Driving slowly up to a stop sign coming out of the target store in shoreview, minnesota. The ABS anti-lock brake system activated and made the truck difficult to stop. The vehicle went through the stop sign but did not collide with any oncoming traffic. According to many other incidences described online, the exact same thing is happening to others. In the northern "salt belt", rust and corrosion gathers around the front brake sensors and pulls them upwards sending the wrong signal to the computer. There is already a recall on some chevrolet trucks pre-2005 for the very same reason. This is a very dangerous situation and preventable if gm would solve the problem once and for all.

Brake lines had corroded and a pin hole leak allowed brake fluid to leak out of the system when the brakes were applied. Braking ability was greatly reduced. I was towing a boat at the time, making the failure even more dangerous. Inspection subsequently showed that all four lines which run forward from the ABS module to the master cylinder had several areas of severe corrosion. All the lines needed to be replaced. The use of carbon steel brake lines was a poor design decision. Gm has subsequently in 2008 upgraded the materials of construction, but owners of older vehicles are at risk, and subject to an expensive repair bill.

Abs unit on front brakes malfunctions at low speed. The ABS sensors mistakenly releases brake pressure, as vehicle slows to a stop, thinking the wheel is skidding. This release of brake pressure lengthens the stopping distance, which could result in a low speed crash.

Tl* the contact owns a 2007 chevrolet silverado 1500. The contact stated that if the vehicle wsa driven under 10 MPH, the ABS function activated and the wheel speed sensor failed by not detecting the wheels turning. As a result, the vehicle made a noise and jerked forward without warning. The contact had to apply force to the brake pedal to stop the vehicle each time the failure occurred. The vehicle was taken to the dealer who cleaned the wheel speed sensor. Years later, the failure recurred. At a low rate of speed, the brake pedal was slow to respond and required great force to stop the vehicle. The vehicle was inspected by an authorized dealer again and, an hour later, indicated that they were not able to get the wheel speed sensors removed to clean them. The wheel sensors were placed back on the vehicle. If they were damaged, the contact would need to replace the wheel speed sensors, if they were damaged. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 24,000.

When I am applying the brakes, at about 10 MPH, the ABS kicks on and keeps the truck from stopping. The driving conditions haven't mattered. The roads are dry and there is no indication on the dash that there is a problem. It is happening pretty consistently at slow speeds.it seems to be a problem with the ABS speed sensor on the drivers side.

While driving at different speeds door locks will cycle on and off, exterior lights and dash display will go off, wipers will freeze, all gauges will go zero and two or three warning lights will come on such as stabilitrak, ABS brakes or service air bags.

When driving the truck the lights would dim and then have a loss of power. Didn't think much of it until one day getting out of the vehicle and shutting it off I went to put the key back in the ignition and there was no power what so ever no dome lights nothing... No clicks no dash lights nothing. Then had someone jump me power and truck started right away. Same day had my battery checked and alternator and everything came out fine nothing was wrong with it. Happened again about a week later but this time truck hesitated when key was turned then it did not start reset the clock in the truck and then had lights dimming everytime blinkers were turned on. Got home and had a feeling truck would not start if I took the key out sure enough everything was dead when I tried turning it back on. Had to jump it again. When that happened I got the battery replaced thinking it was faulty. Two weeks went by and it was fine then after punching on the gas a little to pass a semi the locks went up and down really fast and had lights dim again no message on the dash or anything. I got home and truck did not start again. Jumped it again then a week later going to work on the freeway the truck had extremely bad tremors and then the locks started locking and unlocking again the lights and stereo were going on and off and ABS light came on and vehicle kept going into neutral and drive every other few seconds witch caused a concern for my safety. Good thing I was only a few miles away from home. I turned around went home and sure enough turned it off put the key back in and no power . Explained failure to a dealership and said possibility was the ECM. And they could do nothing unless it was duplicated.
