Engine Cooling System problems of the 2003 Mercedes Benz S600

Mercedes benz, s-600 (model 2003), it was very difficult to control the car in the highway and the car almost lost control after it's active body control (abc) light flashed on suddenly in the dashboard and the car body came down grinding against the wheels/tires on 12/03/2009 again after the car's abc system was replaced on 11/19/2009 at mb dealer in edison, NJ. I have reported safety complaints on this car about abc system quality problem (odi number 10294645). The car was sent to mb dealer in edison, NJ for checks at same day and they found that the engine water pump dead and made engine belt broken and abc system at malfunction. I feel the abc quality problem has affected engine water pump's quality. Abc system malfunction is safety consideration. It looks like mb has a incorrect design of engine water pump and abc system for s-600. Please investigate and consider this issue for a new recall. Thank you.
