2025 MOT results
Mitsubishi ASX common problems
The most common reason a Mitsubishi ASX fails its MOT is worn brake pads, on 12.1% of its 7,319 failed tests in 2025. Against other cars of the same age, 7 faults stand out, the widest gaps being: corroded brake pipes at 7.8% of failures against 1.1% expected; a braking fault at 4.9% of failures against 1.4% expected; a worn steering or suspension joint at 5.7% of failures against 2.0% expected.

- Found a dangerous defect 7.1% Unsafe to drive away
- Ended with an advisory 55.7% A problem to watch, not a failure
What fails a Mitsubishi ASX MOT
Each bar is the share of failed Mitsubishi ASX 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 |
|---|---|
| Brake pads: less than 1.5 mm thick Brakes | 12.1% |
| Position lamp: not working Lamps, reflectors and electrical equipment | 9.0% |
| Tyres: tread depth below requirements of 1.6mm Tyres | 8.5% |
| Parking brake efficiency below requirements Brakes | 8.3% |
| Wipers: does not clear the windscreen effectively Visibility | 8.0% |
| Rigid brake pipes: excessively corroded Brakes | 7.8% |
| Track rod end: ball joint has excessive play Steering | 7.3% |
| Linkage ball joint dust cover no longer prevents the ingress of dirt Suspension | 5.8% |
| Linkage ball joint excessively worn Suspension | 5.7% |
| Suspension arms: ball joint excessively worn Suspension | 5.5% |
| Exhaust system: major leak of exhaust gases Body, chassis, structure | 5.1% |
| Parking brake performance: inoperative on one side Brakes | 4.9% |

Worn brake pads
12.1% of failures 7.1% expected 1.7 times as often
Friction material worn under 1.5mm, thinner than the point most manufacturers call the limit.
Look through the wheel spokes at the pad against the disc; wear indicators squeal before they get this far.
-
Sidelight out
9.0% of failures 6.9% expected somewhat more often
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.
-
Tyre worn below the legal limit
8.5% of failures 8.6% expected about as expected
A tyre worn past the 1.6mm legal minimum across the middle three quarters of the tread.
A 20p coin in the main grooves: if the outer band of the coin is visible, the tyre is close to the limit.
-
Weak handbrake
8.3% of failures 3.2% expected 2.6 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.
-
Wiper blades that do not clear the screen
8.0% of failures 6.0% expected somewhat more often
Wiper blades that leave the windscreen smeared or streaked across the area the driver looks through.
Look for split or hardened rubber, and lift each blade to see whether it still sits flat.
-
Corroded brake pipes
7.8% of failures 1.1% expected 7.1 times as often
Corroded or damaged brake pipework. It is a safety item, and on older cars the rear pipes go first.
Look along the pipes under the sills with a torch; flaking rust rather than surface staining is the problem.
Which parts of the car fail
Brakes is the area that most often fails a Mitsubishi ASX, on 36.8% of failed tests. That is also where it differs most from cars of the same registration years, which record 20.7%.

What testers warn about
55.7% of Mitsubishi ASX tests ended with at least one advisory: a fault the tester found that did not fail the test. On Mitsubishi ASX cars, 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 | 18.4% |
| Brake pads: wearing thin Brakes | 13.7% |
| Rigid brake pipes: corroded, covered in grease or other material Brakes | 11.8% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 10.7% |
| Tyres: slightly damaged or cracking or perishing Tyres | 7.7% |
| Sub-frame: corroded but not seriously weakened Suspension | 5.8% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 3.5% |
| Child seat fitted not allowing full inspection of adult belt Non-component advisories | 3.1% |
| Coil spring: corroded Suspension | 3.1% |
| Shock absorbers: light misting of oil Suspension | 2.7% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 2.7% |
| Brake discs: worn, but not excessively Brakes | 2.6% |

Mitsubishi ASX problems: common questions
What is the most common problem with a Mitsubishi ASX?
Of the faults that fail an MOT, “Brake pads: less than 1.5 mm thick” is the most common: it appears on 12.1% of failed Mitsubishi ASX tests. Across categories, brakes is the area that most often fails one, on 36.8% of failed tests.
How often does a Mitsubishi ASX fail its MOT?
25.5% of Mitsubishi ASX tests in 2025 were not passed first time, from 28,733 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 54 out of 100, where 50 is as expected.
Does anything fail more often on a Mitsubishi ASX than on other cars?
Yes. “Rigid brake pipes: excessively corroded” appears on 7.8% of its failures against 1.1% for cars of the same age, and “Parking brake performance: inoperative on one side” appears on 4.9% of its failures against 1.4% 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 Mitsubishi ASX 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 |
|---|---|---|---|---|
| MOT defects and advisories | Anonymised MOT tests and results Driver and Vehicle Standards Agency Derived statistics UK Motoring | 2025 | 28,733 MOT tests | 19 September 2026 |
- 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.
