I had the same issue on my 2016 Wildcat 295rsx. In a very heavy rain storm, a small amount (collected about 6-8 ounces over 8 hours) dripped thru the return air vent that's located in the ceiling (if you're facing the bedroom headboard, it's above you to the right).
I was going to take it in for warranty and called the dealer's service dept to get an appointment. The person that took my call was actually a service tech. She said they see that particular drip many times on front mounted A/C's. She said in each case they remove the A/C cover and tighten down each of those 4 bolts. It was simple to do, I did it and no leaks since.
I don't know if they loosened during travel or if the factory didn't tork down enough, but I can tell you my leaks appear to be gone. If they come back, I'm going to go up and tighten again. By the way, I'm a novice and was fearful that removing that A/C cover would be complicated. It wasn't. The hood screws are obvious and easy to remove.
