAY. UNABLE TO SPEED UP. NEEDED TO PULL OVER TO THE SIDE OF THE ROAD. TURNED CAR OFF. TRIED TO RESTART AND IT WOULDN'T RESTART FOR SEVERAL TRIES. RESTARTED AND STILL SAID LOW POWER AND WAS IDLING LOW. TRIED AGAIN AND WAS NORMAL. THIS HAS HAPPENED SEVERAL MORE TIMES AND ALWAYS IS SIMILAR. SOMETIMES IT DOESN'T HAPPEN AT ALL IN A 30 MILE TRIP, SOMETIMES IT HAPPENS 3 TIMES. VERY DANGEROUS! COULD BE REAR ENDED! I HAVE READ MANY OTHER ACCOUNTS OF THIS HAPPENING IN THE 2011 BUICK LACROSSE. AFTER THIS THE CHECK ENGINE LIGHT STAYED ON. WHEN I HAD THE AUTO PARTS STORE RUN DIAGNOSTICS IT FLAGGED MULTIPLE MISFIRES, THROTTLE POSITION SENSOR 3 TIMES, POWER CONTROL MODULE INDICATOR, TRACTION CONTROL....

TL* THE CONTACT OWNS A 2011 BUICK LACROSSE. WHILE DRIVING THE VEHICLE, THE AIR CONDITIONING, HEATING, AND DEFROSTER FAILED TO FUNCTION. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS NOT TAKEN TO A DEALER OR AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 112,000.

WHILE DRIVING UPHILL IN THE WINTER, WENT TO TURN INTO NEIGHBORHOOD AT TOP OF HILL, JUST AS TURNING THE VEHICLE, VEHICLE DIED. EVERYTHING STOPPED WORKING. ENGINE SHUT OFF, BRAKES WOULDN'T WORK, STEERING WHEEL LOCKED, LIGHTS WENT OFF, THEN WOULDN'T START. THEN THE VEHICLE INSTRUCTED TO ROLL DRIVER WINDOW DOWN THEN UP, ROLL RIGHT WINDOW DOWN THEN UP. ALMOST LIKE IT WAS TRYING TO REBOOT. BUT THIS HAPPENED IN THE MIDDLE OF DRIVING. AFTER TRYING A THIRD TIME TO START, IT STARTED. ALL INFORMATION WAS GONE, NO MILEAGE, OIL LIFE GONE, TRIPOMETER GONE. DROVE VEHICLE HOME, JUST A BLOCK AWAY AND BEEN TOO SCARED TO DRIVE THE VEHICLE SINCE. *TR

POTENTIAL FATAL SAFETY HAZARD WITH DOOR LOCK PULL TOGGLES WHEN AN ACCIDENT DISABLES THE BATTERY. IN NORMAL OPERATION, THE ELECTRICAL SYSTEM ALWAYS RETRACTS THE DOOR PULL TOGGLES COMPLETELY INTO THE TOP OF THE DOOR DURING ANY SHIFT OF THE VEHICLE OUT OF PARK. THE PULL TOGGLE DISAPPEARS COMPLETELY INTO THE DOOR WITH NO PORTION EXPOSED. IF THE VEHICLE BATTERY IS DISABLED, AS IN MINOR CRASH, THE ELECTRIC WINDOWS CANNOT BE OPERATED AND THE DOOR CANNOT BE OPEN MANUALLY. THE OCCURPANT IS LOCKED WITHIN THE VEHICLE UNTIL A WINDOW IS BROKEN OUT. THERE IS SIMPLY NO WAY TO OVERRIDE THE ELECTRIC SYSTEM TO EXIT THE VECHILE. PULLING THE DOOR HANDLE DOES NOT OVERRIDE THE ELECTRIC DOOR LOCKS. A SIMPLE FIX WOULD MERELY BE TO MAKE THE PLASTIC PULL TOGGLES 3/4 IN. LONGER SO THAT SOMONE CAN GRAB THE TOGGLE AND PULL IT TO THE UNLOCKED POSITION EVEN THOUGH THE VEHICLE HAD...

