While driving at highway speed, Service Traction Control/Stabilitrak warning comes on. Vehicle slows and if driver attempts to accelerate (using accelerator pedal), it causes severe lurching of vehicle. This makes the vehicle basically undrivable while in the middle of traffic. You must use emergency measures to pull over (potentially across multiple lanes) off the road and while trying to do that, you are in a very high risk state of being hit. The problem is reproduceable. The manufacturer and dealer service centers are aware of this problem and it has been reported by many owners of GM vehicles since at least 2010. Search the internet and you will find hundreds of incidents being reported.

WE HAD TRUCK SINCE NEW. WE HAVE CONSISTENT SUSPENSION PROBLEMS INCLUDING STRUTS AND BUSHINGS. THE PARTS WERE DESIGNED FOR CAR AND NOT HEAVY SUV. THIS COULD RESULT IN ACCIDENT IF NOT REPAIRED AS INVOLVES STEERING AND DIRECTION. WE HAVE ALSO HAD THE BRAKE BOOSTER REPLACED 5 TIMES TO DATE. IT STARTS SQUEAKING. GM HAS SAID IT WILL NOT EFFECT THE BRAKE BUT THEY CANNOT LUBRICATE OR REPAIR UNLESS REPLACED. THIS ALSO EFFECTS OTHER GM TRUCKS ON SAME LAMBDA PLATFORM INCLUDING ACADIA AND TRAVERSE.

INTERMITTENT DIFFERENT LEVELS IN BREAK PEDAL TRAVEL. AT TIMES MY CAR STOPS NORMALLY WHEN THE BRAKE PEDAL IS FIRST PRESSED (ABOUT 2 INCHES). OTHER TIMES THE BRAKE PEDAL TRAVEL IS MUCH GREATER (ABOUT 4 INCHES OR MORE), AND THE PEDAL HAS A SPONGY FEEL. I HAVE TAKEN THE CAR BACK TO BUICK NUMEROUS TIMES, AND THEY STATE THEY CAN NOT FIND ANY PROBLEM. THIS IS A VERY SERIOUS PROBLEM, ESPECIALLY AT HIGHWAY SPEEDS, WHERE I AM NEVER SURE I WILL BE ABLE TO STOP THE CAR IN TIME TO AVOID AN ACCIDENT.

TUESDAY, 7/18/2017. I WAS COMING OVER A SMALL DECLINE ON LOCAL ROAD IN EAST BRUNSWICK, NJ. I APPLIED THE BRAKES AND CAME UPON THE TRAFFICS LIGHT AND TRAFFICS AHEAD AND THE VEHICLE SHOT FOREWORD. APPLYING THE BREAKS HAD NO EFFECT. IN FACT THE CAR APPEARED TO ACCELERATE. I DID NOT HAVE ENOUGH TIME TO AVOID HITTING THE VEHICLE IN FRONT OF ME WHICH CAUSED THAT VECHILE TO HIT ANOTHER. MY VEHICLE ACCELERATED VS BRAKING WHEN APPLYING THE BRAKES. APPLYING THE BRAKE HAD NO OR LITTLE EFFECT IN SLOWING THE VEHICLE. IS THERE, OR HAS THERE BEEN, REPORTS OF SIMILAR PROBLEMS WITH ACCELERATION PROBLEMS WITH THE BUICK ENCLAVE, 2015 MODEL ?.

ON TWO SEPARATE OCCASIONS ALL FOUR VEHICLE BRAKES LOCKED UP WHILE THE VEHICLE WAS IN MOTION. THE FIRST TIME WAS IN A NEIGHBORHOOD AND THE VEHICLE WAS COMING TO A STOP AT A STOP SIGN WHEN THE REAR BRAKES LOCKED AND WOULD NOT RELEASE. THE VEHICLE WAS SHUT DOWN FOR AN EXTENDED PERIOD AND THEN WAS ABLE TO BE MOVED A SHORT PERIOD. THE BRAKES UNLOCKED AFTER SITTING OVERNIGHT. THE LOCAL DEALERSHIP SERVICED THE VEHICLE AND SAID THE BRAKE SYSTEM WAS OUT OF CALIBRATION. TWO DAYS LATER ALL FOUR BRAKES LOCKED WHILE DRIVING DOWN A INDUSTRIAL AREA STREET. THE VEHICLE WAS ABLE TO BE FORCIBLY MOVED OFF THE ROADWAY WHERE IT SAT FROM TWO HOURS AWAITING A TOW. AN ABS SYSTEM MALFUNCTION WAS BLAMED FOR THIS FAILURE AND RESULTED IN A VERY COSTLY REPAIR, NOT COVERED BY THE MANUFACTURER.

ON THURSDAY, 7/26/2018, I HAD PARKED MY CAR IN A RESTAURANT PARKING LOT. I APPEAR TO HAVE PULLED THE VEHICLE UP ONTO A CONCRETE SPACE DIVIDER. WHEN I TRIED LEAVING THE RESTAURANT, I COULDN'T BACK OFF OF THE SPACE DIVIDER, THE CAR WOULDN'T MOVE BACKWARD, SO I TRIED PULLING FOREWORD. WHEN THE CAR CAME FREE FROM THE DIVIDER, IT SHOT FOREWORD. APPLYING THE BREAKS HAD NO EFFECT. IN FACT THE CAR APPEARED TO ACCELERATE. I WAS HEADED DIRECTLY TOWARD A CONCRETE BUILDING, SO TO AVOID HITTING THE BUILDING HEAD ON, I HAD JUST ENOUGH TIME TO TURN THE STEERING WHEEL SLIGHTLY CAUSING THE VEHICLE TO SIDE SWIPE THE BUILDING BUT IT CRASHED INTO TWO PARKED VEHICLES. IT CAUSED EXTENSIVE DAMAGE TO MY VEHICLE AND ONE OF THE PARKED VEHICLES AND ONLY SLIGHT DAMAGE TO THE THIRD. IT APPEARED THAT THE VEHICLE ACCELERATED BEYOND THE EFFORT I APPLIED TO THE GAS PEDAL, IT RAN AWAY AND THE APPLICATION OF THE BRAKES HAD NO OR LITTLE EFFECT IN SLOWING THE VEHICLE. IS THERE, OR HAS THERE BEEN, REPORTS OF SIMILAR PROBLEMS WITH ACCELERATION PROBLEMS WITH THE BUICK ENCLAVE, 2015 MODEL ?
