Mine's a 2001 Silverado Z71. Every two to three yrs the ABS sensors screw up. There was a recall on this about 5 years ago which I got done twice...the first time I paid myself about $400.00 then was reimbursed by GM about a yr later. The problem happened again 2 yrs later and GM paid for it(recall). The third time it happened about two years ago they refused to fix it, so they were in fact making me pay for their bad sensor design. Other than that, the trucks been reasonably reliable(recently the electric window gear disintegrated on the drivers side). I feel they should have redesigned the sensor, as my brother had the same experience with his '05(Sierra not Silverado as posted earlier). I think the sensors get corrosion from the salt in the winter and foul up, I'm not sure, but it can lead to a very dangerous situation.
