I notice when i was vacuuming the carpet. driver side carpet was wet.
i vacuum and dry it and seal the bottom of the car with under coat waterproof sealer.did the roof line too. I notice poor welding and seal job on RDX.
It rain for 3 days here in PA notice wet again. Is not comming from the top of the car. think is comming from the bottom. this time i seal the inside with Silicone rubber all over the edge. We are getting more rain tomorrow.
Will post what happen next.

 

WOW I have not heard of that before. I wouldnt monkey around with any quick fixes. Take it to the dealer to look at.

 

when the master brake cyclinder breaks...that will lead to wet carpet depending on its location in the truck..thats my first guess....usually fluid of some kind

 

...if its not an actual water seal leak type thing

 

there is a tsb for this.
