2022 Mazda3 cylinder head crack at 62,000 miles

[RichmondVa]

Well the Mazda known faulty cracked cylinder head issue continues! Beware!

My meticulously maintained 2022 Mazda3 2.5 started dumping oil at 62000 miles and yes 2000 miles out of warranty it needs the head replaced. I’ve contacted Mazda for a goodwill repair because the dealer quoted over $4000 to fix it. We will see if they stand by the faulty product design.

I will update today when I hear back from them. It’s just terrible to still be paying on a 3 year old car and have this kind of major top end engine failure.

sorry to hear,is it turbo ,or does it have cylinder deactivation?

No to either. Just a 2.5 sedan. My wife has a 2019 Mazda3 premium and now I’m in fear it will happen to it as well. I hope Mazda will stand by the product because it’s an issue they’ve known about for a few years now. I also hope the replacement cylinder head is an upgrade and not a replacement with the same fault.

Are the valve stem seals defective?

Not that I’m aware of no oil lose between changes it just cracked above the exhaust manifold never over heated always ran good just know faulty engineering.
