2019 Mazda Mazda3 — short-trip driving and oil-change intervals

Write down what you already tried. A second data point from another 2019 Mazda Mazda3 owner helps more than a generic diagnosis. Then you'll know the next fork. Learned this the expensive way on a previous car. Might be overthinking it, but I'd rather overthink than overspend.

Don't overfit one forum story to your car. If it still isn't clear on the 2019 Mazda Mazda3, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. That's the whole play. If the story changes I'll post the new data.

Owner notes beat generic advice here. On the 2019 Mazda Mazda3 in North Jersey, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “short-trip driving and oil-change intervals,” that was the fork that mattered for me. Learned this the expensive way on a previous car. Wrote this up on my lunch break.
