2025 MOT results
Hyundai Coupe common problems
The most common reason a Hyundai Coupe fails its MOT is a weak handbrake, on 26.1% of its 2,312 failed tests in 2025. Against other cars of the same age, 7 faults stand out, the widest gaps being: a steering fault at 8.5% of failures against 1.2% expected; a weak handbrake at 8.0% of failures against 1.6% expected; a lighting fault at 8.4% of failures against 2.2% expected.
- Tests in 2025 4,862 Cars aged three and over
- Failed first time 47.6% 2,312 tests
- Found a dangerous defect 14.4% Unsafe to drive away
- Ended with an advisory 73.2% A problem to watch, not a failure
What fails a Hyundai Coupe MOT
Each bar is the share of failed Hyundai Coupe tests with that defect. Where we can compare it with cars of the same registration years, the marker shows what an average car of those ages records (12 of the 12 items below).
Most common reasons for failure
A test can fail for more than one defect, so shares add up to more than 100%.
| Defect | Share of failed tests |
|---|---|
| Parking brake efficiency below requirements Brakes | 26.1% |
| Position lamp: not working Lamps, reflectors and electrical equipment | 14.4% |
| Exhaust system: major leak of exhaust gases Body, chassis, structure | 12.2% |
| Catalyst emissions: lambda reading after 2nd fast idle outside specified limits Noise, emissions and leaks | 9.3% |
| Steering rack: gaiter missing or no longer prevents the ingress of dirt Steering | 8.5% |
| Anti-lock braking system: warning lamp indicates an ABS fault Brakes | 8.4% |
| Service brake performance: excessively binding Brakes | 8.2% |
| Parking brake efficiency less than 50% of the required value Brakes | 8.0% |
| Wipers: does not clear the windscreen effectively Visibility | 7.5% |
| Headlamp aim: projected beam image is obviously incorrect Lamps, reflectors and electrical equipment | 7.4% |
| Parking brake performance: inoperative on one side Brakes | 7.3% |
| Malfunction indicator lamp: inoperative or indicates a malfunction Noise, emissions and leaks | 6.7% |

Weak handbrake
26.1% of failures 6.2% expected 4.2 times as often
The handbrake cannot hold the car to the efficiency the test requires, usually from a stretched cable or seized rear callipers.
On a hill, the handbrake should hold the car with a couple of clicks left in the lever.
-
Sidelight out
14.4% of failures 13.6% expected about as expected
A sidelight, also called a position lamp, not working. It marks the width of the car at night.
Walk round the car with the lights on and the hazards going; these are the cheapest failures to avoid.
-
Exhaust leak
12.2% of failures 4.3% expected 2.8 times as often
A hole or split letting exhaust gas out before the tailpipe.
A blowing or rasping note under load, loudest from cold.
-
Emissions above the limit
9.3% of failures 3.4% expected 2.7 times as often
The exhaust gases are outside the limits for the car, which can be the catalytic converter, a sensor, or simply a poor state of tune.
A long run before the test helps a catalyst get hot; a persistent failure usually needs a diagnosis.
-
Steering fault
8.5% of failures 1.2% expected 7.1 times as often
A fault in the steering: play, damage, or a component that no longer works as it should.
-
Lighting fault
8.4% of failures 2.2% expected 3.8 times as often
A lighting fault. Lamps are the most common failure area on almost every model, and the cheapest to put right.
Which parts of the car fail
Brakes is the area that most often fails a Hyundai Coupe, on 54.9% of failed tests. That is also where it differs most from cars of the same registration years, which record 26.4%.

| Suspension | 31.7% |
| Noise, emissions and leaks | 22.8% |
| Body, chassis, structure | 20.2% |
| Visibility | 17.1% |
| Steering | 15.9% |
| Tyres | 15.4% |

What testers warn about
73.2% of Hyundai Coupe tests ended with at least one advisory: a fault the tester found that did not fail the test. On Hyundai Coupes, these are the items to ask about on a car you are viewing, because they are what the last tester expected to go next.
Most common advisories
Share of all tests, passes included.
| Advisory | Share of tests |
|---|---|
| Tread depth: worn close to legal limit or worn on edge Tyres | 18.0% |
| Rigid brake pipes: corroded, covered in grease or other material Brakes | 15.3% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 14.7% |
| Sub-frame: corroded but not seriously weakened Suspension | 11.9% |
| Exhaust system: minor leak of exhaust gases Body, chassis, structure | 11.6% |
| Tyres: slightly damaged or cracking or perishing Tyres | 10.8% |
| Brake pads: wearing thin Brakes | 9.5% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 9.1% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 7.5% |
| Registration plates: deteriorated but not likely to be misread Identification of the vehicle | 7.2% |
| Coil spring: corroded Suspension | 6.5% |
| Service brake performance: binding but not excessively Brakes | 6.2% |

Hyundai Coupe problems: common questions
What is the most common problem with a Hyundai Coupe?
Of the faults that fail an MOT, “Parking brake efficiency below requirements” is the most common: it appears on 26.1% of failed Hyundai Coupe tests. Across categories, brakes is the area that most often fails one, on 54.9% of failed tests.
How often does a Hyundai Coupe fail its MOT?
47.6% of Hyundai Coupe tests in 2025 were not passed first time, from 4,862 tests of cars aged three and over. Allowing for the age and mileage of the cars tested, that gives it a UK Motoring Reliability Score of 36 out of 100, where 50 is as expected.
Does anything fail more often on a Hyundai Coupe than on other cars?
Yes. “Steering rack: gaiter missing or no longer prevents the ingress of dirt” appears on 8.5% of its failures against 1.2% for cars of the same age, and “Parking brake efficiency less than 50% of the required value” appears on 8.0% of its failures against 1.6% for cars of the same age. Where an item is missing from the national figures for a year, we use the smallest share those figures show, so the comparison never overstates the difference.
Are these the same as breakdowns or known faults?
No. These are the items a tester recorded at the MOT, which covers condition and safety: lamps, brakes, tyres, suspension, corrosion and emissions. A gearbox that is unpleasant, an infotainment screen that has died, or a car that will not start on a cold morning are not part of the test, so they are not in these figures.
Where do the figures come from?
Every normal MOT test of a Hyundai Coupe aged three and over in Great Britain in 2025, from DVSA's anonymised MOT results. Retests are excluded, and the same fault on more than one wheel counts once.

Data sources and methodology
| Figures | Source | Period | Records | Updated |

- Shares for defects are of failed tests; shares for advisories are of all tests. A test can carry several defects, so shares add to more than 100%.
- The expected share is what an average car of the same registration years records, weighted by where this model’s failures fall. Where an item is outside the national figures for a year, the smallest share those figures show is used in its place, which is an upper bound, so the comparison never overstates a model’s problems. No expectation is published where less than 80% of the model’s failures can be compared.
- Great Britain only: DVSA does not run MOT testing in Northern Ireland. Cars under three years old are not tested.
- The descriptions of what each part does are general and the same on every model. Every figure comes from the MOT data.
