Vauxhall Mokka common problems

What fails on the Vauxhall Mokka at MOT, which parts are behind it, and how each model year compares. From 254,046 DVSA test records.

Data updated

Quick answer

The Vauxhall Mokka's most common MOT problems are suspension bushes, coil springs, tyres, recorded in 55.4%, 22.1% and 19.6% of failed tests respectively. By model year, 2022 cars pass most often (89.3%) and 2013 cars least (62.5%), though most of that gap is age. Every figure here is what testers recorded, not what owners reported.

A “common problems” list is usually a forum thread: whoever had the worst day writes the longest post. This one is built the other way, from every Vauxhall Mokka that took an MOT last year and what the tester wrote down. It cannot see breakdowns, electrical gremlins or a gearbox that hunts, because the test does not check those. What it can see, it sees across 254,046 cars.

By component

What wears out on a Mokka

Failure items grouped by the part behind them, with the share of failed Vauxhall Mokka tests recording each. A part can carry several DVSA wordings; they are listed beneath. One failed test often lists several items, so shares do not sum to 100%.

  1. 1.Suspension bushes

    55.4% of failed tests

    Rubber bushes in arms and links perish and split with age and load; the most recorded suspension item on the test.

    • “A suspension joint dust cover missing or no longer prevents the ingress of dirt etc” — explained37.1%
    • “A suspension pin, bush or joint excessively worn” — explained8.3%
    • “A suspension pin, bush or joint excessively worn” — explained2.3%
    • “A suspension pin, bush or joint excessively worn” — explained2.2%

    Across all cars, suspension bushes failures climb 20-fold between three and fifteen years, peaking at 15+ years. How long suspension bushes last

  2. 2.Coil springs

    22.1% of failed tests

    Springs fatigue and corrode where the coating chips, then snap, often at the bottom coil; potholes and salt accelerate it.

    • “A spring or spring component fractured or seriously weakened” — explained22.1%

    Across all cars, coil springs failures climb 20-fold between three and fifteen years, peaking at 12–14 years. How long coil springs last

  3. 3.Tyres

    19.6% of failed tests

    Tread wears with every mile and sidewalls age and take kerb damage; the legal minimum is 1.6 mm across the central three-quarters.

    • “Tyre tread depth not in accordance with the requirements” — explained8.3%
    • “A tyre seriously damaged” — explained4.8%
    • “A tyre cords visible or damaged” — explained3.7%
    • “A tyre seriously damaged” — explained2.8%

    Across all cars, tyres failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long tyres last

  4. 4.Bulbs and lamps

    16.8% of failed tests

    Filament bulbs simply expire; the cheapest and most avoidable failure on the test, and one of the most recorded.

    • “A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained7.3%
    • “A headlamp or light source missing, inoperative or more than ½ not functioning in the case of LED” — explained4.3%
    • “A rear registration plate lamp or light source missing or inoperative in the case of a single lamp or all lamps” — explained1.9%
    • “Lamp emitted colour, position or intensity not in accordance with the requirements” — explained1.9%

    Across all cars, bulbs and lamps failures climb 15-fold between three and fifteen years, peaking at 15+ years. How long bulbs and lamps last

  5. 5.Wiper blades and washers

    14.9% of failed tests

    Rubber blades harden and split within a year or two; washer jets block and pumps fail.

    • “Wiper blade missing or obviously not clearing the windscreen” — explained11.8%
    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained2.0%
    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained1.1%

    Across all cars, wiper blades and washers failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long wiper blades and washers last

  6. 6.Steering rack and column

    10.8% of failed tests

    Rack gaiters split and let dirt in; the rack itself and the column are rarely the failing part.

    • “Steering rack gaiter or ball joint dust cover missing or no longer prevents the ingress of dirt etc” — explained9.0%
    • “Steering rack gaiter or ball joint dust cover missing or no longer prevents the ingress of dirt etc” — explained1.8%

  7. 7.Brake pads and shoes

    10.3% of failed tests

    Friction material wears with use; the MOT limit is 1.5 mm and a pad that thin is close to metal on metal.

    • “a brake lining or pad worn below 1.5mm” — explained10.3%

    Across all cars, brake pads and shoes failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long brake pads and shoes last

  8. 8.Tyre pressure sensors

    8.9% of failed tests

    Valve-mounted sensors have sealed batteries that expire after roughly seven to ten years; a system fault lamp is a failure on cars first used from 2012.

    • “A tyre pressure monitoring system malfunctioning or obviously inoperative” — explained8.9%

By registration year

Mokka problems by year

MOT pass rate for Vauxhall Mokka cars by the year they were first registered, from years with at least 1,000 tests. Every car in a row is the same age, so the rate is raw. Neighbouring years differ by a year of wear — a step of a point or two is age. The step at 2019, up 6.5 points, is larger than wear explains and most likely marks a change in the cars themselves.

201363%
201463%+0.5
201563%−0.3
201663%−0.2
201767%+4.4
201871%+4.0
201977%+6.5
202183%+5.9
202289%+6.0

Common questions

What are the most common problems with a Vauxhall Mokka?
Going by what fails the MOT, suspension bushes (recorded in 55.4% of failed tests), coil springs (recorded in 22.1% of failed tests), and tyres (recorded in 19.6% of failed tests). These are the items testers actually record across 254,046 tests, not reports from owners, so they describe what goes wrong at the point where it has to be fixed.
Which Vauxhall Mokka year is the most reliable?
By MOT pass rate, Vauxhall Mokka cars registered in 2022 do best at 89.3% and 2013 cars do worst at 62.5%. Most of that ordering is simply age — newer cars pass more — so read the year table for steps larger than a couple of points between neighbouring years; those mark a change in the cars rather than the calendar. The largest such step is at 2019, up 6.5 points on 2018.
Is the Vauxhall Mokka reliable?
Adjusted for the age and mileage of the cars tested, the Vauxhall Mokka passes 68.6% of MOTs against a national 72.3%. An MOT measures roadworthiness on the day rather than breakdowns or running costs, so this is a reliability measure in the narrow sense: how often the car meets the legal standard, and what stops it.
What should I check when buying a used Vauxhall Mokka?
Start with what fails most: suspension bushes, coil springs, tyres. Then read the car's own MOT history for advisories carried year to year without repair — the model tells you what to expect, the history tells you whether this owner dealt with it.
