2021 Jeep Gladiator 4-Door Hardtop Leaking at Not Sure — Expert Fix

Hi Brittney,

Thanks for the additional details. What you’re describing on your 2021
Gladiator is a very common pattern of water intrusion on these vehicles.

The water flowing from the door jamb area into the kick panels, along with
both front floorboards becoming soaked and the rear window leaking at the
upper inside panel, all point back to the same root issue: the factory
sealing design.

Unlike most vehicles on the road today, the Gladiator does not have a
proper body-side sealing surface. Instead, the door and roof seals are
trying to compress directly against painted metal. Since painted metal is
not a consistent sealing surface, small gaps develop around the upper door
corners, A-pillars, roof rails, and rear hardtop sealing areas. During
rain, water is able to work its way past those areas and travel down behind
the interior panels and into the floorboards.

That’s why you’re seeing it show up in multiple places at once. Even though
the leaks appear separate, they are typically all related to the same lack
of a proper sealing surface for the factory weatherstripping 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.

Best regards,
