2018 MG ZS MOT pass rate and common faults
MOT tests in 2025, published 22 Jun 2026. DVSA publishes a new year each summer.
5,098 MG ZS cars first used in 2018 had an MOT in 2025, at about 7 years old, and 74.6% passed first time. That is below the 80.9% for all cars first used in 2018.
The year is when the car was first used, as on its V5C log book, not the model year.

Typical mileage
Recorded mileage at the MOT. A car well above this range has done more work than most; one far below is worth a closer look at its MOT history.
| Cars | Low | Typical | High |
|---|---|---|---|
| 5,098 | 33,700 | 46,000 miles | 60,100 |
