Four problems related to brake antilock wheel speed sensor have been reported for the 2000 GMC Safari. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2000 GMC Safari based on all problems reported for the 2000 Safari.
: the contact stated while applying brake pressure at 10mph or less, the antilock brakes pulsated which increased stopping distance. The vehicle was inspected by a dealer who was unable to duplicate the problem. The vehicle was taken to an independent repair shop who determined that the wheel speed sensor needed to be replaced. The problem was corrected after replacing the wheel speed sensor.
: the contact stated while applying brake pressure at low speeds of 5-10 mph the abs activates and there is decreased braking power and the pedal pulsates. There was an accident relating to this. While parking the vehicle, when applying the brakes, the vehicle rolled off of the parking area and down the hill and hit a tree. There was property damage. There were no injuries and a police report was not filed. The vehicle had to be towed to the dealership and is awaiting inspection. In 2003 with 75,000 miles, the vehicle had the same decreased braking power. At that time, the dealership replaced two front abs wheel speed sensors.
The brakes on my year 2000 GMC Safari passenger van failed while I was coming to a stop and an intersection. I was traveling at approximately 10 mph. I narrowly avoided a collision by turning onto a grassy median. The brake pedal pulsated several times and the pedal then dropped. I could not stop the vehicle using the brake pedal. The van is well maintained and has 36,000 miles logged. The repair shop diagnosed the problem as a failed wheel speed sensor. The hub and bearing assembly and the speed sensor were replaced. It has now come to my attention that a recall is in effect for this part - front hub/bearing assembly and the wheel speed sensor - on 2002 model year chervrolet tahoe vehicles (letter dated October 2005 from Chevrolet). I strongly recommend investigating these questionable parts on all gems vehicles. It is my belief that the current tahoe recall should be expanded to all vehicles with these parts.
The contact stated the abs sensor and hub bearings had to be replaced. The abs was activating at low speeds at 5 mph. This has been a problem for the past year. The abs light on the dashboard kept coming on. She has taken the vehicle to the dealer once. The dealer replaced the wheel speed sensors on the front of the vehicle. There had been corrosion in the bearings. The vehicle was repaired at the contact's expense. . The manufacturer was not contacted.
