I bought my '13 FR-S from a dealership five hours and one state away simply because it was about $1500 less than anything I could find locally; one of their used, "Certified" cars. When I took it to my local dealership the first time for service (and after having the window-freezing issue), they intially denied knowledge of any TSB. Being the somewhat compulsive person I am, I furnished them with the TSB number and a printout. They have been great ever since. I am very nice, even when slight disagreements may arise, and so are all of their service folks up and down the entire chain.
Perhaps just showing them the TSB? Toyota dealerships still service Scions.. should NOT be an issue in the slightest.
