What 505 owners told NHTSA about the 2011 Chevrolet Impala Eco Eassist

THE CAR KEEPS RUNNING AFTER IT IS TURNED OFF. THE FAN ALSO KEEPS RUNNING, THEN THE NEXT MORNING THE CAR WOULDN'T START. THE AIR WON'T TURN DOWN AND SOMETIMES IT DOESN'T WORK AT ALL. THERE DOESN'T SEEM TO BE A DIFFERENCE BETWEEN AIR AND DEFROST. WHILE I AM DRIVING, THE LIGHT KEEP GETTING DIM, THEN BRIGHTER, THEN DIM, THEN BRIGHT. IT WAS THE NEXT MORNING THEN WHEN IT WOULDN'T START! SOMETIMES WHEN WE PUT THE KEY IN, WE COULDN'T GET IT OUT. WE HAD TO KEEP TRYING TO TURN IT ON AND OFF, THEN IT FINALLY LET US TAKE THE KEY OUT. *TR

WHILE I WAS DRIVING THE SERVICE STABILITY PACK AND TRACTION CONTROL LIGHT CAME ON AND IMMEDIATELY AFTER THE REDUCED ENGINE POWER CAME ON. THE CAR THEN JERKED, AND SHUT OFF WHILE I WAS STILL DRIVING, AND WOULDN'T START AGAIN UNTIL APPROXIMATELY 30 MINUTES LATER. THERE WERE NO WET NOR ROAD HAZARD CONDITIONS THAT WOULD HAVE CAUSED THIS TO HAPPEN. FURTHERMORE, I WAS DRIVING AT 60MPH WHEN THIS OCCURRED IN MODERATE TRAFFIC AND ALMOST GOT REAR ENDED. THIS IS A VERY UNSAFE ISSUE, AND I WAS TOLD THAT THE GAS PEDAL NEEDS TO BE REPLACED. SINCE THEN MY VEHICLE HAS DONE THIS SEVERAL TIMES. THIS ISSUES NEEDS TO BE RECALLED BECAUSE A LOT OF INDIVIDUALS HAVE COMPLAINED ABOUT HAVING THE SAME ISSUES WITH THE IMPALA. WHAT IS IT GOING TO TAKE AN INJURY OR FATALITY FOR A RECALL ON THESE VEHICLES. MOREOVER, ANY VEHICLE THAT SHUTS OFF WHILE DRIVING AT ANY SPEED BECAUSE OF AN ISSUES WITH THROTTLE BODY/GAS PEDAL NEEDS TO BE RECALLED BECAUSE THIS IS A MAJOR SAFETY ISSUE. *JS

THE SERVICE STABILITRAK, TRACTION CONTROL, AND REDUCED ENGINE POWER WARNINGS CAME ON AND THE CAR STARTED TO LOSE POWER GOING AROUND A CURVE. I TEMPORARILY LOST THE ABILITY TO ACCELERATE NEARLY CAUSING ME TO GET REAR ENDED BY A VEHICLE BEHIND ME. SINCE THE INCIDENT OCCURRED THE CAR HAS BEEN VERY SLUGGISH AND UNSAFE TO OPERATE. I AM PLANNING TO GET THIS SERVICED ASAP. AFTER READING MANY FORUM POSTS ONLINE REGARDING THIS SAFETY ISSUE, I BELIEVE A RECALL SHOULD BE ISSUED. I WAS SHOCKED TO SEE HOW RAMPANT OF A PROBLEM THIS AND THAT IT IS USUALLY CAUSED BY A FAULTY THROTTLE BODY THAT ISN'T COVERED IN THE 100K MILE POWERTRAIN WARRANTY. MYSELF AND MANY OTHERS FROM WHAT I HAVE READ BELIEVE THIS TO BE A VERY DANGEROUS MALFUNCTION. IF THIS WERE TO HAPPEN AT HIGH SPEEDS ON THE HIGHWAY SOMEONE COULD VERY EASILY BE KILLED IF THEIR CAR LOSES POWER DUE TO THIS. *TR
