NHTSA Complaint #10561521 — 2009 CHEVROLET IMPALA

LET ME TRY AGAIN....I WAS DRIVING ON THE EXPRESSWAY, AT 55 MPH, WHEN THE CHECK ENGINE AND TRACTION CONTROL WARNING LIGHTS CAME ON, ALONG WITH THE REDUCED ENGINE POWER WARNING . I TOOK IT INTO THE DEALER, WHERE I BOUGHT IT IN AUG. 2009. I CAN'T REMEMBER WHEN THIS PROBLEM STARTED & HOW MANY TIMES PRIOR, BECAUSE THE WARNING LIGHTS WOULD GO OUT, WITHOUT ANY REDUCED ENGINE POWER WARNING OR REDUCED POWER. I THOUGHT IT WAS ONE OF WHAT IS CALLED A COMPUTER GLITCHES. IT WAS AT THIS TIME WHEN I DID GET REDUCED ENGINE POWER, WHEN I KNEW I HAD TO TAKE IT INTO THE DEALER. ON NOV.29,2010, THE ACCELERATOR PEDAL WAS REPLACED......ON JAN.05, 2011, I BROUGHT IT BACK AND WAS CHARGED ONLY HALF OF THE RATE FOR MECH. DIAGNOSIS FEE, BECAUSE I ARGUED SO MUCH, THAT THE CAR IS STILL UNDER WARRANTY, AND THEY HAVE NOT REPAIRED THE SAME INITIAL PROBLEM. I LEFT THE CAR WITH THEM TO DRIVE, THEY DROVE IT 28 MILES WITHOUT ANY PROBLEMS. ON JAN.06,2011, MILEAGE WAS 38727, THEY REPLACED THE THROTTLE BODY ASSEMBLY, N/C. I THINK IT WAS AT THIS TIME, I WAS TOLD TO RETURN THE CAR, WITHOUT SHUTTING THE ENGINE OFF, WHICH IS WHAT I DID. ON FEB.05,2011, MILEAGE WAS 39831, WHERE THEY REPLACED A A.I.R. VENT VALVE....I HAVE CHANGED LIVING LOCATIONS LAST SPRING....MEANING THERE MIGHT BE MORE TIMES THAT IT WAS BROUGHT IN.....MY MEMORY IS TELLING ME THAT THE BOTH WARNING LIGHTS WERE COMING ON AND OFF LAST YEAR, AND NOW MORE FREQUENT, WITH SLIGHT REDUCED ENGINE POWER ...81000 MILES *TR
