LEMONPILOT,
It's pretty rare for a new Honda to leak oil...small consolation I know. It doesn't sound like the stealership was able to ascertain where the leak is coming from. You might want to get a can of brake and part cleaner and get underneath the thing yourself. Clean up everything you can and then drive for a short distance. Hopefully, you'll be able to pinpoint the location of the leak and give the parts-swappers at Honda something to go on.
