Open the full vehicle complaint log (all categories)THIS IS TWICE THAT I'VE RECEIVED THE P2138 THROTTLE BODY SENSOR CODE, WHICH CAUSES REDUCED ENGINE POWER AND HAS SUBSEQUENT ISSUES AROUND STABILITRACK/AWD. THE FIRST TIME WAS IN THE MIDDLE OF AN INTERSECTION, WE LIMPED OUT OF THE INTERSECTION AT 3 MPH. TODAY, MY WIFE LIMPED HOME FROM THE STORE. THIS IS EXTREMELY FRUSTRATING AND SHOULD HAVE BEEN RECALLED A LONG TIME AGO!! *TR
WHEN TRAVELING ON A VERY BUSY INTERSTATE, I BACKED OFF THE GAS AND WENT TO ACCELERATE WHEN MY VEHICLE WENT TO REDUCED ENGINE POWER. THANKFULLY, THE CAR MADE IT TO THE NEXT EXIT WHICH HAD A GM DEALER. THEY REPLACED THE ACCELERATION PEDAL POSITION SENSOR. THE CAR WAS PURCHASED NEW IN MARCH 2008. THIS ISSUE HAPPENED THE FIRST TIME IN MARCH 2012. 2 YEARS LATER IN MARCH 2014, THIS ISSUE HAPPENED AGAIN. THE SAME PART WAS REPLACED. WE CONTACTED CHEVROLET AND FILED A FORMAL COMPLAINT. WE WERE TOLD THEY WOULD PROBABLY NOT DO ANYTHING, IT'S SCARY THAT A GAS PEDAL HAS BEEN REPLACED I A VEHICLE TWICE IN 6 YEARS. *TR
WHILE DRIVING MY 2008 GMC YUKON HYBRID IN MY NEIGHBORHOOD, APPROXIMATELY 20 MPH AND DECELERATING, THE CAR SUDDENLY ACCELERATED ON ITS OWN. I FELT A MOVEMENT IN THE GAS PEDAL, EXPERIENCED A SUDDEN ACCELERATION, AND I APPLIED THE BRAKES WHICH MADE IT STOP IMMEDIATELY. THIS COULD HAVE HAD A TRAGIC OUTCOME IF I'D BEEN IN A PARKING LOT. *TR
THE VEHICLE DOES NOT ACCELERATE WHEN THE ACCELERATOR IS PRESSED. THE VEHICLE TAKE 5-10 SECONDS BEFORE RESPONDING, RESULTING IN DELAY OF MERGING AND STALLING AT STOP LIGHTS. IT BECOMES DANGEROUS WHEN ENTERING A HIGHWAY AND TAKING OFF, I HAVE HAD INDIVIDUALS ALMOST SLAM INTO ME AND I HAVE RAN INTO A CONSTRUCTION ZONE. IT SUDDENLY TAKE OFF, LEAVING THE DRIVER OFF GUARD. *TR
REDUCED ENGINE POWER INTERMITTENTLY AND WITHOUT WARNING VEHICLE WILL NOT GO ABOVE 35 MPH. HAS OCCURRED FIVE TIMES WITH A DIFFERENT "FIX" EACH TIME. ONE OF THE TIMES IT OCCURRED MY TEENAGE SON WAS DRIVING ON THE INTERSTATE AND HAD TO PULL OVER. ANOTHER TIME IT HAPPENED MY DAUGHTER WAS DRIVING THE VEHICLE AND FISHTAILED TAKING A CORNER AND HAD CONTINUED DECELERATION GOING UP THE BRIDGE. MAJOR SAFETY ISSUE! *TR
