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.

Brake pedal went to floor almost causing an accident before the vehicle came to a stop. Before the service light came on. The service light did come eventually at which time we checked the master cylinder which was extremely low so we filled it thinking that was the problem. The next day we noticed brake fluid dripping and after checking realized that at least one of the brake lines were were rusted through in several places and all of the other lines are terribly rusted and probably on the verge of leaking also. this IS a truck that we usually pull our camper with. Luckily we were not pulling it at the time this occurred.

In late october, 2013, I purchased my 2006 GMC sierra c1500 standard cab, 2WD pickup from a private owner. on or about, december 01, 2013, I noticed that the "service air bag" warning message appeared intermittently. the "airbag" illuminated symbol in the dash instrumentation area was also illuminated. this would randomly come on and go off during normal operation of the vehicle. I subsequently took the truck to a local gmc/chevrolet dealer for service of this problem. they charged me to fix the issue and it did not appear for about a week after their repair. I should have known better, as the dealership has been unable to successfully repair previous issues on other vehicles that I have had serviced there. the "service air bag" message has been on constantly since about february, 2014, as well as the illuminated icon in the instrument cluster. I have no confidence in my local dealership with their ability to remedy the situation and may have to seek third party repair for this issue. general motors seems to have no web site to assist owners and I must now glean knowledge from the internet in an attempt to remedy the issue. I can find no recall information for my make and year of vehicle for this problem, but, that does not mean that one does not exist. *tr

The driver's side seat heater randomly comes on. If you turn it off it comes right back on again and cycles through the various heat settings. It creates a dangerous distraction in the florida heat. I've taken it to numerous dealers, none of which can fix it. I call gm and they won't even consider it until I take it back to a dealer saying they will only get involved if I have taken it to a dealer within the last 30 days. One dealer told me that was a lie, there IS no 30 day requirement. This issue IS more of a distraction than texting. Looking it up online it's a common problem but gm denies it even though gm did issue a tsb to have the drivers door module reprogrammed. I had that done and it made the problem worse. A straight up safety issue. I have the same problem with a 2005 suburban and filed a complaint on that one too. Nothing came of that either so it appears this site and agency IS nothing more than a sounding board. Gm and nhtsa cannot afford to distance themselves from this. *tr

Brakes failed while coming to a stop in light traffic. Braking action reduced to approx 10 to 20 percent of normal. Driver felt a "pop" and the brake pedal went to the floor, followed by a 'service brake system' warning message. A large puddle of fluid formed under the truck when parked and a quick look under the truck showed lots of fluid from the front of the bed to the rear of the truck. Further investigation showed heavy corrosion on all rigid brake lines. All brakes lines will be replaced. The failed line powered the rear brakes. this truck IS only eight (8) years old. This could have been lots worse if the brakes failed one week earlier when I was pulling a camper through the tennessee mountains. *tr

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.

I was approaching the stoplight fletcher drive and lee highway at approximately 25 mph heading east on lee highway around 1600 edt in warrenton, va. there were four (4) cars waiting to turn left onto fletcher drive in front of me. the car in front of me came to a sudden stop. I applied the brake with approximately 2 car lengths in front of me. the brakes started to grab but then the brake pedal went all the way to the floorboard. I pumped the brakes and my truck continued to roll and then hit mr. [Xxx] vehicle at approximately 5-7 mph. I was unable to come to a complete stop until making contact with [xxx] car. I asked if he was ok or hurt and he replied yes, I am ok. why didn't you stop?? I explained that I tried. I then suggested that both of us pull into the fauquier bank parking lot and exchange insurance information. at this time, I noticed my brakes had completely failed and the truck was leaking a significant amount of brake fluid onto the parking lot (coffee can or more in 10 mins). I stated that since it was a mechanical failure on my vehicle, I would feel better submitting it through insurance. I also showed him the leaking brake fluid. [xxx]. asked why I was driving with failed brakes and I explained that the brakes had failed at the intersection, that my brakes were working properly prior to the accident and that my truck had just been picked-up from service at the dealership (country chevrolet) on monday with no problems. the dealership just informed me that all the brake lines need to be replaced and that they have corroded through and basically "exploded". a similar issue occurred with my 2003 GMC sierra in 2009, but with no accident. all brake lines had to be replaced due to corrosion. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(B)(6). *tr

My 2006 GMC sierra 1500 4X4 crewcab was running idle as I was preparing to leave for camping trip. I was checking to insure all lights on vehicle and trailer were functioning properly before departing. I noticed upon departure that smoke was coming from inside the steering column. I turned off running lights and when I tried to turn off the vehicle I found that I could not as the key was froze/stuck in the on/run position. The cab of the vehicle was filling with smoke and I could not turn the vehicle off. I quickly drove to the nearest gm dealership who was unable to help due to a heavy backlog. I was able to find a local mechanic who promptly assessed and serviced my truck. The mechanic alerted me that while this truck IS not on the recall list, the part he replaced (the ignition switch) IS the purpose behind the entire recall and that the part had failed exactly how the recalled assemblies were listed as failing. I do not know why this truck has not been looked into further for this recall but had I been further into my trip and not had a mechanic close by to get the truck to, the end result could have been far more damaging then a couple hundred dollars... *tr

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. *tr
