TL* THE CONTACT OWNS A 2011 BUICK LACROSSE. WHILE DRIVING AT VARIOUS SPEEDS, THE CHECK ENGINE LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO THE DEALER, BUT THE FAILURE COULD NOT BE DIAGNOSED. THE CONTACT STATED THAT THE ERROR CODES WERE REMOVED FROM THE VEHICLE; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS TAKEN TO DEALER WHERE IT WAS DIAGNOSED THAT THE CATALYTIC CONVERTER FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE CONTACT ALSO STATED THAT THE BATTERY OF THE VEHICLE HAD TO BE REPLACED ON SEVERAL OCCASIONS, BUT THE DEALER COULD NOT DIAGNOSE WHY THE BATTERIES WERE FAILING. WHILE DRIVING TO HAVE ROUTINE MAINTENANCE PERFORMED ON THE VEHICLE, THE VEHICLE STALLED WITHOUT WARNING. THE CONTACT STATED THAT THE ACCELERATOR PEDAL WAS DEPRESSED, BUT THE VEHICLE FAILED TO MOVE. THE VEHICLE WAS TOWED TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION FAILED AND NEEDED TO BE REPAIRED. THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURES. THE FAILURE MILEAGE WAS UNKNOWN.

CURRENTLY, MY CAR HAS 62K MILES ON IT. 2011 BUICK LACROSS CXL AWD 3.6 ENGINE. THE CAR IS JERKING FORWARD DURING THE LOW SPEEDS BETWEEN 2000-2500 RPM , WHEN I MOVE MY FOOT OFF THE ACCELERATOR, TRANNY SHIFTS FROM 1ST GEAR TO 2ND OR 3RD TO 4TH AND THIS MAKES A VERY NOTICEABLE FORWARD JERK. I HAVE NOTICED THIS 6 MONTHS AGO WHEN IT WAS NOT VERY NOTICEABLE BUT NOW IT IS GETTING WORSE. SPECIALLY IN THE CITY, DURING THE STOP AND GO TRAFFIC IT IS REALLY VERY ANNOYING AND DANGEROUS. IF I DRIVE LONGER IT GETS WORSE AND SOMETIMES I HAVE TO SLAM ON THE BREAKS TO STOP OR SLOW DOWN THE CAR SPECIALLY IF I AM GOING DOWNHILL. THIS HAPPENS WHEN I START ACCELERATING SLOWLY FROM STOP, UP TO 2000-2500 RPM AND THEN MOVE MY FOOT OFF THE ACCELERATOR. BASICALLY TRANNY SHIFTS TO THE 2ND GEAR (OR 3RD) AND JERKS VERY NOTICEABLY FORWARD. IF I KEEP ON PRESSING THE GAS PEDAL , IT KEEPS ACCELERATION WITHOUT ANY PROBLEM. IN SLOW STOP AND GO CITY TRAFFIC IF I WANT TO SLOW DOWN OR STOP, I BASICALLY TAKE MY FOOT OFF THE GAS PEDAL, THIS CAUSES CAR TO SHIFT TO UPPER GEAR AND JERK FORWARD, SOMETIMES IN THE TRAFFIC I NEED TO SLAM ON THE BRAKES TO STOP OR SLOW DOWN. HAPPENS ONLY DURING THE LOW SPEEDS (10-20 MPH) , AND STOP AND GO TRAFFIC.

TL* THE CONTACT OWNS A 2011 BUICK LACROSSE. WHILE DRIVING APPROXIMATELY 8 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE FAILED TO RESTART AND WAS TOWED TO THE DEALER FOR DIAGNOSIS. THE TECHNICIAN REPLACED THE FAULTY POWER SENSOR; HOWEVER, THREE WEEKS AFTER THE REPAIR, THE FAILURE RECURRED. THE DEALER WAS UNABLE TO LOCATE THE ISSUE. IN ADDITION, THERE WAS EXCESSIVE HESITATION WHENEVER DRIVING. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 72,000.

I NOTICED THIS PROBLEM NOT LONG AFTER GETTING CAR WHEN STOPPED IN DRIVE GOING FROM BRAKE TO GAS CAR SEEMS TO ACT LIKE ITS ON OIL SLICK THEN CATCHES ON WITH A SUDDEN JERK. IT WILL ALSO WHEN GOING FROM GAS TO BRAKE EVEN ON INCLINE WILL LUNGE FORWARD IT ALSO WILL JUST SUDDENLY SPEED UP WITH OUT ANY ACCELERATION ITS LIKE THE CAR IS IN CRUISE CONTROL. I HAVE HAD CAR IN SEVERAL TIMES AND ALWAYS THEY CANT TELL ME ANYTHING I'M NOT THE ONLY PERSON WHO NOTICES THIS ANYONE WHO IS IN CAR ASKS WHAT WAS THAT OR WHAT JUST HAPPENED. *TR

