My 05 EC had the auto headlights and my NBS 07 EC also has them. Frankly I got used to them and actually like not having to worry about turning my lights on or off. You can always turn the knob to the off position.
I've tried everything...The manual off function, the parking brake, the dome switch...still not having any luck. I had a colorado with the same feature and the manual off function worked. Anyway,i'll be checking in from time to time, so if anybody finds anything out please let me know.
