We cover the Mazda3 across the BK, BL, BM/BN and BP generations. Engines include 2.0- and 2.3-liter MZR units, the Mazdaspeed3 2.3 turbo, 2.0- and 2.5-liter Skyactiv-G and the 2.5-liter turbo, with Skyactiv transmissions and i-Activ AWD.



Your 2019 Mazda 3 is from the fourth-generation Mazda3 (BP), which covers model years 2019–2026. It is the first model year of this generation: the platform, wiring and many procedures changed compared with the previous model, so a manual for an earlier year will not match it.
Check the model year on your VIN: on a 2019 vehicle the 10th character of the 17-digit VIN is “K”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 7 years old, a 2019 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.
Same generation: 2020 Mazda 3, 2021 Mazda 3.