THIS VEHICLE STALLS/CUTS OFF WHILE DRIVING. IT CAN OCCUR WHILE DRIVING OR TAKING OFF FROM A STAND STILL. IT MAINTAINS A STORED HISTORY CODE P0014 AND AFTER SERVICE WILL REAPPEAR. ESPECIALLY DANGEROUS WHILE DRIVING IN THE NATIONAL CAPITAL AREA. BUICK HAS A NOTICE ABOUT THE ENGINE CONTROL MODULE AND THAT HAS TO BE REPROGRAMED FOR THAT VEHICLE MODEL AND MY VIN NUMBER FALLS WITHIN THAT BULLETIN. THE PROBLEM IS THAT IT DOESN'T WORK AND THE VEHICLE SHUTS OFF AT A MOMENTS NOTICE. RIGHT NOW I'M AFRAID THAT MY LIFE OR SOMEONE ELSE IS IR REAL DANGER. UNFORTUNATELY I'M NOT THE ONLY ONE. WHILE SEARCHING FOR A SOLUTION I FOUND NUMEROUS OWNERS WITH THE SAME PROBLEM/ SAME COMPLAINT. I HOPE IT DOESN'T TAKE THE LOSS OF LIFE TO ADDRESS THIS ISSUE.

VEHICLE COMPLETELY DEAD AFTER ALL TYPES OF ELECTRICAL MESSAGES DISPLAYED WHEN TRYING TO START. CAR WAS STATIONARY BOTH TIMES. THIS FIRST HAPPENED EARLY FEB 2016; THEN REPEATED SIMILAR SCENARIO 20 DAYS LATER. CAR WAS TOWED BOTH TIMES. LOW MILEAGE 52,278 MILES. MESSAGES GENERIC, DEALER COULD NOT DETERMINE PROBLEM AND CONTACTED THE GM CUSTOMER CENTER ALSO. NOTHING DONE FIRST TIME. SECOND TIME DEALER STARTED UPDATING ALL THE ELECTRONIC MODULES-ALTHOUGH AGAIN NO SPECIFIC CAUSE AND EFFECT COULD BE IDENTIFIED. MODULES UPDATED (EBCM, BCM ECM, ETC. ABOUT 27 MODULES. THUS FAR CAR HAS NOT BEEN DEAD AGAIN WITH EXCEPTION OF BATTERY ISSUE (ALREADY ANOTHER WARRANTY REPLACEMENT FOR ORIGINAL). MY CONCERN: IF THESE ELECTRONIC MODULES (COUPLE THOUSAND OF DOLLARS) ARE THE PROBLEM, HOW COME IT WAS NOT A RECALL VS REPAIR. OWNER SHOULD NOT BE A HOSTAGE TO A SOFTWARE UPDATE FOR A REPAIR TO MAKE THE CAR START? OF NOTE; MY CAR HAS...

DEFROSTER,HEAT,A/C,FAN SPEED,RECIRC, HEAT/COOL SEATS FUNCTIONS FAILED (STOPPED WORKING COMPLETLY) WHILE DRIVING IN A SNOW STORM ON JANUARY 12, 2016 ON HIGHWAY US 131 TO TRAVERSE CITY, MI. FOUND RECALL INFORMATION NHTSA # 11V149000. BROUGHT TO DEALER. DEALER SAID NOT COVERRED UNDER RECAL DUE TO VIN #, AND OWNER COST OF $400 + TO REPAIR. CONTACTED BUICK CUSTOMER CARE. SPOKE WITH ASIA AND LESLIE ON 1/15/16, WHO SAID GM COULD NOT HELP. I DESCRIBED LANGUAGE OF THE RECALL AS BEING IDENTICAL TO THE SAFETY HAZARD DESCRIBED IN THE NHTSA LANGUAGE: "WINDSHIELD DEFROSTING AND DEFOGGING SYSTEMS" ON THESE VEHICLES, THE SOFTWARE IN THE ELECTRONIC CLIMATE CONTROL MODULE MAY DISABLE THE ABILITY TO ADJUST THE HEATING, VENTILATION, AND AIR CONDITIONING SYSTEM SETTINGS. IF THIS HAPPENS, THE DRIVER WILL NOT BE ABLE TO CONTROL THE COOLING AND VENTILATION FOR THE VEHICLE. CONSEQUENCE: IF THIS CONDITION AFFECTS THE DEFROST SYSTEM WHEN IT IS REQUIRED, IT...

