NHTSA Complaint #10556495 — 2012 GMC TERRAIN

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
