“My last interaction with a service department came when I requested a complete once over as I was taking a very long road trip and the car came back perfectly fine accoridng to them. Not even 2300 miles later, less than an oil change, I had a catostrophic failure that lead to an almost $600 repair out of pocket.”

SUE? Really? People toss that word around a lot. Surely you mean have the part warrantied.
