Stabilitrack and Traction Control Issues

[MFarley]

I have a 2009 Chevy 5.3, flex fuel, 1500, Crew Cab, 4x4, 30k miles an a new GM Crate engine that I have had "0" problems with. Recently had both front hubs replaced. While driving to work this morning I suddenly lost power going 70mph.  The truck went into creep mode. An "Engine Power Reduced" warning came on. Stabilitrak and Traction Control warnings lit up the dash. I have researched and read a hundred different possible causes. Has anyone had this issue, took it in to a dealership and had it checked and got it fixed on the first diagnosis? If so, what was the problem? Unfortunately the Chevy dealer in my area does not have a good rep for service and the last time I went in they misdiagnosed my front end problems twice before they finally figured it out, causing me to spend 1200 dollars extra I should not have had to spend. No apologies were given. So if anyone has had this problem, and can shed some light on my plight, or can offer any realistic and legitimate info, I am all ears.

I learned something today.  Dawson GA is not the same as Dawsonville GA (home of the NASCAR Elliotts).  

 

Seems like almost any powertrain or braking error code will cause the Traction Control and Stabilitrak lights and chimes to flash.  I've personally had it happen on a '09 Silverado for AFM misfires, bad throttle position sensor, and brake sensors.  Could be a thousand different things.

 

If you subscribe to Onstar, press the blue button on your rearview mirror and tell them to run a remote diagnostic and tell you the error code number.  Or most any auto parts store will do the same for you for free.  Then you can use the 'net to track down what it could be and at least you'll have a general idea, even if you have to take it to the dealer.  My GM dealer charges $100 to scan for codes, which I try to avoid.  Just one of the reasons I got a Hypertech tuner; in addition to turning off AFM, it also reads codes.  Keep in mind, though, that some problems won't show up on a simple scanner and require a special $1200+ GM scantool to read/diagnose/recalibrate for the problem.

Without the code(s) we are only guessing. REP will tell you what the fault was and where to start looking.

Get yourself a Tech-2 or at least a Bluetooth OBDII adapter that can read engine, tranmsission, transfer case and chassis (brake) codes and data through the Torque Pro app for phones.

My truck did this to me today my abs light even came on a couple of times. I watched some YouTube videos and came across one saying a bad ground so i ran a wire to my ground from the battery to the ground strap on the firewall and it's been working ever since hope this helps
