We're very impressed with Mazda as a company – they compete with more upmarket brands on standard features and design, but they also stand out as safe, reliable cars too.

Mazda 3 Fastback reliability

The previous Mazda3 was rated highly in our 2019 Driver Power owner satisfaction survey, despite 17.5% of owners reporting at least one fault during the first year of ownership. The Mazda3 finished 43rd overall out of 100 cars surveyed - although we’d expect the new version to finish higher in next year’s survey.

On the whole, Mazda did very well. In our manufacturers list, the Japanese brand came fourth out of 30, with everything except practicality impressing owners.


The Mazda3 also scored well in the Euro NCAP crash test in 2019, earning five stars out of five. It’s fitted with a system named Smart City Brake Support, which will automatically apply emergency braking if a hazard is detected in the path of the car. The Fastback wasn’t tested but the same technology and structures are lifted from the hatchback.

All the other safety equipment that you’d expect, like anti-lock brakes, electronic stability control and a full suite of airbags are fitted, as well as normal driver aids such as traction control. There’s also a hill-start assist feature which holds the car on the brakes when you’re pulling away on an incline.
