ABS comminced during normal stopping conditions resulting in the car not even slowing down even though I continued to apply steady breaking pressure. I purchased my car at beck and masten but ernie guzman Pontiac service dept is examing my brakes, found uneven rotor on one break but does not beleive this is the cause of ABS break problem. My GMC file # 99053279. The service mgr. At ernie guzman Pontiac (phone 281-493-1500) who is looking into the dilema is craig abbondola. A computer check and test drives has failed to shed light on the problem so far. It has only happened to me twice in some 27000 miles of driving this car, but really gets your attenion when it occurs, so far no damage has resulted but that is only due to good luck - so far at least- both occassions at about 30-40 miles/hour in approach to traffic signal.

Consumer has taken vehicle to dealership six times for same problem. There is a grinding noise whenever applying brakes, if braking under 15 mph the noise will be very low, but noticeable. Also the noise will progress as the day go on. *akwhen driving at higher speeds the noise sounds like a bag of bolts. Dealer changed brake pads twice, sand them, grind down the rotors, called GM technichian and the problem still exists. Consumer is leasing vehicle and would like to speak to an engineer as soon as possible.
