If the bolts were overtorqued, it's too late as the damage been done and on those overtorqued will have unseen micro-cracks in the cylinder head. Just a matter of time before micro-cracks subjected to hot pressurized engine expand and continually become worse.If it's a bolt torque issue, would be nice if they issued a recall to have the bolts checked and re-torqued correctly, it that is possible.
Just a waiting game. They'll fix the ones that fail during warranty period. Anyone else is out of Luck.
It might be worth it to pay for a specialized test (by a third party) to verify micro-cracks in cylinder head before the warranty expiration and then request Mazda fix it. I am considering having this specialized testing before the warranty expires.
Edit: maybe in the future the governments can mandate engines go though spot check engine testing for micro-cracks. Especially since vehicles are high priced items.
