I had mine replaced as well.
The dash and windshield come out. My dealer ordered a new windshield as precaution after removing it instead of reapplying the same one. NO issues to date from the repair **knock on wood**
Not happy it happened. And not happy of the extensive repair process. Once the part came in it was a 2 1/2 day process. They did tear down on afternoon and then the repair and began reinstalling everything. Finished the 3rd morning and had a new windshield put in and out the door I went (with that smell lurking for some time ...)
