Brake Antilock Wheel Speed Sensor problems of the 2001 GMC Sierra 1500

Abs message light came on consistently and due to the safety issue explained by my mechanic shop, I had the wheel speed sensor changed and now about 6 months later the abs message light is now appearing in the message board again intermintently. I read where GMC started a recall on September 22,2005 for this same problem which called( gm recall # 05068) but only for "salt belt states" "service brakes, hydraulic:antilock". Interestingly my state was left off of the list. I called GMC and they indicate there was no such recall and suggested I call NHTSA. I have now noticed that my brakes lock up and do not have the antilock system operating.

Braking system began failing at low speeds (< 10 mph), almost causing me to rear end vehicles when trying to stop. Took the vehicle to a dealer, who cleaned the wheel speed sensors at a cost of $110. One month later, the brakes began failing again and after researching on-line, found a gm recall for 1999-2002 GMC sierras. Contacted gm but was informed only vehicles with certain VIN #'s are included, and mine is not one of them. I have children and frequently drive in school zones around school buses and children at low speeds (<15 mph). This is a very dangerous situation because the vehicle will not stop.

2001 GMC 1500 sierra 4x4 currently has 68k miles. Vehicle speed sensors causing abs brake activation at speeds below 12mph. Vehicle was repaired originally on 2/28/2005 for this condition. Vehicle is having a reoccurance of this currently noticed on or around 10/2009. Vehicle was brought into a dealership for diagnosis and it was diagnosed that senors are in need of complete replacement, however general motors has stated they will not replace the sensorts and a recall has never existed for said vehicle (ref NHTSA recall# 05v379000). General motors contact that stated this recalll did not exist. Currently, the failure has not been repaired, and old parts are available. This condition occurs 95% of the time when braking below 12mph, and makes it extremely difficult to stop the vehicle at intersections, traffic, etc. Looking for gm to correct this problem before any accidents or injuries occur. Also parking brake has never sufficiently held vehicle as it gets depressed to floor and vehicle still can roll, promoting a hazard to others in the vicinity if the transmission lock gives out.

The contact owns a 2001 GMC Sierra 1500. The contact stated that the antilock brake system pulsates between 1-5 mph when the brake pedal is depressed. The dealer stated that there was a recall; however, his VIN was not included. At another repair shop, the contact was charged for a diagnostic and was informed that the failure was due to a defective antilock brake sensor. The vehicle was taken to the mechanic and they stated that there was failure with the wheel speed sensor on the front end of the vehicle due to corrosion. The recall number was unknown. The failure mileage was 27,000 and current mileage was 33,000. Updated 09/13/08. At speeds below 10 mph, the abs activated, not allowing the vehicle to stop at the proper distance. Updated 09/17/08.

Had a recall on my 2001 GMC Sierra 1500 series pick up truck for front wheel speed sensor. After they replaced it my anti lock brakes started engaging at speeds below 5 mi/hr. Not always but frequently. Especially in bumper to bumper traffic or coming to a slow stop.
