Tesla's Cybertruck may not be so stainless after all::'Literally bulletproof' but needs constant cleaning to stave off corrosion

Lol. Tesla stock down 30% since June.

Tesla, seriously, that roaring sound that’s rising in pitch is y’all about to slam into the ground. Eject the dead weight already.

I mean, to be fair no one will be able to beat geely over the next decade.

yet another feature a regular Car can do better than this truck. its pretty damn sad when your truck fails at basic vehicle properties, before you even get to what its supposed to be, 'truck'. kinnnnda comical how bad this thing is.

such sweet nectar the schadenfreude, i could live off it for days.

I deliver to a Tesla dealership/lemon farm everyday, and they had one on display. It had a smudge on the driver side rear quarter panel that they never got buffed out.

[–] ShepherdPie@midwest.social 39 points 1 year ago (1 children)

You don't buff these things. You have to regrain them by rubbing an abrasive material across the panels in one direction same as a DeLorean.

[–] shasta@lemm.ee 17 points 1 year ago (2 children)

Yeah that certainly reinforces a sense of longevity. Just rub off part of the door every time you have to clean it.

[–] Plopp@lemmy.world 25 points 1 year ago

It's sad that there's nothing your can put on the metal, like something to paint on top of it or something. Like something clear, or in different colors even. Ah here I go again, being crazy with my imagination.

Imagine spending 80K on a truck that starts rusting in days. Oh the poor Elon Musk's s***ers. It might be a really hard blow to feel that betrayed by their idol.

This cybertruck fiasco is getting more ridiculous by the day.

[–] TheFriar@lemm.ee 14 points 1 year ago

What word is supposed to be censored there.

Cult of personality will make them accuse other actors for any of his failures.

[–] w3dd1e@lemm.ee 30 points 1 year ago

lol. Cybertrucks are looking like my sink.

They should invest heavily in Barkeepers Friend. Works pretty well on the sink.

[–] NuXCOM_90Percent@lemmy.zip 24 points 1 year ago (3 children)

Yeah. My understanding is that Deloreans were shockingly rust resistant but were also panels specifically so that they could be replaced.

I don't know metallurgy/material science well enough to know if cybertrucks actually used good quality stainless steel or cut corners. And I can easily see a world where people assume the dirt is rust because of paranoia or just looking for internet drama/clout.

But... Rust or no rust, those cars are pretty fucked. Because they don't even have a clearcoat. And considering we are in the season where roads are covered with salt and sand and cars are constantly bombarded with a highly abrasive slurry at speed, those panels are going to see a LOT of wear and damage.

[–] Death_Equity@lemmy.world 36 points 1 year ago (2 children)

Tesla uses SS301 stainless. DeLorean used SS304.

301 is cheaper, less resistant to corrosion, can resist more force applied to it before failure, formes better in stamping, doesn't tolerate high-temperatures as well.

My guess is they used 301 due to cost and forming properties. Supposedly they use 301 on the Starships, so bulk pricing would help keep production costs low. Had they used 304 the raw material cost and cost of production at volume would be higher but they would be less likely to have these corrosion issues, assuming they aren't welding the panels.

[–] Wogi@lemmy.world 20 points 1 year ago (10 children)

SS301 is a great material. It's workable, ductile, and still plenty hard. It's absolutely perfect for work holding in an industrial spot welding environment.

Why on earth they'd use that for body panels is fucking beyond me. Ok, it's bullet proof, kinda, which is cool I guess? I've never been shot at in a car, I don't know anyone who's ever been shot at in car.

I know lots of people with cars that they don't like to rust. Or scratch tho. Seems like the bigger problem in car design honestly

[–] abhibeckert@lemmy.world 8 points 1 year ago* (last edited 1 year ago) (1 children)

SS301 is a great material

Totally agree. But is this an appropriate use for it? I regularly have to use sandpaper to remove surface rust from my SS301 knife. And I don't leave that out in the rain. It's just surface rust, doesn't damage anything, but it is rust and it's very ugly.

