NHTSA Complaint #11495062 — 2017 MAZDA CX-9

This problem has been documented and know by Mazda for awhile. They are aware that their 2.5 Turbo liter engine has the problem of cracking the cylinder head due to some overweight of the same engine component. My Mazda local dealer already inspected the car and told me that the fix is replacing the whole cylinder head, which with them would cost me 3.5k. My warranty company, which I purchased when buying this used car, didn’t took responsibility of the repair cost because it was pre existing condition before I bought the car. Many people over the internet have reported this same issue happening to them, models year between 2016-2019. This issue cause a leaking of coolant. Which in my case has been a lot built up, to the point that you can grab it with your hands (the coolant residual).
