One problem related to abs brake fail has been reported for the 2003 GMC Safari. The most recently reported issues are listed below.
I own a 2003 GMC Safari which I purchased in utah. Earlier this year I experience a problem with the abs baking system where the abs would engage at low speeds, increasing my stopping distance greatly. I contacted gm as this seemed to be a safety issue and was told to take it in to a local gm dealership. The dealership inspected the brakes and noted that the sensor was bad and billed me for a repair. I see now that gm has issue a recall, although it does not cover my state or vehicle model, I was experiencing the exact problem that these other vehicles have with the abs failure. I think this needs to be more widely investigated as it seems to be a larger problem then they want to admit. I understand that the problem is caused by products used on icy streets which the van operated on in utah before I bought it. Ps-the dealership destroyed the faulty part even though I asked to see it - they stated that this was there policy.
