Rust on a 2019 M3

Big-Cap558 | 2025-10-06 16:29 | 215 views

Thought you guys would appreciate this 2019 model 3 I saw at a dealer. 10 000 km. Rust behind front wheels. Looks like a 1999 Opel with 100 000 km underneath. Tried posting in another Tesla sub but was immediately removed from there.

100 000 km, not 10 000* Roughly 60 000 miles

Bulky_Specialist9645 2025-10-06 16:37

Gee, apparently all that extreme cold weather testing they did in southern California didn't reveal these faults....

Big-Cap558 2025-10-06 16:44

Meanwhile this 60 USD, 400 000 km or 250 000 miles Volvo V70 from 1997 is free from rust underneath: https://www.blocket.se/annons/1402395186

I can find some Opels in 100000 kms on clock but still in mint condition

Sirio2 2025-10-06 16:52

I read the title and thought it was crazy for a 2019 BMW to have rust…

Arthur2_shedsJackson 2025-10-06 16:53

I just read the title without seeing the name of the sub and was wondering what the hell are BMW doing? Makes a lot more sense now lol.

Zippytang 2025-10-06 17:11

The metal prep and painting wasn’t done correctly

S3er0i9ng0 2025-10-06 17:15

Wow the other subreddit just removes anything negative? Is Elon the mod there or something?

Big-Cap558 2025-10-06 17:17

Bot flags anything critical for mod review and then it disappears, it seems

S3er0i9ng0 2025-10-06 17:28

That’s wild! No wonder I only see people saying how great their car is and how awesome fsd is on there lol.

laser14344 2025-10-06 17:31

Tesla stans have no respect that there is already a car called the M3 then demand respect from car guys.

garbageemail222 2025-10-06 17:33

I'm getting this fixed on my Model 3 right now. It's a dumb design fuck up, most cars have plastic trim around the wheel wells to protect the metal from debris kicked up by the tires. Model 3 is just metal to the edge. I'm waiting for a class action to join, this is a clear defect in engineering.

[deleted] 2025-10-06 17:34

Shocker! \s

Big-Cap558 2025-10-06 17:36

Yes. The fix will just delay the inevitable

meshreplacer 2025-10-06 17:45

Did you not park it in the Garage? Warranty is void if you do not follow the requirements.

S3er0i9ng0 2025-10-06 17:51

I think the metal wasn’t treated properly. It shouldn’t rust this quickly. The plastic pieces are mostly for show and to make cars look more off-road ready. Cars have been made out of metal to the edge forever and haven’t had these issues. I wonder if it’s a wide spread issue or if it’s a one off.

Im_Orange_Joe 2025-10-06 17:58

Yeah no rational car enthusiast would ever call a Model 3 an “M3.”

Engunnear 2025-10-06 18:03

But see - Sandy Munro creams in his pants over Tesla saving $5 per vehicle. Never mind the design drawbacks…

StellarJayZ 2025-10-06 18:06

They have metal parts?

StellarJayZ 2025-10-06 18:07

They do it here all the time and I’m always confused.

Engunnear 2025-10-06 18:08

I’m guessing that you don’t remember when Tesla said they were going to produce x cars per year at Fremont, and people who could actually do math pointed out that they didn’t have the paint line capacity due to the cap on their allowable volatile organics emissions. Tesla went ahead and cut the paint to the absolute bare minimum required.  This is what they call “the chickens coming home to roost”.

S3er0i9ng0 2025-10-06 18:09

lol that guy is such a shill idk how anyone can take him srsly

jpharber 2025-10-06 18:12

It’s okay, they can fix that with an OTA update. /s

S3er0i9ng0 2025-10-06 18:13

Yah not surprised about that lol. I figured it was just them building garbage cars to make more money especially once they’re out of warranty which they made that happen more quickly with how distance is counted by the cars to avoid having to do repairs.

Big-Cap558 2025-10-06 18:14

Some shitty alloy it seems

za72 2025-10-06 18:16

two coats of paint.. a pebble will bounce off the road and chip the paint

asphaltbabe 2025-10-06 18:27

I didn’t think aluminum rusted?

RocketLabBeatsSpaceX 2025-10-06 18:42

Damn. The paint peels away and rusts underneath? I was two seconds away from arguing all cars get rusty frames, etc after a while but this seems egregious. Lol

AveragePegasus 2025-10-06 18:43

they are super protective of the brand image. Im banned from the other tesla subreddit and I never posted or commented there lol Probably because I did a post on cyberstuck subreddit

sheldonth 2025-10-06 18:59

Mine is worse. Only happened to black paint.

fusiondynamics 2025-10-06 19:02

What area/state is this?

vmspionage 2025-10-06 19:02

Thought the same... the BMW M3 is a legend, the model 3 is a forgettable joke

Im_Orange_Joe 2025-10-06 19:08

Because they wish their car was an engineering work of art.

