One problem related to brake sensor has been reported for the 2003 Chevrolet C1500. The most recently reported issues are listed below.
Anti-lock brakes on my 2003 Chevrolet silverado pickup VIN # 1gcek14x332193001 do not work at low speed. I have had this truck back to the dealer in somerset PA where I bough it and they have failed to repair it. The first time they said that was the nature of anti-lock brakes and did nothing. The second time after I almost wrecked the truck they cleaned the abs sensors and said that was all they could do. The problem is still there. I wanted them to unhook the anti-lock brakes but they would not do that. This all took place over the last two years. Now gm is recalling 1998-2002 silverado pickup for anti-lock brake problems but not my 2003 truck. My truck was built in 2002 and I bought it in 2002 but it is a 2003 model. I believe this truck should be recalled and repaired before I get hurt. If gm can't repair this truck they should give me a new one. I only have 8,700 miles on this truck and I bought it for bad winter roads and I am afraid to drive it because you can't stop at slow speed on snow or ice roads.
