ON 10/17/2013 MY WIFE EXPERIENCED A SUDDEN ACCELERATION WHILE PULLING INTO A PARKING SPACE AT OUR LOCAL WALGREEN'S PHARMACY. AS SHE WAS PULLING INTO A PARKING SPACE IN FRONT OF THE PHARMACY THE CAR KEPT MOVING FORWARD SLOWLY ALTHOUGH SHE WAS PRESSING ON THE BRAKE PEDAL AS HARD AS SHE COULD. THE CAR CRAWLED UP THE CONCRETE CURB STOP SLOWLY AND HIT THE STEEL PIPE BOLLARD PLACED IN FRONT OF THE CURB STOP TO PROTECT THE WALKWAY FRONT OF THE STORE. NO INJURIES OCCURRED TO MY WIFE, NO ONE WAS ON THE WALKWAY AT THE TIME. ONLY DAMAGE WAS TO THE BOLLARD (BENT OVER) PLASTIC BUMPER, GRILL AND RIGHT FRONT FENDER OF THE CAR. BOLLARD AND A TRASH RECEPTACLE BROUGHT THE CAR TO A STOP. THIS IS THE SECOND TIME THIS OCCURRED. THE FIRST OCCASION WAS ABOUT A YEAR AGO WHEN I WAS DRIVING ON A NEIGHBORHOOD RESIDENTIAL STREET APPROACHING A STOP SIGN. AS THE CAR WAS SLOWING DOWN AND I WAS PRESSING ON THE BRAKE PEDAL THE CAR KEPT MOVING FORWARD WITH THE BRAKES BEING FULLY APPLIED. COULD HEAR THE ENGINE STRAINING AT AN INCREASED RPM. I LIFTED MY FOOT OFF THE BRAKE PEDAL AND JAMMED IT DOWN HARD AGAIN AND THE CAR CAME TO A STOP AT THE STOP SIGN WITH THE ENGINE IN NORMAL IDLE. IN THE THREE YEARS WE HAVE OWNED THIS CAR THESE ARE THE ONLY OCCASIONS THE PROBLEM HAS OCCURRED. *TR

ELECTRONIC STABILITY CONTROL
I OWN A 2012 TERRAIN SLE2 WITH APPROXIMATELY 20,000 MILES. ON FRIDAY, DECEMBER 13, 2013, I JOINED THE INNUMERABLE OWNERS OF GM PRODUCTS (FOUND ON THE VARIOUS OWNER FORUMS ON THE INTERNET) THAT HAVE EXPERIENCED THE SERVICE STABILITRAK LIGHT COMING ON WITH ROUGH IDLING. OTHER OWNERS HAVE EXPRESSED THE LOSS OF POWER WHEN THIS EVENT OCCURS. LUCKILY, I WAS BACKING OUT OF MY GARAGE AND NOT TRAVELING ON THE EXPRESSWAY SO I CANNOT ADVISE WHETHER THERE WAS LOSS OF POWER SINCE I WAS GOING SO SLOW. THE LIGHT WENT OFF WHEN I TURNED THE VEHICLE OFF IN ORDER TO COME INSIDE AND CALL THE DEALER (WOODY BUICK GMC IN NAPERVILLE IL). THE DEALER WAS ABLE TO FIND CODE PO300 (RANDOM CYLINDER MISFIRE) BUT THEY COULD FIND NOTHING WRONG. I WAS TOLD THE VEHICLE FIXED ITSELF (WHICH I FIND HIGHLY DOUBTFUL AND VERY DISTURBING). I AM A ONE VEHICLE FAMILY AND NOW IN A COMPLETE PANIC WHENEVER I DRIVE THIS VEHICLE. I FEAR FOR MY LIFE, MY PASSENGERS? AND OTHERS BECAUSE LOSS OF POWER CAN HAPPEN AT ANY TIME AND I AM CONCERNED ABOUT BEING REAR ENDED SINCE THE DRIVER BEHIND ME WOULD HAVE NO CLUE, AS I DON?T, THAT MY VEHICLE WILL LOSE POWER. SINCE THIS IS A HUGE SAFETY CONCERN, I AM SHOCKED THAT GM HAS NOT ADDRESSED THIS FAILURE OF ITS PRODUCTS. *TR
