“The following has happened twice to me in the last 3 months. I was driving on the freeway 65-70mph when the service traction control/engine power reduced lights came on dash. My car then lost all power on the freeway and my speed was reduced to under 35mph. After stopping the vehicle and turning it off for approximately 5 minutes, the car started back up.”
NHTSA complaint #10605490, filed 2014-06, 133,287 miles“Driving down highway when check engine light and engine power reduced appeared on my dash. Soon after my speed and power was cut from 70 MPH to under 40. I got another message saying service throttle disabled and my car lost all ability to accelerate and steer. I was forced to pull over and waited until it started up again. This is a dangerous flaw that is happening to many GM owners. Please recall for everyone's safety.”
NHTSA complaint #10587458, filed 2014-05, 60,000 miles“2008 Impala has bad gas pedal while you are driving the traction light and engine light comes on you lose a lot of the engine power until the traction light goes off this is very dangerous. I called gmc and took it to a dealer they put it on the machine first I was told it was sensor in the pedal. Next I was told it was the wiring harness. By the same dealer now I don't know what to do I think something dangerous should be fixed by the dealer but they say it is not covered.”
NHTSA complaint #10368456, filed 2010-11, 54,000 miles“Th engine of my 2008 Impala completely shut off on two occasions approximately two years ago after hitting a relatively large pot hole. In the first incident, I was traveling west bound on snell road (oakland township, mi) between orion and rochester road and hit a large pot hole traveling approximately 40 miles per hour and the vehicle engine and electrical system completely shut off. As I recall, I steered the vehicle (manually) to the side of the road, put the vehicle in park, and restarted the engine. No other cars were coming either way. …”
NHTSA complaint #10615472, filed 2014-07, 65,000 miles“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. …”
