Electronic brake control module failed and continued to run causing my battery to run down. After much research, it is apparent that this is a common occurance for 1999 -2003 gmc sierra's and chevrolet silverados. Gm dealerships want nearly $800 to make this repair for a part that was defective in design and in quality. The ntsb and/or the federal safety agency should mandate that gm recall and correct the deficiencies in their product instead of simply issuing a service bulletin just one month prior to my warranty running out.
1999 GMC Sierra brakes complaints
Page 7 of 12: complaints 161 to 190 of 338, newest first, as owners wrote them.
On four separate occasions my 1999 gmc sierra had problems braking cause close collisions. When pressing on brake at low speeds to come to a stop brake pedal was hard to press down. Seemed like brake booster went out. Had to apply extream amount of pressure on the brake to avoid collision. Had vehicle checked out by certified mechanic which found nothing after hooking up diagnostics test and also manually checking out brakes. Found nothing on computer to say why brakes failed. If anyone knows why this is please email me at [email protected] luckly there has been no collisions.
While traveling consumer noticed ABS indicator illuminated, resulting in ABS motor running while vehicle was turn off. Dealer has been contacted.
After driving vehicle consumer kept hearing a humming sound coming from the front end. Upon closer inspection, consumer found that ABS control module was still running, even with the engine off. Consumer had to disconnect the module to keep from draining the battery.
While driving brake pedal has to be depressed down to the floor to get the vehicle to stop. Dealer has replaced the anti lock brake control module and the master cylinder, but the problem still exists.
While vehicle is running ABS light is always on. When vehicle is parked there is a loud humming sound coming from the brake pressure modulator. Vehicle was taken to the dealer who informed the consumer that the brake pressure modulator failed. *ak
Consumer stated while having vehicle serviced, technician noticed both rear rotors were rusted.
Both rear rotors are badly rusted. Dealer will repair at consumer's expense of $714.00. Vehicle had only 19,000 miles .
Abs went out. Dealer said that it would cost $795 for module and $130 for instulation. Only have 35,000 miles on truck. (gmc sierra).
Abs and brake light are on. Had problem diagnosed by dealer and was told truck needed a new ebcm (electronic brake control module). Part alone is $800.00 plus tax and labor. Got on a gmc truck owners website and found many other owners with the same problem.
Abs light is on, took the truck to the garage, said it needed a new ecbm, 700.00very car and truck on the road has a problem, now, why shouldn`t the manufactures, be responsible for there mistakes, we pay enough for there mistakes.
Abs module failed, causing pump to run continuously. Necessitated removing fuse on ABS system which causes brake light & ABS light to burn all the time. Dealer said my problem, not gm's. Truck has been dealer serviced at all required times. I would think a brake system failure, even if a redundent system, would pose a safety issue & repaired by gm. The ABS system was standard equipment, not optional to the buyer.
The consumer stated anytime the vehicle came to a stop at an intersection, stop sign, light or uneven pavement, the anti-lock brakes engaged, which caused the brakes to momentarily fail. *ak
Anti lock brake control module shorted out requiring stopping on busy road and removing a high amperage fuse from road side of vehicle, and loss of anti lock brake capacity. Vehicle has only 34000 miles.
Consumer states that when trying to apply the anti lock brakes, they will lock up causing the vehicle to have extended stopping distance. Dealer notified.
Consumer states that brake rotors are wearing. When applying the brakes the vehicle will have a heavy vibration and extended stopping distance. Dealer notified.
Abs control module failed on 1999 gmc sierra 1500 4x4. Gmc dealership diagnosed failed wiring in ABS pump resulting. I think the ABS system should be absolutely reliable as this is an important safety feature.
Consumer states that stopping distance has increased, and that braking capability intermittently does not function. Dealer diagnosed that the anti-lock brake module had failed.
Brakes do not always stop truck, very unreliable.
When the engine was turned off, the ABS module contined to run. Ak *cb
Consumer stated that while driving and without warning ABS failed. Dealer notified.
I started my truck up and heard a vibrating noise and the ABS light came on. When I shut off my truck the noise continued. I unhooked the battery cable until I determined the problem was the electo-hydraulic control unit. I pulled the fuse and checked with my dealer. The service manager advised me that both parts of the unit (bpmv and ebcm) usually need to be replaced at a cost of approx. 1600.00 for parts alone. This truck has only 42,000 miles on it. I also changed the brake fluid at 30,000 miles in order to avoid this problem. I consider the replacement cost for these parts to be outrageous. The fuse can be left out and the vehicle can be driven without the anti-lock feature working. I consider this a safety defect because very few people will pay this price to have the anti-locking feature restored. In addition, the ABS and brake warning light come on and cannot be cleared when driven with the fuse pulled. This can cause a driver to miss other problems that would be indicated by the brake warning light.
Abs pump runs even with key off! Only way to stop it is to pull fuse. Abs and brake warning lights stay on all the time. Did not initially notice the problem until I made a tire screeching panic stop. Dealership stated no recall.
Abs ebcm failed and continues to run with ignition off.
1999 gmc sierra ABS motor stays on continuously. Had to pull the fuse to stop it. The ebcm had to be replaced. The repair cost $1,105.00. The technician said he had seen it before and I see that many people have complained of the same issue on this site. The failure occurred at 46,775 miles which is also consistent with other data presented. Gmc needs to do a recall and compensate us for the expensive repairs.
I experienced a humming sound coming from my vehicle when the engine was not running. I went to a gm dealer to see what the problem was. The service tech said immediately that it was bad wiring in the ABS motor causing it to run at all times. This was a repair that needed to be completed immediately because the motor was running off of my battery. The dealer said that he has seen a few of these vehicles with the same problem. I proceeded with the repair and spent about 900.00. This is not a recall, at least I am not aware of it, and should be investigated.
Abs module failure. My truck had problems with the ABS activating since it was new. Just recently I have joined the ranks of owners with continuously running modules. When I found out it would cost at least a grand to fix, I pulled the fuse.
Abs control module failed. After turning off vehicle, ABS module continued to run. Had to disconnect ABS module to stop it.
The anti-lock brake system failed, which caused the vehicle to experience extended stopping distance.
While driving the ABS light come on and and stayed on. I heard a loud noise coming from underneath the driver side door. The noise continued after the vehicle was turned off and it wont stop. I pull out the ABS fuse and the noise stoped. I took the truck to the dealer and he said what it was. The ABS control module was shorted and the motor wont stop. It cost me $900.00 dollars to repair this problem after I talked out the service person, I think this is way to expensive and to soon to failed, for what I have found out gmc needs to issue a recall on this system. Respectfully submited. Juan pinedo.
