Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Hard brake lines have completely corroded and brake fluid flows profusely from the corroded lines. Brake pedal goes to floor and vehicle is unable to stop. Had to put into neutral and use parking brake to avoid an accident. GMC service department is unaware of any service bulletins or kits to replace defective and corroded brake lines on these truck and SUVS.

In Aug 2005, the ABS light on our 2001 GMC Yukon with 51K miles came on and there was a grinding noise (the pump) underneath the driver's side which remains on when the vehicle is turned off. The ABS fuse must be removed to shut off the pump. Our local GMC dealership repaired it for $1100 ($870 for the ABS module). In Sep 2009, the ABS failed again at 91K miles. Our GMC dealership helped cover the cost of repair by covering the cost of the module. We had to wait 2 months (Nov 2009) before the vehicle could be repaired because we were told that the module was being redesigned to fix these problems. In Oct 2014, the ABS failed again at 138K miles. Our GMC dealership put us in contact with GMC customer service with the hope that GMC could assist in covering the cost of repair. After several frustrating phone calls with supervisors, we were told that the vehicle was too old and therefore GMC would not assist. During these phone calls GMC stated that there was a recall for the vehicle in "salt-belt" states but not California. Obviously the ABS module is defective as a relative with a similar vehicle (Chevy Tahoe) had the same issue with the ABS module. In searching the internet, we found a company that states that they can repair the module for under $100 and guarantees the repair for life. If they can do this, why can't GM make the necessary changes to the ABS module and give customers the peace of mind that the vehicle will be safe. Hopefully the NHTSA will use this and similar complaints and force GM to issue a recall on the ABS module.

Brakes were weak, almost to floor so the car was towed home. While slowly backing the car into driveway the brakes failed completely. Stepped on emergency brake and intermediate cable broke. The E-brake cable failed because of rust and the brake lines to the ebcm where they go over frame all failed. The only part on this car that has rusted beyond anything normal are the brake lines. Unbelievably rusted! when the brakes (E-brake and both lines) all failed the car rolled out of controlled into a tree. The rear hatch glass shattered and I had a sore neck for 5-days. This is apparently a common problem to this car where salt is used. The brakes started to go weak (1-line must have failed) as my wife approached a toll booth, only luck prevented a catastrophic event from happening. I can't believe we were not notified or the car was not recalled! GM and the NHTSA shame on you. You knew of a safety problem and have done nothing. GM stating that you will still have brakes if the line fails is a weak argument, you have to press much harder after the first line goes and the other line is ready to fail. Guess what happens, no brakes. Please have a GM executive drive one of these death traps and hit the brakes hard. The last thing that should rust are the brake lines. A little common sense goes a long way.

When exiting my driveway I went down the street to the stop sign, when I applied the brake the peddle went to the floor and the truck did not stop. It was good that I wasn't going faster. When I took my truck ( youkon ) to the repair shop I explained the issue to the repair man. I got home and he called me back and asked me to return to the shop to take a look at the trucks problems. When returning to the shop the truck was lifted up and he showed me the brake lines and the gas lines that were corroded and needed to be replaced as soon as possible. He also explained the time and labor involved. I was surprised of how much labor and time was involved to repair these issues. He said the cost including parts and labor will be about 2,500. To 3,000. Dollars, that is if he didn't come across any other problems.

I was driving locally, when I used my brakes to slow down as I was approaching a red light I did not have properly functioning brakes, pedal went to floor, I used emergency brake this prevented me from hitting car in front of me. This occurred in August,2012.brake lines were determined to have rusted out, brakes failed, a $444 repair was needed. In November 2013 a similar incident occurred with my son driving. This resulted in a $ 1111 dollar repair bill. And today July 8 2014 while backing out onto street another brake failure occurred bill to be determined ? updated 3/18/2015

I was traveling at approximately 35 mph when the car in front braked suddenly. I pressed the brake pedal quickly and firmly to slow the vehicle, and the brakes worked normally. A half mile or so later, at an intersection, when I applied the brakes gradually, the pedal was soft and went all the way to the floor, only barely stopping the vehicle before it entered the intersection. I drove the vehicle home (about a mile) slowly and cautiously and inspected the brakes and found brake fluid coating the underside of the vehicle and what appeared to be rust or corrosion on the brake lines where they crossed the frame near the driver's side wheel axle.

