The ABS light came on and the ABS pump runs continuously even after the ignition is turned off. The only way to shut off the pump is to disconnect the battery or the pumps power supply. Chevy says so far that they are unaware of the problem, but they are looking into it.
1999 Chevrolet Silverado brakes complaints
Page 25 of 35: complaints 701 to 730 of 1,003, newest first, as owners wrote them.
Gas pedal sticks every time you start the truck, which makes you lunge forward or backwards every time you drive. I have read numerous complaints on this situation & I think it should be recalled. The ABS system went out and when I took it to the shop they said it was very common for the chevrolet, silverado to do that, I think it should be checked on too.
Electronic braking control module, which is part of the ABS brake system, malfunctioned, resulting in lack of ABS brakes. Also caused battery to drain within 12 hours with vehicle turned off.*ak consumer disconnected fuse for ABS brakes to prevent battery drain, the motor continues to run after the vehicle is turned off.
Abs brake boxes failing. Causes box to run with the ignition switch turned off. Fuse must be removed to cut power to box. When power is cut ABS system no longer is in service. Boxes are not replaced at manufactures expense if vehicle is out of warranty. Cost is extremely high for consumer, $1000.00 to $1400.00. This problem is occurring with chevrolet and gmc trucks equipped with ABS brakes. This situation creates a fire hazard, a braking hazard and economic hardship on the consumer.
Abs light came on at 40 MPH. When shutting off engine ABS pump kept running. Dealer determined ABS pump needed to be replaced.*ak consumer feels chevrolet should pay for the service of their failed component. Also the steering clunks when going over bumps.
Consumer stated the ABS light comes on and engine starts making a noise. When vehicle is shut offthe ABS motor continues to run. Nlm
The ABS motor won't shut off. I had to remove the fuse.
Abs module has failed I have been told by some techs that work in dealerships that this has occured in other makes and models like mine. They are telling me it will cost me 900.00 to fix it ,meantime I have no ABS brakes.
Consumer states when the vehicle is in 4-wheel drive, and he accelerates quickly, and then lets up on the brakes, the ABS goes into effect without consumer touching the brake pedal, this only happens when there is snow/ice on the roads, consumer has no control of the braking, consumer contacted the manufacturer and was informed that they were aware of the problem and had no plans of correcting it.
Upon placing vehicle in park ABS brake system was running after vehicle was turned off. Took vehicle to dealer, and mechanic advised consumer to unplug ABS system or have it replaced.
Purchased car, 10/06/2000. Upon braking over bumpy road, brakes seemed to slip, and made a thumping sound. Dealer said front brake rotors were out of round. The rotors had just been replaced, and they refaced both front brake rotors. On, 11/01/2001, after a car wash, the ABS motor ran non-stop after the car was turned off. Dealer "tested" ABS system, advised pump motor had "failed" and replaced it, at a cost of $979.04. On march 20,2001, the ABS light came on when I was leaving work. Dealer advised that the part they had replaced in nov,2001, had "failed" and they would replace free of charge. They called to say when they did replace it, it shorted out, and now we needed a "modulator" at a cost of $600.00 plus labor. I believe that this is a serios safety issue with these trucks and I know that many of them have had the entire ABS systems replaced. If chevy knows the location of the ABS is a problem, why hasn't it been corrected? And repairs relating to a design flaw should definitely not be the consumers burden.
Consumer states the ABS motor remained on after turning off the vehicle, dealer notified. Nlm
At 60 MPH there was vibration and shaking in vehicle when braking, dealer determined the ABS pump needs to be replaced. Nlm
Parking brake will not hold vehicle on modest incline.
A recall was issued for this problem on 2000 models, however, my truck is a 1999. I doubt this was a coincidence since I had the exact same failure. This part is virtually impossible to abuse under any driving condition. I feel this part is inherently defective and gm should shoulder the $1,000 repair bill.
Abs light illuminated while driving; upon parking vehicle with ignition off, ABS motor continuously running, requiring fuse to be pulled to deactivate pump; service technician identified bad control module and ABS pump/motor; current technical service bulletin #220101; chevy first agreed to reimburse 25% of repair (parts only) but would not honor after they learned of independent garage repair.
While traveling on highway ABS braking light and parking brake warning light appeared on dashboard. Applied brakes, pedal vibrated and went all the way down to the floor. Dealership was aware of problem.
Consumer has to go under vehicle to disengage engine from running upon turning vehicle off. Please provide any further information.*ak the ABS brake system collapsed while driving. Heavy drain on engine and battery. The regular brakes remained functional.

While driving at highway speed anti lock brake light illuminated. Driver shut off truck and removed key. Driver could hear a loud buzzing noise that would not stop. Driver located box were noise was coming,m and could feel heat, and it was getting hotter. Consumer had to unhook battery cable. Consumer felt vehicle could have caught on fire. Chevrolet has been contacted.
Abs unit went out last month; continued to run after motor was shut off; after checking around, unable to locate part because all on used vehicles are already gone on this year model. Have also found out that several other people that I know have had the same problem with the same year model ABS unit. Only unit that can be found is a new unit through gm at the dealer not at an auto parts store at all. They cannot keep them in stock. Suggest that there is a defect in this unit. Have mine still disconnected till I can find one that is not $700.00+ dollars, but have checked the web around the us and am still unable to locate any for a 1999 chev. Pu. Suggest there is a problem.
The truck was started and the ABS motor started a whirring sound and would not shut off. The manufacturer, chevrolet, informed me that because I'm out of the warranty period there's nothing they can do and that there is no history of this defect.
Abs braking light appear on dashboard permanently. There is a loss of braking power. Dealership is aware of problem.
Front pads have never required replacement as of 102000 miles. There appears to be a very serious design flaw with the rear caliper braking system. Cause possible loss of braking and serious accident or fatalities.
I have complained of a very soft brake pedal ,will go almost to the floor, the problem still exists, I feel very unsafe driving this vehicle. The dealer said this is a normal feel.
Abs motor continues to run after engine is turned off. Abs motor is located in terrible position under driver side door. Bolts to system have rusted due to placement of motor. Abs light stays on and motor runs continuously. Dealer says problem is electronic brake control module. Very expensive to replace and will problably just happen again in another 45,000 miles. Some dealers say just to disconnnect fuse to ABS motor, which could lead to a major problem. Chevrolet should make this a recall.
Abs pump is continously running. Also, ABS light stays on, but the system will not work. Contacted dealer.*ak
