2017 Jeep JK 4-Door Hardtop Leaking at Not Sure — Expert Fix

Quick answer: A 2017 Jeep JK 4-Door Hardtop leaking at the Not Sure in Heavy Rain is almost never a bad door seal - it is the missing body-side weatherstripping Jeep left off the body, so the door seal has nothing to compress against. The permanent fix is adding body-side weatherstripping for the JK; most owners install it themselves in under an hour with no special tools.

Hi Bob,

Thanks for reaching out.

What you’re describing on your 2017 JK 4-door hardtop—occasional water on
the driver side floor and under the driver seat during heavy rain—is a very
common issue on the JK platform.

The reason it can seem inconsistent is because the water usually enters
higher up around the driver door, upper door corner, or A-pillar area, then
travels underneath the carpet and padding before collecting on the floor or
under the seat. That’s why many owners aren’t immediately sure where the
leak is actually coming from.

The root cause comes down to the factory sealing design. Unlike most
vehicles on the road today, the Wrangler JK does not have a proper
body-side sealing surface. Instead, the door seals are trying to seal
directly against painted metal. Since painted metal is not a consistent
sealing surface, small gaps develop that allow water to work its way into
the cabin during heavier rain conditions.

Even if the factory seals appear to be in good shape, the issue is
typically the lack of a proper 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 roof 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.
