Electrical system
5 reports
“Component or System Failed: The critical safety component that failed—and was deliberately tampered with—is the ABS/DSC (Anti-lock Braking System / Dynamic Stability Control) module. The compromised component is currently on the vehicle and is readily available for physical inspection upon request. How Safety Was Put at Risk: My safety and the safety of the public were severely compromised because the selling dealership actively concealed a total failure of the primary braking and traction control systems. The ABS/DSC module was physically severed and glued back together to hide the defect. This deceptive tampering disabled critical emergency braking and stability functions without my knowledge, creating an extreme accident hazard during adverse driving conditions. Confirmation by Dealer or Service Center: Yes, the pre-existing defect was confirmed by a franchise dealership service center prior to my purchase on 5/23. Official service records document that at 55,106 miles, the vehicle was diagnosed with an active ABS/Traction failure and a tampered "customer supplied part" was noted on the DSC unit. Furthermore, the selling dealership's own internal documents…”

“THIS DEFECT WAS NOT CAUSED BY AN ACCIDENT, HOWEVER THE POTENTIAL DANGER TO THE PASSENGERS IN THE VEHICLE IS AN OPEN QUESTION. THE DRIVER'S SEAT IN MY 2001 Z3 ROCKS BACK AND FORTH WHEN ACCELLERATING, COMING TO A STOP OR EVEN WHEN MERELY SHIFTING MY WEIGHT ON MY RIGHT LEG WHEN MOVING MY RIGHT FOOT FROM ACCELLERATOR TO BRAKE. I HAVE NOTIFIED BOTH MY DEALER, BMW CLEVELAND, AND BMW NORTH AMERICA OF THE PROBLEM. THE DEALER INITIALLY DENIED THAT A PROBLEM EXISTED THEN, AFTER GETTING BMW NORTH AMERICA'S CUSTOMER SERVICE INVOLVED, ADMITTED THE PROBLEM AND ATTEMPTED TO FIX THE PROBLEM. HOWEVER, BY OCTOBER OF 2002 THE PROBLEM HAS RETURNED. THE DEALER HAS NOW UPON A LATER VISIT STATED NOTHING CAN BE DONE. I AM ONCE AGAIN IN CONTACT WITH BMW NORTH AMERICA WHO DENIES THAT I HAVE A PROBLEM AND DENIES BEING AWARE THAT THIS PROBLEM IS A PERVASIVE DESIGN DEFECT AMONG Z3'S. I HAVE LOCATED AND FORWARDED TO BMW NORTH AMERICA DOCUMENTATION THAT LOOSE SEATS ARE IN FACT A PERVASIVE PROBLEM AMONG Z3'S. THAT COUNTLESS OWNERS HAVE REPORTED THIS PROBLEM TO THEIR DEALERS AND THAT OTHER OWNERS HAVE COMMUNICATED THE EXISTENCE OF THIS PROBLEM TO BMW NORTH AMERICA REPRESENTATIVES. I HAVE ALSO…”
