The problem
Some of these passenger vehicles have an electronic control unit (ecu) that may calculate a higher than actual vehicle speed because of an erratic rear-wheel speed sensor signal, and cause abs activation where it is not needed or needed abs activation to be extended during braking as the vehicle speed drops to about 3 mph.
The risk
Unexpected abs activiation could increase stopping distance up to about 11 feet dpending on the grade of the road, increasing the risk of a crash.
The fix
Dealers will reprogram the abs controller. Owner notification began on june 16, 2004. Owners should contact chevrolet at 1-800-630-2438.
