I have an 08 LS3, and the brake lights come on without my foot on the pedal. When you press the pedal the lights go off until you get to the bottom of the throw, you hear a click, the brake lights come back on and the gear shift releases. They remain on while driving. But this doesn't happen all the time. Any ideas? P.S. when it is working properly the click and gear shift release is at the top of the brake throw.
