Abs system fails on panic stops. Suddenly applied pedal presseur locks brake pedal and provides little or no braking for approximately 1 second. I have been told by the dealership's service department that this is typical of all abs and that I need to train myself not to jam the brakes in an emergency. Vehicle was in shop in Dec. 1999 for transmission repair and brakes were supposed to be checked. No check was noted on repair order, but service manager assured me that the mechanic had test driven the vehicle and it was ok. This problem seems to be a result of abs pump overreacting to suddenly applied pedal pressure and locking the pedal with back pressure before braking actually starts. I feel that the brakes should at least chirp the tires first. Currently vehicle is under repair from accident, but it will be taken to another dealership upon completion of this repair.

Being as mr. & mrs. Adkison have no computer and I am the one that discovered the fault with their vehicle, I am submitting this form for them. I am a mechanic of 25yrs experience and I am the one that questioned two of the service writers at two gm dealerships plus mrs adkison was told by her dealership that he had 3 more vehicles with the same problem. My name is david smith (smurfs@bellsouth. Net). I am the transportation supervisor at mrs. Adkisons place of employment. My business # is 318-841-2149. The abs motor shorts out and continues to run untill unplugged or fuse is pulled. It gets extremely hot. It is mounted inside the left frame rail and fuel lines run just over it. The motor could catch on fire and melt fuel lines, resulting in a bad fire. In talking with 2 service writers and 2 different general motors dealerships, I have been informed of a total of 6 abs motor failures due to shorting out and running continuously after ignition is shut off.

The vehicles abs system failed. Nlm.

Anti-lock brakes activate during normal braking in non-emergency situations at speeds under 30mph. Brake pedal goes to the floor making a chattering noise and stopping distance is increased. This problem prevents the driver from stopping vehicle before stricking another vehicle or entering an intersection at the risk of causing an accident. This is not how a "normal" abs system operates and is a serious design flaw that gm needs to address before someone is needlessly injured or killed! I've had this truck for one month and I'm afraid to drive it now because of the faulty abs brake system. The drivetrain makes a groaning sound while in 4wd mode and the truck sometimes doesn't want to move without great effort even on dry pavement. This condition does not exist when 4wd is disengaged. The truck has manual 4wd with 4. 10 rear end with automatic transmission. This problem is not related to the abs failure.

Abs brakes fail when you apply brakes when there is a bump in the road. I have had 14 failures in 2095 miles. The brake pedal drops down slightly and becomes solid, you can not push down anymore and the vehicle glides to a slow stop. It will not stop in an emergency in this case. The problem seems to be in the suspension and the abs brakes. The vehicle vibrates and does not recover fast when you go over a slight bump in the road. At highway speed the whole vehicle and steering wheel vibrates. The plastic hub nuts always come loose when driving.

Abs system failed to work.

Abs brakes failed which caused a crash. Pedal went to the floor when applying the brakes. Problem was reported to the dealership. The vehicle has not been repaired.

While driving down a dirt hill at 3 mph applied brakes, and the vehicle free wheeled down a hill at 40 mph due to the abs system failure. Also, frame is bent.

Ongoing problem with abs system failure. At 2,700 miles 1st incident occurred when applying brakes. Pedal kicked back up, causing momentary loss of brake 90-100 feet before stopping. Dealer notified, and made some repairs. At 28,000 miles, problem reoccurred, and caused a vehicle accident. Notified dealer again, and informed consumer that they were unable to duplicate the problem.

When applying the brakes in a sudden stop, the middle lap seat belt did not lock, causing passenger to move forward near the dash area. Also, car seat in middle rear belt, doesn't lock, causing car seat to fall over, resulting in 2-year old hitting his head. Abs brakes fail, fad eon some stops, will not stop.

2000 GMC Sierra has problems with brake rotors, engine failing to restart, and the passenger cab was not level. Shims were installed to make the cab level. The rear rotors were crystallized and flaking off which caused pulsation while braking. The abs sensor failed which resulted in intermittent brake loss. The gas pedal became stuck at times.

The location of the abs was exposed to debris, which caused corrosion and resulted in abs failure. The consumer had to unplug the abs as a temporary fix to the problem. The dealership been notified.

While driving abs light would come on, and then brakes would go to standard brakes. Abs pump would fail to work. This does not prevent vehicle from skidding. An independent mechanic checked brakes out. Please describe details.
