“WHILE DRIVING MY CAR THE SPEED REDUCED ITSELF FROM 40MPH TO 5 MPH AND THE CHECK ENGINE LIGHT CAME ON ALONG WITH REDUCED ENGINE POWER ACROSS MY DASHBOARD. THE CAR STARTED SHAKING AND JERKING. IT THEN SHUT OFF WHILE I WAS DRIVING IT. I HAD IT TOWED THE NEXT DAY TO THE REPAIR SHOP AND THEY SAID A SENSOR WAS BAD IN THE GAS PEDAL AND REPLACED THE WHOLE PEDAL. 4 DAYS LATER IT DID THE SAME THING. AGAIN IT STARTED SHAKING AND JERKING THEN SHUT ITSELF OFF. I TOOK IT BACK TO THE REPAIR SHOP BUT BY THE TIME THEY COULD READ THE CODES THE CAR HAD BEEN SHUT OFF LONG ENOUGH THAT THEY COULDN'T FIND ANYTHING. THEY CLEANED THE THROTTLE BODY AND GAVE IT BACK. THE NEXT DAY IT DID THE SAME THING. I AGAIN TOOK IT BACK AND DID NOT SHUT IT OFF TIL THEY READ THE CODES. IT READ THE THROTTLE BODY WAS BAD. THEY REPLACED IT AND GAVE THE CAR BACK. 30 MILES LATER, IT STARTED ALL OVER AGAIN. I HAVE SPOKE TO GENERAL MOTORS AND THEY REFUSE TO DO ANYTHING ABOUT THIS ISSUE EVEN THOUGH THERE ARE SEVERAL FORUMS ON THE WEB WITH IMPALAS DATING BACK TO 2005 HAVING THIS SAME ISSUE. THIS IS GOING TO CAUSE AN ACCIDENT AND HURT/KILL PEOPLE IF ITS NOT ADDRESSED SOON. *TR”
