My GMC Yukon experienced total brake failure. My wife was driving with our 3 month old son and luckily she was able to stop off of the side of the road in a field. When I arrived, I found a puddle of fluid under the driver side seat from badly corroded steel brake lines. After only a few minutes of online researching, I have found thousands of similar stories; some of which ended much worse. Clearly this is a quality and safety issue.

The contact owns a 2000 GMC Yukon. The contact stated that the ABS system activated independently while driving 5 mph, causing an increase in stopping distance and time. The contact had the vehicle serviced under NHTSA campaign I.D. number: 05V379000 (service brakes, hydraulic:antilock) but the repair did not remedy the issue. The contact had the wheel speed sensor twice but it also did not correct the issue. The failure mileage was 82,000.

After no warning (lights, chimes or alarms), applied brakes and pedal went to the floor. No brakes. Luckily it was very early and nobody was on the road when I blew through a stop sign intersection. Local dealer says aluminum brake lines were severely corroded and had ruptured. Nearly $2000 to replace aluminum brake lines with steel. Everyone knows when you place different metals in contact where they can get wet, you will get electro-chemical corrosion of the weaker metal, in this case, aluminum. That's why boats use aluminum and zinc as a sacrificial metal in marine environments - to protect the engine from corrosion. This is surely an engineering flaw. On my Yukon, the aluminum brake lines are attached to the steel frame underneath the vehicle where they are sure to get wet anytime it rains, thus guaranteeing the weaker aluminum metal will corrode. I have a 45-year-old mustang with original brake lines (steel) and no corrosion. 10 years is absolutely unacceptable for brake lines to be corroded to the point of catastrophic brake failure through normal use and normal weather. I live in Maryland, not Alaska. Our weather is average. There should be a recall and I should be reimbursed.

June 2010 as I was pulling my 2000 GMC Yukon into a parking space the anti-lock brakes locked up and I crashed into the vehicle facing me. Limited damage was done to the other vehicle. There was nothing I could do to stop my vehicle from hitting the other car. There had been no signs of anything being wrong with my brakes before the incident. Since then my vehicle has continued to lock up at random. I called the local dealership and they said there was no recall. After searching the internet, I found that there was a recall in 2005 in some other states with the exact same problem. Of course the state I live in was not included in the recall and once a recall has been issued, it will not be issued again in other states. Therefore, I am faced with the expenses of fixing a problem the gmac knows exist at my expense!!!!! I'm sure it will not be cheap. Thank you gmac!!!

The contact owns a 2000 GMC Yukon. When the contact depresses the brake pedal at low speeds, he can feel the ABS pulsating. As a result, the vehicle is more difficult to stop. Also, the contact hears a humming sound whenever the failure occurs. The contact did not notice any differences beforehand and the vehicle has not been diagnosed by the dealer. The current mileage was 174,000 and failure mileage was 172,000.

Ref present recall on 1999-2002 Chevy & GMC Silverado, Yukon light trucks. I notice that rust is the factor in the anti-lock sensor recall. I would like to further add that rust is also responsible for breakdown in entire braking system. I have a 2000 Yukon with 26000 miles that has extreme rust decay to rear axle backing plates and front rotors. The local dealer when questioned admitted its due to rust belt issues. I did notice that GM has admitted to having rust belt issues with its braking system. Why are you not requiring them to mitigate the entire system which is effected" are they not part & parcel of the braking system" why should the consumer be saddled with the expensive repair of replacing theses components which if they have not failed seriously impair the braking and handling of the vehicles in question. My mechanic advises that he has had many of the same vehicles come in for repairs with identical rust disintegration. The area of vehicle sale & use in this country should not be used as an excuse by the manufacturer.

My concern is the parking/emergency brake. I have taken the vehicle in at least 4 times since it was new with complaints the emergency brake doesn't work. "adjustments" helped only temporarily. I am now informed the emergency brakes are worn out and need to be replaced, of course at my expense. I was also told I was responsible for the problem, as I had to be driving with the emergency brake on. This is not true. I looked at the center for auto safety for this problem and found other owners of GMC Yukon have had the same problem. Very few owners check the emergency brake routinely, in my opinion, and it is likely the problem may be a common one, and thus a safety issue. Basically for the 3 years I've owned my vehicle, I have had inadequate or non-functioning emergency brakes, which I feel has jeopardized my safety. My vehicle has 46000 miles, I have had the brakes repaired by a non-GM facility, with good results. I was also told there was evidence the brakes were seriously out of adjustment, and had wear patterns which would indicate a cause other than my driving with the brake on. I plan to meet with the service manager for my dealer and discuss this matter further. My expense for repair was approx $250, done about 2 weeks ago after the dealer had inspected the brakes and declined to repair. I felt I had been given misleading information as to the cause of the problem. Early in the history of this problem, I was told the brakes were working as they were supposed to. Naively I accepted this explanation, until my last visit with the dealer. I suggest a survey of 1000 owners be done, with self check of emergency brake function, to determine if this problem is a common one. Thank you. Please let me know if I can be of any further assistance. Jerry R. crews, M.D.
