Mazda MAZDA2 owners have reported a total of 34 problems for their cars built in the 4 model years listed in the chart below. The chart shows the number of problems reported across all service years for each given model year of the Mazda MAZDA2. The 2011 Mazda MAZDA2 cars have the most problems reported (12 problems).
The following chart shows the 15 most common problems for Mazda MAZDA2 cars. The number one most common problem is related to the vehicle's steering (11 problems). The second most common problem is related to the vehicle's air bags (4 problems).
It would not be fair to compare the Mazda MAZDA2 of an older model year to newer model years since older vehicles have been in service longer and thus are expected to have more problems. In order to compare the reliability across MAZDA2 model years, we use the PPMY index which is defined as the problems reported per thousand vehicles per Year. A smaller PPMY index indicates greater reliability of the given model year cars.
PPMY = P / S / Y * 1000,
where P = total problems reported during the life of a Mazda MAZDA2 model year; S = total units sold of the model year; Y = years since the debut of the model year (the age of the vehicle).
The results are shown in Table 3.