VEHICLE HAS BEEN OPERATING NORMALLY. IT JUST CAME OFF WARRANTY A FEW WEEKS BACK. WIFE CAME HOME AND PARKED THE VEHICLE IN THE DRIVEWAY. WENT OUT SEVERAL HOURS LATER TO GO SOMEWHERE AND IT WOULD NOT START. THERE WERE NO WARNINGS OF A PROBLEM. WHEN WE TURNED THE IGNITION KEY WE HEARD A FEW CLICKS AND THEN NOTHING. LIGHTS WE NOTICEABLY DIM. WE WERE ABLE TO GET IT STARTED WITH A JUMPER AND LET IT RUN FOR A WHILE. IT WILL BE SERVICED IN THE MORNING. IT APPEARS THE PROBLEM IS WITH THE BATTERY OR THERE IS AN ELECTRICAL PROBLEM IN THE SYSTEM. WHILE WE WERE RUNNING, WE CHECKED TO SEE IF THERE WERE ANY CODES AND COULD NOT FIND ANY. THE CAR WAS PARKED ON ABOUT A 5% INCLINE FACING DOWN. WE USED THE INCLINE TO MOVE THE CAR TO A FLAT AREA WHERE WE WERE ABLE TO JUMP...

CAR WAS PARKED IN OUR GARAGE AT 2:30 PM. I WENT INTO THE GARAGE AT 7:45 PM AND FOUND IT EXTREMELY HOT (115F), OPENED THE GARAGE DOORS AND TRIED TO START THE CAR TO GET IT OUT OF THE GARAGE.

ON MORE THAN 10-15 OCCASIONS I'VE EXPERIENCED INTERMITTENT FAILURE OF THE KEYLESS IGNITION, WHEREBY THERE IS ONLY ONE CLICK AND THEN NO ABILITY TO START MY VEHICLE UNLESS I CONTINUE TO PRESS THE BUTTON WHILE TURNING OFF ANY AND ALL AC, RADIO, POWER ETC. I PURCHASED THE CAR USED 1 YEAR AGO IN EXCELLENT CONDITION BUT NOTICED THAT IT ALREADY HAD A NEW BATTERY THAT WAS INSTALLED EARLIER IN 2013.THE VEHICLE IS A 2011 AND THAT SEEMED VERY ODD. WHAT I'VE NOTICED IS THAT THE BATTERY TERMINALS CONTINUALLY CORRODE MOSTLY ON THE "POSITIVE" TERMINAL AND I'VE REMOVED AND BRUSHED THEM SEVERAL TIMES AND TIGHTEN, AND THAT SEEMS TO WORK WHEN IT JUST ABSOLUTELY WON'T START. BIG INCONVENIENCE WHEN I'M USUALLY DRESSED IN A SUIT... UNFORTUNATELY, I'VE TAKEN IT TO THREE DIFFERENT GM BUICK DEALERSHIPS OVER THE PAST MONTH AND A HALF AND IT NEVER WILL REPRODUCE THE DEFECT WHEN I'M...

