I've been to Tyson's Ford a few times. Had some problems 2-3 years ago getting some warranty work done (first the fuel filler neck, then a set of brake rotors). Went there again fairly recently for a bad wheel bearing and they were much better, like a different shop. Probably due to the fact that my car is now out of warranty and I paid out of pocket.
It does seem strange that it would take 2700 miles for the oil to leak out, and I don't even know how it would be possible to install the oil filter incorrectly... unless it was too loose or something.
