The contact owns a 2004 Chevrolet Suburban 2500. At low speeds, he would depress the brake pedal but the vehicle would not respond accordingly. It seemed that the ABS would activate and cause him to move a few feet forward. The ABS also increased the stopping distance and almost caused the contact to crash on two occasions. He took the vehicle to the dealer but there were no codes produced. The vehicle has not been repaired to-date. He called the manufacturer and asked if they could include his vehicle in recall 05V379000 but was informed that his model year was not included. The current mileage is approximately 80,300. The failure mileage was approximately 76,000. Updated 2/22/10 updated 05/17/10.

Update to prior complaint based on additional information. Have discussed this with D boyd. 2004 Suburban failed to slow during hard stop between 40 and 20 mph. I believe that my original conclusion is probably accurate given that the 2004 Cadillac srx ABS ECU and the international ABS ECU failures were within the time period my Suburban was manufactured. This happened once before and occurs during wet conditions after two consecutive brake attempts. GM is stone walling me but I'd like to handle this without getting clarence ditlow @ the center for auto safety further involved. I've had problems with hendrick Chevy for almost a year now including a defective engine on 1996 Tahoe, defective brakes, suspect emissions testing dtc P302 cylinder 2 misfire, possible incorrect transmission replacement, possible failure to replace passenger seat which I believe was recalled and posed a danger for almost 4 years, dex cool gasket blow out, steering column lockup etc. I requested a police report from the nc dot and for some strange reason it's not on file although I have the receipt from the officer. VIN # on the Suburban was 3gnfk1674G131855 manufactured @ the silao assembly plant on 9/13/03 @ 7:10:31. Shipped to 16153 hendrick chevolet-Hummer 100 auto mall dr cary nc dealer order number gmngbb charged to zone: 16 dealer: 153 pui: 04203173688.

Brakes failed to slow 2004 Suburban during low speed braking in wet weather causing a collision. ABS module is not working correctly in wet environment during a hard stop. I have owned several SUVS and have never seen this problem in the others. I have the full dump of the obd speed plots just prior to the crash.
