Rusted out brake line at 72000 miles. What a disappointment but it doesn't look like I am the only one. Its a shame gm doesn't man up and correct the problem of rusted out brake lines. Luckily I was in front of my house when it failed and not running down the road pulling my 4000 lb. Boat. And yes I have read all the info online about the nhtsb investigating this problem and let gm off the hook by saying owners should wash their cars to remove the road salt that caused this problem. I guess ford and dodge owners crawl under their trucks in the winter and do this as there was no investigation on them. By the way I live in tn where winters aren't that bad. And one other thing what marketing buzz saw decided it would be better not to have a split brake fluid reservoir so at least I would have 1/2 of my system, had no brakes front or rear because of this.
2007 GMC Sierra 1500 brakes complaints
Page 2 of 2: complaints 11 to 25 of 25, newest first, as owners wrote them.
Tl* the contact owns a 2007 gmc sierra 1500. While attempting to drive forward, the brakes would erroneously active while the vehicle was in motion. The contact also indicated that the check engine sensor light activated and remained illuminated. The cause of the failures was not diagnosed. The vehicle was not repaired. The manufacturer was not notified. The failure mileage was 170,000.
I went to a local recycle business to drop off some cans. Upon entering the building at about 10 MPH, this guy motion me to stop and walked in front of the truck. I hit the brakes and the peddle almost went to the floor, but did stop. Just missing the guy that walked in front of me. Realizing that a brake line broke and that the dealership wasn't far away, I drove really slow to get there. I left it over the weekend. Monday they found that the brake line that runs from front to rear rusted and burst. $ 463. Later I took the truck home. After crawling under the truck when I got home, I noticed more brake and fuel lines with allot of rust. I applied some paint that's supposed to slow down corrosion. I'm glad I wasn't on the highway with my grand kids in the truck. Or worse, the fuel lines could break. I believe there should be a recall on the brake and fuel lines. How much would it have cost for the manufacturer to have installed stainless steel lines when the truck was built? I'm sure it wouldn't have been much. I hope nobody has to die before anything is done. Thanks for your attention.
While following other normally traveling vehicles downhill - vehicles in front came to a stop - brake peddle was fully depressed...no response...brake fully applied 2nd time...no response...resulting in a rear end collision multiple vehicles...possible total of my 2007 sierra. Damages are very extensive . Insurance to investigate gm brake possible cause....airbag deployed chest & neck injuries....many other incidents involving gmc brake systems. Need immediate the federal safety agency investigations !! This could have caused a fatality.
I have bought the truck used I have emailed gmc that I was having issue upon doing so they had sent me a phone number to call which I tried and it said it would not let me from my area I emailed them again and they did not reply. My master cylinder went out on my gmc sierra 1500 wt extended cab and I found upon replacing the master that they used a 2006 master cylinder on what they call a 2007 vehicle .. Lost the brakes completely no wreck. What they did do was send me a letter in the mail stating my bumper to bumper warranty was due to expire how convenient for them. I tried hard because I want to know did they use 06 on my 07 truck to obtain replacement parts it is important. Now a few months later I am noticing that underneath the drivers side that one of the brake lines is starting to leak I still only have 48000 miles on this vehicle no way no how should the lines have rotted out this early or corroded gmcs answer is it is out of warranty. Being on disability I will have to come up with close to 300 dollars to replace all the lines before they blow out and cause me to have a major accident which gmc does not seem to care that they have installed defective parts that prematurely fail.
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.
My 2007 gmc sierra has faulty ABS sensors which activate at low speed stops and greatly extends the stopping distance of the vehicle. Searching the internet 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. While driving less than 5 MPH, the contact slightly engaged the brake pedal and the anti-lock braking system began to activate with an unusual vibration. The failure occurred ten times when driving at low speeds on both uneven road surfaces and normal road conditions. The vehicle was not diagnosed or repaired. The failure mileage was approximately 17,000. Updated 02/03/11*lj the consumer stated the truck was repaired the dealer. Updated 03/17/11
Tl* the contact owns a 2007 gmc sierra 1500 classic. The contact stated that when applying the brakes, the brake pedal would drop a few inches and the vehicle would abnormally lunge forward. There was no warning lights illuminating. The vehicle was taken to the dealer who repaired the front wheel sensors and cleaned the mounting surface at the contacts expense. The manufacturer was called who informed the contact there were no recalls or warranties on teh vehicle and offered no further assistance. The failure mileage was 37,202.
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.
Front brake rotors are warping.
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!!
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.
Tl*the contact owns a 2007 gmc sierra 1500. While driving 15 MPH, the brakes failed twice. The vehicle has been to the dealer approximately 15 times since it was purchased in august of 2007. The dealer turned the rotors and changed the brakes and the seat belt assembly. The dealer was unable to duplicate the failure. The fuel gauge failed and the bed of the vehicle separated from the frame. The engine lifters failed to function properly as well. The failure mileage was 12,000 and current mileage was 12,100.
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.
