Brake Antilock Wheel Speed Sensor problems of the 2000 GMC Yukon

When slowing down at an intersection stop light, at the speed of under 10 mph, the abs brakes suddenly kicked in and pulsated, not allowing the truck to stop. This almost resulted in a rear end collision with a stopped vehicle in front of me. After pulling into a parking lot the same issue happened again, causing me to panic and stump on the brakes hard before running into the parking blocks in front of a business. After taking the vehicle to the mechanics they could not diagnose a problem. Even though there was no abs warning light or error code, we elected to replace both abs speed sensors as a precaution. The problem still existed. I decided to have both front and rear brakes including rotors replaced as a precaution. The problem still accures with every slower speed attemp to stop. I am very reluctant to drive the vehicle and when I due, I have to begin my braking well in advance and at a increased distance from where I would like to stop.

The contact owns a 2000 GMC Yukon. The contact stated that the abs system activated independently while driving 5 mph, causing an increase in stopping distance and time. The contact had the vehicle serviced under NHTSA campaign I. D. Number: 05v379000 (service brakes, hydraulic:antilock) but the repair did not remedy the issue. The contact had the wheel speed sensor twice but it also did not correct the issue. The failure mileage was 82,000.

The speed sensor fails at speeds between 6 and 9 mpg; resulting in no or limited ability to brake. Repeated near accidents have occurred in traffic and in parking situations. The vehicle is being repaired at this time at jim murphy pontiac-GMC truck, inc. 3000 walden Ave depew, NY 14043 phone: 716-684-8900 fax: 716-684-9050. I understand gm has recalled practically identical vehicles such as the gm tahoe, suburban, etc. My understanding is that the GMC Yukon denali is virtually the same vehicle as the gm tahoe. I would like to understand why that recall is not applied to the GMC Yukons.

My 2000 GMC Yukon denali is experiencing problems as described in recall 05068 from GMC. GMC has told me that my vehicle falls under the right time frame but does not fall under the right VIN numbers. I am having the exact same problems! the following is an email that I received from GMC: vehicles of a model year are affected. There is an upcoming recall 05068 front wheel speed sensor- description: abs wheel sensors. General motors will notify all owners of involved vehicles beginning 10/12/2005. Please make sure the local department of motor divisions (dmv) has your current information for mailing purposes in case your vehicle is involved in the recall. Below are some information that may be helpful for the upcoming recall. Description of condition: some of the subject vehicles may experience extended stopping distance associated with unwanted anti-lock brake system (abs) activation during low-speed brake applications (less than 10 mph and greater than 3. 7 mph). This condition does not set any abs codes nor does it illuminate the abs warning lamp. This condition is more likely to occur in environmentally corrosive areas, based on field report data. Consequence of condition: when the peak-to-peak wheel speed sensor voltage level received at the abs controller is below the minimum specified peak-to-peak level, the abs controller interprets this as a wheel speed that is less than the actual wheel speed. In other words, the abs interprets the wheel as slipping when it is not. If the brakes are applied, an extended stopping distance may be required.
