2006 BMW 7 SERIES Engine And Engine Coolingengine Problems

BMW OF NASHVILLE IS TELLING ME I NEED A NEW MOTOR IN MY 2006 750I BMW; THE ENGINE ONLY HAS 59,000 MILES ON IT. THEY SAY THE ENGINE BLOCK IS BAD. I AM 9,000 MILES OUT OF WARRANTY SO THEY ARE SAYING IS ALL ON ME. I HAVE HAD ALL SERVICES REQUIRED AND NOT ONCE WAS IT BROUGHT TO MY ATTENTION THAT MY ENGINE WAS GOING BAD AND NOW IT'S GONE FROM BEING GOOD TO NEEDING ANOTHER ENGINE? DUE TO THE MILEAGE I HAVE ON THE ENGINE AND I FIND THIS TO BE A DEFECTED ENGINE AND WOULD ASK FOR ASSISTANCE IN THIS MATTER. *TR
