2004 BMW 530I WITH ONLY 54,000 MILES (6 YRS OF OWNERSHIP) - ON SUNDAY MORNING, MY ENGINE WON'T START ON 1/31/2010 ALL OF SUDDEN. - CALLED AAA FOR BATTERY CHECK AND JUMP START BUT IT WAS NOT A BATTERY ISSUE PER AAA. - TOWED MY CAR TO MY BMW DEALER FOR CHECK UP - BMW DEALER CHECKED AND TOLD ME MY ENGINE IS DEAD AND NEED TO REPLACE IT WITH A NEW ENGINE. IT WOULD COST $13,000 (THIS IS RIDICULOUS.) - I TOLD THEM IT MUST BE ENGINE DEFECT AND CHECK THIS FOR ME AND TELL BMW HQ - MY DEALER CHECKED MY MAINTENANCE RECORD WITH THEM AND THEY ARE TRYING HELP AND FIND OUT WHAT WAS THE ISSUE WITH THE ENGINE. THEY DON'T UNDERSTAND EITHER. - DEALER IS STILL TRYING TO FIND OUT WHY MY ENGINE DIED WITH A GOOD MAINTENANCE RECORD AND ONLY 54,000 MILES (NO FLOOD INVOLVED)...
