They kept the vehicle over the weekend and found that a technical bulletin came down for my vehicle which required the rebuild of my HVAC system for my new engine. They ordered the parts, set me up with a courtesy car and even took care of the oil change at no cost (engine is still under warranty from when they blew it so that took care of the parts and labor for the HVAC rebuild).

So all is well!
