Highly doubt Ford is involved this time. They've long broken up. I believe the engineering from the ground up is pure Mazda.
The drivetrain is shared with the CX-5 mostly as-is.

I believe the CX-9 is the debut platform for the 2.5T and there were reports of cracking cylinder heads and coolant loss(also affected the 6 and CX-5) purportedly addressed in 2021 with a revised cylinder head.

There was also Oil consumption issues mostly with 2021 USA MY models due to defective valve stem seals.
