Consumer Description

THIS PAST WEEK CONNECTICUT HIT A VERY COLD SPELL. 0*F. CRANK CASE VENT VALVE FROZE. AS A RESULT, TREMENDOUS PRESSURE BUILT INSIDE THE CRANK CASE, THE OIL CAP BLEW OFF AND THE ENGINE STOPPED WORKING PROPERLY. HAVE BEEN TOLD BY THE DEALER THAT THEY HAVE SEEN THIS PROBLEM BEFORE IN THE 2003 MODEL YEAR AND THAT IT IS NOT AN UNCOMMON PROBLEM IN VERY COLD WEATHER. WE HAVE ALSO LEARNT THE 2003 MODEL HAS A DESIGN FLAW WHERE THE VALVE IS NOT INSULATED AND NEWER MODELS HAVE CHANGED THE DESIGN TO CORRECT THE PROBLEM. PART REPLACED BY DEALER. WE WERE LUCKY OUR ENGINE DID NOT FAIL COMPLETELY. SINCE THIS PROBLEM IS KNOWN BY BMW, AND IS A CLEAR DESIGN DEFECT. SHOULDN'T IT BE THE SUBJECT OF A RECALL? *TR
