2018 Honda Civic — footwell gets wet only after heavy rain

BrakeBuilderCommunity StarterMar 11, 20262018 Honda Civic SiRaleigh
2018 Honda Civic Si, about 41,000 miles. The car stays dry in normal rain but after a long storm one front footwell gets damp. Door seal looks okay. What drain/seam tests would you do before tearing the interior apart? I am in Raleigh.

Don't overfit one forum story to your car. If it still isn't clear on the 2018 Honda Civic, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. I'd want that in writing, not as a promise. I'm keeping receipts and dates in one folder.

Owner notes beat generic advice here. On the 2018 Honda Civic in Raleigh, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “footwell gets wet only after heavy rain,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. Climate here is different, so treat that as a local data point. Wrote this up on my lunch break.

I'd keep this practical. Verify the cheap/easy branch on the 2018 Honda Civic before a big repair or a big spend. Then you'll know the next fork. I'd want that in writing, not as a promise. Your commute and mine probably aren't the same, but the test still applies. I'll update if anything new shows up.

Same neighborhood, different next step: A second data point from another 2018 Honda Civic owner helps more than a generic diagnosis. Then you'll know the next fork. If you share a photo of the worksheet, easier to sanity-check. This is the version I'd tell a friend.
