Air Brake Antilock Control Unit/module Problems of Chevrolet Silverado - part 1

On my way home from a boy scout meeting, I heard what sounded like an electric motor or pump running continuously and the check abs light was on on my dash board of my 1999 Chevrolet Silverado 2500 hd extended cab 4x4. The next morning I took it to a brake shop and they tested it on the computer and confirmed that the abs system had failed. If general motors put out a recall for this part, I was never notified and never received any recall notice. I have since found out that the abs systems failure is a common occurrence. So, why no recall?.

Abs motor continued to run and would not shut off. Had to disconnect the 60 amp fuse to prevent battery from running down. Am told that the abs module is defective and will cost well over $1000 of my money to repair - this has not been recalled. This from a chevy with 80,000 miles?? I've discovered that this is not an isolated incident, that this is a common defect with this vehicle. I was told by the dealership that this failure occurs so often that they keep 4 to 5 units in stock. Why isn't this being recalled? what else can we do?.

2001 chevy Silverado z-71 - 78,000 miles - abs brakes engage during normal road conditions at slow speeds (under 10mph). This occurs 80% of the time the vehicle needs to brake. Mechanic has quoted me $900 to replace abs control module. Needless to say, this a very dangerous problem!!! gm needs to resolve this problem before someone is seriously injured or killed!!!!.

My father father-in-law is a certified mechanic and was doing some work on my 1999 Silverado and noticed that the abs motor was continually running. To stop this he had to pull the fuse. I recently drove my truck from minnesota to California and on numberous ocassions I had trouble stopping. I had to push the brakes all the way to the floor and the truck still was slow to react. Most of the time there was no one in front of me, but there were a couple times when I almost rear ended someone. I haven't done anything to correct the problem because I live in overseas. The truck is left in minnesota and I drive it whenever I am home for vacation. Once I move home next year I will have to do something to fix this problem if chevy hasn't sent out a recall. How many stories like this does it take for Chevrolet to do something about it? how many complaints have to be submitted about an abs motor that won't stop running unless the fuse is pulled? I sure hope chevy does something soon.

Driving with family abs light came on. When shutting down the engine, a pump noise continued. The pump continued to run and drained our battery leaving my family stranded. Tow truck mechanic, disconnected the pump, jump started our battery, and we brought the truck to the chevy dealer. Dealer said it was the abs module and would cost $1100 to repair! researched the internet and found there were many complaints about this problem.

2000 chevy Silverado, anti-lock brakes (abs) computer malfuntion. Abs comes on during normal driving and braking! had to pull fuse to keep abs from malfuntioning. Unable to stop at sotp signs at all with abs connected.

Abs module failed on my 1999 Chevrolet Silverado 1500 ext. Cab truck. The module stuck and kept abs running till I unpluged fuse. Luckly there was no accdent. But I checked with my dealer" no recall " said they had replaced lots of these module. So I had to have them replace at a cost of $923. 00. Guest that is why Chevrolet has not recalled!!!!.

Total failure of the abs braking unit.

On Monday, March 21st, 2005, when my 1999 chevy Silverado truck was started, the abs light came on and a loud buzzing sound from under the truck started. When the truck was turned off, the buzzing continued. The 60 a fuse was removed to finally making stop, after running the battery down the first day. This is a major safety issue that shoudl be recalled or on extended warranty. I read on a website that many many other truck owners have had the same problem. I am looking at upwards of $1200 to have this module on the abs pump fixed, and that might not solve the problem long term. It could happen again right away. I would appreciate gm or chevy recalling this malfucntion to the abs before a serious accident takes place. I purchashed a chevy truck to avoid these types of issues. Now I have a $1200 estimate to fix a problem that shoudl be under warranty or recalled. Please inform me as to how much chevy is willing to reimburse me on this major problem that is chevy/gm's fault. Michael a. Setlak 8937 nautical way new haven, in 46774.

Abs pump on my truck will not turn off and without abs the brake system could lock and injure many people. They should recall this before someone gets hurt.

The brakes are weak & when going downhill on a bumpy surface,they go to the floor& you don't know if it's going to stop.

While driving my 1999 chevy Silverado, the abs light came on and stayed on. A little searching brought me to the abs module on the frame under the left side of the passenger compartment. It was running, even after the vehicle was turned off and the key removed, it continued to run. I disconnected the power to the unit and tapped the wire up so as not to let it get wet,(obviously,it's carrying a lot of juce. ) when I took the truck to the dealer where I had purchased it the service manager told me that the entire module was bad and it would cost nearly 1000 dollars to fix. He said that the module itself was going to cost 761 dollars. It's my opinion that nothing more than an internal relay has gone bad and I know for a fact it has happened to others too. My truck has only 35,000 miles on it and shouldn't be presenting costly repairs like this while I'm still making payments on it and have babied it in the 13 months that I've owned it. If these modules are failing at the rate that it appears they are then chevy should recall them or come up with a less expensive solution like an external by-pass type relay that wouldn't involve replacing a costly module like this over some 5 or 10 dollar relay.

The abs & brake warning lights sporatically illuminate while driveing and will sometimes reset to normal after you shut engine off and remove key. This has continued for 2 or 3 months. Last week it finally went on and remained on and would not clear. I took the truck to the mechanic and his diagnostics indiacted a faulty ebcm. I have had it changed just today. I have checked with e others who also own this year truck Silverado and they also have had problem. Some have had it fixes and others not. The mechanic said is the abs light is iluminated then the abs is not operatable.

