Ok, the traction control & stability is a part of the anti lock brake system When these lights come on there has been a failure code set in the computer for a circuit failure.
This can be a sensor problem sometimes or a calibration change for the computer.You should have your local GM dealer check these systems for failures.These 2 systems work together through the EBCM (electronic brake control module).
If am understanding correctly this is a brake problem? And if so do I need new brakes? Not so smart with cars.
This is part of the ABS (anti lock brake system),but I do not think you need new brakes .This is a fault within the computerized vehicle traction & stability control system.A scan of the computer must be done first to see what the failure is.Here is some GM info that takes care of this problem a good bit of the time.
