Have Vehicle scanned For Codes--(bcm)This Should Get You To The Problem Area---Then You Have The Option Of Fixing It Yourself, If You Have Tools And Skills.

{: ) The two triangles you saw is for the StabilTtrak system,, sometimes called the traction control indicator. When you see a spanner beside it, it means the system needs servicing.
StabiliTrak will turn off automatically if a problem is detected in the system. For vehicles without a DIC, the StabiliTrak light and the StabiliTrak service light will both come on. If the StabiliTrak service light does not clear itself after restarting the vehicle, you should see your dealer for service.

Stabilitrak uses information from wheel speed sensors. I would have the stabilitrak system codes pulled up to see if any wheel speed sensors are 'locking' up making it seem like you are sliding or locking brakes up, when it is not actually happening. Or, it could be a bad stabilitrak module. Not sure, without seeing if there are any codes in the computer.

Good luck on this repair.

Had same problem, went to work everything was fine, then got in vehicle getting ready for lunch......no power steering and service stabilitrak light came on. End result was power steering motor needed replaced. Motor controls the power to the rear wheels along with the power steering.

I would advise to take it to a shop you trust and let them scan your vehicle for trouble codes. From there they can give you an idea as to why these messages appeared. : )

You need the system scanned with a special tool to determine the fault.

It's telling you your stabilitrak system is not functioning properly. Sensors in system are failing and setting service light. You need a GM dealer to diagnose system.
