NHTSA Complaint #10617323 — 2009 BUICK ENCLAVE

IN THE PAST I HAD JERKING OR SLIPPING OF TRANSMISSION AT APPROXIMATELY 40 MILES AN HOUR, OR THE ENGINE WAS HAVING A COIL MISS FIRE. I HAD 3 NEW COILS INSTALLED BY DEALER UNDER WARRANTY WITH SIMILAR PROBLEMS BEFORE. TOOK TO DEALER AND THEY COULD NOT DETERMINE IF TRANSMISSION WAS SLIPPING OR ENGINE MISS FIRING, BUT NO CODE ON MISS FIRING ENGINE. SLIPPING OR HESITATING OF TRANSMISSION IS MORE LIKELY BUT CAN NOT DETERMINE SINCE DOES NOT ACT THE SAME CONSISTENTLY. STEERING NOISE STARTED IN THE WINTER APPROXIMATELY NOVEMBER 2013, BUT OFF AND ON SINCE; STEERING SEEMS A LITTLE STIFF BUT NOT FAILING YET LIKE SO MANY OTHER COMPLAINTS I HAVE READ ABOUT HERE. I WAS CHARGED $342.81 FOR DIRTY THROTTLE BODY AND OIL IN THE AIR DUST TUBE WHICH MIGHT CAUSE MISFIRE, THEY CLEANED AND REPLACED BANK 2 VALUE COVER AND CLEARED CODES, PERFORMED IDLE LEAN RESET. THIS DID NOT FIX PROBLEM ON 05/19/2014. I RETURNED ON 06/10/14 AND LEFT CAR TILL 06/11/14 THE DEALER LET ME USE A LOANER OVER NIGHT. THE DEALER SAID STUMBLE/MISFIRE AT TIMES WAS NOT ACTING UP ENOUGH TO DIAGNOSE. I HAD THE CARS AUTOMATIC TRANSMISSION FLUSH SERVICE ON 02/26/14 AND THERE WAS NO PROBLEM AT THAT TIME. IN THE COURSE OF OWNING THIS VEHICLE I HAD 3 COILS REPLACED WITH PROBLEMS STARTING 01/05/10 ONE COIL, SECOND COIL ON 08/11/10. THIRD COIL SHORTLY THEREAFTER, THIS IS AFTER COMPLAINING SINCE 12/02/2009 ABOUT ENGINE SHUDDER. THE MISFIRE/STUMBLE IS STILL HAPPENING ABOUT 40 MPH AND SOMETIMES AROUND 20MPH IF YOU ARE SLOW GOING BUT NOT ON A PULL OR ACCELERATING. WE LOVE THE CAR, BUT THE PROBLEMS ARE GETTING EXPENSIVE AND THE WORRY OF WHAT ELSE CAN GO WRONG IS STRESSFUL. I DID NOT MENTION THE WARRANTY REPAIRS OF WATER PUMP GOING OUT FRONT MOTOR MOUNT FAILURE, SHIFT LEVER, AIRBAGS, SEAT BELTS, LEFT OUT REMOTE MIRROR FAILURE, ENGINE AND TRANSMISSION CODE UPDATES. DEALER SEEM OK, SO GM CAN NOT FIX OR WILL NOT DUE TO COST. *JS
