What kind a warranty? Do you have an option to extend it?

Personally, I would speak directly with the foreman and firmly but politely let him know that you're asking for his help and expect him to take care of your situation. Ask him if he's able to do that... yes or no. If not, go above his head and, if necessary, raise a polite furry.

The bottom line is something failed, that something is covered by the warranty you purchased, and it's on the company underwriting that warranty, Mercedes Benz USA, to live up to their end of the warranty contract. If some dealership is getting in the way of that, you have a major issue with MBUSA.

Good luck.
