Engine Knocking Noise Problems of BMW X5

I'm writing to you regarding my 2012 BMW X5m. On October 8, 2017 I was driving my car and suddenly the check engine light came up and almost immediately the car lost power and a very loud banging noise start coming up from the front of the car. I was in the middle of a busy intersection when this happened and the car could barely move. I pulled over as soon as I was out of the intersection and got the car towed to the nearest BMW authorize dealer - BMW of silver spring, MD (3211 automobile blvd, silver spring, MD 20904). After a few conversations with the dealer I was told that I have to replace the entire engine and that there will be no effort made to determine the reason for the engine failure. The car is a well maintained vehicle and I have records for all the maintenance work done. That includes oil changes done every 5,000- 7,000 miles. I told the dealer that I suspect the issue could be a faulty fuel injector. The symptoms I shared with the BMW dealer were rough starts, rough idle and fuel smell were present especially the day we towed the car in. The dealer refused to accept any of the shared information and denied my request for the fuel injectors to be checked although they are under extended warranty. As a result, I was given no choice but pay the cost of the entire engine replacement. The dealer refused to give me the old engine back because I wanted it inspected to check whether a faulty injector was the reason for the engine failure.
