Gen3 - Rust already...?

[Cyclic]

So I was browsing the other Mazda3 forums and came across a thread about rust found between the trunk liner and the rear window. Looks like there are quite a few people who are having the same problems so I went outside to take a look at my car and there it is... rust forming on my 8 months old car... Seems to be an issue for the sedans only. I'd recommend Gen3 owners go and check their cars. I already called the dealer and bringing it in later in the afternoon. Took some quick pics at work but the quality isn't the best as it was sunny out and couldn't tell if they were good or not until I went back in.

Mazda at it again.. Sorry to hear, hope it gets sorted..

[thirdgen3]

I had rust showing up on mine too...different spot though. Mine were on the spot welds near the license plate lights. I noticed them when I had the trunk open one day. Took it into the dealer and they applied some paint over it to "seal" it and told me to keep an eye on it....

I'll upload pictures later tonight. Anyone else have this issue?

[20143GTowner]

not the license plate lights, but I just opened my trunk and found little circles of rust between the trunk liner and rear window just like @Cyclic . Really not to happy about it tbh. Going to have a talk with the guys up front as soon as I can.

@Cyclic I just looked at mine and I also have it on the rear trunk/rear window area on every weld point...what dealership did you go to? I'm going to notify the dealer I go to regularly about this. As mentioned before I went to Dave Wood (Now called New Roads) in Newmarket...but let's just say I won't be returning there for numerous complications with service there and damage to my car...long story. That could be a whole other thread with pictures! I'll notify Avante about this when I'm there next...Newmarket saw the rust near my plate lights and just put paint over it and told me to "monitor" it. Anyways pictures of my rust below. RUST GTFO.




Here's the pictures from the rust I mentioned in my earlier post on my car.

I just found some on the same spot, @Cyclic. But mine is a gen 2.

[Cyclic]

Yeah, the rust is appearing at the welds. Just got back from the shop now. They took pictures and will send it to Mazda. They told me it will take a week to hear back from them.

Wow 3rd gen rusting already not good. Mazda didn't change

[Captain Mazda]

Wow 3rd gen rusting already not good. Mazda didn't change

Not surprising, considering how cheap the 3rd gen build is.

[Cyclic]

Updated first post with better pics. No signs of it at the welds near my license plate lights either. Good ole Mazda. In Rust We Trust...

[20143GTowner]

correction, I do have rust above my license plate, kinda smack in the middle beneath the lights.

SOB

wow this is unbelievable, I just bought my 2015 Mazda 3 last month... there's no way to prevent this from happening? I wonder what the dealership will do about this

[20143GTowner]

heres some photos:





and I also found some in the engine bay, below my cold air intake:

Just wondering if all these cars that have rusting are the GT models and were they made/imported from Japan?

so far its looking like the cars from Japan are the ones with the issues. Iv checked a couple GS and GX models from Mexico and there was no signs of rust anywhere

Wow.. just our luck eh? You would have thought the ones from Japan wouldn't have the issue...

I guess the only way would be to keep it parked in garage and dry it off after every rain fall lol

Mine's a GT from Japan but I don't think there's relevance here. Doesn't Japan also have cold winters with snow? My car was not driven at all this whole winter but parked outside. 7800km after 8 months. @20143GTowner man you're in worse shape than I am but I haven't looked in the engine bay yet. We'll see what Mazda has to say... Maybe I made the wrong choice over the BRZ/WRX lol

[tweak_s]

Seconded on whoever said rust proof, it does help.

But holy moly, that is SOON. I didn't have it on my gen 1 until about 3 years later.

I really hoped Mazda had changed.

[Jon_g86]

Luck has it... I too have a Japanese built 3 (only the GT is assembled there so I'm told) which has identical rust issues as to what's being posted. There's brake dust rust or rail dust rust alllll over the body but the trunk itself holy shit.

A bunch of rust spots above and around the license plate which are actually bubbling.

Also have rust around the trunk seal as well.
Mines a 2017 Mazda3 GT beginning with JM1BN1W33H...

Have pics but not sure how to post them from my phone.

I'm in the same boat. Area beside the rear-view camera is rusting. After so many years, they can't make a car that does not rust after a year?
How do they not improve on their manufacturing process (w/ respect to rusting) after decades. My 2006 didn't rust like this.

Did they send the factory back through time?

Jesus how cheap are these cars. That's pathetic. I'm starting to think I should have gone with the Golf.
This car better drive amazingly. I'm already missing my bmw.

Rust proof your car ever year it does wonders

Krowning it?

[devoncsmith16]

Krowning it?

Yes but I prefer rust proof it creeps really good and u can get it pretty much in any area that u need

[Cyclic]

My car was rust proofed a month after getting it with Corrosion Free so that's probably why I don't see rust anywhere else. Not like they are gonna spray it onto your paint to prevent what's happening here...
