Had no message when the wife and I got home from the gym. Went from one parking space 25 feet away to the pull the hummer in front of the garage and the serv stabilitak light came on. I believe the dash said traction failed or something to that affect. Can this just be reset with the OBDII? The car isn't making any weird noises when driven. About to scoot up to the advance auto for some spark plugs as well. I'm on my test drive week and I know the wife really wants this car but damn things can't start so soon. The radiator is getting replaced Monday by the dealer. Thanks!

 

Went out to go to the store after and the light had cycled off. Smh...... guess I'll have to watch out for it.

 

One possible cause is a bad electrical connection to the Transfer Case actuator. When that connection gets wet and cruddy, it will kick that message to the DIC. Crawl under and check it/clean it with electrical contact spray, make sure it is completely snapped together.

There are other possible causes, but do the easy stuff first.
