Ranked on pass rate the MG6 sits 463rd of 575 models in the data. MG as a brand averaged 80.9%, so this model runs 18.2 points behind its own brand. MG6 cars aged 6 to 10 years passed 64.5% of MOT tests in 2025; for examples aged 11 years and over that fell to 61.2%.
A pass rate is not a reliability score. The full MG6 MOT record has the pass rate by age, every common failure and how the MG6 compares with similar cars.
MG6 fuel types
Petrol was the most common fuel among MG6 cars tested in 2025. Diesel still made up 45% of tests.
Where the MG6 fails its MOT
Where MG6 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 rigid brake pipes excessively corroded (8.8%), headlamp aim projected beam image is obviously incorrect (4.7%) and position lamp not working (4.1%). See every common MG6 MOT failure.
These are DVSA failure records across every MG6 that failed, not a claim that every MG6 has these problems.
What should you check when buying a used MG6?
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. 30.8% of MG6 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. 21.6% of MG6 failure items.
3
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 18.2% of MG6 failure items.
4
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. 13.7% of MG6 failure items.
5
Noise, emissions and leaks
Listen for a blowing exhaust, watch for smoke on start-up and look under the car for oil or fluid leaks. 4.4% of MG6 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 MG6 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 MG6 FAQs
Is the MG6 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 a 62.7% first-time pass rate for the MG6 across 1,614 tests in 2025, below the 72.3% average for all cars.
Do older MG6 cars fail their MOT more often?
MG6 cars aged 6 to 10 years passed 64.5% of MOT tests in 2025; for examples aged 11 years and over that fell to 61.2%. 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 MG6?
On the car itself, start with the areas it most often fails on: lamps, reflectors and electrical equipment, brakes and suspension. 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 MG6'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.
