So after the second “repair” and about a month of total time at the dealership, the leak is still not fixed. I checked this morning and the floor is soaked again!
I have tested my 2021 Ridgeline Sport sitting outside during rainstorms, with the garden hose, driving in the rain, etc., and I have yet to find any infiltrated water, so I believe my Ridgeline does not leak; however, the precautions that I took prior to having any water issues:
1) sealed the open slots at front top bed corners,
2) taped the front 8 innermost bed drain holes closed,
3) installed a tonneau cover,
MAY have helped to keep any water from infiltrating the interior ! ! !
The North Mountain soft tonneau does allow a minimal amount of water into the bed (
mostly at front below rear window), and a little at the sides; however, the water that does enter into the bed does NOT create any problems with stuff in the trunk
(since it remains perfectly sealed & dry), and just a little water at the low bed floor channels allows stuff in plastic crates to remain dry.
I would try the above measures if I found water in the interior of a Ridgeline BEFORE I would take it to a dealer and allow them to touch my vehicle.
