2019 Silverado Leaking Door Seals

DOUG75 · May 14, 2019

Big Chevy Fans at this house; over the years plenty of Vanduras, K5s, Tahoes and Silverado's.

Thought it was time to trade up a 2015 Silver to a 2019 6.2/10, which is simply amazing but having water rolling down the inside door issue(s).

We picked this up about 3 weeks ago, right off the lot [less than 30 miles on OD]. The wife pointed out discoloring on the inside the door at first glance, but thought that would clean right off with cleaner and would just drive it home and wipe it down.

Well it really didn't come off, and thought best to take it back, or mention it at the first oil change. Although last nigh noticed that rain water drips right in at the door seal (highlighted in the picture). Also realized both doors are leaking at the same spot.

Going back to the dealer at 600 miles now, hopefully they have this issues sorted out by now.

Think my Sierra might have the same issue. Can't really tell yet cause it's been raining like hell here and every time I open the door everything gets wet. The door seals seem very slick. Might clean them with alcohol and then treat them with Krytox.

Just checked the door gaskets: there are two small tabs that are horizontal (inside the gasket) which appears to be the source of the blockage/overflow.

The doors fit nicely, and sometimes need to close it twice to latch. Along with that, the cab is very quiet.

[the rust color is only a refection]

Rain on the east coast -- 70" since this time last year.

Decided to check one more time before going to DEALERrrrrr.. So hand washed and checked the door:

The top gasket looked Ok/Dry but this water is coming in somewhere?

could it be the bottom window seal ?

I cleaned and treated my weatherstripping then sprayed it with a hose. No leak.

I have noticed several times if you open the door quick the water can find its way to the inside in a couple spots.

Maybe that tab on the seal causes it to hold water until you open the door?

Clean with alcohol and then try this.

Mfg.'s also recommend dielectric grease on weather strips. GM also makes an emulsion weather strip lubricant part # 992877. A bottle goes a long way. Krytox is good as well.

I have the same problem and convinced that the 2 tabs are the cause. When water runs down the weather strip it hits the tabs and has no where to go but inside the vehicle

Thanks for the tips!

I went to the dealer and they really gave it a good look with a water-specialist.

The report came back everything is normal. Could be that GM doesn't have a repair-kit at this time.

Thinking something like a additional gasket strip that would attach to the cab, in-line with the door gasket would be an easy fix.

Found it very odd that second gasket uses the inside door panel as part of the gutter system.

FYI this is the new style cab with the shorter hood - which I think is a nice design (appearance wise).

That so called water specialist doesn't know what he's talking about, the only fix I can see is that those 2 tabs need to be removed so the water can go straight down the strip with no resistance

I'm going to the dealer tomorrow so I'll report on what they do
