Damn are you less than a year out of your powetrain warranty?

I had the exact same issue. 2019 cx5 touring w preferred package. No turbo. Noticed a smoky smell when I was running my ac one day. Got home a few min later and popped the hood and there was a tinnnyyyy bit of smoke coming from the back left of the engine. Took to stealership and they said it was a cracked cylinder head. Completely covered under powertain, I paid a $100 deductible. They said it was a known issue, something during manufacturing.

They had my car for 6 weeks to do the repair, I got my car back with almost 100 extra miles on it 🤔🤨

Works great now though, haven’t had any issue with the engine since. I would bug the fuck out of them for some kind of goodwill repair or discount or something. 7k fucking sucks for a car that is just barely out of powertrain. Apparently this is a known issue that didn’t effect enough cars to warrant a recall. Call Mazda direct, fuck the dealership.

Had it on my 2019. Less than a year later I got a notice to bring my car in to disable deactivation thing