SUDDEN AND UNEXPECTED ACCELERATION DURING A LOW SPEED (<5 MPH) TIGHT LEFT HAND TURN. FIRST INCIDENT RESULTED IN CRASH AGAINST HOUSE WALL, DAMAGE TO VEHICLE. VEHICLE REPAIRED BELOW INSURANCE DEDUCTIBLE, NO DAMAGE TO STRUCTURE. SECOND INCIDENT IN A PARKING LOT, ON OR ABOUT MAY 16, 2012, ABLE TO STOP VEHICLE WITH NO CRASH. THIRD INCIDENT OCCURRED AT NEIGHBORS HOUSE JUNE 26, 2012, CAUSING CRASH. DAMAGE TO VEHICLE AND GARAGE DOOR. ALL INCIDENTS OCCURRED WHEN LIFTING FROM ACCELERATOR PRIOR TO STEPPING ON THE BRAKE TO SHIFT INTO REVERSE (VEHICLE STILL IN DRIVE, NO BRAKING). AFTER 3RD INCIDENT VEHICLE WAS DRIVABLE BUT WAS TOWED TO THE SELLING/SERVICING BUICK DEALER. VEHICLE IS STILL BEING INVESTIGATED BY DEALER. CONDITION DOES NOT OCCUR EVERY TIME IN THE SAME TIGHT LEFT HAND TURN. TYPE OF TURN IS 90 DEGREES IN DRIVEWAYS TO SIDE LOADING GARAGES AND INTO PARKING SPACES. *TR

TL* THE CONTACT OWNS A 2011 BUICK LACROSSE. WHILE THE VEHICLE WAS PARKED IN A RESIDENTIAL GARAGE WITH THE ENGINE TURNED OFF, THE VEHICLE UNEXPECTEDLY REVERSED INTO THE SIDE OF THE GARAGE DOOR AND CONTINUED TO ROLL, CRASHING INTO A CURB WHICH STOPPED THE VEHICLE. THE DRIVER SIDE DOOR AND FOUR RIMS WERE DAMAGED. THE DRIVER SIDE DOOR REQUIRED REPLACEMENT AND IN ADDITION, THERE WAS A DENT ABOVE THE FRONT PASSENGER SIDE BUMPER. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THEY INFORMED THE CONTACT THAT THE FAILURE WAS RELATED TO THE POWER TRAIN. THE CONTACT SCHEDULED AN APPOINTMENT WITH THE DEALER FOR DIAGNOSIS AND COLLISION REPAIR. THE MANUFACTURER WAS NOT MADE AWARE OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 9,142. THE VIN WAS UNAVAILABLE.

UPON LEAVING DEALERSHIP AFTER PURCHASE OF NEW CAR, TURNED RIGHT TO EXIT AND TRANSMISSION JUMPED INTO NEUTRAL, ALMOST REAR-ENDED. THOUGHT I MAY HAVE HIT SHIFTER. ANOTHER TURN FROM STOP AND TRANS JUMPED INTO NEUTRAL DURING TURN WHILE ENTERING TRAFFIC. JUST MISSED BEING HIT AND PERHAPS KILLED. MANUALLY RETURNED TO "D". LIFE THREATENING DEFECT. RET TO DEALER AND DEMONSTRATED. NEXT DAY DEALER ADVISED THAT A "MODULE" ON THE TRANSMISSION WAS INSTALLED BACKWARDS BY GM MFG. ADVISED GM DAY AFTER OCCURRENCE. LATER GM CALLED AND TOLD ME CAR HAD BEEN REPAIRED AND GET IT OR "THEY" WOULD CHARGE ME STORAGE. OBVIOUSLY, AFTER EXPOSING WIFE AND MYSELF TO GREAT RISK, WE DID NOT WANT THAT VEHICLE. NOW GM WILL NOT SPEAK TO ME AS I TRY TO ENSURE THAT THE AUTOS PRODUCED PRIOR AND POST TO MINE WERE VERIFIED TO ENSURE THEY DID NOT HAVE THE SAME LIFE THREATENING DEFECT AND REACT ACCORDINGLY. GM SEEMS NOT TO CARE. PLS NOTE: THE CAR "DROPPED" FROM DRIVE IN NEUTRAL EVERYTIME I ACCELERATED FROM A TURN INTO TRAFFIC. THIS PROBLEM WAS DEMONSTRATED TO THE DEALER; DEALER SAID PARK IT NOW. QUESTION IS HOW MANY BUICKS WERE MANUFACTURED WITH THIS VERY DANGEROUS DEFECT. THE 2 TIMES THIS HAPPENED, PRIOR TO KNOWLEDGE OF THE/A PROBLEM, IF I HAD NOT BEEN ABLE TO RETURN TO "DRIVE" AND PROCEED WITH MAXIMUM ACCELERATION, WE WOULD HAVE BEEN UNQUESTIONABLY HIT BY APPROACHING CARS. HAD MY WIFE BEEN DRIVING, HER REACTION WOULD HAVE BEEN SLOWER AND SHE COULD HAVE EASILY BEEN KILLED. THIS IS LIFE THREATENING. I DELAYED CONTACTING THE NTSB IN THAT I BELIEVED GM WOULD TAKE ACTION. I DO NOT BELIEVE THAT TO BE THE SITUATION. HELP - LIVES ARE DEFINITELY AT RISK IF ANY CARS PRIOR TO OR AFTER MINE HAVE THIS DEFECT. SUSPECT POORLY TRAINED INDIVIDUAL ON THE LINE THAT DAY "FILLING" IN. POOR ENGINEERING AS DEALER STATED THE PART WAS SO DESIGNED AS IT COULD BE INSTALLED BACKWARDS. PLEASE CONFIRM YOU ARE TAKING ACTION AS THIS IS A CRITICAL DEFECT THAT COULD VERY EASILY RESULT IN DEATH OR SERIOUS INJURY AS I CANNOT CONFIRM GM ACTION. *TR
