The design of my 2000 GMC Yukon's emergency brake is faulty. The emergency brake failed on my car twice. In April of 2002, my car failed inspection due to the emergency brake not working. I had to pay $550 to replace the brake pads and replace a rear rotor that the emergency brake had damaged because the emergency brake pads had worn down and the base of the brake damaged the rotor. The car passed inspection but the brake did not seem to work well. So in 2004, inspection time rolls around and my emergency brake again fails. I was told GM had placed a recall to fix their faulty design but I am not sure if that is true or not. Either way, the design on this car is terrible. The only time the emergency brake is ever used is when the state inspection service tests it to see if it works. GMC should fix the brake system where the emergency brake should not be a $400 problem every two years.

Parking brake issue. I occasionally noticed a scraping noise coming somewhere from the rear of the car. The servicing dealer pulled the rear break rotor off to inspect the parking brake. They found that the pad had worn all the way down to the metal and that the noise I was hearing was the remenants of the shoe, the liner, scraping against the drum. The dealer maintained that I must be driving with the parking brake engaged. I maintained that was not true, that there must be a design flaw with some of the brake components causing the unintended engaging of the parking brake shoe and the drum. I contacted GMC directly a spoke with a service representative who maintained there was nothing he could do to remedy the problem. I did not want to simply replace all the parking brake and drum as I felt there was a design problem and that my issue would be recurring. My main concern is that the brake shoe liner could eventually wear out the drum and possible cause a crash. However, I am not able to stop driving the car. Subsequently, after researching the NHTSA site, I found GMC's service bulletin, NHTSA # 10000172 describing the problem and the recommended fix, which was replacing a part with a "newly designed part ( a tension spring)! the service bulletin did not state that the problem was caused by drivers driving their cars with their parking brake engaged. I believe that enough owners complained and GMC realized that it was a design problem. The bullentin covers serval GM models. Again, the problem is not the noise caused by the scraping, but the potential accident caused by the brake shoe liner eventually wearing thru the parking brake drum possible causing the rotor to seperate. This could happen while driving at highway speeds. A loss of control or sudden stop probably would take place. I think that could be very serious and needs immediate attention.

My parking/emergency brake goes all the way to the floor and does not hold my vehicle on even the slightest grade. The dealer states that this is normal per GMC even though they have had numerous complaints. My engine has a knocking noise when I start it up in the morning. The dealer also stated that this is normal per GMC. My front passenger bucket seat back moves forward and back (wobbles). My rear end wheel bearing were replaced because of a loud hum. That was misdiagnosed twice by alfred mathews. My front end feels loose and squeaks when accelerating or braking. Rear leather bucket seats rattle all the time when driving and the leather has ripped @ seams twice. Alfred mathews replaced once and tried unsuccessfully to fix seat rattle. My newest complaint is a noise that comes from the rear of the vehicle when you shut the doors. ***dimsii IVOQ entry posted after 12/12/02 cut-over to artemis****761455

The parking brake on my 2000 Yukon would not hold the vehicle when the parking brake was applied and the transmission was in neutral. This condition existed when I bought the vehicle new. When I took it back to have the problem fixed, I was told this vehicle has a new type parking brake. It was not designed to hold the vehicle with the transmission in neutral. It would only hold the vehicle with the transmission in park. After two years of the parking brake not holding I had it in for service and inquired one more time about the parking brake. The dealer checked it and told me the brake pads were worn out and need to be replaced. The dealer replaced the pads and made some other changes. Now the parking brake does hold the vehicle with the transmission in neutral. I feel I have been deceived and taken advantage of since the dealer told me there was no problem until the warranty had expired. I would like to know if there has been other complaints of this type.

Vehicle parking brake was inoperative. Consumer pushed lever to engage parking brakes, but vehicle was still mobile. Ts parking brake will not hold on the slightest grade especially with consumer's boat attached. Failure of the parking brake could result in the vehicle and boat to submerge in the water.
