While driving the vehicle at a rate of 20 mph and started stopping and notice the brakes where going out. i had then lost brake pressure altogether. used the parking brake to get stopped after putting the vehicle into neutral. i had the truck towed to my local independent mechanic and he checked the vehicle and found all the brake lines to be rusted out, and had lost all brake fluid. upon finding this he found the majority of the undercarriage to have severe rust damage an several parts also. *tr | |||

I was pulled over by my local police department for defective brake lamps 3 times. i have gone to my local chevy dealerships and they replace the switches 4 times. i then got pulled over again so i brought it to lemay buick and gmc in kenosha wi. they replaced the brake lamp switch 2 times. when you push on the peddle and let up just a hair the brake light go inop. this is a major concern for me because i could get rear ended at anytime with no brake lights. i hooked up a light on my dash to let me know when they are or are not working at highway speeds the lights do not work 95% of the time going 70mph and slowing down to 55mph the lights don't even blink. i tried calling gmc and they said there is not a problem with the lights on these vehicles. *tr | |||

My 2007 gmc sierra has faulty abs sensors which activate at low speed stops and greatly extends the stopping distance of the vehicle. searching th einternet usenet list it seems that a good portion of gm fullsize pickups and suvs have faulty abs brake sensors which activate during low speed braking. 1999 - 2007 vehicles seem to be the most affected and include sierra, yukon, suburban, and silverado trucks. gm has known about the issue for many years and has issued a service bulletin on the issue but failed to issue recall, this leaves the owner stuck with the problem to deal with on their own. | |||

Tl-the contact owns a 2007 gmc sierra 1500 classic. as the vehicle comes to a stop and the brake was being depressed the brake would drop a couple inches and the vehicle would lunged forward. there was no warning lights illuminiating. the vehicle was taken to the dealer who repaired the front wheel sensors clean the mounting surface. the cost was $103 due to no recalls or warranty on the failure. the manufacturer was called who informed him there was no recall or warranty and offered no other assistance. the failure mileage was 37,202....mw | |||

The brake lights turn off if you press the brake and then slightly depress the pedal, although the brakes are still applied the brake lights are not on. i first noticed it while backing out of a driveway at night, and i did not think it was a safety concern until i saw my wife stop from 45 mph and the brake lights flashed and then turned off until she came to a complete stop. i took the truck to the dealership they thought there was a problem with the truck, and replaced the brake light switch. the problem did not go away. the same defect is on every truck on the car lot. the dealership wrote on my invoice that the owner presumes that when the brake pedal is pressed the brake lights should be on. duh!! *tr | |||

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. *tr | |||

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. *jb | |||
