2011 BMW 535i engine goes at 84,000 miles
 I purchased my 2011 BMW 535i new from the dealer with only 495 miles.  Service has always been timely and performed only by BMW dealer.  Recently the car started making a rattling noise intermittently when accelerating and decelerating so I took the car into the dealer.  I was informed that the engine had metal in it and needed to be replaced at a cost of $31,000.  BMW is refusing to replace the engine and is only willing to cover 20% of the cost.  Metal in the engine is not something that I could have caused.  The engine is either defected, or the service that I thought was being performed on my car for the last 6 years has not been performed by the dealer, or if done perhaps  incorrectly.  I'll never buy another BMW after this experience.  BMW obviously does not stand behind its produce.  So much for the "ultimate driving machine".
