If your vehicle has under 36k miles then you should have no problem getting the concern covered under warranty. I own a 2008 Trailblazer also and had the same issues. There is a sensor in the steering wheel that causes all those lights to come on. The dealer will more than likely try to flash or reset the vehicle's computer to fix the problem first. This works about 80% of the time. If after a few days the lights come back on; they will want you to bring you vehicle back in to replace the sensor under warranty. If you do have over 36k miles on your vehicle now, sometimes the dealership will still cover the problem under warranty. It's up to the dealership if they want to cover it as a "goodwill" repair.

Is there any legitmate reason for this light to come on? What would I experience at the wheel if the sensor was giving a legitimate read of a real problem?
Expert:  Shadetree mechanic replied 6 years ago.
The only reasons the lights would come on is either sensor failure or the computer is "translating" incorrect information. More than likely you would not notice anything at the wheel. The traction control system or "Stabilitrak" system controls the amount of power going to the wheels in the case of loss of traction. Much like the ABS system that prevents your wheels from locking-up during hard braking.
