percentage points above average
Ranked on pass rate the ZS sits 169th of 575 models in the data. MG as a brand averaged 80.9%, so this model runs 1.3 points ahead of its own brand. MG ZS cars aged 3 to 5 years passed 83% of MOT tests in 2025; for examples aged 11 years and over that fell to 59.2%.
A pass rate is not a reliability score. The full MG ZS MOT record has the pass rate by age, every common failure and how the ZS compares with similar cars.
ZS fuel types
Petrol was the most common fuel among MG ZS cars tested in 2025. Diesel made up just 0.1% of tests.
Where the ZS fails its MOT
Where MG ZS cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were tread depth below requirements of 1.6mm (8.2%), brake pads less than 1.5 mm thick (6.3%) and headlamp not working on dipped beam (5.9%). See every common ZS MOT failure.
These are DVSA failure records across every MG ZS that failed, not a claim that every ZS has these problems.
What should you check when buying a used ZS?
The areas above, most common first, and what an MOT tester looks at in each.
1
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 24.6% of ZS failure items.
2
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 23.9% of ZS failure items.
3
Tyres
Check tread depth across the full width of every tyre (the legal minimum is 1.6mm), and look for cuts, bulges and uneven wear. 22.4% of ZS failure items.
4
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 10.9% of ZS failure items.
5
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 8.1% of ZS failure items.
None of this replaces the car's own record. Run a free MOT history check on the registration to see every test, advisory and recorded mileage for that car.
What the MOT record doesn't tell you
Knowing MG ZS failures cluster around lamps, reflectors and electrical equipment and brakes tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used MG ZS FAQs
Is the MG ZS reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is an 82.1% first-time pass rate for the MG ZS across 63,767 tests in 2025, above the 72.3% average for all cars.
Do older MG ZS cars fail their MOT more often?
MG ZS cars aged 3 to 5 years passed 83% of MOT tests in 2025; for examples aged 11 years and over that fell to 59.2%. On an older example, the car's own MOT history tells you more than the model average.
What should I check before buying a used MG ZS?
On the car itself, start with the areas it most often fails on: lamps, reflectors and electrical equipment, brakes and tyres. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check a MG ZS's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025 (class 4 initial tests, retests excluded), licensed under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability.
