ABS and park brake light illuminated. Result was ebcm (electronic brake control module) bad which I was told by the dealer could cause total brake failure. Repairs cost $959 and according to the research I have done, this is very common around 80,000 miles. Mine is at 83,000!

2001 GMC Yukon ebcm failure. This has occurred twice in three years. The first occurrence was just over the manufacturers warranty period and GMC paid for the part and I paid for the labor only after a multitude of complaints to GMC. The module has failed again. This is a serious flaw and needs to be addressed and the dealer/manufacturer is choosing to put their customers at risk and not addressing the problem.

The brake pedal had become increasingly hard to push over the course of a few weeks. Finally, the ABS warning light came on and the ABS pump ran continually, heating the floor pan of the vehicle. I removed the ABS fuse to stop the pump. This in turn has disabled the ABS and the traction control system on the vehicle. In researching the issue, it seems the repair from GM is very expensive ($1100) and uses the same version of a commonly failing part that might only last another 40-50K miles.
