I am still in the process. Just talked with insurance today and they agreed to OEM glass and trim, but some underlying corrosion and previous installer (hack) drill holes in the body will not be covered.
If your windshield leaks now, I'd check with the shop that installed it (unless it was prior to your ownership).
I'm learning first hand that who installs your windshield matters an awful lot in these cars. I would flat out refuse any repair that involves any kind of screw. Even if that means paying to trailer the car to a new shop. It's hard to screw it up using the correct rivets. It's nearly impossible to do it "right" in a way that isn't going to rot the A-pillar if screws are used. There's a reason the Toyota/Lexus design doesn't use any screws - unfortunately most installers will just use screws as provided in some aftermarket install kits.
Abra Auto glass has it in their system to use factory parts. I had them fight for me and State Farm paid it. There are Colorado locations. Mine came out perfect.
