Toyota - Prius :: 2010 - Crack Windshield Leaking

Had an enormous crack in the windshield of our 2010 Prius and recently had it fixed. It leaked. Tech came out to fix the problem and check for water damage-we didn't see any at the time, but the fix didn't take and it's leaking again. This time, much worse. Here's what the discussion title refers to.

I'm concerned that the water damage will contribute to a problem down the road- corrosion in the electronics in the roof, damage to the carpeting(?) on the ceiling, mold etc. I would like to take the car into the dealer and have them give it a once-over, but want the glass repair shop to foot the bill. My philosophy is: I wouldn't have to get things checked out if you hadn't botched the install-twice. Their philosophy is: unless you can show us evidence of malfunction, we're not paying for someone else to look at it. I feel like they should go the extra step to put my mind at ease and make sure that any developing problem can be addressed now instead of having to wait until something goes bad.
