NHTSA Complaint #10501123 — 2003 BMW X5

OIL SEPARATOR FROZE CAUSING HIGH PRESSURE AND BLOWN SEALS. INITIAL COST ABOUT $1100 TO REPAIR. DEALER STATES THIS "HAPPENS ALL THE TIME" TO X5'S IN COLD WEATHER. TEMP WAS IN THE SINGLE DIGITS. IN JANUARY 2013 OIL SEPARATOR FROZE TWO MORE TIMES;HOWEVER, THIS TIME DAMAGING THE ENGINE - COST OVER $5000 TO REPAIR - BASICALLY TOTALING THE CAR. WITH ABOUT 15 MINUTES OF RESEARCH, THIS APPEARS TO BE A COMMON AND KNOWN ISSUE ON BMW X5 3.0, 4.4 AND 4.8 ENGINES FROM 2001 TO 2008... LOOKS LIKE THE PARTS WERE REDESIGNED IN 2009. LOOKS LIKE A SIMPLE PREVENTIVE MAINTENANCE ROUTINE AND INSULATED OIL LINES WOULD HAVE PREVENTED THE "CATASTROPHIC ENGINE FAILURE" AND DANGEROUS CONDITION OF TAILPIPE FIRE, OR BEING STRANDED IN ZERO DEGREE WEATHER (WHICH SEEMS TO BE A CONDITION REQUIRED FOR THE FAILURE). OWNER OF CAR IS THE ORIGINAL OWNER, WITH ALL MAINTENANCE BEING DONE AT LOCAL BMW DEALERSHIPS INCLUDING MAJOR SERVICES AT 60K AND 90K SO THERE APPEARS THERE IS NO "PREVENTIVE MAINTENANCE" INCLUDED IN EITHER OF THESE MAJOR SERVICE MILESTONES FOR THE KNOWN OIL SEPARATOR DEFECT. A RECALL ON THIS DEFECT TO INSTALL THE SMALL AMOUNT OF PARTS TO PREVENT "CATASTROPHIC ENGINES FAILURE" AND DANGEROUS CONDITIONS "BEING STRANDED IN SINGLE DIGIT WEATHER" SEEMS LIKE A LOGICAL CHOICE... OR AT LEAST CHANGING MAJOR SERVICE MILESTONES TO ADD PREVENTIVE MAINTENANCE SO THE PROBABILITY OF THE FAILURE CAN BE REDUCED. *TR
