Known faults, from the test record

Vauxhall Adam common problems

What fails on the Vauxhall Adam at MOT, which parts are behind it, and how each model year compares. From 58,761 DVSA test records.

Data updated

Quick answer

The Vauxhall Adam's most common MOT problems are steering rack and column, shock absorbers, tyres, recorded in 36.4%, 27.1% and 22.3% of failed tests respectively. By model year, 2019 cars pass most often (78.0%) and 2014 cars least (61.9%), 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 Adam 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 58,761 cars.

By component

What wears out on a Adam

Failure items grouped by the part behind them, with the share of failed Vauxhall Adam 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.Steering rack and column

    36.4% 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” — explained29.7%
    • “Steering rack gaiter or ball joint dust cover missing or no longer prevents the ingress of dirt etc” — explained6.7%

  2. 2.Shock absorbers

    27.1% of failed tests

    Seals wear and the damper leaks fluid or loses its action; failure is for a leak or no damping, not for being tired.

    • “A shock absorber damaged to the extent that it does not function or showing signs of severe leakage” — explained25.8%
    • “A shock absorber bush excessively worn” — explained1.3%

    Across all cars, shock absorbers failures climb 7-fold between three and fifteen years, peaking at 15+ years. How long shock absorbers last

  3. 3.Tyres

    22.3% 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” — explained9.9%
    • “A tyre seriously damaged” — explained4.2%
    • “A tyre seriously damaged” — explained3.5%
    • “A tyre cords visible or damaged” — explained3.3%

    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.Coil springs

    21.0% 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” — explained21.0%

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

  5. 5.Bulbs and lamps

    11.1% of failed tests

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

    • “An obligatory rear fog lamp missing, or a front or rear fog lamp inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained4.2%
    • “A headlamp or light source missing, inoperative or more than ½ not functioning in the case of LED” — explained3.0%
    • “A rear registration plate lamp or light source missing or inoperative in the case of a single lamp or all lamps” — explained1.7%
    • “A reversing lamp inoperative” — explained1.3%

    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

  6. 6.Wiper blades and washers

    10.9% 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” — explained5.9%
    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained3.5%
    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained1.5%

    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

  7. 7.Suspension bushes

    8.5% 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 pin, bush, joint or bearing excessively worn” — explained4.0%
    • “A suspension pin, bush or joint excessively worn” — explained2.8%
    • “A suspension pin, bush or joint excessively worn” — explained1.7%

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

  8. 8.Suspension arms and mountings

    6.8% of failed tests

    Arms bend on impact and mountings corrode into the body; a corroded mounting is a structural item and fails as one.

    • “A suspension component excessively damaged or corroded” — explained6.8%

By registration year

Adam problems by year

MOT pass rate for Vauxhall Adam 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%
201462%−1.0
201563%+1.3
201665%+2.1
201767%+1.3
201871%+4.8
201978%+6.5

Last column: change on the previous year, in points. Years registered within the last three years have not yet been tested and are not shown.

Common questions

What are the most common problems with a Vauxhall Adam?
Going by what fails the MOT, steering rack and column (recorded in 36.4% of failed tests), shock absorbers (recorded in 27.1% of failed tests), and tyres (recorded in 22.3% of failed tests). These are the items testers actually record across 58,761 tests, not reports from owners, so they describe what goes wrong at the point where it has to be fixed.
Which Vauxhall Adam year is the most reliable?
By MOT pass rate, Vauxhall Adam cars registered in 2019 do best at 78.0% and 2014 cars do worst at 61.9%. 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 Adam reliable?
Adjusted for the age and mileage of the cars tested, the Vauxhall Adam passes 64.0% 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 Adam?
Start with what fails most: shock absorbers, tyres, coil springs. 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.
