Tesla MOT pass rates
Tesla’s first-time fail rate across 4 models was 14.8%, better than the national 22.6%. The spread between models below is the interesting part.
| Model | Tests | Pass rate | Fail rate | Median miles |
|---|---|---|---|---|
| Model 3 | 80,084 | 85.7% | 14.3% | 46,522 |
| Model Y | 31,485 | 85.8% | 14.2% | 33,458 |
| Model S | 10,073 | 81.5% | 18.5% | 81,837 |
| Model X | 5,746 | 80.4% | 19.6% | 61,506 |
Fail rates are first attempts at class 4 normal tests in 2025, from DVSA’s anonymised data (retrieved 2026-09-12). Age mix drives a lot of the spread: a model sold mostly since 2020 will beat one whose survivors average 15 years old. Each model page shows the rate by age band.
