MGF MOT pass rate and common problems
The MGF passed 66.9% of its initial MOT tests in 2025, 5.4 percentage points below the 72.3% UK average. The item testers recorded most often was rbt (sp) efficiency below requirements.

How the MGF compares
Initial MOT tests in 2025, retests excluded. A car that failed and was repaired at the test station counts as a fail.
80.9%
MG average
72.3%
UK average, all cars
The MGF runs 14 points behind the MG average. It is 9th of the 12 MG models in the data. The average MGF arrived at its test 25.8 years old with 64,616 miles recorded.
A pass rate records whether cars met the roadworthiness standard on test day. It is not a reliability score, and part of any gap reflects how old the tested cars were.
MGF MOT pass rate by age
The same 2025 tests split by the car's age at test.
| Age at test | Tests | Pass rate | vs UK average |
|---|---|---|---|
| 11 years and over | 5,318 | 66.9% | 5.4 pts below |
Every MGF tested in 2025 was aged 11 years and over, so there is no other age group to compare with. The UK average of 72.3% covers cars of every age, so compare like with like.
Where MGF failures cluster
Every failure item recorded on MGF cars in 2025, grouped into the DVSA's test areas.
Brakes and lamps, reflectors and electrical equipment together account for 40.2% of recorded failure items. These are recorded failures across the model, not faults every car has.
The 10 most common MGF MOT failures
Specific items recorded on MGF cars that failed their 2025 MOT, as a share of all recorded failure items.
Together these 10 items make up 33.4% of everything testers recorded against failed MGF cars. The rest is spread across many smaller items, and one failed test often records several at once.
What to look at on a MGF
The recorded failures above, grouped by area, biggest first.
1
Noise, emissions and leaks
Recorded most often: catalyst emissions carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits, catalyst emissions lambda reading after 2nd fast idle outside specified limits and catalyst emissions carbon monoxide content at idle exceeds manufacturer's specified limits. 10.6% of failure items.
2
Brakes
Recorded most often: rbt (sp) efficiency below requirements and service brake performance efficiency below requirements. 8.7% of failure items.
3
Suspension
Recorded most often: component mounting prescribed areas prescribed area excessively corroded significantly reducing structural strength and ball joint excessively worn. 5.9% of failure items.
4
Visibility
Recorded most often: wipers does not clear the windscreen effectively. 3.4% of failure items.
The car's own MOT history matters more than any model average. A free MOT history check shows whether a specific MGF has failed on these items before, or had them noted as advisories. Buying one? See the used MGF buying guide.

MGF MOT FAQs
What is the MGF MOT pass rate?
66.9% of MGF cars passed their initial MOT first time in 2025, from 5,318 tests. That is 5.4 percentage points below the 72.3% average for all cars, and ranks 407th of 575 models.
What does a MGF most commonly fail its MOT on?
The item testers recorded most often on MGF cars failing their 2025 MOT was rbt (sp) efficiency below requirements, on 5.4% of failure items. Next were catalyst emissions carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits (5%) and component mounting prescribed areas prescribed area excessively corroded significantly reducing structural strength (3.5%).
Which area causes the most MGF MOT failures?
Across every recorded failure item, the largest area was brakes at 20.8%, followed by lamps, reflectors and electrical equipment at 19.4%.
Does this mean every MGF has these problems?
No. These are the items testers recorded across every MGF that failed in 2025. They show where the model most often needs attention, not the condition of any individual car.

MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025: class 4 initial tests, retests excluded, with failure items from failed tests (advisories and minor defects excluded), licensed under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability.
