2017 Mustang GT C Pillar Leaking on Passenger Side
I noticed today after a hard rain that there was a small amount of water leaking into the interior of my mustang at the passenger side C pillar between the seams of the plastic panels. The water streamed down the interior plastic panels and ended up dampening the fabric portion of the passenger side rear seat bottom (between the plastic panel and the seat).
Has anyone heard of this issue happening before and know of any possible causes? My only guess is that water is leaking under the rear window due to a bad seal while setting in the rear window.
The car is only 9 months old and this is the first time I noticed the leak (so it may have been leaking the whole time.)
