GM 1999 Silverado anit lock brake unit would not shut off even when truck was shut off. I tried to disconnect battery and burned fingers. To correct the failure pulled the fuse, but brakes do not stop good I have to press real hard to stop. The problem with the ABS brake is that the pump motor is producing voltage spikes and the amplifier shorts and won't shut off drawing high current and anti lock brake failure and over heating of battery terminals causing burns when touched. This was so hot that the post came out of the battery. To correct the problem GM needs to change the amplifier to original failed 75 amp pump motor power amplifier with a double duty rated 104 amp (360 amp surge) device. Add a 600 watt high speed voltage suppressor to protect the ebcm and the new amplifier set from voltage spikes created by the pump motor and jump starts. I have not had this fixed on my truck because I have been waiting for a recall. When are you going to make them fix this. You have many listing of this failure on your site. Listed as brake lights on, ABS etc. Ebay now has people who fix these modules one has over 400 satisfied customers. I this this may effect million of trucks. Incident date I would have to check for actual date.

Loud humming from under drivers side of truck with engine off. ABS light on when truck started. Pulled 60 amp fuse for ABS to stop humming. Problem seems to be corrosion on a circuit located under the truck. ABS now not functional and brake warning lights stay on after fuse was pulled. Vehicle now without antilock brakes. * faulty connection happend about 800 miles over extended warranty and dealer would'nt even discuss covering it.

ABS system on the vehicle is not working properly due to a faulty module. Dealer was notified.

Loud humming from under drivers side of truck with engine off. ABS light on when truck started. Pulled 60 amp fuse for ABS to stop humming. ABS has performed erratically over life of truck, including not stopping numerous times on bumpy road surface. Apparently General Motors is aware ofissue with faulty design of unit, but refuses to accept responsibility. Will they accept the responsibility when someone dies becuase of their neglect" will the NHTSA accept responsibility for not assisting in the protection that they say they are providing? why are failing components of this magnitude allowed to remain on these vehicles without any justification"
