Hi. GM does have a service bulletin on having a water leak from the windshield that drips onto the fuse panel. And does cause various electrical issues. This service bulletin is covered under the GM bumper to bumper warranty. Do you still have bumper to bumper warranty?
it is possible that there was a water leak from somewhere else. I can not speak for what the dealer did. Or didnt do. But there is a known concern with the windshield leaking causing the fuse box to need to be replaced. The same bulletin has the mechanic check for leaks from the sunroof drain as well (if equipped). You can ask the dealer why the windshield was not replaced in the first place. Maybe they can offer some assistance with the cost of the repair for you.