2011 BUICK LACROSSE. CONSUMER WRITES IN REGARDS TO VEHICLE INTEGRATED FLIP KEY SYSTEM. *SMD THE CONSUMER STATED HE NOTICED A PROBLEM WHILE DRIVING HIS MOTHER'S VEHICLE. IN ORDER TO ACTIVATE THE IGNITION, THE DRIVER MUST EXTEND THE BUICK INTEGRATED FLIP KEY. AFTER THE FLIP KEY WAS INSERTED INTO THE IGNITION, THE DRIVER MUST TURN THE BUICK INTEGRATED FLIP KEY DEVICE TO START THE VEHICLE. DURING THE PROCESS, THE DRIVER OFTEN INADVERTENTLY PLACED PRESSURE WITH HIS OR HER THUMB OR INDEX FINGER ON THE TRUNK LATCH DISENGAGEMENT SWITCH. THE SWITCH DISENGAGED THE TRUNK SECURITY LATCH. HOWEVER, THE TRUNK DID NOT OPEN, TO THE POINT WHERE IT WAS NOTICEABLE TO THE DRIVER OR PASSENGERS. HOWEVER, WHILE STOPPING, THE UN-LATCHED TRUNK INEVITABLY OPENED.

WHEN TURNING LEFT AT A TRAFFIC LIGHT, MY CAR LOST POWER AND I WASN'T SURE I WAS GOING TO MAKE IT AROUND THE CORNER. AFTER A FEW SECONDS MY CAR REGAINED POWER. 45 MINUTES LATER, I MADE A RIGHT TURN INTO HEAVY TRAFFIC AND THEN FELT A SUDDEN LURCH. I LOOKED IN THE REAR VIEW MIRROR AND SAW THAT MY TRUNK HAD POPPED OPEN. I MANAGED TO GET OFF THE HIGHWAY, PARKED THE CAR AND TURNED OFF THE IGNITION. I GOT OUT, CLOSED THE TRUNK, GOT BACK IN THE CAR, AND FASTENED MY SEATBELT. BEFORE I COULD CLOSE THE DOOR, THE TRUNK POPPED OPEN AGAIN. THIS OCCURRED THREE TIMES BEFORE THE TRUNK FINALLY STAYED CLOSED. A FEW MINUTES LATER, I PARKED THE CAR, OPENED THE DOOR, STARTED TO GET OUT AND THE WARNING CHIME SOUNDED. I GOT BACK IN AND SAW THAT THE ON THE CONSOLE SHIFT LEVER THAT INDICATES...

WHILE DRIVING VEHICLE, VEHICLE ELECTRONICS WENT INOPT WHILE CRUISING DOWN HIGHWAY AT 60 MPH. SPEEDOMETER, INSTRUMENT CLUSTER, TURN SIGNALS, NAVIGATION AND RADIO WERE ALL INOPT. *TR

THIS VEHICLE HAS THE PUSH BUTTON KEYLESS START. PAGE 10-89 OF THE OWNER MANUAL DESCRIBES THE METHOD TO MOVE THE TRANSMISSION LEVER FROM PARK TO NEUTRAL WITHOUT STARTING THE ENGINE, FOR THE PURPOSE OF TOWING THE VEHICLE OR MOVING IT WITHOUT STARTING THE ENGINE (IF THE CAR BATTERY IS DEAD OR THE ENGINE WILL NOT START FOR ANY OTHER REASON), SUCH AS ONTO A TOW TRUCK FOR TRANSPORT TO A SERVICE CENTER. THE MANUAL SAYS TO SET THE PARKING BRAKE (THIS CANNOT BE DONE IF THE CAR BATTERY IS DEAD BECAUSE THE PARKING BRAKE IS ELECTRICALLY OPERATED), SELECT THE ACCESSORY MODE (BY PUSHING THE START BUTTON TO SHOW AN AMBER LIGHT AS DESCRIBED ON PAGE 9-20), THEN SQUEEZE THE SMALL LEVER ON THE FRONT OF THE TRANSMISSION LEVER, AND MOVE IT FROM PARK TO NEUTRAL. THIS DOES NOT WORK. THE LEVER CANNOT BE MOVED OUT OF PARK. APPLYING THE FOOT...
