Two problems related to brake abs warning light have been reported for the 1999 Chevrolet Tahoe. The most recently reported issues are listed below.
I purchased this vehicle from my nephew on 11/30/07. Since then, at least a dozen times, the brakes pulsate at very low speeds. An online search seemed to indicate this is a problem with rust or dirt causing the abs sensors to register incorrectly. On 12/05/07, I took the vehicle to a dealership to have the abs sensors and ring cleaned. I was informed later that 3 of the 4 sensors were electrically bad and needed to be replaced and it would cost almost $800. The abs warning light has not once come on to indicate there was an abs problem. Gm should be required to recall all vehicles suspected to have abs sensor/ring problems and vehicles in which the abs warning system does not function correctly.
1999 Chevrolet Tahoe experiencing problems with the brake equipment. The abs activated at low speeds and while on dry pavement which reduced the braking effect and increased stopping distance. The abs light now remains on while the vehicle is in motion. The dealer suggested that the abs module be replaced after the first attempt to clean the corrosion on the electrical connector did not work.
