2022 Mazda CX-5

Cylinder head cracked resulting in engine overheating with code P111A. Gasket bolts expelled due to excessive heat and pressure. Evidence of coolant spray along hose connections, lower cover and transfer case. Smoke came out of the engine compartment first followed by warnings titled 'Critical vehicle malfunction alert' 'pull over immediately' Check engine light came up shortly thereafter. Vehicle inspected by an authorized Mazda service center, confirming the engine overheat code. This is the statement from the service representative: 'Mazda wants to start with a cylinder head prior to doing an engine'. The technician's analysis indicates they received warranty approval for Entire cylinder head and head gasket replacement and all associated parts. No warning lights prior to the failure. They started just as the engine started smoking. Potentially related information: The vehicle displayed error code for a coolant valve issue 3 weeks before this issue for which a TSB already existed and Mazda replaced the part. TSB related to cylinder head defect exists for model year 2019, but not for model year 2022.

Cracked cylinder head, August 2023. I'm not sure if it's a safety hazard, but it seems that oil being sprayed around a hot engine could be a fire hazard. Also, since the oil light comes on with no warning, it could cause people to have to pull over on a busy interstate because you shouldn't drive with the oil light on. I had almost 14,000 miles on my 2022 Mazda CX-5 when the low engine oil light came on. I had recently had an oil change done, so the oil should not have been low. I put oil in it and drove it to the dealership. They discovered oil sprayed everywhere in the engine compartment, and discovered the cracked cylinder head. It is a known problem. The car was still under warranty so they replaced the cylinder head. There have been no changes or improvements to the cylinder head, so theoretically the replacement cylinder head could also eventually crack.

The vehicle unexpectedly caught fire and the results could have been catastrophic. Almost new car under warranty. All details are in the uploaded PDF letter and photos. I have contacted Mazda and they claim they do not investigate, only insurance company will investigate. My insurance company will pay me for the total loss but does not plan to investigate. I think this is dangerous and unconscionable. Thank you for any help or guidance.

When driving in the wind at speeds greater than 50mph , there is an extremely loud high pitched reedy noise. I have many videos of this and Mazda won’t address it/says it’s not an issue. I travel for work in SD, a very windy state, and often listen to this sound 2+ hours straight and can’t hear any music/phone calls/audiobooks over the noise. It is dangerous because I can’t hear anything but this, and it causes a lot of stress/anxiety/overstimulation. I wish I never bought this vehicle.

My 2022 CX5 sunroof exploded while driving on highway, glass fragments were caught by the shade so no one was injured thankfully. But this could have easily caused bodily injuries if the shade was open. The loud explosion and glass fragments could have distracted/impair the driver, leading to a serious incident. I do not suspect it is caused by impacts from debris since there was no large vehicles around me at the time of explosion and no other impact noise was heard at the same time. There are other similar incidents regarding sunroof explosion that were posted online.

I was driving down the highway and heard a loud bang, sounded like a gun had gone off. I looked at my windshield thinking maybe something hit, but nothing shot back at me and there was nothing on my windshield. I took a look at my back windshield and it was completely fine so I was under the impression maybe I ran something over, but about 45 seconds later i heard the airflow coming from the top of my car. I uncovered my sunroof shade and it is completely shattered. I took it up to my dealership and they are declining to cover the damages according to my car manufacturer. This has happened to multiple people who have the same make and model vehicle as me as there is a forum website for my exact vehicle, and others who have had this happen to them have reported it to their manufacturers as well.