Dt: while driving exactly 10 mph the vehicle's brakes locked up. The consume has stopped driving the vehicle because he is afraid an accident will result. The dealer has not repaired the vehicle but indicated t needed to be cleaned.

I own a 1999 chevy silerado ext. Cab,I'm having problems with the anti-lock brake system it engauges when it is not needed cause the truck not to stop properly. I have to leave the anti-lock brake fuse out to drive the truck.

Driving down the road and felt my brakes shutter than heard a whirring noise and lights started coming on saying my antilock bracks needed service. Was told that my truck needed a new antilock pumpand that it was out of warranty by 3000 miles nothing was done up to this point.

The abs module is defective. The abs pump continues to run after the vehicle is turned off. My family has two of these vehicles and both have had the same problem. What does it take to get NHTSA or gm to realize that this is a safety related problem and do something about it before someone is injured?.

Abs brake failure with only 40,000 miles on the truck. The abs brakes would come on if I went over bumps or railroad tracks, and then I would have to pump my brakes to get them back (or the truck wouldn't stop). Finally, at 40,000 miles my abs light came on, my abs pump came on and would not turn off, and the chevy dealership told me my abs module blew. I was quoted $1,200 to replace it. Instead, I pulled my abs fuse and operate the vehicle without abs brakes as I refuse to pay for what I believe is a defective abs system. It is my humble opinion that chevy should recall and replace this defect.

Purchased 99 Silverado in Aug 2004, with only 22600 miles. Within 1000 miles my abs light came on, with a loud humming sound from under my truck. My abs module failed. Cost to replace just the part exceeds $800. 00. Gm say there is not a recallable issue, but every dealer/service dept I talked to stated it was a common problem. I do not have the money to replace it, abs fuse was removed so that the pump would not burn up.

The electronic brake control module is failing on my 2000 Chevrolet Silverado which causes a failure in the abs. I contacted Chevrolet and only offered 20% cost assistance even tough this appears to be a very common defect in gm vehicles.

The abs controller failed which allows abs pump to run continously. Must pull abs fuse to stop pump. Lack of abs system in pick-up truck very unsafe due to weight distribution. Have read many similar complaints specific to this model. . Read more...

Abs control module failed at 31,000 miles. Part alone is over $800. 00. Dealer apparently unwilling to do anything . Never buy a gm product again!! buy imports, they make better cars and provide superior service by far! when someone dies due to this problem, hope gm and NHTSA get the hell sued out of them for doing nothing to take care of a very serious safety issue that exist and both parties have known about for some time. Question to NHTSA! if I check fatalities box as 4 people dead!! then will you act???.

1999 full size Chevrolet truck-- frequent abs brake failures causes vehicles not to stop at low speeds problem could cause serious or fatal injury to individuals in parking of crosswalk instances.

Abs control module failed, price to replace over $800. 00 and parts only available from dealer. Numerous posts in internet message boards about same defective parts. Have contacted gm at least twice by email. Abs has been inoperative for at least 6 months.

Anti-lock break system failure on my 1999 Chevrolet Silverado pickup.

Abs and brake light turn on. No crashes or injuries yet. Gm knows of module problem but says item is not on recall.

The abs pump keeps running after the truck is turned off. Pump gets very hot and could cause fire. I had to unplug it to keep from overheating and in doing so I lost the anti-lock brakes. Now gm is going to take me for about $1600 for a problem they know they've had with this. This should be a recall.

After work today, I started my truck, the abs light went on, and a loud noise came from underneath the driver's side. I called my gm dealer, and he told me it was the abs module. He said a new one would cost from $400-500 dollars, plus an hour of labor. I bought it in July of 2003, spent a lot of money on accessories, and paid it off last month. Just after the dealer's warranty ran out(2300 mi), I now have an expensive repair. After much research and talking with parts supply companies, this is an on going problem. When will gm make ammends with their consumers? I am presenting 12 pages of documents to my dealer. Who knows, maybe they will admit there's a problem.

Abs module failure. Continues to run after truck is shut off.

Abs comes on and stays on. When ignition switch is turned off the montor on the brakes continues to run. The only way to stop it is to pull the fuse.

The service abs light on my 1999 Silverado went on, and I noticed a humming noise coming from under the driver side of my vehicle. I traced the noise to the abs control unit. The pump on this unit would continue to run after the ignition was turned off. The only way to stop the pump from continuously running was to remove the abs fuse which disables the abs braking system. I contacted gm but they're advice is to take to a dealership for repair. In the meantime, I am operating the vehicle with abs disabled.

I have an 01 Chevrolet Silverado with an abs problem. The motor or pump activates prematurely and way too often. It has been worked on ,at a GMC dealership, three timesthe first inccident happened in a walmart parking loti was turning into a space when the abs motor just took off. I wasnt going to get stopped,my wife screamed, I threw the gear selector into park. I hate to think that if my wife had been driving and there was person in front of us instead of a parked car what might have happened. Thank you gm for caring about americas safety.

Abs module runs contiually. Electronic brake control module attatched to the abs pump malfunctions, causing the pump to run continually, even after the vehicle has been switched off. Local dealer is aware of problem, and has seen it before on several occasions. Local salvage yards can't keep parts on hand because of high demand. There is no recall!!!!!!!! why???.
