In June of 2026 I started to have an oil leak. Took it to a mechanic's shop who diagnosed it as a valve cover gasket, ran the car for another 2 months, oil leak did not stop, got worse, to the point where my oil light came on where the oil was low enough, then I took it to another mechanic, they diagnosed it as some sort of pressure sensor that has to do with the oil, they replaced that, then that still wasn't the case, it was leaking, and they diagnosed it as a cracked cylinder head. This has been an issue with Mazdas in the 2018 to 2022 range for the CX-5s, and Mazda knowingly has put in faulty parts and is not willing to extend the warranty on this because it's not a turbo, this is a clever work around to avoid paying for something that should not be going out at this point.  For this car being under 60,000 miles, been taking very good care of it, always had the oil changed, I feel that this is not fair for the customer to have to replace something on an engine that shouldn't be addressed for a very long time, if at all. I contacted Mazda corporate, they refused to do anything about it, I also contacted the Mazda dealership in my area, they contacted Mazda corporate and are not willing to cover this as well, my parents had a Mazda back in 2008 that had a similar problem. The only way this was resolved was going through Mazda corporate and writing a stern letter to their management team.  At this point I've basically lost the trust of this manufacturer. I spent 25,000 dollars on this car, and now I'm going to have to spend 7 to 8 thousand dollars to get this part replaced, and that this point in the car’s life, that is outrageous. I will not be purchasing from Mazda ever again, there is plenty of documentation on the internet about this problem, and that Mazda refuses to do anything about it.","products":[{"type":"Vehicle","productYear":"2019","productMake":"MAZDA","productModel":"CX-5","manufacturer":"Mazda Motor Corp."}]}]}
