    I bought my 2008 Impala on December 15 2012 and exactly 3 months later is the first time the engine power is reduced light came on, I took it to the dealer and the said it was the throttle pedal assembly so I had it replaced, two weeks later the light came on again. This time they said it was a pinched wire and that although it wasn't covered under warranty they would replace it as a courtesy. Then in June I was involved in an accidents and the light came on again, this time they said the computer was jarred so they rest it. Then yesterday I was sitting at a stop sign waiting to turn and when I went to accelerate my car stalled in the middle of the road and a car coming off the bridge almost smashed into my. I had my 3 small children in the car with me at the time so it was very scary so i decided to turn around and go home in which it stalled out on me 4 more times within 5 miles. I am a single mother of 3 and dont have all this extra money to be putting into problems with a new car that you would think should be covered under warranty. This issue is obviously endangering alot of people, when is something going to be done
  • Jessielee, you should send a message to rmasco1 the GM customer service rep so they can get more documented info for this problem. :)
  • Correction, that's mrasco1. Sorry :)

  • I just got the service traction control and reduced engine power messages on my way to work this morning. Fortunately for me, there was no noticable reduction in speed as others have described. I have a 2011 Impala LT, bought used approx two months ago from a local dealer with just over 40K miles on it currently. Since this seems to be a known issue with this vehicle, I will take it back to the dealership and ask that it be repaired at no cost to me.
    I also have noticed an issue when using the cruise control that the vehicle will pick up excessive speed when the CC is engaged and traveling down hill....up to an beyond 20 mph over the CC setting. Since this seems to be a throttle/sensor issue, I'm wondering if it could be related. Have any of you experienced this with the CC as well?
  • Good morning ajaywill,

    Christina, my coworker, has received your email and if she hasn't already responded to it will be doing so soon.

    All the best,

  • I experienced the same issue about a week and a half and we where told it was the starter. however we replaced it and i haven't had a issue so far please try that and see if it helps any. One thing for sure they need to do a recall on these issues before someone is hurt.
  • It is your accelerator pedal assembly sensors. I had the same problem and had the throttle body assembly changed and that did not fix the problem so I took it back to the mechanic and it was the accelerator pedal sensors. They are 2 sensors that work together and relay an incorrect message for acceleration. I had it fixed in February 2012 and have not had a problem with that since. I hope this helps you.
  • Hi I am also experiencing this problem on my 2010 impala . I have close to the same miles as well 50,800. Did the dealership cover this under your powertrain warranty ? How much did it cost you out of pocket ( if you don't mind me asking ) ? Are you still having problems since this post ? Did they say why this happens , is it a recall ? Please respond I'm trying to get an idea of what I should look forward to when getting my car fixed this week. Thank you so much

  • If too many of us that are owners of chevy Impala have the same issue why is it not considered a recall. I am a 2 week owner of a 2009 chevy Impala and my car shut down on me while driving on the highway it was the grace of God that my children and friend that were in the car made it safely to a nearby gas station. Thanks to my quick fast action to have it cost to the access road. The car would not start I am so disappointed in the what I've read here and experiencing it .. what will be done about this issue.. concerned owner..
  • I am a 2 wk owner of a chevy Impala 2009 I experienced the same thing this afternoon the car shut off on me while driving. I had my children and a family friend in the vehicle on our way to chuck e cheese. I had to think quick and fast so we would not be in a car collision. I am totally disappointed at all the reviews that are the same and it is not a recall. This has become a safety issue. I have anxiety thinking when will the car shut off again without moment notice because of faulty sensors.. I received traction control and reduce engine power and service throttle starting disabled. OMG i do not want your standard reply to reach out to you guys take to nearest gm dealer .. can we get a recall.... I think I should have stayed with non american cars...
  • I too have experienced that today. Plain and simple this is a safety issue that GM is aware of based on this blog and forum. I was on Highway 401 today heading to Trenton, ONtario. I was doing 100kms and it went down to 40kms in a matter of minutes. I was very lucky that there was no one behind me. My screen read traction control and reduce engine power. I brought it to my nearest GM dealer. The young lad was very nice. Took all my info, etc. Called me back with the amount for the repair. I asked if there was a recall. I thought it was strange. So I searched on the internet and stumbled across this site. I called GM immediately 1-800#. They are investigating with my dealer. I explained to the girl that this is dangerous and should be recalled. She said she would get back to me by Friday am. I think it maybe just brushed under the rug. I hope it's not a standard response that we get. It's very dangerous and someone is going to be hurt because of this because it happens so suddenly. :confuse:
  • Well I got my call back. All the dealership will do is give me 10% off my bill. Head Office - thought that was a solution. They just don't get the drop speed on the highway. So I called Transportation Canada they will investigate but apparently I was the only one that has put in a complaint about this issue. Which I find odd since there is so much on this blog. Since there is only one report - they said it was interesting. So they said they will follow up some how but unless there is other cases documented I don't feel anything will come of it. If someone did hit me from behind - I think more would be done. Unless until someone is hurt - nothing will be done. :confuse:
  • I just experienced this last night in my 2011 Chevy Impala LT with 47,000 miles on it. Is anyone having luck getting this known issue fixed? Is it covered under the powertrain warranty? I just bought this car less than a year ago and don't have the money to put out for these kind of repairs when it's a known problem and a quick google search pops back many links to this kind of issue with Impalas. Just looking for all I can find before arriving at the dealer tomorrow morning first thing!
  • Mine was not covered under warranty. If it was the transmission yes. Warranties might be different in the states. I called GM only a 10% reduction. It's alot of money anyways. Had to cancel a trip but that's life. My car is my income - sales person. Unfortunately no one seems to understand the safety issue in this. If I were you - I would call General Motors head office and complain. Also, call transportation highways - more complaints the more apt they are to investigate for recall. Also a letter to the better business bureau. All documentation helps. I got the feeling if there is no one getting hurt. There would be nothing done. :sick:

    I own a 2009 Chevy Impala.Last night while driving over 75mph on I-95, the service traction control system message and reducing engine power light came on. I was traveling with my mom and three young children. I began to panic, but Thank God I was approaching a rest area. I purchased this car over a month ago, and am very disappointed. My previous car was a Mitsubishi,which I had for over six years before encountering major problems. I'm very grateful that we were not plowed over by on coming traffic. I was shocked to find all the complaints and that GM has not rectified the issue.

  • 2009 Chevy Impala owner. Car ran good for the first couple of years I owned it. Then just recently it started throwing all four of these error messages. I was able to avoid a severe accident when the car totally died going 65 MPH on the interstate. Sat with it for 15 minutes and it started back up. After reading several messages and similar stories it leads me to believe the only reason Chevy will not issue a recall notice is due to monetary reasons.

    As I read through some 19 pages on this site and several other posts on other websites, it's evident Chevy is raking in some serious dough on this fix. If you don't believe me, simply go through the posts on here and add up the amounts people have kindly posted. Just imagine how many people don't bother to look issues on the web, coupled with how many people don't even have internet and multiply that by *5. Seriously GM, get your crap together. This is a disaster waiting to happen. I bet if one of Upper Management had a loaner Impala and this happened to them, they'd take their customers a lot more serious. Simply Frusturated...
