Chevy Impala traction control light & engine light

edited January 17 in Chevrolet
When I am driving on (usually) wet or slippery pavement the traction control light will go off in tandem with engine light. The messages will alternately read service traction control and reduced engine power. Upon turning the car off for a while, the traction control light will be off when the car is re-started but the engine light will stay on for a day or so and then go off. It is a 2010 Impala that I bought at a dealership that was a rental car. Is anyone else having this problem and did they get it resolved? The dealership can't seem to find the problem.

  • My car has 75000 miles on it and the traction control and throttle control message comes across. The pavement was dry and no gravel.Also it said engine reduced power Dealer said I need a gas pedal module replaced. Wouldn't this be covered under the powertrain warranty? Dealer says no but i know GM changed their warranty on their 2010 warranty. Can anybody help? They told me they never let the car out with this condition yet they let me take my vehicle.
  • I have a 2009 Chevy Impala LTZ with about 70,000 miles on it and the traction control and throttle control message comes on frequently. There has been not wheel spinning or wet pavement. The display will say service traction, Engine power is reduce along with the engine light coming on and staying on for a day or so. Took the car to Friendly Chevrolet in Dallas, TX and they told me that the gas pedal module needs to be replaced. Wouldn't this be covered under the Power train warranty? Dealer says no but this is not fault of mine and there has been no damage to the car to make the Gas pedal module goes out. I have had this car for 3 years this April. It’s a 2009 Chevrolet Impala LTZ. I have never had any other issues with the car. I heard that GM changed their warranty on their 2010 warranty. Can anybody help?
    On Friday 10/28/11 the card stopped in while I was driving and displayed the following messages service traction control, Engine power reduced, Engine light and the car shut off completely. I would not start again and I had to have the vehicle towed to the nearest dealer. Again the car was taken to Friendly Chevrolet in Dallas, TX. Can someone please help with this issue or advise me with the correct information regarding the car.

    I really like my Chevy Impala and would hate to have to get rid of it. But I need a car that works.
  • Replacing the gas pedal fixed mine. Since I had just bought the car (even though it had 43,000 miles on it) the dealership replaced it at no cost to me. This is an issue with alot of the chevrolets. Since I've had the work done I've had no more problems with the car. In my case Chevrolet stood behind their product.

  • I was just informed by the dealer that the APP sensor is bad in the car and that it needs to be replaced. I wanted to know if this is something that is covered under the Powertrain warranty. They are charging me $460. to replace this part. Not sure why if the part is only $127.00 why is the labor so expensive. Although I need Pritszy I still need to make the monthly payment.

    Can someone please give me some assistance with this

  • Well I'm back My 2009 Chevy Impala (Pritszy) has died again. I just had this car fixed in October and it stopped on my again this morning. This si the 3rd time this car has stopped in 3 months. My concern is that every time I ahve had to come out of pocket for these expenses. I'm not sure what the problem is this time but it started to loose power and eventually just cut-off.

    I recently had the APP sensor repalced and now this, the only lights that displayed ont eh vehicle was the check engine light. I really thought I was purchasing a good vehicle but now I have my doubts.

  • I have a 2006 chevy impala that ivonly had for only 5 months an ve bs yoyen experiencing the same exact problems im seeing that alot of you are having, I have back and forth to the dealership with this problem numerous times my car would not only reduce power but would shu t off countless times a day whether im druving on the street or on the freeway which is very dangerous having my two children in the car. The dealership replaced the throttle twice so far because thats what they were saying wthe priblemas the problem, obviously not if the problem vanished for about a week after replacing the thr soottle the second time an its now reoccuring and are now they are claiming it can be the type of gas im using and suggested I use "93" instead of "87" im yo the point where I dont know what else to do its very frustrating.
  • So a 2011 Impala LT bought used with 40,000 miles on it and we get the Stabilitrac reducing engine power message across the driver info center while pulling out of the driveway to head to church on a clear Sunday morning. I'm reading this similar problem across multiple makes and it seems GMCs' response is "Not Our Problem Man" or better yet "Change Your Fuel" really you have a mass problem across multiple lines of vehicles and this is the best you can come up with? GMC, we are taking the vehicle back to were we bought it and will have them fix the problem (in my hopes by giving us a like priced vehicle from another manufacture) but I can tell you after 2 issues with your vehicles in a row (the other one being a 2006 Uplander) I will never buy another GMC product!! And I can assure you that the next time you ask Congress for a bail out I will vehemently rally against you and anyone who votes to help you out!
  • I am having the exact same problem with my 2011 Chevy Impala. While making a right turn and a semi is on my tail, I get the Engine Power Reduced, Check Stability Control, Check Traction Control messages. I could have be rear ended or worse.

    I wanted to write and tell you I am having the same problem with my 2010 Chevy Impala. The traction control light comes on then shuts the engine down. I have had the car maybe 2-3 years....that is still new in my book. It is a huge safety concern. What happens when somebody's shuts down on the highway and they get hit. That almost happened to me. I didn't know what was going on and almost didn't get to the side of the road in time. I could feel the other cars race by me and the wind shook my car. It was very scary. I feel this should be recalled as it is a huge safety concern.
  • I'm having the same problem with my 2006 Chevy Impala 3.5L. I've had this car for 3 years and no major problems till now. This started happening around 5 months ago At first it was just service traction control light, then the check engine light started coming on and the engine would start losing power to a crawl. So took it to my mechanic and he checked it with his computer and it showed something wrong with the throttle body, after changing that the car worked well for like 5 days then the check engine and service traction control light came back on. Although the car hasn't stopped on me ever since I changed the throttle body it does have a bit of a kick in it when changing gears. I took it back to my mechanic and he cant figure out why the lights are still coming on. I used to really like GM but this is just so frustrating to deal with and a waste of money!

    Is your mechanic affiliated with one of our GM dealerships or a non-GM establishment? If the former, let us know as we're happy to follow up with him on this (we can be emailed at

  • I have a 2006 Chevy Impala. I paid $2500 this past summer at Pep Boys to repair the A/C as it had started spitting out heat instead of cool air. Before that repair the car was working perfectly. Since this summer's expensive repair many things have gone wrong. I am having to jumpstart the car every week to 2 weeks with my old old car. I have replaced the battery with a new one within the last 2 months. The alternator has been tested by a reliable testor many times & tested fine. Nothing is being left on in the car to kill the battery. There are other electric problems since the a/c repair. The electric door locks have not worked (except the driver door) since the repair except when the new battery was installed & with each new jumpstart the other 3 doors open involuntarily & never respond again. Have to manually open each of the 3 doors except at jumpstart or with brand new battery. Then of course I have to walk around & manually lock each. Again none of these problems until the $2500 pep boys A/C repair. Obviously I need to take the Impala in again but am unlikely to take it to Pep Boys & don't know where to avoid an expensive repair that will break something more expensive.
  • Also why isn't there a key hole in the trunk so that I am not locked out of my trunk until jumpstart?