Parking brake will apply itself and will stay engaged until it decides to release, or until the pads and metal shoe is worn out or catches fire from the extreme heat, if you apply it, it may stay engaged and you won't know it, until it is to late to do anything about it, ,there are thousands of complaints online that has been reported to dealerships, and to GM but they have done nothing.

Pulling into the driveway under normal, dry conditions, the brake pedal went down to the floor, and the brake light on the dash illuminated. We came a few feet from crashing through the garage door. This was a result of the driver's rear brake line springing a leak with no warning whatsoever. The affected part is the formed metal line that is attached to the top of the axle. It appears that the brake line just rusted completely through. It is likely that all other brake lines could be affected in the exact same manner.

While applying the brakes to stop at an intersection, the brake pedal went to the floor on my 2001 Yukon. A severely corroded brake line leading to passenger side front brake failed. Point of failure was at the center of the vehicle under the radiator. During removal of the failed line from it's mounting clip on the vehicle frame the brake line leading to the driver's side front brake was bumped causing it to break as well. On closer inspection it was determined that all brake lines were severely corroded to the point they were ready to fail and all lines required replacement.

I was driving my Yukon in rush hour traffic when I found it necessary to attempt a panic stop. I pressed on the brake pedal and felt somthing give way and the pedal went to the floor. I attempted applying the brakes again and again the brake pedal went to the floor. I nursed the vehicle to a parking lot and looked underneath and found brake fluid dripping from the frame on the drivers side just before the rear wheel. I inspected the brake lines and found them to be very corroded and the one line leading to the rear brakes was split open. I have since replaced the brake line from the ABS unit under the drivers seat to the junction near the spare wheel. I have inspected the other brake lines and found they are corroded also.

The contact owns a 2001 GMC Yukon. The contact stated that the brakes failed. The contact was able to stop the vehicle by using the emergency brake. The contact took the vehicle to the dealer where it was determined that the front driver's side and rear brake lines failed because of rust. The vehicle had not been repaired. The failure and current mileages were 200,000.

Stepped on brakes in a panic stop. Blew out rusted brake line near front of car. One by one, all of the steel brake lines are failing due to rust. I just blew the steel brake line at the rear of the car near the differential. The ABS sensors have been replaced twice due to corrosion and they ABS pump has been rebuilt. The parking brakes on this car have been replace 4 times and have never worked correctly.

Brake lines failed due to rust while driving on a back road. Lucky for me I was not on the highway yet and was able to use the emergency brake to stop. After looking into the problem, it was discovered that all of the lines were at the point where they need to be replaced.

Driving vehicle at approx 45mph, came to stop at red light and brake pedal went completely to the floor. Pumped the brake pedal again and nothing. Down shifted transmission to slow down and pressed the emergency brake to come to a stop. Pulled over to the side of the road, lifted the hood no brake fluid in rear section of master cylinder. Noticed brake fluid dripping under the front of the drivers door on the ground. Had the vehicle towed home and looked under the vehicle and the brake line was dripping fluid. The brake lines are completely rusted and the frame is really rusted. Just got the vehicle out of the GMC shop for routine service. Can't figure why they didn't notice or at least tell me that I might have a problem.I called them and advise what issue I was having. They advised that GM would not cove the issue and $1300 would maybe cover the line replacement plus. I am not happy. Worked hard to buy this vehicle and now that I am retired from the military I really do not have the funds to replace the lines and do something about the rusty frame.

Brake system failed while driving. Brake pedal immediately went to the floor while driving at about 35 mph. Pumped brakes to get slowed down and eventually stopped. Exited vehicle on drivers side door and found fluid puddle under the drivers side of the vehicle. Upon pumping the brakes while stopped, I noticed brake fluid squirting out under the drivers side door. After towing the vehicle home, I have confirmed a severely corroded metal brake line has rusted through and broken open.
