Windshield seal flew out

Tesla is just using construction methods that the aviation industry has enjoyed for years.

“Jets rely heavily on structural adhesives. Instead of relying solely on heavy rivets and bolts, modern commercial and military aircraft are increasingly "glued" together using specialized epoxies and resin films to reduce weight, lower fuel consumption, and create more durable bonds”

That would be concerning if panels are flying off at highway speeds with the cybertruck and planes fly with the same adhesives .

I prefer a riveted panel despite increased weight .

I do understand that an adhesive would be much cheaper but the cybertruck is not a cheap vehicle .

That’s the one I want … good for mars as well .

No blue glue

Those will the new “blue goo” structural adhesive shouldn’t suffer from panel adhesive issues. It was an assembly line running change made in 2025. The older structural adhesive was grey in color.

I noticed signs of welded studs, like at the base of cantrails, on that front piece of my '26.

I have a similar issue on my right side front windshield where that rubber trim is loose and can move up and down freely. It's never flown out on its own. I don't need to put tape over it. My left side is nice and tight like JesseG's post where it doesn't move. I have an upcoming service appointment to address it. I had my cantrails serviced last year to upgrade from adhesive to bolts which is when I'm assuming that trim became loose and was overlooked.


They swapped to aerospace blue glue which is industry standard for airplane construction:

I have not. One side is definitely wider than the other. I really hadn’t noticed a problem until this seal thing happened.

The problem is they had to waterproof the truck after having the steel exterior. They just jammed in some rubber seals in various places and the sun/heat are starting to wear them out as the trucks get some age. Hoping that enough of them go within the 5 years that Tesla does a voluntary recall otherwise it will be a long term maintenance thing that owners have to do on their own dime.

It seems like Tesla used the same adhesive as their other vehicles, which is also quite strong (if Munroe is to be believed). The difference with the CT is surface prep, since bare stainless likely has different adhesive properties than aluminum and mild steel.

There's also weathering: external parts can easily get moisture inside any gaps in the glue, which can freeze/expand, weakening the bond.

Someone here awhile back suggested that applying silicone caulk to the perimeter of the cantrail glue could prevent intrusion and extend the adhesive lifespan, but IDK if that is merely conjecture.

It shouldn't be necessary anymore after the change to a stud and nut holding it in place. This blue adhesive holds airplane parts together without rivets. It should be able to handle moisture.

What year? What series of VIN?

2024, vin 9798.

I've known of structural adhesives in auto use for well over 40 years. The trick with them is proper preparation of the surfaces to be bonded, and that they are bonded at the right temperature. Also the surfaces to be bonded have to be compatible with the adhesive. Many structural adhesives get stronger and harder to remove over time. My guess is Tesla didn't do the right preparation for the surface preparations used for the parts. Bare stainless steel is different that etched stainless steel for surface adhesion. They needed an adhesive that could handle just cleaned stainless steel. Another possible issue is people touching the surface between cleaning and adhesion of the part. That could easily happen as the vehicle is being built.
