I think the 2016s have a 5 year 60,000 mile power train warranty. You are just slightly over on miles. The fact that some ******* said it’s perfectly acceptable for the motor to suffer catastrophic failure at that mileage is pure *********. You will be out atleast 5,000.00. The dealer will nail U for labor, every nut bolt, seal, all fluids. I would consider taking it to another shop and have them find out what failed. They can probably do that by pulling the timing chain cover and oil pan. If it were moving parts you would have heard it destroy itself. It’s not going to silently go while driving....
