Chevy Tahoe Stabilitrak Problems



  • kmountskmounts Posts: 1
    Is anyone still having these issues? I have a 2015 Tahoe that just hit 50,000 miles has been being serviced by Chevy dealerships since I bought, and the Stabilitrak light keeps coming on and we lose our parking assist, lights flicker on and off...the last time I took it in for the full over haul and to have all fluids and filters changed and they ran diagnostics on the stabilitrak and said it was nothing, but today my engine light started blinking every time I would use the gas pedal...did this for about a mile and then it didn't do it again...I mean this seems pretty crazy for a relatively new car...
  • I have a 2013 Chevrolet Silverado 1500 LTZ. For the last few months the 'service stabilitrak/service traction control' lights have been coming on (theoretically shutting off those features) on the dash cluster as well as on the DCI screen but have noticed no difference in the vehicle handling. I took it to my dealer but when they put the scanner on the truck's DLC there are no active, pending, or recorded codes of any kind.

    Dealer said they had no idea & they would hate to have me spend $90 an hour to have their mechanic chasing a gremlin. They would hate it??? (With 33,000+ miles its out of warranty).

    I've been keeping an informal log of when this occurs as it has been sporadic. When it does happen the one common thread I noticed is the outside temperature is at or above 90 degrees. I live in Phoenix so needless to say its easy to hit that mark in the summer. As if to confirm that theory, with the coming of fall we have had some cooler temps & the warnings have not come on. But by mid-day with the temps still hitting 90+ they have been coming back on.

    So I'm wondering if some sensor is reacting to the higher heat? Or is there a module that is triggering due to the same issue? Because there are circuit boards involved (I presume) is the heat causing a faulty board connection to expand, open & separate causing what is known as a 'high open'?

    Anyone have any thoughts on this? Or have they noticed theirs is coming on in higher temperature situations?

    It will have to be diagnosed in "real time" in that case, or the situation will have to deteriorate further to make it easier to track down. The Stabilitrak isn't an actual "thing"--it's a network of things interacting--so the gremlin could be just about anywhere. You need to be reading data as the problem is occurring.

    Why don't you see if there is a highly experienced IANT member near you?

    He's got one of the best techs in the country in his general area. J. Riggle. He will find him through the iATN.
  • Anyone still having this issue? Is there a actual solution to the problem?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 58,504
    There's no one solution because there is no one "Stabilitrak" system. It's a network of modules and sensors so the "solution" could be any number of things. You could have six cars with this problem and 6 different fixes for it.

  • Fixed my 07 Tahoe today by cleaning the Mass Airflow Sensor and replacing the air filter. I have the the same stabilitrack and rough idling issues mentioned before. I also replaced all spark plugs and spark plug wires.
  • I have a 2007 chevy avalanche and I'm having the same issue misfire cyclinder
    1and I would be very interested in filing a class action lawsuit GM knew of the issue and they passed it on to the consumer that's a mess after the tax payers saved them my truck is Also out of warranty. 124.000 miles
  • I just had the same problem with my 2015 Tahoe. It happened to me on the way downhill. As soon as I applied my brake , the truck said stabilitrac and the whole truck was turning off and on. Lost control of my truck because the wheel locked up on me. It's very scary when you have your entire family in your truck and you lose control. The good thing is that I took a video of what it was doing because it did it more than 10 times. After getting back and taking the truck to the dealership and $350.00 later, they checked the truck and said that the negative cable was getting high resistance. I asked the service rep if this was common and he stated that it was. I asked him if GM Motors knew about this issue and if there was a recall. He basiclly told me that GM knows about the issue but will not fix it. Pretty stupid not to fix a 6' cable that would save lives and prevent law suits.
  • 2007 Tahoe 114k miles I have had this issue for 4 or 5 months now it has almost gotten me killed when the engine shut off and steering locked on the interstate with my children in the truck. I have had the codes read I replaced tps tune up and my oil has been serviced as it is scheduled. This happens very frequently and nobody seems to have an answer. I want an answer. I need a fix. If GM can not come up with a solution for all of these people with the same dangerous issue with the  Dash cluster warnings "SERVICE STABILITRAK" "ENGINE POWER IS REDUCED"  "SERVICE TRACTION CONTROL" then a class action lawsuit needs to be started and I definitely want to be a part of it. I work too hard for my money bought my truck out right with cash and now have a piece of crap unsafe vehicle with little to no trade in value or resale value because there is no definite fix for the issue and even the GM experts aren't able to tell me what to do to make my truck safe and reliable.

    You might check to see if there is a technician on the listings in the website I've posted (below) who is near you. These are the best of the best.

    With a car as old as yours, and with the paltry results of a class action suit (most of the money goes to lawyers), I would recommend instead that you just take it to a competent person and get it fixed.

    There is no reason this truck can't be repaired properly.

  • I own a 2011 Chevy Tahoe I purchased the vehicle used just over a year ago it now has about 93,000 miles on it . Last year I had a problem with SERVICE STABILITRAK" "ENGINE POWER IS REDUCED" "SERVICE TRACTION CONTROL lights coming on and took it to my local dealer. I cant remember the part he fixed maybe it was the TPS but there was a recall on it. It was dangerous I almost hit someone as the Tahoe would just rev up and shake when these lights came on. Now about a year later to my dismay the lights came on again and my vehicle started running rough. I was told by my mechanic that I have low compression in cylinder one which is causing my engine light to come on and that the warning lights are reading a courtesy light code. I know it makes no sense to me either! I was asked if it was burning oil which I noticed I was a half quart low between oil changes. The plug which my mechanic removed from was just covered in gunk and grime from the motor. I was told to contact the dealer first and check recalls which I did. The dealer informed me there is no recalls for my vehicle and he would look at my vehicle but the cost would be mine. I'm going to the dealer tomorrow and after reading this forum I am nervous. Its to bad cause I really like this vehicle but its not safe. I wish I would of read this forum before I purchased my Tahoe
  • OK just to follow up on my last post which after reading every other post I can say I wasn't shocked. Well my Tahoe has less than 93000 miles on it and was praying it was a warranty issue it however is a 2011 which makes it 6 years old. Yep was told its 5 year 100,000 there is no warranty and nothing GM CAN DO. It is the same problem with the number one cylinder failure which I was told they have to replace all the lifters and seals to the tune of 2,000 dollars and change. That's 10 hours of labor which is half the cost. I am stuck here I cant afford $2,000 dollars and I cant afford to be without a vehicle. It seems if there is the same problem with so many vehicles there would be a recall on it. Any advice would be greatly appreciated because I am losing my mind here trying to be calm.
