I was parked idling when the engine went out. Cooled down and started. Got on 10 at 60 mph and the ABS brake light came on and the speed dropped instantly to about 30 mph. Twice on the way home did the same, then conked out. Tried to drive to shop and had to be towed. They replaced the cam sensor and acts mostly okay. But every so often the ABS light comes on and the speed drops dramatically then recurs. There is not a code being put in the system telling them the issue why but there was a code one ABS sensor is turning on. It is like the ABS is engaging without me hitting the brakes and then cutting off. Again this only happens sporadically will be taking it into the dealer asap. Note again no indicator the cam sensor was bad or anything else. Updated 08-20-14 the dealer stated there was a code in the system, for the speed sensor, and they were able to clear it.

The antilock brakes on my Chevrolet S-10 pick-up fails while trying to stop in bumper to bumper traffic of between 15 to 20 miles an hour fortunately I ran into the back of a full size Chevrolet truck and there were no injuries, only damage to the vehicles. Prior to this incident for about a month the brakes would pulsate after driving a a while and stopping at low speed or during light pedal pressure. The brakes were check for warped or defective rotors and possible worn pad. The rotors and pads were found to be ok and so were the rotors which are smooth. The brake pads and rotors are the factory originals and the vehicle has under 36,000 miles. The truck is use as an occasional local commute vehicle and for pleasure, and not for work, or to carry heavy loads. After I found two 020525006A and 02052500 which describes the problem of low speed ABS activation. I think this is a very serious issues that people should be made aware of. Just as I couldn't stop and I hit a truck, I could easily have hit a person or a child that may have ran into the street chasing a ball. This accident happened just two blocks from my home. I think is negligent that car companies are not made to report to consumers such serious life safety issues, which can cause the lost of life for both drivers and pedestrians, which could be any of us or any of our relatives. When I got home and realized the implication of consumers not being notified of such bulletins I felt sick to my stomach. I hope that General Motors is made to bear the responsibility of not only informing consumers of such a vital safety equipment failure, but also for paying for the repairs of something which could have been corrected while my vehicle was still under warranty.

When I hit a small bump my ABS kicked in and I lost alot of braking power, almost caused accident. Brake pedal went to the floor. (earlier date). Brake pads completely warn down to squelers after 10,000 miles cost of $160 to replace pads.

Intermittently brake light illuminated on the dashboard. As a result, the brakes applied by themselves, resulting in extended stopping distance.
