Hey any resolution on this? My few days old JLUR is doing the same thing. After yesterday's rains, my front passenger floor was wet - also in the same area my JKU used to leak! Haven't had a chance to take a look at the seals or reseat the panels yet, but figured I'd ask if the header seal fixed the issue.
Im not really worried about it as the Jeep is waterproof and my '12 JK did this for 6 years and 103K miles! But since the JL is new, figured I'd try to address it.
