2015 Fit EX. I was surprised to see water on the floor by the front seat passenger a few weeks ago. I thought it might have been because I had left the window open a bit. Despite almost daily heavy rain, there was no more water on the floor till this morning. Fortunately, I have rubber floor mats with rolled up sides so the water didn't get onto the carpet.

Is there a particular spot where this kind of leak occurs?

 

3rd gen Fit's are known to leak water through the front doors. You can search for fixes in this group.

 

Thanks for that. I'll take a look.

 

EX, which means it has a moonroof, right?
Consider that possibility, also.
The drain hose from moonroof can get clogged with debris.
They sell specific tools to clear out these, but I've no idea how well they work.
I always park in the garage and never even open the darn thing (LOL).

 

Thanks. I'll take a look.

I generally just lift the back of it open.
