2021 Mazda 3 History Check

About the 2021 Mazda 3

The 2021 model year of the Mazda 3 sits in the BP generation, a small car (hatch + sedan) that was Australia's #25-best-selling new vehicle in 2024. Mazda 3 has been a small-car favourite for two decades — early BL examples are now 14+ years old and frequently appear at $3-8k where a PPSR check is mandatory. Verify finance and write-off status; older Mazda 3s are popular targets for rebuild-after-write-off due to readily available used parts.

2021-specific issues to verify

These reliability concerns affect Mazda 3 examples from this generation. Service history (verifiable via PPSR notation) is the critical purchase factor.

1. Skyactiv-G petrol: minor oil consumption (top up between services)
2. Auto transmission shudder on early Skyactiv (2014-2017)
3. Touchscreen click-wheel wear on BM/BN generations
4. Rear hatch (hatch variant) strut failure after 5+ years
