"Wet" smell, possible leak?

Skeeter McSkeet · May 31, 2018

Well, we've been getting absolutely hammered with rain the last couple months. I've started to notice on and off randomly a wet smell in the truck after a heavy rain. I had an old oldsmobile in high school that had a leak when it rained in the passenger floor board, and it reminds me of that same smell. I've thoroughly checked the headliner, front and rear flooring, sunroof seals, window seals, etc. Curious if anyone has had any leaks, and if there are any areas I should keep an eye on for them beyond the shark fin that seems to have an issue with leaks. Can't seem to find a single damp spot in the truck.

My '17 had a leak and the dealer had no clue where for... (not sure why couldn't locate). It ended up shorting a lot of my electrical. 4x4 would engage when it wanted to. Stab Track on/off... steering issues... etc... They bought it back. Last week (after 6 weeks of new truck) water was pouring in. Was for the antenna AND the windshield seal. Take your A pillar off and see if there is water in there. Then take up your carpet and see if floor board is wet. (carpet has rubber coating so it will not go through the carpet. Been 2 days... I'll update again.

I wonder if my 17 has the same issue? My wife complained about a "mop water" smell the other day... I haven't noticed anything yet, but I'm in it a lot.

My co worker had this issue with his 17, and my 17 just started to smell as well. After a quick call to the dealer, they stock the parts for the repair similar to how they do for a recall. They told me 2 hours for the fix, up to 6 hours if they find any other leaks....

Pull up the carpet on the pass side floor and see if it's wet under there. I was getting water in mine and found out the wire harness grommet wasn't sealed all the way and it was letting water in and it would trickle down to the floorboard. I found it when I was installing pgamboa's DL3 kit.
