Has anyone experienced your 2011 Traverse having a sudden loss of power and loss of acceleration followed by error messages for both the traction control and stabilitrak systems?? This is the 4th trip to the dealer when for my car lossing all power following by the above error messages. There is no warning only ding.ding..ding and loss of power!! The dealer has said it was a sensor problem, then tried taking out the transmission and working on its sensors, and today they say it is a throttle body issue. Help! Has anyone else had this issue and what finally fixed your car?? Thank you for your help! My car has been having this issue for the past 8 months and has about 65,000 miles. Prior to this there were no big issues or problems with the car.

    jlg7,
    If you haven't already contacted Customer Service on this issue, please email us at socialmedia@gm.com with more details (including your name and contact information, the last 8 digits of your VIN and mileage, and a summary of the situation). We'd be happy to follow upon this with your dealership.

  • The same thing has happended twice now in two days with my 2011 traverse with 49,000 miles. My wife was driving to work on the freeway when the error message for the traction control/stabilitrak came on, along with a message for reduced engine power. The vehicle then would not go over 25mph on the freeway. She pulled to the side of the road and shut the vehicle off. The error message reset and then it was fine until the next day when it repeated the problem, again on the freeway. I took it to the dealer where the service guy suggested a throttle body issue, guess we'll see. Now she doesnt want to drive the vehicle.

    This past week was my 4th trip to the dealer and this time they suggested it was also a throttle body issue. However, they have also fixed sensors, taken out my transmission and diagnosed timing issues. All the fixes have briefly stopped the problem but it eventually keeps happening again without warning. Since last Friday's fix, I have not had the traction control/stabilitrak error but for some reason I keep getting a parking assist blocked error while driving but it is not causing the reduced power. In a search of the problem on the Internet, it seems this is also a problem in the Equinox. I do feel the same as your wife. I feel unsafe in my 1 1/2 year old car. I have always had Chevy cars and never experienced a problem of this nature. If GM, is aware that their cars are having this issue, they need to inform the public and get a fix out quick as the reduced power without warning is dangerous!!!

    I have also found an interesting thread on Traverseforum.com titled Service stabilitrac/service traction control. Once you read all the posts the problem is the same. ( It just doesnt mention reduced power until further down in the posts.) My dealer dismissed it and if I get the error again, Im going to strongly encourage the suggested fixes be completed. I also called GM corporate complaint offices in Detroit to start a claim. 1-313-556-5000. They will make you call Chevrolet first at 1-800-222-1020. Once you get a file #( that starts with #71), you can call corporate back and they will get involved in your case with the dealer. I think it is important to report it as it will show that it is happening to a number of people. Hope this helps!
  • ***update*** the dealer said all the codes pointed to the throttle body which was replaced under warranty. but interesting you mentioned the parking assist error because that has also shown up. I just attributed it to snow and salt on the sensors on the rear bumper, which goes away when I clear the bumper. Maybe its not the snow. Anyway well see it the throttle body replacement does the trick.

    Keep us posted on whether the throttle body replacement resolves the issue, sgowans! Hopefully the Stabilitrak and traction control issues are behind you.

    Check out the Chevy Impala forums. There you may find some guidance. This is a common problem with the Impala. Good luck.

    Thank you for the suggestion. I will try anything to get this issue to stop.
  • ***update*** well it's been about two weeks and about 500 miles since the throttle body replacement, after the traction control issue, and I'm happy to report there have been no problems. I went back and talked with the service guy who said there was a lot of carbon buildup on the backside butterfly valve and it would not open or close properly. They removed and tried to clean it first, but it still threw codes. The throttle body was then replaced and didn't throw codes. It seems to have worked.

    sgowans- that is good news! Im also keeping my fingers crossed that my issues have been fixed and I have not had any reduced power problems or stabiltrak/ traction control errors since my throttle body replacement. It has been about two or three weeks for me as well. Thanks for the update! Let's hope it stays this way!
  • Stabilitrac and traction control error along with engine power reduced hit me today for the 2nd time this week, got it to the dealership and they wanna charge $90 to diagnose but can't get me in till Monday. I have a 2011 traverse ltz with 55,000 miles. Can anyone tell me if the extended warranty will help with this or is it still covered under gm warranty. Any advice would be appreciated
  • jlg7jlg7 Posts: 16
    My extended GM powertran warrenty usually covered most of the work. After I called corporate and they got involved my issues were fixed free of charge.
  • I did purchase the extended warranties with the vehicle, how could I address this with the corporate office, would that be thru the phone number that was stated earlier in this thread.
  • jlg7jlg7 Posts: 16
    Yes. The numbers previously mentioned were very helpful. You will need to call Chevrolet corporte first to get a file number that starts with #71 and then you can go directly to GM corporate offices once you have a file started. Hope this helps!

    ************Update- 2/27/13. Unfortunately, I spoke to soon. I got the stabilitrak error and traction control error again this morning. Its back at the dealer and we are waiting to see what they say it is this time!! :lemon:
  • Well that's not good to hear. I just got mine to the dealer this morning, got a call from the service manager and was told that they were replacing the throttle body on my traverse. Just got the call that all work had been completed and that no codes came up after the test drive and that everything should be good.
    Please keep us updated, I will do the same on my side. Hopefully something gets figured out soon, I have a long road trip planned this summer.

    Well after another $1700 trip to the dealer. the diagnosis this time is rack n pinnion steering needed replacement, axel seal leak and car out of allignment supposedly caused the error messages this time. I am officially filing a complaint with my state for the Lemon Law and have complained to every agency I could today for this car. If nothing gets accomplished through that pursuit , I plan to go to Carmax to see if I can get enough to pay off my loan and get rid of this headache of a car! It seems as if everytime someone "fixes" something, 10 more go wrong! As a lifelong Chevy owner, I will never buy another GM car again. This issues with the Traction Control/Stabilitrak errors are not only problems in Traverse, they are all over the Impalla, Saturn, Equinox, GMC etc. I am convinced GM simply does not care about how dangerous this issue is. :lemon:
  • Sorry to hear the bad news, i did report to my service manager that my steering felt shaky and had knocking sound at slow speeds. I asked them to check the rack and pinion, tie rod ends and ball joints. I kinda thought that the vibrations might effect the wheel sensors and cause all the t/c and stabilitrak issue. After i picked up the vehical they said only the throttle body needed to be replace because the throttle position sensor had failed and that they could not reproduce the knocking or vebrations that i had reported. I guess i at least have it documented that the rack and pinion felt funny in case i ever have to take it back. :confuse:
