NHTSA Complaint #10689379 — 2011 CHEVROLET IMPALA

MY WIFE WAS DRIVING HOME FROM WORK GOING 65 DOWN A VERY BUSY HIGHWAY. ALL OF A SUDDEN THE REDUCED ENGINE POWER LIGHT, CHECK ENGINE, STABILITY CONTROL OFF, AND TRACTION CONTROL LIGHTS CAME ON. THE CAR BEGIN TO LOOSE SPEED. LUCKILY SHE WAS ABLE TO GET OVER TO THE RIGHT SHOULDER WITHOUT ANYONE HITTING HER. WHEN SHE GOT TO THE SHOULDER THE CAR WAS RUNNING REALLY ROUGH. SHE TURNED IT OFF WAITED A FEW MINUTES AND RESTARTED IT. IT THEN RAN FINE BUT THE CHECK ENGINE LIGHT REMAINED ON. SHE MADE IT HOME AND WAS SCARED TO DRIVE IT AGAIN. I TOOK IT TO WORK LAST NIGHT AND MADE IT ABOUT HALFWAY TO WORK AND IT DID THE EXACT SAME THING EXCEPT I WAS ABLE TO GET IT TO MAINTAIN 45MPH. WHEN I CAME TO A TRAFFIC LIGHT THOUGH THE ENGINE WAS RUNNING SO ROUGH THE CAR WAS VERY HARD TO STOP. I MADE IT TO WORK. WHEN I CAME OUT TO GO HOME THE FIRST STOP LIGHT I CAME TO IT STARTED ACTING UP AGAIN. FROM THE LIGHT I WAS BARELY ABLE TO GET IT TO GO 25MPH. I PULLED OVER AND SHUT THE CAR OFF WAITED A FEW MINUTES AND RESTARTED. EVERYTHING WAS FINE AGAIN. I MADE IT ABOUT 5 MILES AND ALL THE LIGHTS CAME ON AGAIN BUT I WAS ABLE TO MAINTAIN 45MPH IN THE 55MPH ZONE I WAS IN. I TOOK IT TO MY REPAIR SHOP AND THEY SAID IT NEEDS A THROTTLE BODY. THEY ALSO SAID GM HAS HAD ALLOT OF ISSUES WITH THESE. I CALLED MY GM DEALER TO SEE IF IT WOULD BE COVERED UNDER 5 YEAR 100K MILE WARRANTY AND THEY SAID THAT IT ISN'T. IF THERE HASN'T BEEN AN ACCIDENT CAUSED BY ONE OF THESE THROTTLE BODY ISSUES YET I WOULD BE SURPRISED. IT'S VERY DANGEROUS IN HEAVY TRAFFIC AND ALL OF A SUDDEN YOU CAN'T GO. *TR
