Why does the traction off and security light come on your Buick Riviera?

The traction off and security light on a Buick Riviera may illuminate due to issues with the vehicle's traction control system or the anti-theft system. The traction control light indicates that the system is either turned off or detecting a problem, while the security light suggests a potential issue with the vehicle's ignition or key system. It’s advisable to check for any diagnostic trouble codes with an OBD-II scanner to pinpoint the exact cause. If the lights persist, consulting a mechanic for a thorough inspection is recommended.
