I have a new to me 2005 MDX that I’m trying to troubleshoot water intrusion when parked. It’s been parked for a couple weeks and we’ve had a lot of rain here lately. I just went out and discovered it had turned into a swamp on the interior. There was over an inch of standing water on the front drivers floor and also some on the passenger side. I’ve checked the sunroof drains and they are clear. It appears that this is the classic seam leak at the firewall/fender/A-pillar that ends up leaking into the cabin. I’ve done a bit of research and came across a vague fix where someone quick fixed this issue by drilling a hole at the bottom of the outer hinge panel (at location of red arrow shown in attachment). The idea is this allows the water that does seep through the seem to drain before it fills that cavity high enough where it comes in through the hole in the interior kick panel (next to e-brake on driver side and behind fuse panel on passenger side). I’m curious if anyone has attempted this repair?
