While driving, service traction control will come on along with the engine light, and they flicker on and off, and cause the car to jerk, the locks to relock, my fuel gauge to go out of place, and sometimes cause the car to turn off. I have taken my car to an actual Chevrolet dealership, but they stated that there was nothing wrong with the car because they tried and no problems were diagnosed when they used the scan tool. I don't know what to do. Some people say that it may have something to do with my transmission; others say that it is something electrical; while others say that a wire is not connecting or is touching something. One dealer stated that this is happen in all 2007-2012 Impala once they hit a certain miles.

Driving under normal conditions the vehicle speed suddenly and without warning loss of vehicle forward motion, dropping to approx 25 mph. "engine power reduced" and traction service light came on. This has happened repeatedly causing a traffic danger problem. Returned to dealer a number of tmes. Problem continues, suddenly and without warning loss of power on roadway. Extraemly dangerous in the heavy traffic conditions of sudden inexplicable loss of vehicle forward motion. Have to put on safety flashersand move to far right of roadway area..

We own the car listed above and have for over two years. We bought it at a dealership in East Tennessee. The car was previously used as a rent a car for enterprise. Not even a year after we bought the vehicle we had to replace the transmission. The biggest problem is the fact I have drove this car and all issues stated for a recall we have had a problem with. The most recent is the vehicle shutting off while driving it on highways. It's is saying service engine light mad than will say service traction control, than it will shutoff I been going 70 down an interstate and it shutoff mad about kill us. We had the vehicle checked and the accelerator pedal sensor or something like that is the problem by what technician say. I am just now starting to research the issues we have and found numerous recalls on this vehicle in which we have the problems listed above and more. Mainly the airbag steering control arm and vehicle just shutting off. I guess the best way to sum it up is they sold us a lemon perhaps but after looking at the recall list our vehicle meets the requirements for sure. Too many problems for a new vehicle. Just looking to take care of the problem before the car injures us or someone else on the highways. Hope this doesn't take long to get resolved because deaths could occur. Thanks for your time hope to speak with someone soon before it's too late. I mean I thought something major was wrong but the automd website really assured what we been thinking. Thanks for your time.

After purchasing this "one owner driven by "betty white" car on March 27, 2014 we have fallen in love with the car.supposedly purchased from the dealer were the original owner traded it in.with only approx. 34,800 miles....so much so we purchased another one...a 2014 (not new body style). I'm driving home from work at about 6:45am on a normal sunny morning in a residential neighborhood when all of a sudden I get an alert stating "reduced engine power/service traction control alert...the call lost most power and was shifting strangely...I have done some internet research and this seems to be a common problem with GM cars between 2008- and 2011...we have only made one payment on this vehicle and are currently trying to contact the dealer and waiting on a return call.......the same problem happened again last night and he barely made it to work....sometimes when this alert is not on the engine light is on...sometimes no lights at all...but this is potentially a very dangerous situation especially if traveling at a high rate of speed on expressway or something...if GM is aware of this problem...which they appear to be based on my research, there should be a bulletin or a recall available to fix said problem....I hope we do not have to pursue any further action against GM and that the dealer will make this right...this car is like brand new!!

It's apparently the standard Impala issue of the car's dash reading engine power reduced. The car has less than 100,000 miles and my I was driving home from work in rush hour when the dash read engine power reduced. I immediately phoned my husband. He insisted that I get in the right lane and be prepared for the car to die. My husband then mistakenly told me to drive to a specific exit out of the inner city before exiting the highway. Next the check stability message came on. He was like ok that's weird but lets get you home. Then the car decided to lose power brakes and steering. My hands are literally blistered getting it off the road. I guided it of the highway as he looked up the issue. Finding hundreds of these same accounts he told me to hold on a bit and restart the car. It worked and I drove it home. Had my husband not insisted I move over and be prepared this could have been a very different issue.

I was driving on the freeway at approximately 70mph, my check engine light came on. About 5 seconds later, my service traction control came on. As I kept driving, I lost power to my engine. Finally, my engine was disabled and I couldn't drive anymore. Luckily, I was able to pull over. After 5 minutes, I was able to start up my car. I replaced the throttle body, but my car still keeps doing this. This is very unsafe. GM needs to recall its cars.

I was driving home on the freeway at about 70 mph and the service engine light went on with it saying "reduced engine power" on display. About 10 seconds later I could not accelerate, the car began to start slowing down and I lost ability to maneuver the steering easily as the steering wheel locked up. I was able to pull off on the side of the freeway and I had to turn the car off and wait about 10 minutes for the problem to clear up.

Service traction control comes up and reduce engine power. Never had any prior issues with my vehicle until now. Just got it back from the dealership today and having to take it back tomorrow because the same thing occurred again. I need this issue resolved and am not the only on that has had this issue. I need my vehicle fixed and do not feel that I should have to pay for a manufacturing issue.

I have had numerous problems with my 2009 Impala. From the very beginning with only 100+ miles on it and the problems continue today. The dash will say reduced engine power and as I was going down the road at 55 miles an hour my car just shut off. I was able to get it to the side of the road and just sat there wondering what was going on. It wouldn't do anything, it was just completely off. I was about to call for aaa and tried one more time and it started. This happened again in November of 2013 as well and I was going 45 on a country rd. Again I was able to pull to the side and sat there and waited again. When this happens the car will do nothing. I have problems with my traction control, making a strange grinding type noise and bogs the car down from moving when I am trying to accelerate from a stop or trying to turn either left or right. I have had problems with my air bag lights coming on and telling me to service my air bags. It comes on and goes off and comes on and goes off. The dash light will come on and tell me to shut engine off now for low oil pressure, this has happened for 4 years, the car is 5 years old. This car was never a good car from the very day it came off the lot.

