Owner complaint summary

Cylinder Head has failed at 53,000 miles. Mazda has a technical service bulletin acknowledging that this is a common occurrence with this part. They have an extended warranty for the turbo engine but not for the standard engine. Looking through online forums, there are hundreds of not thousands of these issues for this model year and engine. Mazda has clearly acknowledged there is an issue and should repair these manufacturing defects that are not normal wear and tear items.

This is an owner complaint filed with NHTSA (ODI #11745274). It is not automatically an official recall, investigation outcome, or manufacturer admission unless the complaint text itself describes one.
