I DID A QUICK SEARCH OF THE NHTSA DATABASE AND HAVE FOUND APPROX. 60 COMPLAINTS ABOUT THIS EXACT SAFETY ISSUE. I'M QUITE SURPRISED THAT THE NHTSA HAS NOT SANCTIONED BMW ABOUT THIS PROBLEM. AFTER BEING INFORMED THAT THIS IS A COMMON SAFETY PROBLEM WITH THESE CARS AND BEING ADVISED TO CHECK FOR IT, I FOUND THAT THE SPOT WELDS HOLDING THE DIFFERENTIAL MOUNT TO THE SUB-FRAME HAD TORN LOOSE, AND THE SUB-FRAME AND MOUNT WERE BOTH BEGINNING TO TEAR. HAD I NOT FOUND THE PROBLEM IN TIME, THE DIFFERENTIAL WOULD HAVE SEPARATED COMPLETELY FROM THE CAR (AS HAS HAPPENED TO OTHERS).

MY 1998 BMW M ROADSTER, WITH UNDER 71,000 MILES, IS SHOWING SIGNS OF REAR SUBFRAME FAILURE. I AM AWARE THAT THIS HAS HAPPENED ON MANY OF THEM THAT WERE DRIVEN HARD ON TRACKS, BUT THIS CAR HAS BEEN USED ALMOST EXCLUSIVELY FOR DRIVING ON THE HIGHWAY TO/FROM WORK AND BETWEEN CHATTANOOGA AND ATLANTA. AFTER RECENTLY HEARING SOME MORE RATTLING FROM THE REAR, I'VE LIFTED THE TRUNK MAT AND FOUND THE TELL-TALE SIGN: POPPING SPOT-WELDS. I'M NOT SURE HOW SEVERE IT IS AT THIS POINT, AND AS A STUDENT, I CAN'T AFFORD TO TAKE IT TO A DEALERSHIP OR OTHER SHOP TO HAVE IT CHECKED YET, BUT IT WILL BECOME A SEVERE PROBLEM, AND I HAVE HEARD THAT BMW IS UNLIKELY TO OFFER ANY ASSISTANCE. I WOULD LIKE ANY ADVICE YOU CAN OFFER. *TR

I HAVE A 1998 BMW M ROADSTER. THE SUBFRAME IS STARTING TO RUPTURE (TEAR) AND WELDS IN THE TRUNK ARE BREAKING. IF THIS CONTINUES THE RESULT COULD CAUSE AN ACCIDENT. THE PROBLEM WAS JUST DIAGNOSED SO NO REPAIR ACTION HAS BEEN TAKEN. *NM

I READ ABOUT THE REAR SUBFRAME TEARING OFF OF BMW Z3S AND M ROADSTERS AND DECIDED TO HAVE A LOOK AT MINE. FOUND THE WELDS HOLDING THE SUBFRAME ON WERE FAILING BADLY AND THE BRACKET HOLD MY REAR DIFFERENTIAL WAS SPLITTING. THIS IS A VERY COMMON PROBLEM I GUESS. *NM

FORTUNATELY, I SPOTTED IT WHILE REPLACING THE EXHAUST AND NO ONE WAS HURT. I AM A PHD MATERIALS SCIENTIST AND SPOT THIS AS METAL FATIGUE. *NM
