2.5 NA Cracked Cylinder Head with Oil leaking...How common is this?

Ok after few years how are the people with CD in their Mazda. I read a lot and everyone scared from CD but no so many have real issues. Is still there someone with real problems because CD in last years? In 2019-2020 Mazda recall and update software to all CD engine. Is that recall solved the problem, any issues with the engine after update ?
Mine is 2019 with CD 70k miles and it is ok. Software is updated on Recall.

I purchased the last 2020 CX5 on the dealer lot in Dec. that year.
I'm at 50k miles. The CD is not noticeable when driving. No cracked
head.....yet. I do have a vibration at hi way speed. And radio cuts in
and out.
 
Reported mine to NHTSA already. It was a 2018 that developed the cracked head a year ago. Decided to get rid of it. Am looking for a used vehicle right now, but will not purchase any 2.5 Mazda from 2018-2021.
 
I just heard back from Mazda CC and they will only provide partial assistance. I will still have to pay ~$1800. I am going to dispute this with them. But very disappointing.

No, the issue I am dealing with is a crack cylinder head for CD for the NA engine.

What year is your cx-5 and how many miles? My brother bought a used '21 CX-5 sport with the 2.5 NA CD engine and about 19,000 miles on it in March. Has the remainer of powertrain warranty. So far, it's been reliable.

I have a '16 sport 2.5NA engine with around 92k miles. had gone to the Mazda dealer recently and asked about the cracked head issue with the current 2.5NA CD engines and they haven't seen any issues, but that issue has happened with the turbo engines he said. Just wanted to get an idea.

No real pattern. 30k or 80k.
 
I'm from Europe and last year buy Cx5 2019 fros USA it's 70k miles
Here this problem isn't popular, our cx5 is with CD too. Now found this forum and I'm little worry.
Hope everything be fine.
But statistics shows 300k+ cx5 sold in USA in 2018-2019 and think not so many reports for this problem under 100 official, maybe 1000_2000 unofficial. This is less then 1%

Just remember that people will be more vocal about the problems they are having. If there is no problem, there is nothing to complain about, and also no praise for working cars because they're doing their job. That's one of the reasons why the problem seems to be reported so much on social media and discussion boards like ours. People come looking for answers and/or information, or to find others dealing with similar issues so that they don't feel like they're going through it alone.

So I have started to see reports of cracked cylinder heads on CX5s (2018-2019) resulting in significant oil leaks. The cars have only ~25K miles on them!
What's this all about? How many here have had this happen? Time to sell our CX5 before it happens?

We bought a used 2018 and immediately noticed the smell not realizing what it was. Took it back and learned if the issue. This car has 56k on it. Non Mazda dealer really came through and repaired all for us free of cost

FYI, having worked at a Mazda dealer years ago, the warranty guys if they are savvy could have got it covered under some sort of warranty or goodwill which is why they had it taken care of for you. Chances are they didn't pay for it either.