Thankfully with a knife, it takes two seconds to remove the rust. With an entire car? And body panels with areas that are hard to get to? Honestly if I was going to buy a cybertruck I would paint it.

If you want "real" stainless, you want 316, but it's not as strong and would require significant modifications - making it thicker/heavier/more expensive/worse battery range/etc.

[–] Plopp@lemmy.world 4 points 1 year ago (2 children)

Maybe the cyber truck owners will convince themselves the rust is a beautiful patina (and your cat sucks because it doesn't have one!)

[–] Silentiea@lemm.ee 4 points 1 year ago

Don't you talk about my cat that way!

Paint, they always need paint. A lot of science went into that. https://www.youtube.com/watch?v=b_hgPinCZks

Even "good quality" stainless steel can easily rust, as anyone who's owned quality kitchen knives will tell you. Some stainless alloys are more resistant than others -- but exposed to the right conditions they all corrode.

[–] qjkxbmwvz@startrek.website 16 points 1 year ago (1 children)

It's relatively common for nice metal bikes to go the unfinished metal route...if they're made of titanium.

Tesla is just recognizing that each cybertruck owner has different color preferences, so they deliver the cybertruck without any paint or coating so the owners can coat it themselves /s

[–] Copythis@lemmy.world 16 points 1 year ago

I saw one in person 2 days ago. I took a picture, and none of my coworkers think it's a real picture (or that I took it).

It was surreal. I could see it coming from WAY down the road and I was thinking to myself "there is absolutely no way I am seeing a cybertruck right now"

I am dumbfounded they actually made them. I still can't believe what I saw the other day

[–] BumbleBeeButt@lemmy.zip 11 points 1 year ago (1 children)

But really who cares, we are not forced to buy these cheesy blobs of cheap grade stainless. Let the tech bros take one for the team.

[–] Fisch@lemmy.ml 5 points 1 year ago

The people who get in a crash with one probably care

[–] Donjuanme@lemmy.world 11 points 1 year ago (1 children)

Can't wait to see what happens when one gets dinged by road gravel, it's going to be even uglier.

Oh and about that 5-6k coating that will prevent the rust? It'll just prevent you from seeing the rust, don't worry, the rust will get there, it always does, that's one of a dozen reasons why steel has been moved away from for decades.

[–] abhibeckert@lemmy.world 4 points 1 year ago (1 children)

Done properly it should prevent rust. Especially on already rust-resistant metal. And you could use clear paint.

One of the replies in that thread:

I’m know I’m a weirdo but I actually kinda like the corrosion and hopefully the associated patina that will come with it.

Wow.

Holy shit that's not insignificant! Those things are going to be piles of rust in just a few years.

Insane

Isn't that the butler's job?

This is the best summary I could come up with:


CEO Elon Musk first unveiled the electric pickup model back in 2019, claiming that its "ultra-hard stainless steel" body and "transparent metal" glass were "literally bulletproof."

Though beset with production issues and missing its speculative 2021-22 release, its unique polygonal design – as with anything Tesla and Musk-related – attracted legions of devotees eager to get their hands on the steering wheel.

Members pondered whether orange stains could be caused by "rail dust" from certain vehicles being delivered via train, yet Raxar posted some images of his Cybertruck's body after driving it for "2 days in rain."

In a separate thread, another user, vertigo3pc, reported that "corrosion was forming on the metal" of his brand-new Cybertruck after 11 days in the "LA rain," leading some to worry that the steel body was becoming contaminated during production.

The documentation says: "To prevent damage to the exterior, immediately remove corrosive substances (such as grease, oil, bird droppings, tree resin, dead insects, tar spots, road salt, industrial fallout, etc.).

The Register asked Tesla whether it agreed with the description of Cybertruck corrosion as the "norm," and if not, what the company expected to cause the spots documented.
