I have noticed this for some time now and can't quite figure out whats going on. On rainy days after getting in the car and driving for 10 minutes or so I would see a droplet of water fall down from the top of the window close to where it curves down toward the front of the drivers door. I had always figured it was a bit of water that had got in after opening the door and was just hanging there waiting for enough force to lodge it free to fall on my leg. Last week I was driving and sure enough I get the droplet landing on my leg, folowed by two more over the next 10 or 15 minutes. You think I have a leak?

 

you should check the seals around the door. I had this happen on my previous CRV and the reason was because the door seals wasn't pushed into the door properly. It was most likely from me conditioning the rubber during car washes and it just got loose over time. Good luck!

 

can't say for sure, but Honda's do have problems with rain drainage. If you ever open your window just a bit and it's raining, plan on having a waterfall come in and soak your left leg and the window switches.

The rain channels on the windshield and roof do a shitty job of keeping rain flowing to the back of the car, now down the side.
