   My 2019 Mazda CX-5 (equipped with the 2.5L naturally aspirated SkyActiv-G engine with cylinder deactivation) has experienced a severe structural failure resulting in a cracked engine cylinder head. This casting defect allows pressurized motor oil to leak continuously from the cylinder head down onto the hot engine block and nearby exhaust components. This has led to the following severe safety risks: engine oil is leaking onto the exhaust manifold and creates an extreme risk…

   My fuel pump burned out after only 60k miles.... very expensive repair. Mazda said the problem was only with the early 2019 models so mine wasn't included yet my fuel pump did exactly what the ones included in the recall did, but I was left with over $1700 repair bill to replace the fuel pump. Obviously the "improved design" used in the second half of the year isn't really improved, and I've never had to replace a fuel pump on a vehicle with so few miles on it. We were…

   Drove 39 miles, around ~55 minutes. Parked the car, realized that I parked a little too far from the spot, car just stalled while rolling. Pressed accelerator, nothing. Turned off the car, tried to start again, it cranked but didn't start. Had to tow it to the nearest mechanic (total of ~2 hrs until my car got picked up and dropped off), mechanic calls me and tells me my car started fine. I'm thinking it could be 5321K recall but not sure as my VIN is not in the recall nor…

   I have a 2019 CX5 Mazda that consistently leaks oil and smokes. After taking it to a mechanic, I learned that this is a known Mazda issue, but because my car is under warranty, they won't help me. The Cylinder head is pours, and my mechanic said even if he replaces it, it will happen again due to the design. After I have checked online, it seems that MANY people have this issue from 2018-2021. Mazda even made TSB #SA-031-21 to cover some of this issue but no recall. As…
