2.5L NA Cracked Cylinder Head with Oil Leaking

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.

I have 2019 Mazda CX-5 sport, non-turbo (naturally aspirated). I do not know if my SUV has cylinder deactivation. If there is, it is not noticable. I bought it new and I have put 110k miles on it. So far, no problem whatsoever. Even my brake pads are the original that came with car it had never seen the repair shop. I changeed the oil myself every 5k miles. I changed the air filter every 36 k miles. I have changed the spark plugs at 75k. Running great. Changed the tires at 70k miles.

I would say that is the most typical Mazda ownership experience, IMHO.

The easiest way to tell if your car has CD is to look at the 8th digit in the VIN. If it is 'M', then it has CD. If it is 'L', then it does not.
 
I've just run across this forum and wanted to add my two cents. In this case it was more like $5000.00. Towards the end of November, I too started having a burning oil smell in the passenger compartment. This was for my 2018 CX-5. I brought the car in to my repair shop and they diagnosed it right away as a leaking cylinder head. The car didn't quite have 70K miles on it at the time. The nearest Mazda dealer is 45 minutes from me and I was not about to drive that distance with noxious fumes, so my trust auto repair shop would take care of the repairs. The sent the cylinder head to a machine shop actually close to the Mazda dealership. Before they flattened the head, they did a pressure test and discovered that the cylinder head was flawed at the time of casting the part. So my $4000 repair jumped up to $5000. The repair shop found no recalls, but I went ahead with the repairs. I received my vehicle back on December 11. And then started my phone calls to Mazda.

In all I made 16 phone calls to Mazda, later on adding emails with detailed information about my case. All the customer service reps started with the same song and dance about not using the Mazda dealer repair shop. My argument was two-fold: 1) did they want me to risk my health inhaling those dangerous fumes, and 2) the same machine shop the Mazda dealer would have used determined that that part was incorrectly cast, so it wouldn't matter who did the repairs. The faulty part was the faulty part

Eventually the case was bumped up to a case manager, who took a number of weeks to finally get back to me after multiple calls. I should add that I started keeping a detailed log on a Word document, of who I spoke to, the date, the time, and what was said. This proved invaluable. At the end of January the case manager said that she did not think Mazda would be able to help due to the lack of dealer issue again. I went through my case once more, hitting on those two points above. We were speaking on the phone at this point. She told me she would check with her higher ups to see if they could do anything. Imagine my surprise when later that day I received a call from the case manager telling me that they would cover half of the cost of repair, so $2500. I was thrilled. The car was out of warranty, and yes, this is their fault, but I never really thought they would come through. The check arrived yesterday.

As I told nearly everyone I spoke with, I was never nasty, never cursed, and was very patient. I think that paid off. As did my detailed log that I sent to the case manager.

Mazda really should do a full recall on this issue, but I'm happy to have gotten something out of them.

I recently had a similar experience with Mazda Canada for an unrelated, out-of-warranty drivetrain issue on my 2018 CX-9. Initial denial and lots of pushback since my vehicle was out of warranty and never serviced at a dealer, but I continued to plead my case without being overly aggressive or demanding. In the end, a Mazda dealership performed the repair using brand new OEM parts, and Mazda Canada covered almost half of my repair bill. The whole process did take almost 3 months from start to finish, but once the management team got involved, everything moved a lot quicker.
