MG ZS MOT pass rate and common faults
MOT tests in 2025, published 22 Jun 2026. DVSA publishes a new year each summer.
62,709 MG ZS cars had an MOT in 2025 and 82.5% passed first time. That is below what cars of the same ages scored (86.3%).
Find the year your car was first registered below, then check the faults it is most likely to fail on.
Pass rate by year
Each year's first-time pass rate, with a tick for all cars first used that year. Years with fewer than 300 tests, and cars over 20 years old, are left out. Years with 1,000 or more tests link to a page of their own, with that year's common faults.
Common failures
The share of all MG ZS cars tested that failed on, or had fixed at the station, each item. Worth checking before the MOT or before you buy.
| Item | Value |
|---|---|
| Tread depth: tread depth below requirements of 1.6mm | 2.0% |
| Headlamp: not working on dipped beam | 1.8% |
| Brake pads: less than 1.5 mm thick | 1.8% |
| Condition: has a cut in excess of the requirements deep enough to reach the ply or cords | 1.6% |
| Coil spring: fractured or broken | 1.4% |

Common advisories
Advisories are things the tester noticed that were not bad enough to fail. They often turn into failures later. What advisories mean for the next MOT.
| Item | Value |
|---|---|
| Tread depth: worn close to legal limit/worn on edge | 16.6% |
| Brake discs: worn, pitted or scored, but not seriously weakened | 16.4% |
| Brake pads: wearing thin | 7.4% |
| Condition: slightly damaged/cracking or perishing | 6.9% |
| Child Seat fitted not allowing full inspection of adult belt | 3.9% |
| Nail in tyre | 3.1% |
| Condition: has a cut but not deep enough to reach the ply or cords | 2.2% |
| Service brake performance: binding but not excessively | 1.8% |

Typical mileage
Recorded mileage at the MOT. A car well above the range for its age has done more work than most; one far below is worth a closer look at its MOT history.
| Age | Low | Typical | High | All cars, typical |
|---|---|---|---|---|
| 3-5 years | 19,800 | 28,200 miles | 38,800 | 30,900 |
| 6-8 years | 30,700 | 41,800 miles | 55,000 | 51,800 |
