Actually, the number recalled was >260,000.
IF this is accurate [and that's a big if], Mazda is in way deep trouble.
I can't imagine the number is anywhere near 50,000. But it's concerning that at least 3 low-mileage 2018 CX-5s all suffered the exact same engine oil leak, resulting in an engine replacement by the dealer, within a week of each other. The odds of that happening from random chance, as opposed to a broader issue, have to be pretty low, right? Maybe a bad batch of gaskets or something.
