Hi Travis,
Thanks for reaching out and for the detailed explanation.
What you’re describing on your 2018 JL 2-door soft top is actually very
common, especially when the Jeep is parked nose-down on an incline during
extended heavy rain.
When the vehicle sits front-end down, water naturally channels forward
toward the windshield, A-pillars, and upper door corners. Since the JL does
not have a proper body-side sealing surface, the doors are forced to
compress directly against painted metal. Painted metal is not a consistent
sealing surface, so during prolonged rainfall, water slowly works its way
through small gaps around the upper driver and passenger door areas.
That’s why you’re seeing pooling on the driver side floor and moisture
developing on the passenger side as well. The water typically enters higher
up near the A-pillars and roof transition areas, then travels downward
behind the trim and seals before soaking into the carpet.
Soft top models are especially sensitive in these areas because multiple
sealing surfaces meet together near the windshield frame and upper door
corners.
Even though the factory seals may appear to be in good condition, the issue
is usually not the seals themselves—it’s the lack of a proper gasketed
sealing surface for them to compress against.
The most effective long-term solution is adding a factory-specific Jeep
leak fix kit with body-side weatherstripping. This creates the missing
sealing surface the factory design lacks, allowing the door and soft top
seals to compress evenly and consistently. Once installed, it eliminates
the gaps and resolves the water intrusion issue at its source.
Below is a link to the leak fix kit that will solve your issues.
If you have any additional questions, feel free to reply to this email or
contact me directly.
Best regards,
Tony
