Condensation / Moisture in Rear Under Floor Storage Area

Maybe they got the one with the port-a-potty installed.

Oh snap, I forgot about that debacle. I was built right around then too. Just so people aren't confused that was Chrysler flooding not MAP. I think MAP only had a couple inches of water.

I checked the storage compartment yesterday and nothing inside and it rained, so thinking probably not a leak. Haven't checked yet today.

Yea, I’m aware they didn’t flood at MAP but that much rain and wind just a little zipper or Velcro left undone and next thing you know water is sitting in spots for weeks that you never see especially if your bronco didn’t have to be shipped far! Been through a few hurricanes here in the OBX/ Virginia Beach area water always finds a way in. I hope that’s all it is a 1 time thing for ya! Mine will be here soon as well!

Update as of July 19. I left the plugs out and all items including the jack out until yesterday afternoon, so 3-4 days airing out. I have not seen any moisture in the storage area over the last day.

It rained during the days I had the bins empty and I checked and didn't see any water or moisture in the storage area, so pretty confident there isn't a direct leak.

I think something I was storing in there maybe had some moisture in it and being right under the exhaust the storage area would warm and cool at different rates than the outside air and cause condensation. I think owners should be mindful of what they put in the underfloor storage and making sure it is dry. I am sure people will put tow straps, tie downs, etc. That could get wet from normal use in there and cause some issues.

Start the process of taking this issue to the dealer ASAP . My wife, who at the time was my GF bought a brand new Olds. It was on the showroom floor. I sat in it and I immediately said, “ if this is the smell of a brand new GM , the I am glad I only buy Fords”. 10K miles later and six trips to the dealership in order to get tha car from flooding inside whenever it rained, we used the Lemon law, and got back 95% of our money ( paid cash for the car) minus the tax. I told my wife, they probably took the car and sent it to Arizona to resell. Don’t settle, follow through to the end. It is worth it.

Goodness I hope that was your one and only vow at the wedding

I seriously doubt this is from condensation. You need to try to duplicate the condition that it was in when it was leaking. Have someone hit all the seems with a garden hose while someone else is inside of the stripped out cargo area.

All the people that said “I’ll wait after they get all the kinks out” are probably laughing at these threads. 🥲

Might as well get 99’d with a mod top, then switch in 2023.

so I guess with the muffler being below that using it for a beer cooler is out now.

I brought a demo unit home to test fit it in my garage and noticed the same issue with condensation inside the rear jack storage area. It does seem like it’s an insulation issue and there is a difference in temperature allowing for condensation.

I have the same thing. Noticed some condensation right after I bought it when I first opened the compartment and thought it was left over from production, for some reason. But then checked the other day (have had it less than 2 mos.), and there was condensation all on the underside of the lid, and standing water in the bottom both in the storage compartment and the jack storage space, and the bag holding the jack bars was soaked.

i cleaned and dried it out and took all the stuff out of there, and closed it and left it overnight closed. By mid morning—with no overnight rain—the underside was again moist and there was light condensation throughout. Since it was not running and no AC, and there was no rain, I can only imagine this is partly if not entirely due to ambient temp swings from morning to 80-90 degree days in the sun causing condensate. I bought some marine desiccants to see if those help.

Thanks for figuring that out!
I guess i need to stock up on these and fill up that tray with it

I bought these off Amazon to help with my condensation issue:

Last summer my mom traded in her 2012 Explorer for a 2019 with only 12k miles on it. I looked it over from top to bottom and noticed it had almost the exact same thing happen. I ran a Carfax and didn't see anything. I'd most definitely agree with the different temperature swings as being the cause.

That's a lot of water. Let me know how those dry packets work.

One thing I did that seems to help is just pull the two drain plugs so the temp can equalize quicker. It's been a little better but still not perfect.

Further update—several days with no rain, and again this morning, after the sun started hitting the back window, light moisture in the storage compartment (mostly at the edges) despite it being completely dry the night before. This is not a leaking issue. It is a temperature variance issue.
