The ABS motor/pump runs constantly when the engine runs and when it is not running. Even though I think I have antilock brakes when I need them; I do not! my ABS doesn't work. Chevrolet won't pay to have it fixed. Dealer wants $1,500 to fix.

While driving the ABS light illuminated intermittently and would remain lit while the vehicle was being driven. The dealership's mechanic informed the consumer of a possible ABS pump failure.

1999 Silverado Z71 pickup ABS control module failed. Chevrolet servicer joked that when they see one come in they don't even have to look at the vehicle to diagnose it because it is so common. He even stated that with the cost of the repair that it appears that Chevrolet discovered a way to increase new vehicle sales. Then he said maybe I should talk to a salesman while they make the repair. This is dangerous and certainly is no joking matter. Researched and it is very obvious that this is not just an occasional problem. Considering a vehicle costs $30K & the danger I think Chevrolet should do a recall.

1999, Chevrolet, Silverado, at 45000 miles the ABS light came on. The ABS motor continued to run even when the engine was turned off. It seemed like this was a safety issue and numerous incidents of this problem occurred. The module was replaced by the dealer. This problem made the ABS inoperative. The problem was diagnosed as an electrical failure.

My Chevrolet Silverado 4X4 ext cab while backing down boat ramp with 3000 lb boat during launch procedure on asphalt ramp in reverse gear activated antilock brakes and slid into water.

Brake failure. ABS activated on my 1999 Silverado pickup and truck would not stop and rolled into traffic lane from gas station. This has happened a number of times, necessitating pulling of the ABS fuse in engine compartment thus rendering ABS inoperative. Had wheel hub bearing unit replaced at a cost of $377 and the day after the ABS activated again and vehicle would not stop. Pulled fuse again and have not replaced. Checked around the country in NY and ok., and had sons check with dealers and they asked why do you want to know if a problem. Dealer here says not a problem but I feel it should be looked into before maybe more people have problem and are killed.

The ABS light illuminated, and when turning the vehicle off, the ABS pump continued to run. Also, there was a burning smell present while driving.

I work as a salesman at a small used car dealership. In the past few months, we have had at least 4 General Motors full size trucks (1999 Suburban, 1997 Chevy Silverado, 1998 Silverado, 1999 Silverado) have speed sensors fail, causing the ABS to come on at slow speeds when braking. At first, we thought that this was just an inconvenience, but I was recently test driving a 1999 Silverado, and when I pulled into my driveway, I was not able to stop and drove right into the garage. Fortunately, I was not stopping to let a pedestrian cross the street, because I would not have been able to stop and could have caused serious injury. This is a dangerous situation, and if I have experienced this problem on 4 vehicles, there must be many more on the road with this same problem.

The vehicle experienced a problem with the anti-lock brake motor. It continued to run even when the vehicle was off. The owner had to pull the fuse to get the anti-lock motor to disengage.

- Loveland, OH, USA

The consumer noticed the ABS pump would not shut off. This would cause the battery to run down. The vehicle was taken to the service station to have it checked. The mechanic could not determine the cause of the problem, and had not been able to resolve it. The ABS light had come on, the engine shut off and the fuse had to be removed to disable the ABS. The consumer requested that GM should cover the repairs due to the part being a safety feature.

ABS wheel speed sensors 1999 Chevrolet Silverado - ABS kicks in when slowing to low speed (no ABS or brake lights come on). Very dangerous! you have no control of the vehicle when this happens. I called several local Chevrolet dealerships about this problem and they are so familiar with the problem that they can tell you right away how long it will take to fix and how much it will cost (just by me telling them what the vehicle is doing). I was pulling into a parking lot, going less than 5 mph and the truck did not stop, I bounced off of the curb - due to the ABS kicking in when it did not need to. If I was slowing for traffic, I have no doubt that I would have hit the person in front of me! this is a very common problem (I have since researched this problem on the internet) and a serious one - this needs addressed by Chevrolet as soon as possible. My truck only has 57,000 miles on it - the cost of repair will cost up to $800 or more. The truck is unsafe to drive. Any response to this problem would be greatly appreciated. Thank you.

1. ABS motor started running while driving, then kept running, even when vehicle was shut off. 2. engine turns over but is hard to start if it sits longer than 15 minutes and less than 6 hours 3. while idling, engine occasionally shakes and sounds like it's going to die.

While driving the brakes operated poorly, intermittently took them a long time to slow the vehicle down. Vehicle was taken to the dealer on two occasions, and consumer was told that the braking system was working normally.

My father-in-law pulled up at work. He turned the truck off and he heard a noise under the truck near the drivers door. He looked under the truck to see what was making the noise and found the ABS pump still running. He had the mechanic at the job site look at it and he disconnected the pump. The ABS light as well as the brake light came on but the truck was drivable. He told me about it and I did some research and found that it is a very large problem! Chevrolet is refusing to recall the part and putting the general public in danger. If the ABS fails during bad road conditions everyone is at risk. The occupants and the other drivers on the road. This needs to be put into a force recall by the NHTSA for the safety of the general public. There should not have to be deaths on the road before safety issues are addressed. Please act swiftly in this matter before the deaths start showing up from this issue.

Brakes pulsate when coming to a stop or over rough/bumpy roads. This has been happening since I owned the truck. Dealer informed it was normal. In the past two weeks I have been having a problem with the ABS light occasionally staying on and during the first braking where the truck will not stop and the brakes chatter or pulsates but then will work fine for the rest of the day. Brake fluid is fine.
