I feel for you . So so annoying . My water drains into the smugglers bay .
Odd, I can spray a hard stream of water at the Smuggler’s Bay, but it’s all caught by the trough and drains away.

Oh man, thanks for this. I'll be testing mine and sealing it off this is where it's leaking from. My tonneau has been "reworked" three times by the service center and it's still too wet to keep, say, suitcases back there on a road trip.

Edit: Just tested. Yup, just watched water run off the glass right through the gap between the glass and the applique. Hot damn.

Edit2: That particular windshield rubber seal is currently on sale at Amazon. I have never been so excited to stick on a piece of tape in my life.
The amazing thing is how bad knowledge management is at the Tesla SCs. Numerous well documented problems and fixes, and the techs there seem dumbfounded with every issue you bring up.

Same. Have washed the truck a number of times with the tonneau open and pressure washed the bed out many times with no water getting in the smugglers bay. Stays completely dry.

Would bathroom clear caulking around the aero flap fix the issue? And this solution is not permanent so no damage to the truck.

Didn’t help me either,but put an auto glass seal between the appliqué and roof glass and it did the trick. Appliqué edge abutting the glass needs to be cleaned with alcohol. Using an adhesive promoter/enhancer will allow a tight seal. When applied looks like it’s part of the appliqué . It’s an inexpensive and effective way to minimize the drips.

I tried the video weatherstrip and it didn't fix it. The strip with the middle part removed was far too soft and let water beads in through that curvature, instead of creating the gutter that the video spoke of. Couldn't withstand regular rain, was a sieve in a soft cloth car wash.

Then I added an additional weatherstripping bulb type, that also let water beads in, albeit less and slower.
Today, I gave up trying to make it invisible from the outsideon the underside and stuck on this exact windshield tape on the seam between the roof glass and the appliqué. Cleaned it up with the alcohol wipe it came with, made sure it was dried out with a bounty paper towel and stuck it on end to end, including over the side roof appliqués. Poured a big bottle of water on the roof after (winter here, hoses are already stored away and spigots off) and watched the water bypass the seam and continue towards the tailgate taking a normal drainage course. This might be the first time since getting the truck in October that my rear window is dry.
Only got some drops in after opening the tonneau cover with water on it.

I am impressed and grateful for this fix, @Art138 .
Hopefully it stays stuck on. Didn't use any adhesive promoter as I didnt have one. Worst case scenario, will add some clear silicone to the underside if I see anymore drips. Don't need the appliqué to be removable, as I don't have the tent or anything like that.

Hoping we can all soon get the rear edge seal for the roof glass that I have seen on the parts portal to fix it once and for all:
https://parts.tesla.com/en-US/catal...eference=53814d7d-8409-488b-8ad7-63db6b1c11e9 rear edge seal, currently priced at 0$ so cannot order it.

Glad it worked for you too. I have had mine for almost a year without issues. Actually, the heat of the sun here in S Fl made the adhesion better.

Awesome to hear it's still on and working.
Unfortunately for me, here in the Northeast we are down to single digits at night, so no heat would help me now, unless I take a hair dryer to it :D

Yep, and you can definitely see the new seal in the service procedure. It's super beefed up and rubber, with a slot where the appliqué seal would go into. Mine didnt look anything like that...it was a super duper thin black foam/not even close to rubber or the more expanded foam that others have like the video. My build date is mid August of this year...super weird. SC didnt find anything "missing" on the seal there and said up to a third of the bed can get wet and be within spec. Ridiculous. I bought the Tesla cargo mat that is a carpet style to give it a more trunk like look and feel and it would just get soaked...

I used this. Insert this on the weather seal touching the roof glass. Use the existing seal as the anchor for this door edge protector. It seals that area real tight. Tesla's weather seal isn't cutting it (I have a August 2025 build), water still got in especially during power washes. I tested it through heavy rain and power washes, not one drop got in.
