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.
Sorry, I would of responded 3 days ago but I got banned from posting and I’m not sure why lol
Yes, I haven’t had a single issue with the engine since. Just a little smoky smell for the first week or so that I was worried about. But there was no visible smoke and the smell went away completely. Just oil burning off the block I guess 🤷 Runs as good as ever now.
