2026 Jeep Gladiator 4-Door Hardtop Leaking at Not Sure — Expert Fix

Quick answer: A 2026 Jeep Gladiator 4-Door Hardtop leaking at the Not Sure in All of the Above 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 Gladiator; most owners install it themselves in under an hour with no special tools.

I had to put an answer in all the boxes, my jeep isn’t leaking as of yet but when I’m driving it sounds like I’ riding with the windows open. There has to be a way to get a better deal.

Hi DeWayne,

Thanks for reaching out.

What you’re describing—hearing it like you’re driving with the windows
open—is a very common early sign of the same sealing issue that later shows
up as water leaks on the Gladiator.

The root cause is the factory door sealing design. Unlike most vehicles on
the road today, the Gladiator does not have a proper body-side sealing
surface. The door seals are forced to compress directly against painted
metal, which creates small air gaps around the doors and roof interface.
Even before any water intrusion happens, those gaps allow wind to pass
through at highway speeds, which is why you’re hearing that “open window”
noise.

The important thing here is you’re catching it early. At this stage, it’s
not a leak problem yet—it’s a sealing efficiency problem. But it will
typically progress over time into water intrusion if nothing is addressed.

The solution is the same whether it’s wind noise or water leaks: adding a
body-side weatherstripping seal system. This creates the missing sealing
surface the factory setup does not provide, allowing the door seals to
compress evenly and consistently. Once installed, it significantly reduces
wind noise and eliminates the pathway for future water entry.

Gladiator.
