Brake Sensor problems of the 2006 GMC Envoy

While attempting a full stop after pulling into parking lot, vehicle would not stop, abs came on and prevented Envoy from reaching full stop. Had to put vehicle in neutral and use e-brake. Occurred 4 more times before I could take for service. Mechanic diagnosed issue with abs sensors, although sensors did not report as faulty. Online research indicates this was a common gm failure from 02-08 in trucks in areas where salt/snow is prevalent. Remedy was disable traction control and abs, cant afford to replace front bearings and rear sensors. Problem only occurs intermittently, and only when attempting stop from low initial speeds.

I was driving our 2006 GMC Envoy denali at about 45 mph when the left front abs activated. It was an unnerving experience and happened several times. I had the sensation that the vehicles was instantly pulling to the left with the abs dragging the left front brake. I took it to the dealer who cleared 5 codes related to the front abs sensors and braking system. . Read more...
