R1S tailgate sealant glue - melting in warm weather
Recently did a drive though warm country in AZ (100-105F) and after the first day started getting “liftgate obstruction” error. Wasn’t sure the issue until the daytime I can see the weatherstripping literally came off the top and is in the hinge. Lookin closely, the adhesive Rivian is using clearly is not strong enough to tolerate the temp from the sun on the roof.
Put in a service ticket. Rivian AI agent told me this is a “known issue”. Second issue with our 2026 vehicle regarding insufficient adhesive causing trim to come loose.
Even though there is now a gap from the roof, I don’t think it will affect waterproofing (rain would flow around the gap on either side)
Any other warm climate people deal with weatherstripping melting/coming loose? Clearly Rivian needs to reconsider the adhesive they’re using. Also wondering if there are other “problematic” areas that I should proactively examine before the mobile tech comes.
