While approaching an intersection I applied the brakes the pedal went to the floor ABS light came on and the was total brake failure. Guided the vehicle off the road and had it towed to the shop. They found rusted brake lines at the ABS valve along with a rusted backing plate for the valve. In order to improve vehicle safety the lines will all be replaced with stainless steel so this doesn't happen again. This is a very poor design since a single failure should not cause total failure of a supposed dual breaking system.

Total brake failure while stationary and engaging drive mode in driveway. Brake pedal went to floor. Parking brake also soft and ineffective but restored normal condition shortly thereafter.. No brake or ABS system service alerts or fault warnings prior to failure. 'service brake system' alert present after failure. No obds codes present. Suspect brake line corrosion. Approximately 170,000 miles. Recent tire/brake/alignment inspection revealed no issues. This is a very clean, "new to me" used vehicle with an excellent record of service. Had just completed a trouble free 2400 mile interstate road trip.

There is a recall #05068 that describes exactly what happens while driving my car. It occurs every time I drive my car, every time I accelerate and brake. (2003 gmc yukon xl). However, gmc claims my car "isn't effected" and they refuse to fix it. My issues are 1. Getting dangerous, as the car bogs and won't accelerate without a period of hesitation and then it gives too much acceleration which can be bad if I'm on a slippery surface. Also, there is a common problem on these vehicles which is another problem I am experiencing: 2. My ABS kicks in randomly, even if the pavement is totally dry and clear. Apparently, this is caused by a corroded mounting surface for the front wheel speed sensors. The corrosion builds up causing excessive gap between mounting surface and wheel speed sensor which causes a loss of wheel speed sensor signal. When the ABS module sees the loss of signal it thinks the vehicle is sliding out of control so it will activate the traction control or ABS. Description from recall #05068: certain pickup trucks and sport utility vehicles may experience unwanted antilock brake system (ABS) activation. This condition is more likely to occur in environmentally corrosive areas. This recall will be launched in the "salt belt" states of connecticut, delaware, illinois, indiana, iowa, maryland, massachusetts, maine, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont... Hazard:this can cause increased stopping distances during low-speed brake applications, which could result in a crash.

While stopping from low speeds the ABS system activates on dry surfaces. This causes increased stopping distances.

2003 gmc yukon. Consumer writes in regards to intermittent anti-lock braking system. *smd the consumer stated while driving down the road, warning bells started to sound and the check brake system light, illuminated. The consumer checked the brake fluid, and found it was ok. The next day, he took the vehicle to the repair shop, where they replaced the pads and checked the system. They ran a diagnostic check, which verified the ABS had come on, but reset when the engine was re-stared. The brake shop recommended the consumer took the vehicle to the dealer. However, in their opinion the ABS module and ABS pump needed to be replaced. They explained to the consumer, when the warning light was on, the ABS was inoperative. The dealer informed the consumer, it would cost $125, just to run the diagnostic and if the module and pump needed to be replaced, it would cost $ 2,200. The ABS light stayed out for weeks. However, in march 2014, the light illuminated again.

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.

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.

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.

I have a 2003 gmc yukon and the electronic brake control module (ecbm) has failed. The ecbm is the feature that controls the anti-lock brake system (ABS) on cars and trucks. Without the ecbm working, a car/truck will not have ABS braking, which is a safety hazard for stopping and braking, especially since all new cars have this feature and most people do not know how to drive otherwise. I did some internet research and this appears to be a very common problem with gmc and all general motors trucks from 2000 to 2003 and other model years. There are thousands of people out there who have had this ebcm fail on them. I took my truck to the dealership and they informed me that there are no recalls for this part and further that the replacement part is $1,000, excluding labor. This exorbitant charge is cost prohibitive to most people and is dangerous because it is a critical safety feature. I feel like this part should be recalled at no cost to consumers. This is a critical safety issue and it seems like it is a common problem, which makes me believe it is a factory defect.
