2000 BMW E46 Engine And Engine Coolingcooling System Problems

SINCE PURCHASE OF THIS VEHICLE (2000 BMW 323I, VIN [XXX]), WE'VE HAD NOTHING BUT TROUBLE WITH IT AND NO ONE CAN FIX IT PROPERLY. IT'S LEFT MY WIFE AND CHILDREN STRANDED BECAUSE OF A KNOWN VANOS TIMING PROBLEM. AND NOW I'VE HAD TO HAVE THE ENGINE COMPLETELY REPLACED AT THE COST OF $7,300 BECAUSE OF ANOTHER KNOWN PROBLEM...THE CHEAP, PLASTIC COOLANT EXPANSION TANK THAT CRACKED AND CAUSED THE ENGINE TO OVERHEAT TO COMPLETE FAILURE. THESE ARE A FEW OF THE KNOWN PROBLEM THAT BMW IS KEENLY AWARE OF. WHEN WILL SOMEONE HOLD THEM ACCOUNTABLE FOR THE PRODUCTION OF VEHICLES MADE WITH INFERIOR COMPONENTS AND MAKE THEM RECALL THESE SUSPECTED PARTS? I KNEW I SHOULD HAVE BOUGHT A TOYOTA! *NM UPDATED 07/11/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
