The contact owns a 2003 GMC Yukon. The contact stated that the ABS warning indicator illuminated as the anti lock brakes failed. The vehicle was taken to an independent mechanic. The technician diagnosed that the pump and the modulator had to be replaced. The dealer was notified of the problem. However, the part was not available to do the repairs. The manufacturer was notified of the problem. The approximate failure mileage was 113,389. Updated 09/02/14 updated 09/17/2014

While traveling home this morning from a ball game on nc back roads with our two children, my wife [xxx] said the brakes failed and the warning light came on and the buzzer sounded. Unable to stop, they rolled through a stop sign and pulled into a church parking lot. Upon inspection, brake fluid was dripping from a rusted brake line just inside the left rear wheel. I purchased the vehicle new and it has been in the charlotte, nc area most of its service life. Annual trips to northern Michigan with proper post trip washings should not have created this amount of rust and corrosion on key components such as the brake lines. This known problem must relate to the inferior quality of metal of GM allowed the supplier to use. The numerous failures I've read about have not been limited to the northern climates and consequently will result in numerous deaths as these vehicles age further. Answering the problem last fall with pre made replacement brake lines for customers to buy and have installed falls short of meeting GM's obligation to deliver safe and reliable vehicles. The affected vehicles should be inspected and repaired proactively by GM asap. Several years ago Subaru promptly recalled their corroded brake lines; why has GM been given a pass? information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

Rear brake line opened up causing the rear brakes to fail and empty master cylinder. Front brakes barely work. Estimated cost from local Firestone dealer to be about $600.

All automobiles in North-America should have stainless steel brake lines and fuel lines to prevent corrosion, it only makes sense and its not the end of the world as far as cost; brake failure is probably the most dangerous thing that can happen that can be life threatening. I am aware that auto manufacturers want us to replace components and make money down the line, but brake components such as brake lines have to be excluded from this.

Coming to a stop to make a left hand turn, light coating of snow on the road made it slippery, ABS braking cycled I held brake pedal down as the manuals say to do with ABS system, truck slowed ABS cycled again and then pedal went to the floor. My vehicle ended up sideways in road and thirty feet from my turn and nearly in a ditch, I then backed up to make my turn and brakes went to the floor again as I stopped to enter my road, fortunately my home was only about 500 yards from this spot. I had almost no brakes at all as I entered my driveway and parked.I then inspected fluid level in master cylinder which appeared full, from there I followed line down to the ABS module to the braided brake line and still saw no leaks, then followed the braided brake line to the brake line tubing to the frame behind the wheel well where the line closest to the wheel well was leaking fluid and it had sprayed all over the line and under carriage and frame and wheel housing shroud. The line is rusted out and burst the truck has less than 80000 miles on it and is well maintained and I bought this truck new with 8 miles on it and paid $43000 for it. This is horrendous and incredibly dangerous there was no stopping power at all, had this happened on the highway or at a busy intersection there would have been a collision.

Was backing up into parking space and applied brakes to stop. Brake pedal went all the way to the floor with no braking capability. Had vehicle towed to service facility and they reported that the front brake lines had rusted through causing fluid to be pushed out. I thought that these vehicles had a dual brake cylinder so that there would be braking capability on the rear brakes but that did not happen. Fortunately was going slow and applied emergency brake to stop. Paid repair facility to replace front brake lines. Second incident occurred on November, 2013 where I applied brakes prior to moving transmission from park to drive while on a hill. When I applied brakes the pedal went all the way to the floor with no braking capability. I determined that the left rear brake line is spewing fluid. Again, no braking capability in the front brake system. Had vehicle towed to a repair facility. I assume that the rear brake lines have also rusted through. I have read numerous incidents on internet about GMC brake lines rusting. This is a serious problem as there is no braking ability at all except for the emergency brake if one of the brake lines rusts. First, these lines should be made of materials that do not rust. I have multiple 60's and 70's vehicles where the brake lines are not rusted. Second, there is a problem in the dual master cylinder of these vehicles where they fail to work when either the front or the rear lines fail.

