There are 1 owner-reported engine complaints for the 2025 Mazda CX-30in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I wondered if, after my first service visit on 11-12-25, the dealership put regular leaded gas instead of premium in it, because there was a noticeable difference in gas mileage and the engine started revving pretty high, in my opinion. It also seemed to have less power (which was my main reason foe thinking the wrong gas had been out in). And since then, it hasn't been the same.
