2021 Toyota Prius reliability

Fail rate by area

Top failures

1. Tyre tread below 1.6mm 0.82%

   Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.

2. Rear fog lamp not working 0.48%

   A failed rear fog lamp reduces visibility in fog and leaves you less visible to following traffic, so repair it.

3. Position lamp not working 0.39%

   A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.

4. Anti-roll bar linkage dust cover unsealed 0.33%

   A damaged dust cover lets dirt into the linkage joint, speeding wear and possibly needing a future repair.

5. Registration plate lamp not working 0.3%

   A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.

6. Brake pads worn below 1.5mm 0.27%

   Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
