Q | 2020 Gladiator rear-door leak — what’s the fix?

A: The leak starts at the side, not below the truck. Jeep omitted a body-side seal on the rear door edge. Rain hits that gap, slips past the door gasket, and floods the rear floor.

• Unsealed gap between door frame & tub lets water in
• Rain travels the C-pillar and enters behind the gasket
• Factory gasket was never meant to hold water pressure
• This is a design omission — not normal wear

Fix it: Add the Wrangler Weather Guard™ rear-seal kit to close the gap and redirect water away from the frame.

TL;DR: The leak is Jeep’s design, not your truck’s age.
