I joined this group after I purchased my RL with the expectations of showing it off as a proud owner as well as learning more about it from others with more experience. I never imagined two months into ownership I would be pulling the plastic off the carpet near the rear doors and finding water soaked up into the carpet pad. This just blows me away. I showed my local Honda service manager this morning and he acknowledged my issue. A quick search on his computer for "2021 Ridgeline Water Leak" on a private Honda site gave conformation that this is a known issue along with steps on how to resolve it. I am glad Honda has acknowledged this, I just really hope that the 2 days he has my vehicle scheduled for is all that is needed to fix this. Believe me, I have my doubts as I have read the various posts from others experiences. Time will tell. I don't fully regret selling my 2003 Tundra for this RL, but wow, not a great first impression.
