Just got diagnosed with cracked cylinder head. After looking on social media, it appears this is a thing for the model years 2018 and 2019. Bad casting? Anyway I believe this should be a voluntary recall to correct such a flawed engine. I bought this new from a Mazda dealership and kept it up to date with service only through the dealer. The 60 month/60,000 mile drive train warranty ran out last July. However I only have 50,000 miles on the car…babied.
