1999 BMW Z3 Structurebody Problems

VERY WELL KNOWN FAILURE, JUST SEARCH FOR "BMW Z3 SUBFRAME FAILURE". IT IS A DESIGN FLAW BY BMW THAT AFFECTS A LOT OF Z3'S THROUGH ALL MODEL YEARS. MINE STARTED TO POP ONE WELD AT 88K MILES. IT CAN CAUSE THE REAR ALIGNMENT TO BE OFF, IN WORST CASE THE TRUNK FLOOR IS TORN OUT AND THE DIFFERENTIAL FALLS TO THE GROUND. CLUNKING FROM THE BACK WHILE SHIFTING IN THE FIRST TWO GEARS IS ONE INDICATOR THIS DAMAGE IS NOT FAR AWAY. THIS IS ONE FORUM THREAD THAT DESCRIBES THE ISSUE WELL: HTTPS://WWW.BIMMERFORUMS.COM/FORUM/SHOWTHREAD.PHP?1979601-SUBFRAME-TRUNK-FLOOR-DIFFERENTIAL-MOUNT-FAILURE

1999 Z3 M COUPE DIFFERENTIAL MOUNT TRUNK FLOOR SUPPORT FAILURE. I TOOK IN MY CAR FOR MY 90 THOUSAND MILE SERVICE AND WAS INFORMED BY THE SHOP (WWW.THEMSHOP.COM) LOCATED IN GLENDALE, CA. THAT MY SUBFLOOR WAS CRACKED AND UNLESS I FIXED IT MY CAR WOULD BE USELESS, AND NOT DRIVABLE. I HAD TO SPEND OVER $2,800 TO FIX MY CAR WHICH IS VERY DISAPPOINTING ESPECIALLY SINCE THIS IS A WEEKEND CAR NOW AND WHEN YOU PAY $46,000 FOR A BMW YOU DO NOT EXPECT THE FRAME TO FAIL.... *TR

ALSO THE SINGLE REAR DIFFERENTIAL MOUNT ALSO HAS A TEAR INTHE METAL THAT EEQUALS TO ONE AND HALF INCH ON THE MOUNT CONSISTING THAT 33% OF THE MOUNT HAS FAILED AND IS GETTING WORSE. ALSO THE TEARING FROTHE INTERIOR IS ALL THE WAS THOUGH THE CAR ALLOWING EXAUST FUMES INTO THE CABIN OF THE CAR. *AK
