I BROUGHT MY CAR INTO THE DEALERSHIP BECAUSE IT STALLED AND THE CHECK ENGINE LIGHT CAME ON BRIEFLY AND SHUT OFF. THE CAR WAS ALSO HESITATING ON ACCELERATION. THE DEALER DETERMINED THE CAUSE WAS A NEEDED THERMOSTAT REPLACEMENT. HOWEVER, ONCE UNDER THE CAR, THE TECHNICIAN NOTED 3 OF 4 ENGINE MOUNT BOLTS WERE "BROKEN" AND NEEDED TO BE REPLACED. HE SAID IT WAS CONSIDERED "WEAR AND TEAR" AND WAS NOT COVERED UNDER WARRANTY EVEN THOUGH ONLY ONE BOLT WAS NOW HOLDING THE ENGINE FROM FALLING OUT. THIS REPAIR WOULD COST APPROXIMATELY $400. UPON INVESTIGATION, I NOTICED THIS WEBSITE: HTTP://WWW.BIMMERFEST.COM/FORUMS/SHOWTHREAD.PHP?T=528870 WHERE PEOPLE POST ABOUT THEIR BMWS. IT SEEMS THAT SEVERAL OTHERS HAVE HAD THIS SERIOUS PROBLEM AROUND THE SAME MILEAGE POINT WITH THE SAME MAKE AND MODEL, AND SEVERAL COMPLAINED THAT THE REPAIR WAS NOT COVERED UNDER WARRANTY, EVEN THOUGH IT APPEARS TO BE A MANUFACTURING DEFECT AS THE BOLTS ARE MADE OF ALUMINUM, NOT A STRONG MATERIAL, AND ONE THAT EASILY BREAKS. *TR
