NHTSA Complaint #10595194 — 2008 CHEVROLET IMPALA

THIS IS THE SECOND INCIDENT WE HAVE HAD WITH OUR 2008 CHEVROLET IMPALA WHERE THIS PROBLEM HAS OCCURRED. THE MOST RECENT INCIDENT WAS ON WEDNESDAY MAY 21ST, AROUND 730 PM. MY WIFE WAS DRIVING ON A ROAD WITH A POSTED SPEED LIMIT OF 45 MILES PER HOUR, SHE SAID SHE WAS GOING ABOUT 48 WHEN THE TRACTION CONTROL LIGHT CAME ON, AND THE MESSAGING SYSTEM INDICATED "REDUCED ENGINE POWER." WHEN THIS HAPPENS THE VEHICLE SLOWS RATHER RAPIDLY, AND THEN IT IS IMPOSSIBLE TO ACCELERATE BEYOND ABOUT 30 MILES PER HOUR OR SO. DUE TO THE RAPID DECLINE IN SPEED AND THE FACT THAT THIS OCCURS WITHOUT WARNING, I BELIEVE THIS SHOULD BE AN IMMEDIATELY ACTED UPON PROBLEM. I CONTACTED GM ONLY TO BE TOLD THAT I HAVE TO TAKE IT TO GET IT LOOKED AT BY ONE OF THEIR LOCAL DEALERSHIPS, AND PAY FOR THAT DIAGNOSTIC. IN MY ONLINE RESEARCH I HAVE DISCOVERED MANY, PROBABLY IN THE HUNDREDS, WHO'VE EXPERIENCED THIS IDENTICAL ISSUE. SOME OF WHICH HAVE TAKE THEIR CAR TO GM WHO HAS CONCLUDED ACCORDING TO POST OF EXPERIENCES ON EDMUNDS THAT THEY WERE UNABLE TO DETERMINE THE SOURCE OF THE PROBLEM OR REPAIR IT. THIS IS A PROBLEM THAT REQUIRE IMMEDIATE ATTENTION. I CAN'T IMAGINE HOW DIFFERENTLY THIS COULD HAVE GONE SHOULD MY WIFE HAVE BEEN GOING 75 MPH ON INTERSTATE 80. WE LIVE ALONG I-80 AND TRAVEL IT FREQUENTLY. HOWEVER AS A RESULT OF THIS PROBLEM WE ARE ESSENTIALLY UNABLE TO TRUST OUR VEHICLE BEYOND ABOUT 50 MILES PER HOUR. *TR
