2007 GMC Sierra crew (new body style) while stopped at a stop sign I nearly had a vehicle rear end me. I had my brakes depressed and noticed my brake lights were not light up. I then pressed a little harder on the pedal and then my lights came on. This new brake light where if you step as hard as you want on the brake and then let off a micro inch and it goes off. So I got home and did some searching and found that this type of problem is occurring quite a lot with this truck my thought on this is that any time the T brake pedal is even depressed just a little bit the lights should go on. I did also find it strange that the brake lights do not work with the ignition off. First vehicle I can recollect ever set up that way.

I purchased a brand new 2007 GMC Sierra 1500 pickup from lone star Pontiac Buick GMC in mckinney, Texas on 11/18/06. Only after being pulled over for speeding did I realize the speedometer was not calibrated correctly after the dealership had installed an after-market lift kit and large tires and wheels on this truck. I discovered by calling another GM dealer that because the speedometer is not calibrated correctly it causes the anti-lock brake system to not function properly. The dealership willfully and without regard to the safety of its customers sold vehicles like mine that had brake systems that did not work properly. The general manager confirmed that they have sold many trucks like this so it is reasonable to assume there are many trucks on the road now which may have faulty anti-lock braking systems. I am concerned for everyone else that purchased one of these trucks and aren't aware their brakes don't work right. The general manager told me that the speedometers can not be calibrated correctly.
