Dealer just called and said my head is cracked and will be replaced under warranty.
Cylinder head ended up cracked and needing replaced for $4500.
Had the cylinder head crack on my 2020 Mazda6 2.5T at 50k miles back in 2023 which caused coolant to leak and overheat my vehicle.
after 2.5 months, my CX-9 is back from the shop with a new cylinder head!
