2003 GMC Yukon Denali: brake failure

Filed Jul 28, 2017 · Brakes · KY

Brakes lines rusted which LED to catastrophic failure of brake system. Repair cost $1,000. There are multiple thousands of complaints regarding this type of brake failure in this make, model, & year. This should be a mandatory factory recall. Someone is going to die because gm is not being forced to fix their faulty equipment. My vehicle was in motion and when I depressed the brake pedal the pedal went completely to the floorboard. I was driving straight ahead in moderate city traffic & narrowly missed striking the vehicle in front of me on a city street. My master cylinder was completely empty of brake fluid when examined. I was traveling 25 MPH and my vehicle has 110,000 miles. (the next page wouldn't allow me to enter the speed & mileage information where it was requested)

Brakes failed while driving on city street with no warning could not stop at red light. Immediately pulled over and noticed brake fluid leaking from left side of vehicle from a broken brake line.

My daughter was driving and when slowing down the brakes failed to work. The vehicle was not able to stop and collided with the vehicle in front. Luckily nobody was injured in this collision. After inspection, I noticed fluid on the ground at the rear left (driver's side rear), and looked under the vehicle to see where the fluid may be coming from. I saw that there was fluid coating a large area of the underbody, and also see the brake line attached to the frame as wet and rusted. I have pictures saved as a reference.

I was traveling down a city street and went to stop at a red light. I applied the brakes and the pedal was very soft so I pushed a little harder and the pedal went to the floor. I had to swerve into a gas station parking lot to avoid an accident and apply the emergency brake to stop the vehicle. I crawled under the vehicle and saw that there was brake fluid dripping from the floor and the hard lines under the driver side floor. It is getting taken to the dealer tonight to have the issue fixed. Please make gm responsible for this issue and to pay us back as this is a very dangerous problem and very expensive to fix. If I would have hit the brake a couple seconds later I would have missed the entrance to the gas station and rear-end the vehicle in front of me.

Rusted brake lines caused immediate loss with no warning. Loss of brakes were catastrophic with only emergency brakes available. Car came to a controlled stop on median but could of been much worse given no other vehicles in the vicinity.

All of the brake lines are completely rusted out. My wife had a complete brake failure while driving my daughter to school. Brake line over frame leading front to back failed and completely emptied the master cylinder of brake fluid, result car would not stop. This must be made into a recall, as the possibility of a major accident and loss of life is very probable.

I have a 2003 gmc yukon denali with approximately 12k miles when the brake lines corroded and caused brake failure. No accident,no injuries . It seems like the whole undercarriage is corroding. Vehicle was taken out of service to be repaired. Seems to be a safety issue of importance.
