NHTSA Complaint #766914 — 1993 BMW 325I

THE SUBFRAME CRACKED UNDER NORMAL DRIVING CONDITION. THE CRACK IS LOCATED ON THE SUBFRAME WHERE THE REAR CONTROL ARM ATTACHED. I M AFRIAD THAT THE REAR AXLE MAY FALL OFF THE VEHICLE DURING DRIVING. I HAVE FOUND OTHER OWNER COMPLAINT ABOUT THIS ON THE E36 DESIGN. THIS IS A WEAKNES ON THE SURFRAME THAT CASUES IT TO FAIL IN FATIGUE. I AM A METALLURGICAL ENGINEER AND HAVE VISUALLY INSPECTED THE CRACK. IT DID NOT SHOWN ANY CORROSION, THUS INDICIATING THAT IT IS NOT A ENVIRONMENTAL INDUCE FAILURE. THIS PROBLREM IS A MANUFACTURE PROBLEM IN AN INADEQUATELY DESGINED COMPONENT. A SUBFRAME IS A STRUCTURE COMPONENT AND SHOULD FAIL UDER NORMAL OPERATING CONDITIONS.THE ESTIMATE TO FIX THIS PROBLEM IS OVER $4000.00. IHAVE CONTACTED BMW CUSTOMER RELATION, THE REPRESENTATIVE HAS DENIED THE PROBLEM AND REFUSED TO LET ME TALL TO HER SUPERVISOR. I BELIEVE THIS IS SAFETY RELATED ISSUE AND HOPE THAT NHTSA CAN ASSIST THE CAR OWNERS TO RESOLVE THIS ISSUE.*AK
