Four problems related to brake sensor have been reported for the 2004 Chevrolet Silverado. The most recently reported issues are listed below.
2004 Chevrolet Silverado. When decelerating to stop for a red light, the abs system activated causing the vehicles deceleration to decrease, thus increasing the stopping distance, resulting in a near collision. The vehicle now does this consistently during every stop once the vehicles speed drops bellow 10 mph. There are no warning lights indicating anything is wrong with the vehicle, which is even more alarming. This problem seems to be identical to that in NHTSA campaign id number 05v379000. If there is an problem with speed sensing (as in NHTSA campaign id number: 05v379000), the system should be able to detect inconsistent sensor readings and render the abs system into a passive mode as a fail safe measure.
The contact owns a 2004 Chevrolet Silverado. The contact stated that the antilock brake sensor indicator illuminates immediately while attempting to stop from 5-10 mph. This is during a soft stop, not a hard stop; therefore, the sensor should not illuminate at that speed. The weather and speed are not factors. The contact paid $90 to have the vehicle diagnosed; however, the failure still persists. The failure mileage was 32,000.
Abs activation at speeds under 20 mph, sometimes jerk the wheel to the right, for no apparent reason. Mechanic replaced abs wheel sensors, problem even worse, and told to bring it to gm.
