Brake Hoses, Lines/piping, And Fittings problems of the 2006 GMC Sierra

Total brake failure while in motion. Corroded brake line ruptured causing immediate loss of all fluid. Had this happened 5 minutes earlier, I would have been on a four lane highway in bumper to bumper christmas traffic. At 70 years old I can only imagine how catastrophic an accident my reflexes would have generated. The fluid sprayed on the hot engine creating a cloud of smoke. I was afraid the truck was on fire. The fluid cooked off the engine as smoke and again luckily there was no fire. Now after extensive repairs, I am very nervous behind the wheel of this vehicle. This very dangerous situation with corrosion should be addressed as blogs on the internet indicate this dangerous issue has been ongoing for quite awhile. I have attached the invoice of the repairs required. I was in the drive through of a mcdonalds and had placed my order and was pulling to the window to pay when the brakes failed. Luckily I was only moving slowly at that time, thus able to avoid injuring anyone or damaging any other vehicles.

Brakes failed at highway speed, brake pedal went to the floor with very little braking. On investigation, brake oil would spray from the brake line under the truck.

I went to put on my brakes, I first started to stop then my brake pedal went all the way to the floor. I hit a vehicle in front of me. The collision shop that I had it repaired at said the brake lines were rusted. After further investigation I read a lot of complaints about this same defect in chey and GMC trucks.

Without any warnings when attempting to come to a quick stop brake pedal went to the floor and had no braking power. Avoided crash by driving onto a lawn. I have found that all the brake lines where they are attached to the frame in a plastic support under the drivers door have rotted through. Contacted GMC with no success just informing they are aware but no re-calls.

There is no warning the pedal goes to the floor and you don't stop. I had a 5th wheel trailer hooked to my 2006 GMC 2500 ext. Cab long bed Sierra p/u with 62,459 miles on it. I was able to stop it with the trailer brakes and a scratch on my front bumper from a tractor trailer that was in front of me. I have owned over 200 cars + trucks since I started driving. I do all my one work on them and I never had a brake line fail, I will be 70 this year. It is ridiculous for an 8 year old truck to have rusted brake lines to fail. The worst part of this is that nobody notified the public that this was a problem when they GMC knows about this problem. I found a garage that fixed the two front lines. So we could get home. Then I inspected the other lines and ordered the complete set of stainless steel lines from ebay, when I removed the old lines they all were rusted at hidden spots two were close to failing. Why do they have to wait for some one to die before they notify the public there is a safety problem. This is GMC and our government (NHTSA) failing the people.

Applied brakes when on a downhill on ramp to merge into traffic. Brake pedal went to floor without slowing vehicle. Had to swerve off road to avoid a collision . Had truck towed to dealer to repair rusted out brake lines $1750. 00 est. Was told fuel lines also looked rusted $700. 00 est.

Brake line blew out.

Drove from baltimore, MD to cleveland, OH. Parked, the next day attempted to drive and brake pedal went to floor. Brake line on drivers side toward the rear had rusted out, had to have truck towed and brake line replaced. In Dec. 2014, one year later, truck was parked for 4 days in drive, went to drive brake pedal to floor again, had to have towed, 4 lines replaced.

I bought a 2006 Sierra denali with 65000 miles on the truck in may of 2013. I lost my brakes and almost rearended a man pulling into his driveway. I also had my 3 kids and my fiance in the truck with me. I took my truck to robertsons GMC in wareham,MA and they told me my brake lines were completely rotted as well as my frame. I also had a extended warranty which did not cover it because it was a pre-existing problem. I just don't understand how gm can get away with all of these frame corrosion and brake line corrosion problems without having to fix the problems with there trucks. I have researched alot on these problems and it seems like no one is holding gm responsible and making them fix the corrosion problem. I think they should have to fix the problem like Toyota did when they had frame problems so that they can stop producing vehicles that dont last 10 years without rotting away.

Driving the truck in my driveway with a landscape trailer attached, applied the brakes and the pedal went to the floor. One of the brake lines failed due to corrosion. Had to have all of the brake lines replaced.

When I went to start the truck in the morning, I put my foot on the brake pedal and it went to the floor. Got out and saw the brake fluid on my driveway. Examined the truck and found a steel brake line had rusted through and others had significant rust.

Tl * the contact owns a 2006 GMC Sierra. The contact stated that the brakes malfunctioned while attempting to stop with the illumination of the check brake system warning light. The vehicle was taken to the dealer who diagnosed that the brake line was leaking due to corrosion and as a result, the brake lines would need to be replaced. The manufacturer was made aware of the failure who did not offer any assistance. The vehicle was not repaired. The failure mileage and current mileage was 69,000.

Truck has had an undercarriage rust issue at least since 2007. The fuel and brake lines must be replaced and the frame and suspension are deteriorating.
