Cybertruck Off-Road Lights Keep Falling Off… As the Glue Holding Them to the Windshield Fails (fuelarc.com)

We’re seeing another sticky situation develop, the same day Tesla recalled 46,096 Cybertrucks to stop them from falling apart because the stainless steel panels are held on with the wrong glue.

This time, it’s the Cybertruck’s off-road light bar that’s flinging itself off at highway speeds. Incredibly, the light bar is also glued in place, so we are wondering if there isn’t another recall coming down the pipe.

Here is one driver whose Cyberbeast tossed his light bar at highway speeds.

They've been doing this since the 90s.

and featuring innovative self-piercing rivet and adhesive bonding techniques for critical joints.

That is a combination of rivet and adhesive for additional strength.

Rivets are placed on the Prowler in a one-second cycle. (One interesting aspect of using this mechanical joining method: sheets of different thicknesses can be put together.) But then there is the issue of stiffness. Which led to the need to utilize epoxy adhesives. So now there is a combination of technologies, with rivets used in combination with adhesives. The result is a structure with a stiffness that’s improved by 40%.”At Chrysler,” says Dr. Saad M. Abouzahr, Prowler Materials Executive,

The adhesive improves the the stiffness of the joint that already includes a rivet. Body panels aren't going to fall off if the adhesive was faulty when there are rivets.

The cybertruck doesn't use rivets, they went even cheaper than fucking Chrysler.

This isn’t the first time a panel has decided it wants to make a dramatic exit from the Cybertruck. In fact, the boomerang-shaped panel above the doors has a habit of detaching itself, so Tesla recalled every single Cybertruck to apply a more aggressive adhesive, along with a stud and a nut, to keep things in place. What’s surprising here is that the front panel is also popping off for some owners.

Bolding by me to make it very clear that the cybertruck didn't even have a single nut or rivet holding body panels on.

That was in the 90s when they first started. In newer cars some parts are adhesive only. The trunk tire well in my Outback appears to be fully held in with adhesive. Apparently it's pretty common for the roofs of cars to be only adhered on. Tesla just kinda went balls out with the adhesive. Or didn't go balls out enough since they're failing so often.

McLaren’s use panel bond for a lot of their cars IIRC

[–] [email protected] 4 points 1 week ago (1 children)

A McLaren is not an everyday driving vehicle, much less a truck that is supposed to be good for going offroad and all the body strain that goes along with it.

A McLaren also has an extemely light carbon fiber shell, which works well with adhesives. Pretty sure the shell sits on the car as well which is the opposite of heavy panels of stainless steel hanging off the sides.

Hey now, DailyDrivenExotics would disagree.

But also, Tesla still has build issues. Is anyone surprised?

The difference is that they did a good job, instead of slapping some elmers on the truck and putting a 100k sticker in the window.
