Tesla Model Y owners have reported a total of 5,085 problems for their cars built in the 7 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 Tesla Model Y. The 2021 Tesla Model Y cars have the most problems reported (1,508 problems).
| Model Year | Number of Problems |
|---|---|
| 2026 Model Y | |
| 2025 Model Y | |
| 2024 Model Y | |
| 2023 Model Y | |
| 2022 Model Y | |
| 2021 Model Y | |
| 2020 Model Y |
The following chart shows the 29 most common problems for Tesla Model Y cars. The number one most common problem is related to the vehicle's forward collision avoidance (1,697 problems). The second most common problem is related to the vehicle's vehicle speed control (499 problems).
It would not be fair to compare the Tesla Model Y 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 Model Y 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 Tesla Model Y 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 Tesla Model Y is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
