        How this compares

        2018 Mazda Mazda3108
        Median 2018 model here (85 vehicles)281
        Median 2018 sedan here (22)176

        108 complaints is 2.6 times fewer than the median 2018 model on this site and 1.6 times fewer than the median 2018 sedan. Among the 4 Mazda3 model years here it ranks 3rd for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.
