Tesla Cybertruck May Have A Rust Problem::One of the more standout qualities of the Tesla Cybertruck is its bare stainless-steel body. The stainless-steel body gives the Cybertruck a unique design, but

One way to keep the Cybertruck’s stainless steel body from rust and damage is to get it wrapped. Interestingly enough, while Tesla saved some money by not clear coating the truck’s body, the automaker offers a “Satin Clear Paint Film” and a “Color Paint Film” for the Cybertruck that costs $5,000 and $6,000. The “self-healing, urethane-based film” protects the truck from scratches and corrosive substances. After hearing about the issues that current owners are having with rust and corrosion on their trucks, we’d consider the film to be a must-have for Cybertruck owners.

There's a fix, it just cost 6k...

Selling you back the clear coat they never gave it.

The car equivalent of launch DLC that should have been in the base game

“self-healing, urethane-based film

Urethane? You mean paint?

Its like these amateurs are figuring out why we paint cars... its because Urethane protects the metals from rust. I guess they could use Urethane film instead, but that's probably just not as good or efficient as paint...

They keep using the words “stainless steel” which is an alloy created to be rustproof by removing the iron out of it. So how exactly is this stainless steel if it rusts?

[–] ChapulinColorado 39 points 10 months ago* (last edited 10 months ago) (8 children)

There are different qualities of stainless steel. Remember kids, it’s stain less not stain never.

[–] [email protected] 7 points 10 months ago (3 children)

I guess there is still iron in it. Looks like they didn’t use an alloy with enough chromium for the application.

[–] [email protected] 10 points 10 months ago

Tesla, cutting corners?! Say it isn't so!

I'm being pedantic here, but stainless steel still has iron in it. The addition of chromium forms an oxide layer on the surface that prevents rust. If the body is rusting, that means they used a shitty grade of stainless. Stainless with an appropriate amount of chromium (and nickel) is expensive as fuck.

Stainless has chromium added. Iron is still the main element. Different stainless steels have various other elements added, like molybdenum. There’s a wide range of SS for various purposes depending on their formability, weldability, corrosion resistance, heat treatment or precipitation hardened. Some are mildly magnetic (400 series), others not (300 series). Big range of cost too. Not sure which one they used. There’s also a finishing process called passivation that should be used to reduce the likelihood of corrosion.

it rusts less, far less in fact, but it still does rust.

Also there are different grades, i bet they cheaped out

I think a lot of people who bought this expected stainless steel not to rust

It wouldn't surprise me if musk thought this as well

[–] camelbeard 29 points 10 months ago* (last edited 10 months ago)

Musk probably said something like they used a revolutionary new type of stainless steel, designed for spaceX rockets. Have you ever seen rust in space? No because it's that revolutionary, and we all know space is filled with water and oxygen.

But isn't Rust supposed to be great and memory safe?

[–] jerrythegenius 7 points 10 months ago

Shoulda used nim or something

The owner must immediately remove road salt? The rust belt is nothing but 3 piles of road salt in a trench coat for half the year…

[–] [email protected] 21 points 10 months ago

Almost all of Canada is a no go zone for that thing at least 3 months of the year.

"remember when cars rusted like shitballs? What if we sold trucks that did that?"

"people buy our cars and their panels have these gaps you wouldn't see in any other manufacturer. And our cars, they seem to have a taste for the blood of children. People keep buying the cars though. We're doing something right and it's sure as hell not making cars"

"yeah but look at the stock price"

"good point"

Money fight!

[–] dragontamer 31 points 10 months ago* (last edited 10 months ago) (2 children)

“yeah but look at the stock price”

Uhhhhhh...

I think the stock market noticed this was a shit car guys. Look at that steep drop from December / January into February.

[–] [email protected] 13 points 10 months ago (1 children)

But the good news is that if they give Musk 25% ownership he'll agree to keep running the company.

From what I hear, the panels of that car are sharp as fuck.

Bot has great comedic timing.

So they used the wrong grade of stainless?

FFS add it to the pile of embarrassment

[–] SkyezOpen 24 points 10 months ago (1 children)

Worse, it's a proprietary tesla steel.

[–] [email protected] 31 points 10 months ago (1 children)

Given their current track record for QA I'm going to guess that it's the lowest grade they could still call stainless

[–] [email protected] 11 points 10 months ago* (last edited 10 months ago)

Depends whether Elon made the decision or Captain Sensible snuck in and did it while Elon was playing with Twitter.

It's not like Tesla doesn't have smart people, they just don't get to make the decisions some of the time.

Rust proofing. Wasn't that something dealers would add in as a scam for a few bucks?

Once again, there is a Seinfeld reference here.

Yeah, but when the hell is it going to get wet? You don't drive these things outside.

[–] Donjuanme 21 points 10 months ago (6 children)

I saw one in the bay area Sunday, it absolutely had a distinct mud/baby-poop patina. Couldn't believe how much it stood out, how non-practical it appeared to be as a truck (I'd take a Rivian r1t any day for functional truck), and just how rusted it appeared to be (I thought it had driven through mud at first, but it was way too evenly dispersed), it couldn't have been a year old, or seen more than ten days rain.

Good news, everyone!

Well, the sooner these fugly things rust back into the earth, the better.

[–] [email protected] 10 points 10 months ago (1 children)

Since I first saw a picture of the thing I thought it was ugly as hell. Last week I saw one in real life and I have to say, it's even uglier than I thought it was. And it really looks like it could have been an '80s era crappy kit car for a full size truck chassis. I mean, strikingly ugly and stupid looking. Embarrassingly so.

[–] Mog_fanatic 6 points 10 months ago

I've seen a few now and every time I can't help but think that it's like what a 4 year old with a marker and paper trying to draw a truck from memory would look like in real life.

[–] Gazumi 13 points 10 months ago

Just as with the battery issues, owners will be out with warranty for driving in the rain

Can someone share some information on the actual steel they use? This linkedin thread says they use 301, someone in this thread says they use a proprietary steel? (Can someone share the chemical analysis in this case?)

They should have went with weathering steel instead, and just leaned into it. This is literally Delorean all over again. Beginning to think Musk microchipped his own brain.
