Brake Antilock Control Unit/module Problems of GMC Sierra 1500

The contact owns a 1999 GMC Sierra 1500. While attempting to stop the vehicle at a low rate of speed, the abs engaged and the vehicle could not be stopped until the brakes were disengaged, engaged, and pumped. On September 4, 2003, at 46,663 miles, the failure occurred, but only one sensor was replaced at that time. On September 20, 2004, at 54,318 miles, the failure recurred and a second sensor was replaced. A recall was issued and the vehicle was repaired accordingly on February 21, 2006, in which both sensors were replaced at 58,869 miles. On March 3, 2006, the contact retrieved the vehicle, but it had been crashed into the wall. The mechanic replaced the front passenger side hub, which was claimed to have caused the crash. The front end of the vehicle was poorly repaired. In March of 2008, the abs failure recurred and the contact took the vehicle to be repaired again, but was informed that it was no longer under warranty. The contact disconnected the abs. The current mileage was 95,500 and the failure mileage was unknown.

: the contact stated while backing the vehicle out of a parking space, a humming noise was heard. While driving the vehicle 50 mph, the noise continued. The contact determined the humming noise was the brake module pump running and disconnected the pump until the vehicle could be taken to the dealership. After the engine was turned off, the humming noise continued. The dealership confirmed the humming noise was coming from the brake control module and there was either a faulty electronic computer relay in the brake module or in the valve body of the brake module. Updated 10/18/2006 - the consumer is concerned that the brakes may fail.

On my 2001 GMC sierra truck the warning lights came on for the abs and the parking brake I took it to the mechanic and was told the ebcm (electronic brake control modul) needs replaced. I spoke with the mechanic and he pointed out that there is a lot of these being replaced on this year of vehicle.

: the contact stated while driving 25mph the abs light illuminated. The vehicle was pulled off the road without incident. The brake fluid was checked and then the vehicle was driven to the contact residents. When the vehicle was tuned off, the abs modulator was observed to be still running. The fuse to the modulator was disconnected and taken out. The dealer stated the abs modulator needed to be replaced. The manufacturer has not been.

: the contact stated while traveling various speeds on dry normal road conditions, the antilock braking system activated and pumped continuously when the brakes were applied. Shortly after, the abs warning light illuminated. The failure occurred while cruising. There were no warnings prior to the incident. A NHTSA recall regarding the speed sensors, was performed two weeks prior to the incident. The vehicle was taken to the dealer who determined that both problems were not related, and a diagnostic test displayed that the electronic control module was faulty and would need to be replaced. There were no repairs made. The contact removed the fuse that supplied power to the electronic control module in the mean time, which deactivated the abs system. The contact planned to file a complaint with the manufacturer after filing a complaint with the NHTSA. Updated 1/19/2007 -.

1-I noticed brake failure at slow stopping speeds and the abs warning light stayed on. 2- this caused a few close calls as far as almost hitting structures or vehicles directly in front of me. 3-took to the dealer and was told it was the wheel speed sensor located in the wheel hub and replaced at a cost of $500. 00 plus . Also found out that this is a recall for east coast only recall # NHTSA id # 05v379000. Because this is a defective part on east coast I feel it should apply to my vehicle as well even though I'm on the west coast.

The computer that controlled the abs failed and as a result the system did not function properly.
