I bought my 2011 Chevy Impala over a year ago with about 35,000 miles on it. After driving for about 2 months I had an issue with the "REDUCED POWER, Traction " display coming on. The car would bog down no matter how fast I tried to go. I ended up going to the dealer where I bought it. $100 later it was fixed ( knock on wood) and have'nt had a problem since. It's a DEFECTIVE SENSOR in the gas pedal. I thought my foot told me how fast the car goes but apparently not. The sensor tells the car's fuel system how fast to go so to speak. GM should have covered with a warranty but they did'nt. Hope this helps.

I had the same thing. It's a computer chip in the gas pedal that is the problem. I new pedal cost me $100 bucks. GM's warranty does'nt cover it ( it did'nt for me cause I bought the car used) That was a year ago. So far there has been no issues since.

Hi ! I bought a 2011 Impala about a year and a half ago. About two months after I owned it I was driving along and that faithful GM Traction control reduced power came on and the car bogged down about 20 mph slower. I took it to the dealer ( I live in MA) and they told me it was a defective chip in th e gas pedal. The replaced the pedal to the tune of $100. Since then ( knock on wood ) I have'nt had any issues. I have about 56,000 on the car now. Though I have to say it would have been nice if GM had picked up the tab. Good Luck !

Thank you very much. I was thinking it may cost a whole lot more. I'm glad to know the problem was resolved.

I had this same problem a few weeks ago. Though I know I purchased a used car, I checked out the carfax report and everything. Oh, I purchased it 2 months ago. Since getting the problem fixed, I am leery about it. I find myself driving in the far right lane and much slower than I normally do because of the issue.
I agree, this is a major problem and someone can get hurt. When my lights came on, I was in 5:30 pm rush hour traffic on the freeway. Something really needs to be done about this issue.

2008 Impala 125K, just purchased. Had two new tires put on and within a few hours 'Traction Control' light and 'Reduced Engine Power' warning. Judging from the thread could be the gas pedal/sensor or maybe faulty wiring. Anyway the changing of two tires could have somehow triggered this? Worth taking back to NTB to see if the can fix or is it just a waste of time and should get pedal/sensor looked at?

My 2010 Impala is back in the shop. Now they are replacing the battery. I have had messages, reduced engine power, get service, stablelizer, get serviced, and Traction Control get service. I have had this car towed 2 times. I have had Onstar diagnose problems and each time they reported do not drive car, and they called my service station. So far, I have had this problem 5 times. Once In Jan. 2013, twice in April 2013 and not twice in May 2013. I have had the throttle body replaced, a wire replaced and battery cables cleaned, an engine control module replaced, then another dealer had to program the system Now less than two weeks later, it is back in shop and this time, they are replacing my battery. This should do it, so they say. I am fortunate that I opted for the extended warranty. If I had not, this would have cost me a fortune. This is my 3rd Impala and by the looks of things it will be my last. I am shocked at all the Impala that are having the same problem and nothing is being done about it.
#431 of 485 FIXED THE PROBLEM! Changed Accelerator pedal sensor on impala
May 27, 2013 (11:52 am)
My issue was that I was four months into driving my new 2009 chevy impala and while driving on the highway driving 65mph my car showed flashing signal reading "engine reduced speed" "check stabilitrack" and my check engine was on. This all happened yesterday. After researching and hearing complaints about GM and how they are charging people anywhere from $250 - $600. We decided to take matters into our own hands. Once this happens you must fix it right away or it could lead to transmission issues. We took my car to autozone had them run a FREE test on my car order the accelerator pedal sensor which is $72.99 at autozone. And my dad replaced it today within 5 minutes. My check engine light no longer on. My car is no longer jerking and they're are no scary flashing signals! I can't believe GM did not send out a recall on that faulty part with all of these reviews. Crazy. Hope this saves someone some money!! For more info visit my YouTube video. Step by step instructions on how to DIY!