EconomicMasterpiece 2025-10-06 19:42

That guy got paid $5 per vehicle to be overly enthusiastic about them.

Mr-Zappy 2025-10-06 19:43

Interestingly, Teslas have a 12-year warranty for body rust, but I think it needs to be worse than this. I’ve been looking into it because my 2021 is rusting where the lift gate hits the taillights… Here’s what the terms are: The Body Rust Limited Warranty covers rust perforation (hole through the vehicle’s body panel from the inside outward) resulting from a defect in material or workmanship. The Body Rust Limited Warranty covers your vehicle for 12 years and unlimited miles. Note: For vehicles purchased before February 1, 2019, there is no Body Rust Limited Warranty coverage.

> most cars have plastic trim around the wheel wells to protect the metal from debris kicked up by the tires Most cars have a good paint job.

nlaak 2025-10-06 19:48

> where the lift gate hits the taillights The lift gate... hits... the taillights? What? I mean, I knew their fit and finish is crap, but WTH.

Mr-Zappy 2025-10-06 20:14

It’s not supposed to, but mine does on one side.

MeThinksYes 2025-10-06 20:25

You can ask u/hakimthumb from the mod team over there.

vilette 2025-10-06 22:09

I have a car from 2000, not a single point of rust. But it was made in EU

TiredBrakes 2025-10-06 22:35

Of course not. That name is reserved for the Mazda3. /s

SpectrumWoes 2025-10-06 23:33

“Resulting from defect in material or workmanship” They can just claim you abused the car and the materials and workmanship were top quality

[deleted] 2025-10-07 00:21

What model year

[deleted] 2025-10-07 02:56

[removed]

Kooky-Bet-4553 2025-10-07 05:40

As expected, it's Tesla.

aftenbladet 2025-10-07 07:49

My 2019 with 145k km looks like this one. It started before warranty was out, but Tesla claimed it was due to external forces (cus Teslas are not made to be drivable it seems)

aftenbladet 2025-10-07 07:51

From the inside out.. thats the kicker here. It needs to rust from the inside to be covered.. lol

Adventurous_Term_514 2025-10-07 09:27

It’s always the same spot. Sand and gravel and such tends to build up in there and essentially hold onto the water. Because of that and the design of these cars, the water doesn’t drain properly and speeds up the rust.

Ok-Bill3318 2025-10-07 10:46

So Tesla hasn’t figured out galvanising yet

Ok-Bill3318 2025-10-07 10:47

Most proper cars since the 1990s galvanise the panels. My 16 year old Holden Ute spends its life outdoors and has zero rust

Quirky_Tradition_806 2025-10-07 15:00

Hey... Tesla is now a Texas company. Leave my city alone.

Whosez 2025-10-07 22:53

I read it the same way lol

ReportMany2628 2025-10-08 10:55

I drive the same model/year, piece of shit car.

nlaak 2025-10-08 12:28

>It’s not supposed to, but mine does on one side. I'm constantly amazed at what people are willing to accept for the tens of thousands of dollars they pay Tesla, especially considering these have been solved issues for *decades* in auto manufacturing. There's zero chance I'd be signing for a car with any such flaws.

Admirable-Sleep-4789 2025-10-08 12:53

Model 3*

Mr-Zappy 2025-10-08 15:07

It wasn’t initially apparent. Consumers shouldn’t have to check for that sort of stuff.

TiramisuAlreadyTaken 2025-10-08 17:22

Was there a vinyl wrap on or around the rusted parts? That could trap moisture

Snow4us 2025-10-08 21:04

What fix are you doing?

garbageemail222 2025-10-08 21:53

Grind, color match, blend, clear coat.

General-Bend1129 2025-10-09 08:43

Within spec

javlin_101 2025-10-09 10:59

I thought the body was made of aluminum? I don’t know why but I thought rust was not possible. Is it? I’ve never seen a rusty one irl

Big-Cap558 2025-10-09 11:18

Probably some shitty steel alloy in the frame too

Dude008 2025-10-09 16:13

S/X is all aluminum, 3/Y is mostly steel.

Dude008 2025-10-09 16:13

S/X is all aluminum.

[deleted] 2025-10-10 06:52

I thought it was a actual M3, a BMW, and went "what, no way", the say the sub; "oh, makes senses".

Repulsive-Royal-5952 2025-10-12 06:34

I had my 2021 model Y trunk replaced under warranty for far far less rust than this. Tesla has a 9 year unlimited mileage rust warranty.

Repulsive-Royal-5952 2025-10-12 06:36

I got my trunk replaced at zero cost my Tesla under their rust warranty. I showed them the rust, they booked a time to get it repaired and that was that.
