Ford Focus owners have reported a total of 26,703 problems for their cars built in the 20 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 Ford Focus. The 2012 Ford Focus cars have the most problems reported (4,889 problems).
The following chart shows the 31 most common problems for Ford Focus cars. The number one most common problem is related to the vehicle's power train (6,359 problems). The second most common problem is related to the vehicle's electrical system (4,236 problems).
It would not be fair to compare the Ford Focus 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 Focus 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 Ford Focus 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.
