16 complaints

WHITE STEAM WAS COMING FROM UNDER THE HOOD ONTO THE FRONT WINDSHIELD. THE STEAM WAS FOGGING THE WINDSHIELD, AND CAUSING POOR VISIBILITY WHILE DRIVING 50-55 MPH. CONSUMER WAS ABLE TO GET THE VEHICLE TO A REPAIR SHOP. DEALER INFORMED THE CONSUMER THAT THE UPPER NECK CONNECTOR OF THE RADIATOR HOSE BROKE.*AK

2ND CATASTROPHIC RADIATOR FAILURE. NOT A LEAK, THE NECK BREAKS OFF CAUSING IMMEDIATE LOSS OF COOLING. 1ST RADIATOR AT 45K, 2ND AT 92K. BASED ON OTHER'S EXPERIENCES, THIS IS VERY COMMON FOR THIS MODEL (AND EVEN LONGER LIFE THAN MANY). CAUSES LOSS OF VISION DUE TO AMOUNT OF STEAM RELEASED. LESS EXPERIENCED DRIVER MAY HAVE DIFFICULTY CONTROLLING VEHICLE TO GET TO SIDE OF ROAD QUICKLY TO SHUT DOWN. NO WAY TO PREDICT THE FAILURE. SAME ISSUE WITH EXPANSION TANK. BOTH FAILURES ARE ON PLASTIC PARTS.*AK

I WAS DRIVING DOWN A BUSY STREET ONE EVENING AND AS I CAME TO A LIGHT, SMOKE STARTED COMING OUT OF MY HOOD. FORTUNATELY IT WAS IN THE EVENING AND TRAFFIC WAS LIGHTER THAN USUAL. I PULLED INTO A PARKING LOT OFF THE SIDE OF THE ROAD. HAVING KNOWN OTHERS THAT THIS HAS HAPPENED TO, I FIRST CHECKED THE RADIATOR AND SURE ENOUGH, THERE WAS A LARGE CRACK DOWN THE SIDE OF THE HOUSING. I HAD THE CAR TOWED HOME AND PURCHASED A NEW RADIATOR FROM BMW OF SEATTLE THE FOLLOWING MORNING. THE NEW RADIATOR WAS ABOUT $200, A FEW HOURS OF MY OWN LABOR AND A FEW MORE HOURS DETAILING THE ENGINE PAY AND HEADLIGHTS WHICH HAD RADIATOR FLUID ALL OVER THEM. ALSO FROM THE EXPERIENCE OF OTHERS WHO OWN E39 BMW 540S, I FULLY EXPECT THIS TO HAPPEN AGAIN IN THE NEXT 50K MILES. I ALSO EXPECT THE EXPANSION TANK TO GO WITHIN THE NEXT FEW MONTHS. *AK

MULTIPLE COOLANT DEFECTS ON THE 1998 540. THE CAR HAS NOW HAD 3 RADIATORS, 3 THERMASTATS, WATER TUBE SEALS REPLACED TWICE, AND A WATER PUMP. THE COSTS HAVE BEEN OVER $3,500. THESE LEAKS ARE NOT JUST EXPENSIVE, THEY POSE A REAL DANGER TO CAUSING PERSONAL INJURY AND DAMAGE. THE FAILURE RATE IS KNOWN TO BE VERY HIGH.

While stopped (engine still running) at a gas station, the driver side airbag and driver side side curtain airbag both went off. The battery disconnect feature was also triggered. Very lucky I wasn't driving when this occurred.

POWER TRAIN

1 complaint

I HAVE DRIVE STANDARD TRANSMISSIONS FOR OVER 40 YEARS, I HAVE NEVER HAD A CLUTCH PROBLEM UNTIL A PURCHASED A '95 540I (KNOW FOR POORLY DESIGNED CLUTCHES, PARTICULARLY THE PRESSURE PLATE). I BOUGHT THIS NEW '98 WITH HOPES THE PROBLEM WAS SOLVED, NO SUCH LUCK. IF I HAD THE FAILURE ON A MAJOR HIGHWAY OR CROWDED ROAD I EASILY COULD HAVE BEEN IN AN ACCIDENT THE TIME FOR THE CLUTCH TO STOP WORKING ENTIRELY WAS VERY SHORT.
