Applicable to 2018-2020 Mazda6 GT Reserve and Signature trims (refer to VIN range).
 
"To eliminate this concern, the design of the exhaust manifold gasket and the cylinder head has been modified to reduce the force on the cylinder head" - from TSB.

Hopefully newer 2.5T should be free of this issue. Fingers crossed. :unsure:
