1999 BMW 540IAT User Comment / Complaint

Complete abs failure while traveling at speeds. the abs control module controlled each wheel differently at different times, causing the car to buck wildly at highway safe speeds. while braking, the controller went bad (was reported to dealer previously and told it was the brake pads - changed and still had issue) , locked up the rear wheels, caused sliding condition in traffic, nearly colliding with other cars and underpass barricade. this has happened numerous time and has been reported to dealer (none at speeds - 10 mph or under - controllable at those speeds).
