Brake Electric Antilock problems of the 2000 GMC Sonoma

Abs & emergency dash lights will turn on/off intermittenly; no pattern as to when/how often. Had gm dealer check it. My ebcm had a short, if lights were on, had no abs, just hydraulic if lights were off. I have abs. Cost of new module is $1100. 00; plus labor!! dealer suggested I live with it for cost of repair! I agreed, but worried that gm probably were ignoring lights & thinking they had good abs!!.

: the contact stated while traveling 35 mph the contact depressed the brake pedal and it went to the floor. As an attempt to stop the vehicle the contact pumped the brakes. , resulting contact in a rear end collision. This incident occurred on wet road conditions. The vehicle was towed to an independent towing service.

After depressing brake pedal to make a stop brake pedal pulsated. This resulted in extended stopping distance.

While driving 2 mph applied brakes, and pedal vibrated and went to the floor, no braking action. Vehicle hit garage wall. No injuries. Please add further details.

Brake pedal almost goes to the floor causing extended stopping distance. Dealer has replaced master cyclinder which did not correct problem. Please provide further details.

While traveling 35 mph and approaching a stop light tried to slow down and brakes did not respond . Vehicle did hit another vehicle, driver was only person in vehicle driver was wearing seatbelt. Accident did occur with injuries.

Anti lock brakes are inoperable. Dealer has been contacted. Please provide furthr details.

While trying to stop at slower speeds pedal will go all way to floor. Once pedal reaches floor there is no brake function left. No accident or injuries have occurred.

While consumer was driving at 40 mphvehicle died out. Towed to dealer. Dealer noticed that fuel pump needed to be replaced. This will be the third time.

Anti-lock system defective in strategy of operations. Seems designed for icy roads and activates under the lightest of braking applications on front wheels with 1-2 second recovery time (without brakes) with only slight pedal & slight wheel bounce. This happens with 1-2 passengers & about 75-100 pounds in truck ped (bed cover) on dry streets approaching intersection with ripples or potholes on one side with very light slow (grandpa style driving) light braking- front wheel senses the slightest lockup & deactivates brakes (1-2 second recovery time) & then reapplies. This has resulted in multiple times of leaving me in intersection with vehicles skidding to stop to keep from t-boning my vehicle. Have complained to dealership management, gm district field rep who tell me this stratedgy is normal. This stratedgy will get people killed if it hasn't already. They told me there is nothing they can do. This report is being made to hopefully force something to be done. I could do better job of preventing brake lock up using ancient mode of stab breaking if necessary but wouldn't need to under descibed scenario.

Vehicle was involved in frontal collision with a chevy full size pick-up at approximately 20-25 mph. Both abs/air bags failed to operate/deploy. Vehicle left a skid mark of 20 feet or more. Dealer/manufacturer were contacted.

When driving at freeway speed(70-75mph)/abs & regular brake system warning light comes on/I ask to fix it to my dealer management and gm customer assistance center many times but they said "we can,t".

My 2000 GMC Sonoma pick up abs brakes activate on a daily base. Under 20 mph and on dry pavement. When they activate they pull to the left that the right. Did they use the wrong tires?.

Anti-lock brakes engage and pulsate to slow down but not stop when going over bumps on paved surfaces. Includes all speeds. On one occasion this caused me to proceed an extra estimated 15 feet into an intersection where an accident occurred. Dealership and manufacturer contacted and system checked. Was not satisfied with the inspection of the braking system. Since this incident, this has happened again, although with no resulting consequences.

When applying brakes abs system activates too quickly, causing a collision to occur. Please give any further details.
