Subaru Ascent owners have reported a total of 1,219 problems for their cars built in the 8 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 Subaru Ascent. The 2019 Subaru Ascent cars have the most problems reported (540 problems).
| Model Year | Number of Problems |
|---|---|
| 2026 Ascent | |
| 2025 Ascent | |
| 2024 Ascent | |
| 2023 Ascent | |
| 2022 Ascent | |
| 2021 Ascent | |
| 2020 Ascent | |
| 2019 Ascent |
The following chart shows the 26 most common problems for Subaru Ascent cars. The number one most common problem is related to the vehicle's electrical system (283 problems). The second most common problem is related to the vehicle's visibility (200 problems).
It would not be fair to compare the Subaru Ascent 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 Ascent 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 Subaru Ascent 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.
Another way to measure the reliability across the model years of the Subaru Ascent is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
