NHTSA Complaint #717162 — 1994 BMW 530I

BMW WAS AWARE OF A PROBLEM WHERE SULPHER FROM US FUELS WAS CAUSING THE CYLINDER WALLS OF THE M60 V8 MOTOR TO DETERIORATE. APPARENTLY THEY USED A NEW METAL CALLED NIKASIL (ALUMINUM IMPREGNATED WITH NICKEL AND SILICONE). ONCE THE CYLINDER WALLS BECOME DAMAGED, THE PISTON RINGS CAN NO LONGER SEAL PROPERLY, CAUSING "LEAKDOWN" OR AIR TO ESCAPE PAST THE PISTON AS IT ATTEMPTS TO COMPRESS AIR INTO THE COMBUSTION CHAMBER. ALTHOUGH BMW KNEW OF THE DEFECT, THERE WAS NO RECALL ISSUED. THROUGH REASEARCH, AND TALKS WITH BMW MECHANICS, I FOUND THAT BMW HAS REPLACED THOUSANDS OF THE EFFECTED MOTORS. BMW EVEN EXTENDED THE WARRANTY PERIOD ON THE ENGINE TO 100K MILES. I OWN A BMW 530I WITH THE 3.0 LITRE M60 NIKASIL MOTOR. IT BEGAN HAVING PROBLEMS AT AROUND 96K MILES. I NOW HAVE 109K MILES. THE CAR RAN FINE, BUT HAD A ROUGH IDLE. APPARENTLY THIS IS A SYPTOM OF THE "LEAKDOWN" PROBLEM. I BROUGHT THE CAR TO GIRARD BMW TO HAVE IT TESTED. THEY CONFIRMED THE ENGINE HAD THE PROBLEM ASSOCIATED WITH THE DEFECTIVE ENGINE BLOCK. HOWEVER, WHEN I GOT MY CAR BACK, IT RAN VERY POORLY. BEFORE LEAVING THE DEALER, I TOLD THEM THAT IT WAS RUNNING WORST THEN WHEN I BROUGHT IT TO THEM. THEY INDICATED IT WAS DUE TO THE ENGINE BLOCK PROBLEM. I INFORMED THEM I WAS CONCERNED TAKING THE CAR FOR FEAR I WOULD GET STUCK SOMEWHERE. THEY ASSURED ME I WOULD NOT. TWO DAYS LATER, MY CAR WOULD NOT START. GIRARD HAD A TOW TRUCK PICK UP MY CAR. I HAVE RECEIPTS FROM A LOCAL GARAGE SHOWING THAT THE CAR WAS EXPERIENCING THE PROBLEM WHILE IT WAS STILL COVERED UNDER WARRANTY. AT THE TIME, I WAS UNAWARE THAT BMW HAD EXTENDED THE WARRANTY, OR THAT THERE WAS ANY KNOWN PROBLEMS WITH THE MOTOR, AS I RECEIVED NOTHING FROM BMW INDICATING SUCH. I DID RECEIVE OTHER RECALL INFORMATION ON THE CAR HOWEVER NOTHING REGARDING POTENTIAL ENGINE PROBLEMS. MY CAR IS NOW BARELY OVER THE WARRANTY PERIOD (9K MILES) AND BMW WILL NOT FIX IT. *AK