I was backing out of the driveway and the rear steel brake line blew out. I know the car is 10 years old, but I live in southern Virginia where we very rarely get snow and they never salt the roads.

While driving down a hill in orillia Ontario Canada, I had a sudden loss of brakes. I was able to swerve through 3 lanes of traffic and after nearly hitting another car in a service station parking lot I brought the vehicle to a stop. My brother checked the vehicle and found that all brake fluid had leaked out of a ruptured corroded brake line next to the ABS sensor under the driver side of the vehicle. Please add my name to the list of over 110 other complaints regarding brake lines which are corroded.

While traveling at a speed of 45 mph on route 47 North of yorkville, Illinois, I applied the brakes at a yellow light at the intersection of cannonball road. The pedal went all the way to the floor and I passed right through the intersection on red! the only way I could stop was to veer off of the road into the grass. The brake line that feeds the front wheels rusted through and one broke. I thought that a split system the rear would still work?

I stopped to fill the Yukon up with gas. When I turned the truck back on and pulled out of the gas station I had no brakes. They went completely to the floor. Unfortunately a log truck was coming down the road and I rolled out in front of him. Thank goodness he was able to swerve around me. He left me a few hand signs to let me know he was not happy with me. While there was no accident caused, I could've been killed due to this! I am not happy to get on line and read this has been an existing problem with the 2003 GMC's. there needs to be a recall in regards to this. My Yukon has always been serviced, inspected and well kept. There was no indication this was going to happen. I literally just had no brakes.

Was driving down my street @ 20mph, started to brake about 150 feet before the stop sign. The brake pedal went to about 1/2 to 3/4 inches above the floorboard before I came to a stop...about 5-6 inches of pedal play. I immediately traveled to my auto repair business doing a lot of downshifting and slow speed travel so as not to cause further damage or an accident. My ABS has been disconnected due to corrosion and the prohibitive cost of repairing/replacing it(approx.$1600!!). I just drive cautiously just like when ABS didn't exist. The technician inspected, he found 2 failed leaking steel brake lines...the rest of the brake lines were severely rusted. The tech re-constructed the brake lines from scratch using a corrosion-resistant alloy tubing. This tubing should not need replacing again. Tech also labored and extracted brake bleed valves from calipers. These were tiny rusted nubs. Tech re-assembled, filled and bled the entire brake system, re-tested for leaks and proper operation.all replacement lines were custom-bent from bulk tubing. The bleeding process took over 2 hours because the ABS unit was in-operative. 10 1/2 hrs of tech's time was used. The actual brakes and components at the4 wheels remain unchanged. The entire bill came out at close to $1100 but was discounted by $200 due to customer loyalty, thanks!!! there are close to 900 complaints already concerning this problem with these full-sized GM products. Yes I do live in the so=called rust-belt( cleveland Ohio area). But I do know that this incident could have resulted in an accident had it occurred at a different time and location.

On Dec. 4, 2012 heading North on the NJ tpke toward the gw bridge and got cut off. Hit the brake and the dash board lit up, the brakes were failing, pedal went to the floor. I had no breaks. Able to steer clear of traffic. Slowed the car by lowering gear and pumping brake and entered the toll for gw in a cash lane in order to get help. Able to stop car without incident but only because it was very late (9pm) and traffic was light.

I was driving on a 2 lane highway coming to an intersection to make a left turn. The left hand traffic signal arrow was green as I approach the light, approx 300 feet away the arrow light turn yellow, I took my foot off the accelerator to hit the breaks and they went to the floor, on coming traffic was still stopped when I realized I was not stopping and had to go through the red arrow light. I tried to use my emergency brake after making the turn on red, that brake also went to the floor but seem to slow me down enough so I could pull into a mall parking lot and hit the curb side to stop the vehicle completely.

Leak appears to have started within the last few days.. vehicle was purchased new and is in very good condition. I work with another Yukon owner [ 2000 Yukon XL]. he had exact same problem. Luckily I found it before any accident occurred.
