NHTSA Complaint #10482428 — 2009 CHEVROLET IMPALA

PURCHASED VEHICLE ON 9/6/2012 USED WITH 27,479 MILES. ON 9/19/2012 WITH 27,960 MILES, I WAS ACCELERATING ON AN ONRAMP GETTING ON A HIGHWAY AND TWO MESSAGES APPEARED ON MY DASH: "REDUCED ENGINE POWER" AND "SERVICE TRACTION CONTROL AS WELL AS THE CHECK ENGINE LIGHT. EXPERIENCE ROUGH AND HESITANT SHIFTING BETWEEN GEARS AND COULD NOT GO FASTER THAN 35MPH. WAS ABLE TO SAFELY NAVIGATE HOME ON SIDE ROADS. I TOOK IT TO THE DEALER I PURCHASED IT FROM FOR SERVICE AND WAS TOLD IT WAS READING CODE P2138 AND THE THROTTLE PEDAL ASSEMBLY NEEDED TO BE REPLACED. THE SERVICE WAS COVERED UNDER THE DEALER'S WARRANTY AND I WAS SET TO GO. FLASH FORWARD TO 10/24/2012 WITH 29,355 MILES, I WAS DRIVING ON A SIDE ROAD AND THE SAME MESSAGES CAME UP. I CALLED ON STAR AND THEY PERFORMED A DIAGNOSTIC WHICH RESULTED IN THE COMPUTER READING CODES P2138 AND C0242. EXPERIENCED OUT OF CONTROL WHEEL SPINNING AND SENSITIVE BRAKING. TOOK IT TO A DEALER IN THE AREA I WAS CURRENTLY IN TRAVELING FOR BUSINESS AND THEY COULD NOT DIAGNOSE WITH ANY ISSUE. ALL CODES AND LIGHTS WERE NOT ENGAGED. I STILL DID NOT FEEL SAFE DRIVING MY VEHICLE DUE TO PROBLEM WITH ACCELERATOR AND HAD TOWED TO THE PURCHASING DEALER NEAR MY HOME. THEY ALSO COULD NOT DIAGNOSE WITH ANY ISSUE AS THEY COULD NOT DUPLICATE THE ERROR. THIS IS A SERIOUS SAFETY CONCERN AND A PROBLEM (ESPECIALLY ON THE HIGHWAY) WITH A POPULAR MODEL. I HAVE ALSO FILED A COMPLAINT WITH GM ON THIS ISSUE AND AM HOPING TO HAVE IT RESOLVED IMMEDIATELY. *TR
