My wife was driving on interstate and all of a sudden lights start flashing on dash board saying traction control, engine performance reduced and check engine light comes on. Car completely shuts down on major highway. GM needs to do something!!!! before someone seriously gets hurt or worse. Went to auto shop and they said it is the accelerator pedal sensor gone bad already at 56,103 ? I just bought the car, and only had it for 1 year. I will never buy anything GM makes or recommended there vehicles to family or friends this is ridiculous. Someone needs to care about public safety because obviously they do not. Please do a recall and save a life !!!!!

When turning on the air, there is a knocking noise on the passenger side by the glove box. Sounds like the air door actuator. It was the same thing with my 2003 Chevy Impala. Check on youtube. There more and more problems with this part. Just purchase this vehicle on July 24, 2013 at a dealership.

My car suddenly lost power while driving, no warning. Engine light came on that says "service stabilitrak". I was able to pull over safely and after a few moments I could drive again. I previously owned a 2009 Impala and this same thing happened! it would have cost $1900 to fix which is why I just decided to upgrade and by another. This appears to be a common problem with this type of vehicle.

In April 2011, I was driving on expressway and the check engine light came on and warning read reduce engine power, service traction control, service stabilitrac and then engine cut off and I coasted to shoulder of hwy. The car finally started back up after a few minutes. I had to buy $100 accelerator pedal position sensor. Now on June 28, 2013, only 2 years later, it is doing the same thing again so I have to buy another one. The warranty on it only lasted 12 months. I bought this car in October 2010 and this problem started in April 2011.this car is just 3 years old and from reading on the web, there are alot of Chevrolet having this problem. I'm reading about model years from 2007 with this same issue. GM should have addressed this problem by now. I need help with this issue!!!!

While driving on the highway and accelerating to merge, the car felt as if it dropped a gear or two and the power was noticeably reduced. The service light on the dash came on and the error message "service stabilitytrac- service traction control" came across the dash. Now the car when it accelerates "jerks" as if it's having trouble making it to the next gear when moving between 20-30mph on the speedometer. The power in accelerating after 30mph is dramatically reduced the faster you wish to go.

I was driving on a rural road at 55 miles per hour in my 2010 Impala and it was just a normal activity no excessive turning or driving. My light came on and said to service traction control. Then my light said engine power has been reduced. I was trying to get to a safe place to pull off the road an my light came on again and it said it was disengaging the throttle and my car just quit. No power steering no warning just quit and I barely got it off the road in time to keep me from crashing! the car wouldn't start for about ten minutes but finally I got it started and made it home. If I had been on the interstate this could have been tragic !

Riding along at 70 mph traction control light and check engine light comes on. Computer says engine speed is reduced. Drove two more miles to pull over safely but car cut off and computer says engine start is disabled and car would not restart until I unhooked battery. Not real fun with rush hour in St. Lewis.glad I was not [xxx]ended.

Stabilitrac light on with reduced engine power - tested and found code B 2138 replaced shorted gas pedal assembly. On April 9, 2010 the same problem occurred. The dealership charged me $463 for the first repair and now they are saying I must pay another $500 for a sensor. This is a major safety issue and a faulty system that should be under warranty and/or under gmac recall.

The contact owns a 2010 Chevrolet Malibu. The contact stated that the electronic stability control warning light illuminated as the vehicle lost power and then stalled. In addition, the power steering assist failed. The contact took the vehicle to the dealer where the traction control system was replaced. The contact stated that the problem recurred after three weeks. The failure mileage was 37,000 and the current mileage was 38,000.

The 2010 Impala was at hwy speeds at approx 65mph. The traction control light came on and the check engine light and the message display was flashing traction control failure. The lights stayed on. It also said engine at reduced speeds. The traction control failed at hwy speeds which left me coasting to reduced speeds and then the car shut off at 20 mph with no power steering or braking. I was able to coast off the highway into a parking lot off the service road.

I have a low mileage vehicle. I have remained current on all of my routine maintenance. The car recently had the warnings: Service traction control and engine power is reduced. I have looked on multiple outlets and saw that this is a common problem with this vehicle. The solution that the dealer gives is varied and coincidentally not covered under warranty.

- Farmington, MI, USA

The vehicle service stability track light comes on without reason all the time. The car reduces speed and stall when I stop. The vehicle also loses speed and shut down. I just purchased the car and cannot afford to have it repaired.
