I have had consistent problems with the ABS on this vehicle. I have had it diagnosed at chevrolet dealers and independent dealers in va. I have replaced all wheel hub/bearing assemblies. That is not the problem. The problem is with the ABS wheel sensor wiring harnesses. It is obvious if you go online and research this issue there is no way that chevrolet is not aware and the many models of vehicles that are affected. I contacted chevrolet and they have no desire to attempt to help with repairing this safety issue that is well known by dealers, mechanics and consumers. There are currently no tsb's or recalls for this issue. Thanks

Abs, trac off lights come on and stay on and service traction control warning comes on. Took to mechanic, replaced both front wheel hubs not even 6 months ago and now back at shop again to have them replaced. But even having those fixed lights still remain on.

I have a 2001 chevy monte carlo ss. I recently started getting a service traction control light coming on. Also, my ABS would engage at an inappropriate time. I would be easing to a stop and the ABS would kick in for no reason. I took it to the dealership and after paying about 1,000.00 to have the speed sensors replaced'.I have the same problem. After doing some internet searches I have found 'thousands' of similar complaints. Apparently it is a problem with the wiring harness that is incidentally a much less expensive fix. There are consumer reports of their ABS engaging at high speeds for no reason. I see this as very dangerous.

Tl*the contact owns a 2001 chevrolet monte carlo. When the contact started the vehicle, he noticed a warning message indicating service traction system and ABS failure. The vehicle was taken to a local repair shop, but the cause of the failure could not be determined. The technician flashed the computer system to clear the code. The vehicle has not been repaired and the failure persists. The contact researched the failure and was able to determine that the wheel sensor on each wheel, ground, control system, or a faulty wiring harness could be causing the failure. The contact is in the process of taking the vehicle to the dealer and notifying the manufacturer. The failure mileage was 140,000 and current mileage was 153,000.

Stop & go driving. Abs warning light comes on, traction control turns off, service traction control warning light comes on, brake pedal vibrates. All lights stay on while driving but reset after ignition turn off/ turn on procedure as described in owners manual. Next day, same lights & warnings. Take vehicle to dealer on 4/05/06. "computer checked system codes p1189, p0135, c1216 in system. Items tested per trouble tree. All items test good." no charge. Next day, 4/6/06, same warnings! Take to dealer again without resetting warnings. No computer system codes showing, but no input signal from right front hub. Dealer replaces right front hub assembly - cost $479. Vehicle seems fine, until about 4/20 when brake pedal vibration comes back and warning lights come on and off. I turned off the traction control system and everything was fine for several days. On 4/25, with the traction system off, the pedal vibration was back and the ABS & traction control warning lights came on again. Went back to dealer. Although they told me the computer check show codes of c1222 and c1226, the codes do not show on my invoice. Code c1226 appears on the federal safety agency technical service bulletin item number 10017271 for my year and make of vehicle. However the service bulletin number 3500 is not know to the dealer as a valid tsb number, and they could not locate any information about it. Dealer "diagnosed and replaced ebtcm, and programmed system" - cost $697. I feel that by replacing the "brain" (ebtcm) and programming it, the dealer and/or the manufacturer may be covering up a potential safety issue with either one or both systems, ABS and traction control. I also feel that the dealer put me and my family in a dangerous position by failing to diagnosis any problems on the first visit, and then doing it again by making me feel safe by paying for a replacement part that has nothing to do with either system!

Dt: febuary of this year ABS traction sensor and brake system warning light illuminated. When backing iout of driveway or in normal driving at any given speed the brakes would grab and the traction active lights would illuminate. Took vehicle to a dealer, they said it was the left rear wheel hub sensor that failed, but could not duplicate problems consumer was having at that time. The dealer did not replace this, but did reset the sensor. When vehicle was driven away from dealer brakes still had the same problem. Within 24 hours the same issue was actived on the vehicle. Returneds to dealer, this time they replaced the left rear wheel hub sensor. About a month later this happened again. Did phone dealer about this. Consumer made another trip to the dealer, who noted again the left rear wheel sensor had gone bad again. Currently, car is again at the dealer for the 4th time for the same problem. The last occurrence was at a at stop sign, and when applying brake pressure discovered no brakes. Afterwards, immediately drove to dealership, where car is now. Also has had rotors resurfaced, and replaced rear brake pads as well during this process.

While applying the brakes pedal vibrated, resulting in less braking power due to ABS braking system failure. Dealership was aware of the problem because vehicle was towed to dealer for the same problem twice.