Impala 8-cyl

  • 80,020 miles
The problem started in January of 2014. As I write this I want to say that I have read all the blogs on my complaints and see that I am not alone which forces me to ask GM why is it that we all see the elephant in the room and you people are ignoring it. Suffice to say this problem is a safety issue would be the understatement of the century. When will GM step up to the plate and make these issues a priority so there customers don't have to waste time writing complaints like this one. It's really very simple my engine light is on along with the stabilitrak light as well as the car losing all power. Now if GM feels this is not a good enough reason to create a recall I fail to see what is. People just like me have been complaining about this for years and GM does nothing. Along with GM being at fault the dealerships are raping there customers while they go thru a laundry list of items they think might be the problem for these codes. I for one cannot afford the dealership prices nor will I pay these so called experts good money after bad to try and fix problems that they really have no idea as to what's causing them. I originally bought this Chevy B/C I wanted an american car for a change, man was I wrong. As soon as I fix this heap I will sell it before anymore lights go on and go right back to Honda where at least I know they stand by there cars and it runs way into the six figures before any real problems occur. I'm one of the little guys that bailed out GM and by the way were still paying taxes for that bailout. How about it GM, don't you care about us at all?

Stopped at the top of a snow covered hill. Put the transmission in 2nd gear and proceeded down the hill. The vehicle got up to about 15 mph then lost all power; engine quit, no brakes, and the steering wheel locked in place. Because the brakes were not working the vehicle gained significant speed going downhill. Not being able to steer the vehicle because the steering wheel was locked it went off the road and hit a tree. Upon impact the air bags did not deploy. As a result the driver and passenger were seriously injured. The consumer stated after owning the vehicle for a few months, the vehicle began to loose power and several messages appeared on the dashboard. All the power shut off and the consumer had to aaa to have the vehicle towed to where she purchased it. An inspection revealed the throttle body needed to be replaced. Updated 07/10/14

What happened is the vehicle traction control triggered and reduced the cars functionality and speed. It cleared itself, but what concerns me is this problem is prevalent in GM Chevrolet vehicles ranging from 2005 to 2011. It is listed many times here in your data base to your organization. Our lives and safety are involved here. Focusing on charging a fee to do an investigation is deplorable. Lives are at stake here. This should not be another american after the fact occurrence or event. What happened to proactive responsibility. These american car makers produce junk cars and the consumer constantly get stiffed with lemons. States lemon laws? nothing but american lemons are rolling off of the production lines. You think, this may be why other countries will not buy our products. There is no reliability in what is produced or manufactured and the customer service is lip service. Non - existent with these car dealers and pure sales rhetoric. Your site reads: The information you provide will be used to identify potential safety-related defects or determine the adequacy of existing safety recalls. I can't afford the repairs, pay for an investigation as well. I am not pleased with how the ball keeps getting passed or dropped. NHTSA these poorly produced weapons weigh tons. Rolling down the poorly maintained highways and streets of this country endangering us all life and limb. My vehicle has the same problem with the traction control that forces my car to brake, pull to the right and slow enough to endanger my well being. I'm truly scared and concerned here and the repairs and code lights aren't reliable. Only the repair shops are winning. The problem keeps repeating after thousands are spent to keep the car running. I need this car for work. If it cant get me there then they will come and take the junk back I am trying to maintain. Thank you

Let me try again....I was driving on the expressway, at 55 mph, when the check engine and traction control warning lights came on, along with the reduced engine power warning. I took it into the dealer, where I bought it in Aug. 2009. I can't remember when this problem started & how many times prior, because the warning lights would go out, without any reduced engine power warning or reduced power. I thought it was one of what is called a computer glitches. It was at this time when I did get reduced engine power, when I knew I had to take it into the dealer. On Nov.29,2010, the accelerator pedal was replaced......on Jan.05, 2011, I brought it back and was charged only half of the rate for mech. Diagnosis fee, because I argued so much, that the car is still under warranty, and they have not repaired the same initial problem. I left the car with them to drive, they drove it 28 miles without any problems. On Jan.06,2011, mileage was 38727, they replaced the throttle body assembly, N/C. I think it was at this time, I was told to return the car, without shutting the engine off, which is what I did. On Feb.05,2011, mileage was 39831, where they replaced a a.I.R. vent valve....I have changed living locations last spring....meaning there might be more times that it was brought in.....my memory is telling me that the both warning lights were coming on and off last year, and now more frequent, with slight reduced engine power...81000 miles

My issue was that I was four months into driving my new 2009 Chevy Impala and while driving on the highway going about 60 mph my car showed flashing signal reading "engine reduced speed" "check stabilitrack " and my check engine was on. The car then stopped accelerating and dropped to 45 mph immediately. I was nearly rear ended with my son in the car. After researching and hearing complaints about GM and how they are not taking responsibility of this safety issue and actuality charging people to fix their defect. Their are numerous blogs and videos proving this. Examples: Show over 23,000 drivers with the same issue www.youtube.com/watch"V=_hp4ngkg2bs : www.youtube.com/watch"V=iagzhyb3gho thank god it does not look like any fatalities have occurred as of yet but who knows. Please don't let someone get injured or lose their life to take notice to this. GM thinks injury or lose of life = $222. I am in contact with a law firm in hopes of a class action.
