I was just watching the Scotty Kilmer video and he mentioned reliability issues with Mazda VVT. I had no idea at all that there was an issue with it? Is it an old issue that has been resolved? I have a 2017 Mazda 3 and this has me a bit concerned now. I keep my cars a long time and a good part of my decision to buy a M3 was the reliability aspect of a Japanese brand.
