I am complaining and asking for further investigation into abs brake activations on my 2001 GMC 1500 Sierra. I read an article that many failures were occurring and that this was being investigated. Gm has recalled vehicles in canada along the "rust belt" I heard. I live in michigan and go through similar weather issues as canada and feel that the brake problems are also the same as the canadian issues. My abs brakes will activate almost daily and my vehicle is just outside of the warranty. I would encourage further investigation into this issue as clearly the same thing that has occurred in canada is also occurring here as well. With the added stopping distance as a result of the abs/brake failures, I do not want to see a senseless accident occur which could cause damage, injury or god forbid any deaths. Please feel free to contact me at home if you need further. Thank you for your time. Marco a. Hernandez olivet, mi (269) 749-9295.
Abs faulty, replaced, now actuates when it shouldnt.
I started up my 1999 GMC Sierra one morning last spring to go to work and when pulling out of the driveway a loud noise started coming from under the cab and the abs light came on. I had it checked out by an independent garage who found it to be the ebcm. The truck had less than 45000 miles on it and had never been off road so it hadn't been mistreated. The module has stayed on and the abs light is on always. I tried to get gm to own up to the faulty part but they refused. I think it is shameful that gm puts low quality electronic parts in their vehicles, and charges so much for the parts. The ebcm costs over 900 dollars which is a lot of money. When you pay over 30,000 for a truck you expect it to last a long time. But gm is not interested in making quality anymore. Gm told me that this was a very uncommon problem, wrong, on the web I found many people have had the same problem and in fact there is a rebuild kit for them. I also had my 4wd control module go out at 140 dollars just to replace a push button.
Nhtsa action # pe05020 - I submitted a complaint (odi id# 10120245) for my 99 GMC Sierra truck last spring for the abs control module failure. You "closed" the investigation on 9/13, and gm issued a recall. The problem is that gm still charged me over $1000 for the replacement abs control module that failed, causing the loss of abs totally on my truck, per my complaint. I would not have been able to get my truck inspected in vt without the abs working so I had to pay up to GMC to replace the module. Was this to be covered or not? if not, why? it seems that this abs module failure is a recurring theme for gm(c) trucks. Please respond by e-mail.
I have a 1999 GMC Sierra half-ton pickup truck with only 29k miles. Last week, on my way to work early in the morning, my abs pump activated, unable to shut off even with ignition turned off. Local garage had to pull power to shut off. Subsequent gm inspection resulted in being told the abs control module was corroded and needed to be replaced at a cost of nearly $1000 dollars, much more if the pump was damaged also. I now have only normal, no abs, brakes. And both abs and brake lights are on in dash. This is a known defect and since canada has recalled for this problem the us should too. Most of us will drive with only std brakes because we cannot afford to pay out a thousand bucks for fixing something that should never have happened in the 1st place. And this is a safety issue here in snow country.
While applying the brakes coming to a stop light the brake pedal went to the floor and got hard. Consumer had to pumps the brakes to get the vehicle to stop. Vehicle was taken to the dealer, and dealer informed consumer that both front wheel abs sensors needed to be replaced.
Anti lock brake ecbm fails, abs motor stays on all the time, loss of antilock function, loss of proportional braking to rear wheels. I suffered a total loss of control on slippery road surfaces, truck spun 360 at slightest touch of brakes told $900 to repair, common failure for this model and year.
Anti lock brake light on and anti lock brake pump will not shut off.
Brake pedal at times will go all the way to the floor, other times it seems like you have too keep pushing way harder than normal to stop almost like something's pushing you. Have been to dealer nine times they replaced the master cylinder twice, now they say the problem is caused by the electronic brake control module and there isn't anything they can do about it.

The abs turns on in my truck while coming to a slow stop causing the truck to not stop. I took upart my hubs, the front abs sensor has corrosion in it that puts it out by a few thousandths and it thinks it is going -5 mph and turns the abs on. This has almost caused several accidents for me as I have rolled right into several intersections when I expected my brakes to stop my truck. Luckily I was quick enough to use the ebrake each time until I could get a temp fix going. The problem is with the sensor, not the abs itself. I am not sure how to correct it, other than cleaning it regularly, so I disbaled my abs (pulling the fuse under the hood) to make it safe to drive the truck in the mean time until a resolution can be found.

While applying the brakes abs brake light appeared on the dashboard and remained on. This caused a loss of brake power. Consumer was able to maintain control of the vehicle, and drove it to the dealer for inspection. Mechanic determined that the brake pressure modulator valve was not functional, and needed to be replaced.
While pulling into traffic at 5 mph abs light came on and stayed on. Vehicle was taken to the dealer, who determined that the abs module needed replacement.
Brake problems/ failure of abs brake system on GMC truck: I just paid over $ 800 last fall to reputable mechanic who told me that all 4 wheel brakes and rotors were gone at 35000 miles of normal on road driving. Now he and another good service garage tells me I have a bad brake module (at 39000 miles ) which is going to cost another $900 or so. Worst of all, research at your site seems to indicate that the brake system has never worked properly and will never have the reliability that I paid ( and am re-paying ) for. The truck is out of normal warranty but I am looking at so called "secret warranties" and complaint sites so that I am well prepared when I visit the dealer ASAP. I hope they are not as disappointing to me as gm is.
Abs brakes goto full release below 10 mph unable to stop.
On 11-15-03 I had the electronic brake control module on my 1999 GMC Sierra go out. Which I found out is a very common problem for these trucks around 80000 miles(mine about 81000) the repair was a total of about $1150. 00. Seven weeks later on 1-9-04 my truck is now in the shop for the same problem(ecbm) plus the abs pump and the dealer now says it will be another $950. It appears that a problem exists when so many people have the same malfunction at almost the same time.
1999 GMC Sierra electronic brake control module malfunction caused abs motor to run after engine shut down. Potential fire hazard.
1999 GMC Sierra 34719 miles I had failure of the electronic brake control module.
My 1999 Sierra GMC truck abs module has gone out, causing me to loose my abs brakes. It costs 829. 00 to fix and in my research I have discovered that it is a defective chip in the module and GMC knows about it but has not issued a recall. My truck only has 63,000 highway miles on it.
