I just dropped off my 2014 MS60 with 63k miles for the infamous milling sound to the SC in Littleton, CO. They immediately diagnosed it as the drive unit. I received notification tonight the car would be ready for pickup tomorrow. What I wasn’t expecting was the amount due on the invoice. It says I am being charged ~$5800 for a drive unit replacement. Unless I am missing something, wouldn’t this be covered under warranty? Only other thing I can think of is that I am not the original owner. I bought it via private sale. If anyone can shed any light on this I’d really appreciate it.
