NHTSA Complaint #11609668 — 2019 MAZDA CX-5

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 mentioned, my car leaks oil everyday, and I have to constantly put oil in just to keep it from burning up. It smokes really bad, but I cannot afford a new car or afford to pay over $3K to get this fixed, or don't understand why they won't fix it if they know it was poor design???
