Lest folks get too carried away, the headline is a lie. The failure is "brake rotor stud separating from wheel hub". Now, sure, that's a serious failure. It's not "wh33lz f411 oFF!".

Everything about this company is cursed at this point. The jeering masses are just as bad as the CEO.

The cars themselves though continue to be really pretty great. Though maybe not the truck.

I'm actually really confused about the language used in the recall; I looked at the Cybertruck manual and the brakes look like a "conventional" design where the studs are set into the hub and go through the rotor, so this failure seems somewhat unrelated to the brake rotors, and the "brake rotor stud" is also the wheel stud: https://service.tesla.com/docs/Cybertruck/ServiceManual/en-u...

I'm assuming it's a misphrasing or typo and the issue is that the stud holes in the wheel hub rotor can elongate, leading to the studs coming out. This can and likely would absolutely cascade into a wheel falling off; I've seen it many times in cheapo endurance racing series - once one stud is loose, the adjacent studs gradually loosen and eventually the wheel separates. If the issue is longitudinal (slotting) it's even more likely to lead to a rapid separation event.

“If cracking propagates with continued use and strain, the wheel stud could eventually separate from the wheel hub.”

That quote is from Tesla, in the linked article. That says the wheel can fall off.

The masses may be annoying, and even sometimes hyperbolic, but they are nowhere near as bad as the CEO
