Water in trunk?

Fortunately I do not have this problem and I have driven through some heavy rains.

I have had it in my 1.5 Roadster. The water does seem to come in on the left/driver's side of the car. I haven't figured out where it is getting in, but it seems to only ocur when I wash the car and even then it is sporadic. Normal rain even hard rain does not cause it to leak.

I notice that I'm getting water into the trunk area, particularly on the left edge. Anyone else have this problem? Maybe I just need new seals.

Yes, my car had that problem. Usually when washing the car, rather than from rain. Tesla service fixed it for me under warranty. They don't need to replace the seals, just raise them and/or adjust the deck position.

That seemd like an easy fix. Do you recall how any of the seals on that side looked like prior to the service?

I don't recall a noticeable difference. The seals slip onto the top edge of the bucket that forms the trunk. The way they can raise the seal is to take it off, slide some edging onto the edge of the bucket, then put the seal on back over the edging. Thus, it looks the same before and after. At least that is how I think the process went.

Try talcum power on the seal before you wash.

Thank you for your post on this and for the pictures. My Roadster trunk has been filling up with water after every heavy rain and I couldn't figure out the source. I'm going to seal the trunk bolts as you suggest, but I'm just curious how water would be moving "up" from beneath the trunk? Did Tesla explain that at all?

I'd suggest getting a UV penetrant dye (the type used to find leaks in pipes etc, talk to a local garage where they do aircon/HVAC regasses), put that in a heavy duty sprayer and wash the trunk down several times. Then with a UV lamp see if you can see where the penetration is occurring - I've used this method to follow leaks into all sorts of things, from MG's to satellite assemblies.

Once you have the source there could be various solutions - either new seals, or if a crack (not impossible) in the epoxy trunk, then use some impregnated epoxy tape to seal the fracture - that will give mechanical strength in addition to sealing the leak.

I found that water can enter the trunk/boot area via the bolts securing the rear spoiler in place.

I sealed these 4 bolts and now no water intrusion

I had a similar issue but my water was coming in through the rear gasket. I adjusted the latches so there was a tighter seal.

I also have experience with water in my trunk:



I found out that water came in through the back of the trunk.
On one place where there was no screw.
And through the trunk lighting:



I put the screw back in with a rubber ring behind it.
And put also 2 rubber rings behind the 2 other screws that are in the picture.
And I placed a rubber "mat" between the trunk light and the trunk.
Still only a little bit of water coming in near the trunk light, when I spray a lot of water in the trunk.

Basically what we have learned today is that water intrusion in the trunk can come from ANYWHERE

Do not forget that the temperature in the trunk varies a lot through the temperature of the electric motor nearby (more then 100 degrees Celsius while driving) and the PEM
This causes a lot of condensation in the trunk and is not a leakage

Are you sure? I live in a humid climate but I've never had condensation in my trunk. Or leaking in over 60k miles. OK, I know that doesn't compare to what you've done, so maybe I just haven't seen it yet?
