This morning as the vehicle was "turned on" and proceeded down our residence driveway, the ABS light came on as well as a whirring sound emanating from the rear of the vehicle; stopped vehicle and turned it off/then on again; the whirring continued while engine was off and ABS light came back on when vehicle was turned back on; drove to dealer who said the ABS module needed to be replaced at a cost of approx. $1,000. They could not determine the cause of this problem; I called manufacturer who said it wasn't covered as the warranty expired at 36,000 miles;

Gmc has finally acknowledged there is an issue in their ABS dump valve module for the first year 1999 new style pickups. I have had my truck in 5 times with 25 seperate total losses of brakes when you apply them. The fluid bleeds down allowing the brake pedal to go to the floor with a groaning noise.they just replaced this component for the first time. It was expensive so they waited this long to fix it. This is a saftey issue for sure. There should be a recall.
The rear emergency brakes were replaced at 47000 miles and again at 66000, the consumer found out that a retained pin had broken each time causing the emergency brake shoe on one side of the truck to engage and wear completely off. Nlm
No summary listed for above vehicle.
Abs brake motor keeps running and system keep working as though foot was on brakes and vehicle sliding. Also, had to take fuse out to stop ABS motor from running. Contacted dealer, and dealer stated what it will cost to fix.
On 10/23/01 I started my truck and reversed in my driveway, and my brakes locked up. I put the truck into park and shut off the ignition. At that point I heard a humming from under the transmission. I disconnected the battery at that point and contacted s&k poniac in springfield, il, the local gmc dealer. I explained what had happened and the service manager knew exactly what it was, without even seeing the truck. I was advised my ABS had failed and that repair would not be covered under warrenty. On 10/24/01 I contacted several service centers concerning repairing this problem and learned that this is becoming a common failure in this model/make of truck (chevy's also) at the approximate same mileage as I am at. The repair is extremely costly and because of the way the ABS is intregrated into the vehicle it cannot be disconnected. I have discounted auto insurance because the ABS is on this vehicle, standard practice in the insurance industry. I searched for a recall, or any information,. On gm's website but was unable to find anything related to the ABS failure. I am concerned that this very imporant safety feature is failing in many of this make/model/year truck and that a recall should be done. The manufacturer must be held accountable for safety related features. I own a nissan and all safety features are covered for the life of the vehicle.
Abs module failed, causing a humming noise from beneath the vehicle, the noise did not stop when the engine was stopped and the key was removed.
Anti-lock brake failure.
After starting vehicle in cold weather brake light came on, and brakes locked up. Vehicle would not move. Once vehicle got warm it still would not move. Please provide any further nformation.
Trouble with rotors-8000 miles & rear brakes started to hang up & lock up. 8400 miles rotors were replaced - 29100 miles all four rotors had to be replaced again. Original factory brakes had 50% lining left - rotors were badly scored and chewed up - rotors over heated and delaminate-they are of very poor quality.
Abs module kept running after the vehicle was turned off, had to un-plug the ABS motor now the ABS and the brake lite stays on all the time. Need's to be a recall on this part after all the problems people are having with the important parts of a new trucks braking system. How many more will have to go out/fail before there is a recall on it, not many I hope. Let down on the dependability of this new truck, my 1995 chevrolet was more dependable than this one. And it had 350,000 miles on it before it finall layed down!!!!
While traveling approximately 10 MPH brakes failed, causing truck to impact side of a mountain. Recalls 00v345000 and 00x001000 repairs has already been performed. Dealership has examined vehicle multiple times for brake related issues, but no determination has been made as to failure of brake system. Please provide any additional information / attachments.
The rear emergency brakes failed twice prematurely due to broken a retaining pin which caused the emergency brake shoe to engage and wear completely off, also the rear brake pads were replaceed.
While driving 5 MPH and applying brakes ABS braking system malfunctioned, causing extended stopping distance. *ak ABS system completely went out, resulting in two warning lights illuminating, ABS system (motor) could not be shut down until battery cables were removed.
I have had ongoing problems with the brakes on this truck since I purchased it brand new. When I attempt to stop and rollover a small bump or hole in the road the brake pedal losses pressure and the pedal goes all the way to the floor. In california where I live, it is very hilly and I drive on hills on a daily basis, however I have had to adjust my normal driving and begin to brake 100-150 feet before coming to stop sign to protect my family. When the truck rolls over a small bump or hole, the vehicle will not stop and go right through the intersection. I have taken the vehicle to three (3) different local gmc dealers and they all said that this was normal ABS brake operation. I told each of them that this was not normal braking operation. On june 11, 2001, my family and I went to the local supermarket. When I stopped the vehicle I heard what sounded like an electrical motor running underneath the truck. I drove the vehicle home and called for a next day appointment at the local gmc dealer. The next morning when I attempted to drive the vehicle to the dealer the truck would not start, the battery was dead. I called aaa and they came and jumped the dead battery and drove to the dealer repair shop. The dealer stated that the ABS control had completely failed and replaced it. However, I still have the same braking problems I had prior to the dealer replacing the 4-wheel anti-lock brake control.
Dealer diagnosis is engine knock hot or cold see history piston moving in cylinder making noise operating to manufactures specs at this time---performed decarb 2 times per gm recommendations noise returns currantly no resolutins per gm for noise. That means that I pay thousands of dollars for a deffective turck, the factory warranty it going to expire when the truck hits the 36000 miles dealer explain to me that when gm find how to fix the problem I can go back and gm going to fix the engine of my truck, I'm sceptical for this comment. Gm built thousands of this kind of engines and I dont think that gm going to expend money and time to fix engines when the wararnty al ready expire.
Abs brake light illuminated and remained on indicating a malfunction within the system , cause unknown. Please give any further details.
Vehicle went through inspection in may of 2001. Techician stated that rotors were pitted, showing spots where big pieces were broken off. Before inspection brakes made a squeaky and grinding noise. As problem increased brakes began to chatter. Rear brake rotors were replaced and the front rotors still remained on vehicle.
After getting home and turning off engine could still hear motor running. Then, took vehicle to dealer. They said that defect was with ABS module which they could not fix.*ak
When applying brakes to make a slow stop vehicle will not stop wihtin last 10 feet of driving ,and at the same time there is clicking, ratching noise undereneath hood on driver's side that lasted 10 feet. Vehicle actually travels 15 feet before vehicle will stop.
Placement of the ABS control module (in the frame rail under the cab) subjects it to corrosion from road salt and other debris. Gm knows about the problem and should fix it as it is a safety issue.
Brake pedal depressed to floor with no braking action. Dealer did not write up problem shortly after initial incident. After multiple incidents, vehicle taken to dealer and owner demanded investigation (may 25, 2001). Dealer could not detect defect.
Vehicle vibrates when brakes are applied at any speed. Consumer's mechanic found that front and rear brakes were rusted. Dealer stated brakes were normal.
