Hi all - took my BRZ out of the garage for the first time since November 8th. Drove to get lunch and when I put up my sunshade, I noticed both visors were stained, inside and out. I felt the headliner and it felt cool/damp in the front area but dry in the rear. Visually I could see a very slight line (suspect water line) right above the front row seats across the entire width of the headliner.
The stains you see on the front visors do not wipe off, but the line on the headliner seems to have faded and the headliner no longer feels damp since I left the car parked in the sun for a few hours. Some have proposed that there's no water leak, but rather it's off-gassing.
I popped off the two a-pillar covers and the dome light cover to check for water staining or other evidence of a leak - nothing found. I felt around the headliner edges where I tucked in radar/dash cam wires and it seemed dry. Aside from tucking cables and adding a windshield tint strip, no other mods have been done to the car in that area and I hadn't noticed any issues in prior washes.
2020 BRZ w/1,968 miles.
I plan to take it to the dealer as soon as they have an opening.
Thanks for any insights or help!
