NHTSA Complaint #10680661 — 2002 BMW X5

I REPLACED THE OIL SEPARATOR AT BMW DEALERSHIP 1/10/08 BECAUSE OIL WAS BECOMING POLLUTED WITH WATER EVEN AFTER I EXPLAINED TO DEALERSHIP PREVIOUS TIMES THE OIL LOOKED MILKY WHEN I DID A DIPSTICK CHECK. THE DEALER TOLD ME THE PART FAILED BEFORE IT CAUSED EXTENSIVE DAMAGE AND A CONDITION KNOWN AS HYDROLOCK, WHICH COULD CAUSE ENGINE TO SEIZE. LAST WEEK IN VERY COLD WEATHER CONDITIONS,1/13,2015 MY CARS CABIN FILLED WITH BLACK SMOKE. I PULLED OVER AND FOUND THE ENGINE SPOILED WITH SMOKING OIL, I TOOK IT TO AN INDEPENDENT REPAIR SHOP AND IT WAS THE OIL SEPARATOR AGAIN. THE PART IS ALSO KNOWN AS THE CRANKCASE VENT VALVE I HAD IT CHANGED/REPAIRED, IT IS EXPENSIVE AND CAN CAUSE SERIOUS VEHICLE DAMAGE AND ACCIDENTS. I THINK FOR THIS TO HAPPEN TWICE POINTS TO A DANGEROUS VULNERABLE PART. THIS TIME MY CAR COULD HAVE EASILY CAUGHT ON FIRE, THANKFULLY I WAS CLOSE TO THE REPAIR SHOP.INCIDENTLY THEY HAD THREE BMW'S ASIDE FROM MINE WITH THE SAME PROBLEM. ALSO THE TWO SEPARATE INCIDENTS WERE REPAIRED WITH COLD WEATHER/INSULATED KITS. I COULD NOT EVEN OPEN MY DRIVERS SIDE DOOR WINDOW TO GET AIR IT WAS INOPERABLE WHEN THE CABIN FILLED WITH SMOKE WHICH WAS ALMOST INSTANTANEOUS. *TR
