My wife and I were returning home on I-81 traveling northbound. A warning bell sounded and she noticed the tcs(traction control system) warning light came on and a warning notice to have the stabiltrac serviced, engine power reduced warning as well. We drove the rest of the way home at a reduced speed and parked it. My wife went out today and started the car and the only indication we had was the tcs light was on. No other warnings appeared. This is something GM really needs to address since I have read about many such complaints. A recall is needed GM. This is a manufacturing problem and you should cover the costs not us consumers!!

While leaving from work I made a left turn onto a busy highway and my service traction control light, reduce engine power, and check engine light came on. Pulled over and car was wanting to turn off. Turned off car and service traction control light goes off but check engine stays on. Came home googled what could be the cause and see that many Impala owners are having the same trouble...I see a lawsuit happening if GM does not recall this!

For several weeks, the indicator on my vehicle will alert me "service traction control; reducing engine power". at first I thought this was just a glitch, until it kept happening over and over and over again. There are days when the indicator will go off and remain off for a week or two, but then it will all of a sudden come back on and remain on for a week or so. I get my vehicle serviced regularly. I have contacted GM dealership after dealership, and they have all told me there is nothing they can do. Finally, I asked for the corporate office number [xxx]. I called GM's corporate office (reference#: [xxx]) and was told that my powertrain warranty is still good but my bumpertobumper warranty has expired due to the mileage. I advised the representative ([xxx]) that I had googled this information to find out what was going on and this appears to be a known issue with Chevy implala's, and I asked why hasn't GM put out a recall on this issue. She then tells me that I need to pay and get a diagnostic check to determine the actual issue. My question to her is "why should I or any customer have to pay for something that is a reported known issue?" there representative continued to apologize and tell me there was nothing that GM could do because this was not a known issue. I referenced there representative to research for herself [xxx] and she continued to tell me there was nothing they could do.

This has happened multiple times to my 2011 Impala. I will be driving normally, anywhere from 45 to up to 65 mph, and I will get a warning saying "service stabiltrack, service traction control, engine power reduced". usually I can shut the car off and wait 5 minutes, and the messages will clear, but the check engine light will remain illuminated for the next couple of days, eventually clearing. There needs to be a recall for whatever is causing this, because there are a lot of folks with Impala having this same exact problem. We as the consumer, should not have to pay money out of our pocket, for a problem that Chevrolet caused during the manufacture of this car.

The service stabilitrak light comes on and engine power is reduced. It happened this morning while taking my kids to school...very scary thing when kids are in the car because it just starts losing power & you really cannot drive it like this..

The check stabililink / reduced engine power light came on at start. After shutting the vehicle down and restarting the light went off. I was traveling on the highway when the reduced engine power light came on. I pulled over, restarted the car and it was fine. After stopping and restarting several more times, the engine light remains on and the check. The stabilizing warning continues. The car is completely unreliable at this time. Since this occurred over easter, there are no mechanics available, leaving me with no car and cancelled appointments and lost wages to start the week.

Driving 30 mph in a small town. A "binging" noise sounds 3 times and the traction control warning light as well as the check engine light came on. Vehicle messaging system stated that to "service stabilitrak, " "service traction control, " and "engine power reduced. The acceleration was noticeably reduced as well as a significant difference in maintaining speed. Merging onto a highway the cruise control would not kick in when setting speed which made it difficult to manage a 65 mph speed limit.

My wife was driving on the highway and out of the blue the stability control and reduce engine power light came on the message display. There were no weather conditions at the time. This has happened 6 times total. One time it happened as she was warming up the car. All of a sudden it started shaking and she felt as if it was about to take off into space. She turned it off three times - even tried to drive it and move to another parking place and turned if off again before it finally stopped shaking.

My 2011 Impala is reading "service throttle. Reduce engine power" and then proceeds to shut down. Even after replacing accelerator pedal position sensor, vehicle is still reading same errors. This is very dangerous because there is no limitations to when the vehicle shuts off. After extensive research, a lot of people are having the exact same issue and Chevrolet hasn't attempted to do anything about it. Please help!

While driving on city beltway, I was changing lanes at 50 -55mph when my car experience shudder and the messages that came on screen was engine reducing power, check stability control, check traction control lights flash and what appeared to be rough idling. The next incident happen off and on for several days. The last known was 1/3/2013 630am and 115pm I would have to sshut down and restart until the message disappears. The thing that really shook me up was when I was merging onto the highway in the morning around 6:45am there was a semi and other vehicles behind me so I attempted to merge at about 30-50 when the messages appeared and the semi was practically on my tail. My heart jumped out my chest but I remained calmed and luckily there was a median strip ahead. I ask myself situation could have gone wrong and caused a major accident or gotten killed from being rammed from behind all because I could'nt accelerate.I have a small video to back this up. I took it to the dealer and they said that there was no recall notice and that they would need to get the code and charge me $129 for diagnostic. This is clearly a safety issue and who knows how many was killed behind this.

On 5/11/12, the "service stabilitrak" light came on; then a notice that the engine power was reduced came on. I called the dealer for service and he said I could bring it in on 5/14. I asked if it was dangerous to drive in the meantime and he said no. I was driving on 5/12 and was stopped in traffic waiting to turn left. I went to turn left and experienced a greatly reduced response from the gas pedal which was frightening. The dealer just called me on 5/14 and said the problem was in the accelerator pedal and he is replacing it. I found a number of complaints online of this same issue going back to the 2007 model. I think this should prompt a safety recall, since a non-responsive accelerator pedal is a safety issue.
