2016 Jeep JK 4-Door Hardtop Leaking at Driver Door — Expert Fix

Hi Andrew,

Thanks for reaching out and for the detailed description.

What you're experiencing with your 2016 JK 4-door hardtop is a very common
leak pattern on these vehicles. The fact that the Jeep sat through three
days of heavy rain and you found a large amount of water on the driver
side—including underneath the driver's seat and into the rear carpet—is
consistent with water getting past the upper door sealing area and then
traveling underneath the carpet.

The passenger side being damp as well is another indication that you may be
dealing with the factory door-sealing design rather than one isolated
damaged seal.

The root cause usually isn't the condition or mileage of the Jeep. Even
with only 50,000 miles and having spent much of its life garaged, the
factory design itself can allow this to happen. Unlike most vehicles on the
road today, the Wrangler JK does not have a proper body-side sealing
surface. Instead, the factory door seals are trying to compress directly
against painted metal.

Since painted metal isn't a consistent sealing surface, small gaps can
develop around the doors and allow water through during prolonged or heavy
rain. Once water gets inside, it can travel underneath the carpet, which is
why you can end up with wet areas well behind the point where the water
originally entered.

Our body-side weatherstripping creates the sealing surface that the factory
design is missing. It allows your existing factory door seals to compress
against a consistent gasketed surface rather than directly against painted
metal. The included drip strips also help redirect water to the outside of
the Jeep. As an added benefit, properly sealing these areas helps reduce
outside wind and road noise.

I would also recommend getting the carpet and padding underneath it
thoroughly dried. The padding can hold a surprising amount of water even
after the surface of the carpet begins to feel dry.

Here is the correct kit for your 2016 JK 4-door Hardtop:

Select Hardtop when ordering.

Keeping an eye on it the next time you wash the Jeep is a good idea as
well. If you have any questions before ordering or during installation, you
have direct access to me 7 days a week. I'm happy to help you get the Jeep
completely sealed up.

Best regards,
