I've noticed a musty smell after a hard rain here in Texas today and after checking the rear hatch area noticed water around the charcoal canister wiring in the trunk under the carpeted liner... I pushed down on the rubber sealer around the wiring back there and saw bits of water coming out. I didn't see this covered in the video though so I thought I'd ask here about that and how to remedy it or if it'll drain in time and its just due to an excessive amount of rain lately or something.

Recently joined the leaky boot club, and after looking around it appears the water is seeping... upward? from these clip things, on both sides of the boot but the right one seems more leaky... Does anyone know what they are / where they lead? Second spot seem to be further down the right side where it looks like the sealing goop wasn't evenly applied. Current plan is to RTV around all of these things but kind of worrying whether this will just trap the ingressed water between some metal and cause rust.
Had a bad three day heavy rain storm last weekend and have standing water in the foot wells (worse on passenger side). I had to pull the carpet today as it is completely saturated. I ran a hose over the rear hatch and there does seem to be some intrusion on the driver side.
With it being all the way to the front foot wells I may check the door drain holes. This youtube video shows some spots we can investigate for possible leaks. Posting this mainly as he points out how water can defeat the front door seals. I know someone recently posted having that exact issue. @FiestaSTdude

Final update (I hope). After performing above I still had a tiny bit of water intrusion in the trunk, but not nearly as bad. I noticed a drop forming on the upper white grommet/insert that the top tail light gets screwed into! Took some clear silicon to all of the grommets (two plastic & two rubber) and that seems to have fixed it!!! Woohoo! I can finally put my carpet and rear seat back in the car.
Anybody ever try something like these in the trunk floor?

Joined the failed tape club. Tape is of course, very temporary. Engineers would know this, so this was obviously an intervention by the bean counters because square and ovoid grommets are more expensive. 🤔 Either that, or there was a part shortage and they didn't want to halt the production line. There are a pair of holes back there that do have a grommet installed. So it's senseless as to why the remaining wouldn't have them.
Warning to others. Do not let any lubricant touch your vents. In the wonderful video that @Nitelife posted, he repeated what he was told about some of the vents dry-rotting. So I applied some silicon spray as a preemptive measure. That ruined them. 😮 Otherwise they were perfectly fine. The rubber immediately expanded. Motor oil or any other effective oil/silicon based lubricant will have the same impact. The effect is permanent. I had to order replacements and that took about a week. As a temporary workaround until replacements arrive, may be able to use plastic wrap around the inside of the vent. But that will likely get sucked/blown out. In addition, plastic retention tabs may break every time one pulls the rear bumper off. The vents must close for multiple reasons. Keeps out exhaust, insects, excess humidity, water (when moving), and sewer gasses depending on where you park. The sunroof troughs drain exits right below these vents.
Photos...
Cleaned areas with rubbing alcohol. Used metal tape to cover the holes.
Much more appropriate for this kind of application. Layers will prevent puncture/blow-out.
For the white plastic wall/screw anchors, I used silicon o-rings. (compare top to the bottom)
Went around everything with gasket maker aka RTV sealant. Did the vents once they came in as well.
If you're nit-picky, use a dark colored sealant for the two on the left as they may be visible around the tail light.
The Spec-D tail lamp grommet BTW, also has an O-Ring in there that makes them lock in there exceptionally well. No need for sealant there in my case.

I did the same thing. Turned out mine was actually leaking from under the drip rail molding. So that is a tip for those chasing a leak.
For the tape, I used RV Eternabond - it is a rubberized tape that will literally last longer than the car.
For sealing, also used an RV product, Geocell Proflex. stays flexible and sticky, non-silicone based product. Also lasts a long time.
While in there, recommend changing the mount bracket for the bumper, as most of the teeth broke off mine when removing the bumper cover.

If anyone has some photos related to this, it would be a great addition to this thread.
Yes, order ahead. I was fortunate enough to have lost only a couple of clamps during removal. The OEM bracket is riveted in there. So there will be some work in figuring that out.

I didn't get any of those broken, but I did end up stretching the tab at the very bottom of the bumper skin where it's attached to the wheel well and so now it sits ever so slightly not flush with the body panel. Its a part of the bumper skin so I'd need new one to fix that. I'm going to try getting one those tiny clamping clips for paper and apply it from the other side to see if it can take up the extra slack.
TLDR; careful when removing that one, maybe wiggle something flat in to disengage it as you're applying force

Removing the wheel well liner exposes the clip in the wheel well. I was able to hold in the release position from the backside, while pulling on it. So avoided breaking that one. Fortunately the ones that broke weren't on or near the top or bottom.
The body line for my bumper cover is a tad tweaked so it is rubbing against the metal body panel. This has breached the paint on the body panel; so rust is starting.
Following your mention, I tested it on the old one. It did not make the rubber expand. 👍

I’ve posted elsewhere about my trip to the junkyard today but I learned the other day when replacing my taillight bulbs that I had one piece of tape and one totally empty hole where there clearly had previously been tape.
Found a Fiesta hatch at the junkyard, took the silicone grommets out from behind the taillights, slapped em in, and then put gorilla tape over them just for good measure. That should solve whatever water intrusion issues I was having, which seemed to be mild.
