Vauxhall Mokka common problems
The most common reason a Vauxhall Mokka fails its MOT is a split joint boot, on 21.7% of its 78,127 failed tests in 2025. Against other cars of the same age, 6 faults stand out, the widest gaps being: a split joint boot at 21.7% of failures against 1.6% expected; a worn steering or suspension joint at 5.6% of failures against 1.9% expected; a sidelight out at 8.9% of failures against 4.0% expected.

What fails a Vauxhall Mokka MOT
Each bar is the share of failed Vauxhall Mokka 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 |
|---|---|
| Suspension arms: ball joint dust cover no longer prevents the ingress of dirt Suspension | 21.7% |
| Coil spring: fractured or broken Suspension | 16.2% |
| Wipers: does not clear the windscreen effectively Visibility | 10.8% |
| Position lamp: not working Lamps, reflectors and electrical equipment | 8.9% |
| Tyre pressure monitoring system: malfunctioning or obviously inoperative Tyres | 8.4% |
| Brake pads: less than 1.5 mm thick Brakes | 7.8% |
| Malfunction indicator lamp: inoperative or indicates a malfunction Noise, emissions and leaks | 6.8% |
| Suspension arms: ball joint excessively worn Suspension | 6.1% |
| Track rod end: ball joint dust cover excessively damaged or deteriorated so that it no longer prevents the ingress of dirt Steering | 5.6% |
| Headlamp: not working on dipped beam Lamps, reflectors and electrical equipment | 5.6% |
| Track rod end: ball joint has excessive play Steering | 5.4% |
| Tyres: tread depth below requirements of 1.6mm Tyres | 5.3% |

Split joint boot
21.7% of failures 1.6% expected 13.6 times as often
A split rubber boot on a joint or driveshaft. The joint may still be sound, but dirt and water get in once the boot is open.
Turn the wheels to full lock and look behind them for greasy splits in the rubber concertina.
-
Broken coil spring
16.2% of failures 8.7% expected 1.9 times as often
A broken suspension spring, which usually snaps in the bottom coil and often fails on both sides within a year.
Look at each corner for a sagging ride height, and listen for a knock over speed bumps.
-
Wiper blades that do not clear the screen
10.8% of failures 7.0% expected 1.5 times as 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.
-
Sidelight out
8.9% of failures 4.0% expected 2.2 times as 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 pressure warning
8.4% of failures 4.1% expected 2 times as often
The pressure monitoring system is not working, which fails the test on cars first used from 2012.
A warning light that stays on after the tyres are set correctly usually means a sensor has died.
-
Worn brake pads
7.8% of failures 8.0% expected about as expected
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.
Which parts of the car fail
Suspension is the area that most often fails a Vauxhall Mokka, on 46.8% of failed tests. That is also where it differs most from cars of the same registration years, which record 26.6%.

What testers warn about
48.5% of Vauxhall Mokka tests ended with at least one advisory: a fault the tester found that did not fail the test. On Vauxhall Mokkas, 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 | 14.1% |
| Tyres: slightly damaged or cracking or perishing Tyres | 11.6% |
| Brake pads: wearing thin Brakes | 9.1% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 7.9% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 6.9% |
| Exhaust system: minor leak of exhaust gases Body, chassis, structure | 4.9% |
| Brake discs: worn, but not excessively Brakes | 2.8% |
| Child seat fitted not allowing full inspection of adult belt Non-component advisories | 2.6% |
| Nail in tyre Non-component advisories | 2.6% |
| Macpherson strut: pin or bush worn but not resulting in excessive movement Suspension | 2.3% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 2.0% |
| Suspension arms: ball joint has slight play Suspension | 1.8% |

Vauxhall Mokka problems: common questions
What is the most common problem with a Vauxhall Mokka?
Of the faults that fail an MOT, “Suspension arms: ball joint dust cover no longer prevents the ingress of dirt” is the most common: it appears on 21.7% of failed Vauxhall Mokka tests. Across categories, suspension is the area that most often fails one, on 46.8% of failed tests.
How often does a Vauxhall Mokka fail its MOT?
30.8% of Vauxhall Mokka tests in 2025 were not passed first time, from 253,561 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 35 out of 100, where 50 is as expected.
Does anything fail more often on a Vauxhall Mokka than on other cars?
Yes. “Suspension arms: ball joint dust cover no longer prevents the ingress of dirt” appears on 21.7% of its failures against 1.6% for cars of the same age, and “Track rod end: ball joint dust cover excessively damaged or deteriorated so that it no longer prevents the ingress of dirt” appears on 5.6% of its failures against 1.9% 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 Vauxhall Mokka 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.
