Brake Hoses, Lines/piping, And Fittings problems of the 2003 GMC Sierra 2500

Brake line rusted through and lost all braking capability. Luckly it happened pulling into my driveway and not on the highway! fuel lines rusted through and leaking fuel puddling onto the ground.

Complete brake failure while pulling a 10000 pound trailer in camp ground. The brake lines under the drivers side broke appeared to be corision. Truck was towed to repair location. All brake lines were replaced, cost $ 950 dollars.

Driving to work one day, a car in front of me suddenly stopped to turn left. I hit my brakes and felt a "pop" and the brake peddle went straight to the floor, no brakes. I was travelling about 55 mph so at that point, I am a 55 mph spear on wheels. I swerved to the right and drove across someones driveway and through their yard. This weekend was the city wide garage sales, and thankfully, these folks were not having a sale in their driveway or yard, or else this could have been a terrible accident. The only rust issue with this truck is the brake lines and fuel lines. If your lines rust before your body rust, then I feel there is a serious design flaw. If it was something else rusting then it wouldn't be as big of a deal. But when you are talking brake lines, it is just a matter of time before this flaw causes another catastrophic brake failure, leading to an accident involving serious injury or death. A 10 year old truck should not have this problem. I have owned vehicles that were 15, 20 years old and have never had to replace brake lines. Someones life is worth so much more than a cheaply made brake line.

I had stopped at a gas station and when I left I was going approximately 35 miles per hour when I put pressure on the brakes and the brake lines ruptured . Was able to get to a repair shop and they said that the lines had rusted through. All lines had to be changed,.

The vehicle was taken to a private mechanic who inspected the brakes and noticed there was a hole in the brake line that caused a leak. The mechanic stated that he needed to replace the entire brake line. The manufacturer was not notified. The failure mileage was 99,075. The VIN was not available.

Was driving down road at speed limit, hit brakes, rear brake line burst (was severely rusted). I was unable to stop vehicle and proceeded through a red light at a busy intersection with my 2 year old on board in his car seat. How we both made it out of that incident unscathed is amazing. I was unable to stop and had to pull off to the shoulder and hit the parking brake. It took my son a good 2 months before he was able to rid himself of fear and anxiety due to what happened.

Took truck to dealer for other work and they reported to me the line was leaking and about to rupture. I have 2 Jeep products , both in the late 80's with original brake lines and they are fine. You would think that a "younger vehicle would be up to the task of lasting longer than 9 yrs. I've owned older cars and trucks and have never seen anything like this, even my 1964 chevy c-10 didn't have this problem and I sold it in 1991 . A CO-worker bought my old chevy and at the 30 year mark for it, the brake lines were fine. I believe that along with the manufacture the government should be held accountable also, they allow this subpar equipment on the roads and highways to carry our kids and families, do you think obama's kids would be subjected to danger in this manner. If the director of NHTSA had a failure of this caliber he or she'd be all over this demanding and enforcing a recall .

Brake pedal went to floor at 10 mph from failed brake line, due to excess corrosion on brake lines.

Brakes failed to engage, I took it to a gm dealer and upon investigation found a corroded brake line that had failed. As they investigated further they found that all the brake lines were corroded and had to be replaced. I have been a mechanic most of my adult life and have never ever heard of corroded brake lines on a 9 year old truck. This is insane I would like to know why there hasn't been a recall on this very important safety issue????? what happens when someone is killed?????? I have no problem taking this to the supreme court. When does money take the place of the most basic safety feature known to the american auto makers???? I want everyone to know that this is known problem with many gm auto's and trucks that everyone is aware of and nothing is being done to correct it!!!!!! how do they sleep at night?.

The contact owns a 2003 GMC Sierra 2500 hd. The contact stated while driving 35 mph and applying the brake they extended to the floor. He also saw smoke underneath the hood. He drove into a parking lot, checked under the hood and notice that the brake line was broken and sprayed fuel on top of the exhaust. The vehicle was driven to his home. The contact notified the dealer who stated there were no recalls related to the failure and the vehicle will be repaired at the owners expense. The manufacturer was not notified. The failure mileage was 83,000.

Corroded brake lines.

I was traveling down the road at approx ~30 miles an hour approaching an intersection with a red light. I went to apply the brakes, the pedal depressed with no resistance and no braking response. I applied the brakes harder, with pedal all the way down and received light brake response, enough to stop the vehicle just short of the intersection. I took the truck to an ase-certified napa auto center, where the diagnosis was that the brake lines were completely corroded, as well as the emergency brake cables. The corrosion of the brake lines/cable resulted in significant loss of brake fluid, and rendered the emergency brake useless. The total cost of repair is upwards of $1800. 00 there was no advanced warning of this failure--no warning lights appeared before or after the failure. This could have been catastrophic and feel that this is a design, assembly or materials flaw that puts public safety at risk.

The brake line on my 2003 GMC sierra ruptured from corrosion between the anti-lock brake controller and the right front tire. The rupture was right in front of the fire wall. I was driving the truck and heard a release of what I thought was air from air brakes, this occurred on two occasions less than a minute apart. I new the noise was from my truck but I wasn't sure from where. I put the truck in park at a traffic light and walked around the truck and determined I didn't have a low tire. With the truck still in park I pressed on the brakes, which led to the brake line rupturing. I saw steam from the brake fluid that sprayed onto the manifold. I was able to return safely to my home, which was less than two miles from where I stopped the truck. I visually inspected my brake lines and saw corrosion in the area of the brake line rupture.

I was driving my '03 GMC Sierra 2500hd on a highway at approximately 65mph, when I had to slow down, to avoid hitting a vehicle slowing down in front of me. I stepped on the brakes, no harder than I normally would, and the pedal went all the way to the floor, with very little to no stopping action from the brakes. I was able to slow down by downshifting the automatic transmission and using the emergency brake to stop, while pulling onto the shoulder. My truck had to be towed to a repair shop, where it was determined that the rear brake line along the drivers' side frame rail had ruptured due to corrosion. My emergency brake assembly also had to be replaced due to excessive rust on it, as well as defective brake shoes. The total cost to repair the brake line came to approximately $450. 00, and the emergency brake replacement came to around $900. 00. The rest of the brake lines are also very corroded, and should be replaced. I was quoted a price of $1,450 to replace the remaining brake lines on the truck.

On Nov. 14 2008 my 2003 GMC Sierra 2500 hd 4x4 brake lines failed. The GMC dealer service consultant stated that 1 of my forward lines had failed due to corrosion and that 3 more lines needed to be replaced due to corrosion. That they would fail at any time. With only 56,292 miles on the truck and not living on the gulf coast I was surprised to say the least. I had to pay $ 1209. 69 to get the lines replaced at the dealer.
