If you have the leaks that are shown in post #12, I wouldn't panic too much. I'd try cleaning it up with brake clean on a rag, and seeing if it comes back. My car had that, and it hasn't come back. I'm wondering if they used oil or something to lube the seals, and excess lube flung out and dripped down. If you have drips or puddles though, that's a different story.. I guess I'm also coming from a place of not wanting toyota to do any invasive repairs that they don't have to do.
