Not all dealerships have a great service department....
I took my work truck into a Ford dealer in Renton because it was having some issues starting They kept it for two days and did a 2000 dollar fix. Oddly enough the next morning (the first time I started it cold it did the same thing it had been doing before. Called my trusty service advisor pissed and he told me something else must have gone wrong in my ten minute drive home that displayed the same symptoms.

After driving the thing back down there and having a few choice words with him they took it back and found some more stuff to do to it that sort of helped but never actually solved it.
When I moved I mentioned it to my new service advisor at the enumclaw dealer and they fixed it overnight with an oil change and never had an issue with it after that.
