I was stopped at a light and the front end hesitated then took off normally. I got on a highway, drove 30 miles and as I was decelerating my check engine light came on and a message to service my traction control light appeared. I looked up this problem on the internet and see that it is a common problem across many models and numerous model years. It was suggested to log the complaint.
While on freeway check engine light and traction control came on and display read "reduced engine power" and "service stabilitrak" apparently a very common and dangerous issue that has not been recalled.
Started car had car for 2yrs now no problem what so ever and the service traction and stability control and also reduced engine power came on as well as engine light it jerked went it shifted and didn't act like it had it power as always but I just drove it 35 mph to get it home this I would think is a great big safety issue shouldn't GM have a recall on this?

In may of 2013 I received a message on my dash board about stabili track, traction control and reduced engine speed. I took my car to the Chevy dealer so I could get a diagnostic, and they replaced a sensor behind my pedal. Just this weekend, Sunday April 13, 2014. The message displayed across the dashboard again. I'm going to call the Chevy dealer that fixed it the first time. Then I'm going to call GM. This is a very dangerous malfunction in these cars. From viewing and reading other stories, this is something GM should have known about and addressed.
The contact owns a 2011 Chevrolet Impala. The contact stated that while driving approximately 35 mph, there was a reduction of engine power with the illumination of the traction control and stability control warning indicators. The failure occurred on icy and dry road surfaces. The vehicle was not diagnosed or repaired. The manufacturer was notified of the problem. The approximate failure mileage was 35,000.
This is the second time this has happened. Less than a year ago, we received a service stabilitrac/service traction control/engine at reduced power message and speed dropped from 40 mph to 5 mph. We brought it to the Chevrolet dealer and a traction position control sensor was replaced. Today, on 11/24/13, we were driving 15 mph in a parking lot and received the same message resulting in the same problem. This is a safety issue due to the fact that the vehicle essentially stalls out with little to no power and nearly caused a collision at an intersection. When will NHTSA force GM to recall and fix this issue? this is extremely dangerous.
On my way to work: On highway all lights came on service traction control, service stabilitrak and engine power is reduced, and my check engine light came on as well.
While travelling on the highway, in the rain, the power to the engine suddenly and drastically slowed down. The warnings showed up on the screen" stabilitrak, traction control, engine power loss.
I have 42,000 on my 2011 Chevy Impala and the service traction control and then reduce engine power as well as the check engine light came one. I have read it is the throttle body and not covered under the extended warranty, but numerous people are having the same problem with the same exact thing and no recall or any kind of care is coming from GM.... and those of us that are still paying for our cars are getting the short end of the stick...
