Blow head gasket on a 2019 cx-5.
Hello,
I'm posting to see if there is anyone else out there that has had the head cylinder and head gasket go in their cx-5. I have an 18 month old cx-5 that now has this issue after 40,000 Kilometers /25,000 Miles. No check engine or any other light illuminated on the console prior to this happening. I had just gotten an oil change 2 days previous and the first sign something was wrong was a strong burning smell coming from the engine. When I arrived home I saw that oil had leaked in my garage, on my driveway and left a trail down my street. Smoke also came from under the hood.
The Mazda dealership I bought and had the car serviced at tells me that Mazda is aware of some vehicles having an issues with defective head cylinders and that some VIN numbers are effected.
I am now faced with owning a vehicle that is 1.5 years old and will have a rebuilt engine being put together in a dealerships service department. Has any other cx-5 owner had this issue? I have the 2.5L non-turbo.

I live in Southern California, and own a 2019 CX5. I just took it in yesterday because my wife was complaining about a burning smell. We had just changed the oil as well. And have always brought my car in to Mazda to be serviced. I removed the engine cover and noticed that there was oil leaking out of the head gasket. I brought it in and After inspection they told me I needed a new head cylinder. I asked what the cause was but the service rep couldn't respond as to why. So I searched Google to see what I found and came across this forum. I guess it may be more common than I thought. My car only has 31k miles. Always had mazda change my oil fully synthetic. Idk maybe just a faulty part. Hopefully not ongoing once I'm out of warranty.

This just happened to us -- 2018 Mazda CX5 Touring with 46,000 miles, purchased new.
Dealer said it could be 4-6 weeks before they can get parts. No loaner available at this time, but will call with next one is available.
We also bought a new 2011 CX9 and still own it. This is the first mechanical issue with either car.

Just thought I’d add an update to our situation. We got the car back from the dealer who replaced the cylinder head on November 27th and we have had absolutely no problems in the two months since. Keeping my fingers crossed.

Burning smell, oil seen on ground. Checked oil down 1 quart. Filled it backup checked it again ok, drove it to dealer five miles. The checked it the oil down half a quart they said. Knew exactly what the issue was completely covered. They are replacing the head, no engine light no low oil nothing, no codes either I check myself. Only 16k miles on the car. Hopefully they fix it right? I have another CX-5 with 255k miles with no oil leaks at all!!
