2013 BMW 550XI Engine Problems

I WAS DRIVING MY BMW 550 XI ON THE HIGHWAY AT 70 MPH WHEN I HAD WHAT WAS TERMED BY THE BMW SERVICE TECHNICIAN AS A "CATASTROPHIC ENGINE FAILURE". AS I WAS DRIVING DOWN THE HIGHWAY AT I SUDDENLY LOST ALL POWER TO THE DRIVE TRAIN. I IMMEDIATELY HAD TO TAKE EVASIVE ACTION TO AVOID AN ACCIDENT AS ON A BUSY HIGHWAY IN CHICAGO AND SUDDEN LOSS OF POWER IS DANGEROUS. I WAS ABLE TO GET STOPPED AT THE SIDE OF THE ROAD AND WAS UNABLE TO RESTART THE ENGINE. I THEN HAD THE VEHICLE TOWED TO BMW OF ORLAND PARK WHERE THE SERVICE TECHNICIAN DISMANTLED MY ENGINE TO DETERMINE THE CAUSE OF THE ENGINE FAILURE. THE DETERMINATION WAS MADE THAT INDEED THE ENGINE HAD A "ROD BEARING FAILURE" WHICH CAUSED THE CATASTROPHIC FAILURE. AS I UNDERSTAND ENGINES VERY WELL IT IS NOT SURPRISING THAT AN ROD BEARING COULD FAIL....

TL* THE CONTACT OWNS A 2013 BMW 550XI. WHILE DRIVING AT ANY SPEED, THE VEHICLE EMITTED SMOKE FROM THE EXHAUST PIPE WITHOUT WARNING. THE FAILURE RECURRED. THE VEHICLE WAS TAKEN TO THE BMW OF ROANOKE DEALER (2824 FRANKLIN RD SW, ROANOKE, VA 24014, 540-274-2475) WHERE IT WAS DIAGNOSED THAT THE VALVE STEM SEAL IN THE ENGINE NEEDED TO BE REPLACED. THE TECHNICIAN ALSO STATED THAT THE OCCURRENCE WAS A KNOWN FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT THE WARRANTY WAS EXPIRED. THE FAILURE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 115,000. THE VIN WAS NOT PROVIDED.
