THE MERCEDES BENZ DEALER INFORMED ME THAT I HAD AN OIL COOLER AND ABC HOSE LEAK ON MY 2001 S600. THE COST TO REPAIR IS UNBELIEVABLE. ABOUT $7,500. IN READING THE MBZ FORUM THIS APPEARS TO BE A COMMON OCCURRENCE WITHOUT ANY HELP FROM MBZ. THE FAILURE FOR THE OIL COOLER LEAK CAN LEAD TO A FIRE, AND THE ABC HOSE LEAK CAN LEAD TO MALFUNCTION OF THE ACTIVE BODY CONTROL SYSTEM CAUSING THE CAR TO DRASTICALLY LOWER AT THE EFFECTED WHEEL. THE FREQUENCY OF THIS PROBLEM SHOULD BE COVERED BY A MANUFACTURER RECALL. THIS IS A DEATH HAZARD TO ME AND MY FAMILY. I AM NOT DRIVING THE CAR AT THIS TIME DUE TO THE COST TO REPAIR AND THE PROBLEM OF INJURY OR DEATH. *TR
