2000 BMW M Roadster problems

“SUB FRAME HAS CRACKED UNDER NORMAL DRIVING.DURING REGULAR COMMUTES AND DRIVES ON RESIDENTAL ROADS I BEGAN TO HEAR NOISES FROM THE REAR OF THE CAR AND I TOOK A LOOK UNDERNEATH CAR, THERE WAS A SMALL CRACK IN THE DIFFERENTIAL MOUNTING EAR. I ALSO CHECKED INSIDE OF THE HATCH AREA AND REMOVED THE SOUND DEADENING REVEALING A SMALL SEPARATION OF THE TRUNK FLOOR PANEL ON THE PASSENGER'S SIDE.”

“MY ULTIMATE DRIVING MACHINE IS SPLITTING FROM THE SEEMS!!! I HAVE A 2000 BMW M ROADSTER (Z3) AND RECENTLY I NOTICE A CREAKING IN THE REAR. THEN ONE DAY ON MY WAY TO WORK I HEARD WHAT SOUNDED LIKE A TEAR. IT TURNS OUT THAT THE REAR DIFFERENTIAL MOUNT HAD SEPARATED FROM THE SHEET METAL UNI-BODY CONSTRUCTION. THE CARS DIFFERENTIAL HOUSING WAS PRACTICALLY DRAGGING ON THE GROUND. THE ONLY THING HOLDING IT TO THE CAR WERE THE SHOCKS AND SPRINGS. THE TRUCK FLOOR THAT THE MOUNT WAS SPOT WELDED TO HAS SEPARATED FROM THE CAR. THIS IS A MAJOR DESIGN FLAW! THE CAR AT THIS MOMENT IS NOT DRIVABLE! MY CAR IS NOW AT A DINAN SHOP. DINAN IS A COMPANY THAT MAKES HIGH PERFORMANCE PARTS FOR BMW'S. WHEN DINAN PARTS ARE USED AND INSTALLED AT AN AUTHORIZED DINAN DEALER A BMW WOULD STILL BE ENTIRELY WARRANTED BY BMW.

IT COSTS $299 HOWEVER REQUIRES 16 HOURS OF WORK BY A HIGHLY SKILLED TECHNICIAN WITH FABRICATION AND WELDING SKILLS. I SEE THIS HAS A POTENTIALLY LIFE THREATENING SCENARIO IF THIS WOULD HAVE HAPPENED ON A MAJOR HIGHWAY. I…”

THE RE-ENFORCEMENT KITS ARE SOLD BY FURTHER CONFIRMING THAT THIS IS A MANUFACTURING PROBLEM. DROPPING YOUR DIFFERENTIAL WHILE DRIVING COULD CAUSE AN ACCIDENT. *TT”

“THE AIRBAG (SAFETY RESTRAINT SYSTEM) LIGHT ON MY CAR'S DASH INSTRUMENT PANEL KEEPS COMING ON. INFORMATION ON THE Z-3 ROADSTER INTERNET MESSAGE BOARD (HTTP://BIMMER.ROADFLY.ORG/BMW/FORUMS/Z3/) INDICATES THAT THIS PROBLEM IS A COMMON FAULT ON THE BMW Z-3/M ROADSTER MODELS, DUE TO FAULTY ELECTRICAL CONNECTORS UNDER THE SEAT OR FAULTY SENSORS IN THE SEAT BELT LATCHES. SINCE THIS COMMON FAULT AFFECTS THE SAFETY RESTRAINT SYSTEM, BMW SHOULD BE REQUIRED TO ISSUE A RECALL TO FIX THESE PROBLEMS.*AK”
