Buick Repair Questions? Ask a Mechanic for Answers ASAP
My Service Traction Control and Service Stability track lights are on. Would you be able to explain why this is happening. My car has gone for repair on the transmission twice. Can this be the problem?
Could you explain your situation a little more?What year & model is your Buick ?
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 I 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.
