2000 GMC Yukon brakes complaints
Page 3 of 3: complaints 41 to 59 of 59, newest first, as owners wrote them.
Owner applied the brakes and brake pedal went to the floor. Vehicle was not stopping upon brake application. This caused vehicle to continue forward into intersection. Driver made an emergency right turn which then resulted in the vehicle sliding and then flipping over. Please describe details.
When brakes were applied to stop vehicle they didn't hold, brake pedal went to the floor. Causing an accident.contacted dealer.
While driving and when using the brakes, they will work intermittently, the brake pedal will go to the floor, causing vehicle to have an extended stopping distance. Dealer will be notified.*ak the failure started about 6 months ago. The brake when depressing would go about one inch from the floor causing a panic situation. This failure occurred several more times.
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. *jb ***dimsii ivoq entry posted after 12/12/02 cut-over to artemis****761455
Emergency park brake failure.
Consumer applied emergency brake and pedal went to the ground, resulting in emergency brake malfunctioning.
When applying brakes vehicle has a winding noise. Also, when braking vehicle will jerk. And dealership is aware of problem.
While braking lightly at 30 MPH vehicle brakes locked up, causing vehicle to fish-tail and become uncontrollable. Brakes did not return to normal, they continued to lock the wheels and the vehicle crashed into a pole flipped over, and roll approcimately 3 times.
When applying pressure to brake pedal it will go directly to the floor during hard braking which could cause a crash due to failure of the brake system to engage. Also, during light braking, brakes engage at first. Then , brake pedal will go to floor. Dealership has informed consumer that this activity was considered to be normal operation of this model of vehicle, and there was no need for correction. Please provide any additional information/attachments.
The parking brake system is not designed to hold more than the weight of the vehicle on more than an eleven percent grade. The yukon xl is advertised by gmc to be a vehicle capbable of towing a 7800 lb trailer. With a boat trailer or horse trailer you can not safely park on anything but level ground without the weight of the vehicle and trailer being held by the tranmission park. This not a safely designed system.
Rear windows inoperable 3 times/right front seat belt locks up, have to unbelt to get slack so passengers reluctant to use belt/transmission has trouble finding first gear/rear end hums/front end feels "loose" after control arms replaced twice/tires squeal at very low speeds/accel pedal stuck to floor, then started coming apart/air bag warning light came on until 3rd repair/leather seats split at seam, repairs sloppy.
Transmission problem: at 40 MPH going downhill unknowingly went into neutral and accelerating to maintain speed went over 3000 RPM. Normally at that speed 1400 RPM. Transmission bolt missing. Found by owner after dealer performed oil change. No paint scratched where bolt would have been if there was a bold there from manufacturer. Dealer replaced bolt at no charge. Hot front brake left side & tire feels hot - noticed by smell from left side - right side front no heat or smell. Found after traveling 60 MPH and wheel & tire hot to touch. Dealer examined all brakes, claimed all normal, even brake pad wear on all brakes and found no abnormal conditions, but no problem since they dealer looked at this.*ak (tiresize: 265/16)( dot number: tire size: 265/16 )
While traveling on highway traffic began to slow down. Consumer stated that a hard spot came into the brake, and brakes were locked, consumer could not stop, and rear ended another vehicle which caused a chain reaction.
While driving would step on brake pedal and vehicle would not stop on time, causing it to pass through intersections. This has happened seven times. Dealer could not fix the problem.
Slowing to a stop on slight downhill grade, the brakes failed for appx 3-4 seconds. The brake pedal raised up towards me and couldn't stop the vehicle. This has happened at least 20 times(always on dry roads).it also occurs at slowing down speeds, if road is ever so slightly rough. * not overly bumpy !!
When applying brakes rear brake will lock up before the front brake, causing extended stopping distance. *ak lock up of rear brake could cause loss of control on wet or icy pavement. Tires leave black marks on pavement. Brake proportioning system not working correctly.
While driving down a hill today ( I was using the gears so the brakes were not overheated)...the brakes completely failed mometarily when I reached the bottom of the hill - I almost hit the car in front of me. When I tried the brakes again immediately thereafter (after going through the intersection) and they were perfectly fine.
When you go to apply the brakes, with a constant pressure on the brake pedal, you receive no tactile feedback via increased resistance in the brake petal that the brakes are being engaged. You can press the brake petal all the way down and still not get a positive feeling that the brakes are being applied. The dealer refuses to do quantatative measurements on the brake system to see if it is within manufacturer specs. The manufacturer wants to wait over 7 days before another dealer can see the vehicle and conduct tests.
