I just wanted others to know that if you have a brake light that is coming on and staying on even when you don't push on the brake pedal and an occasional traction control error that the fix may be simply a new battery. I had the brake pedal sensor replaced, had the battery checked and still got the errors. I, on a hunch, decided to change the battery. Low and behold the new battery was the fix. For some reason the battery in the vehicle was incorrect for the car and the negative post apparently was not put on correctly. Ever since the change I have had no issues with either error and the cruise control also has not been going on and off. Just thought I would share my experience. My car is the 2008 C6 Convertible.

Great info. If by chance the issues come back you may need to do a brake pedal sensor relearn with a Tech II. I had similar symptoms and ended up needing a relearn, but if the sensor was replaced they should have already done it.

Welcome to the Forum.

If you have further issues with your brake lights, a common source of trouble is the large connector in the rear bumper.

Remove one or both tail lights on the passenger side then reach in to access the connector. Take it apart, clean it and re-connect it with some dielectric grease on the contacts.
