Known faults, from the test record

Mitsubishi Lancer common problems

What fails on the Mitsubishi Lancer at MOT, which parts are behind it, and how each model year compares. From 8,750 DVSA test records.

Data updated

Quick answer

The Mitsubishi Lancer's most common MOT problems are suspension bushes, bulbs and lamps, tyres, recorded in 43.4%, 40.3% and 19.6% of failed tests respectively. By model year, 2008 cars pass most often (64.0%) and 2011 cars least (58.2%), 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 Mitsubishi Lancer 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 8,750 cars.

By component

What wears out on a Lancer

Failure items grouped by the part behind them, with the share of failed Mitsubishi Lancer 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

    43.4% 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 pin, bush or joint excessively worn” — explained11.1%
    • “A suspension pin, bush or joint excessively worn” — explained6.7%
    • “A suspension pin, bush or joint excessively worn” — explained5.8%
    • “A suspension pin, bush or joint excessively worn” — explained5.2%

    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.Bulbs and lamps

    40.3% 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” — explained18.2%
    • “Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained9.5%
    • “A rear registration plate lamp or light source missing or inoperative in the case of a single lamp or all lamps” — explained6.4%
    • “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” — explained3.4%

    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

  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” — explained8.6%
    • “A tyre seriously damaged” — explained4.1%
    • “A tyre cords visible or damaged” — explained3.9%
    • “A tyre seriously damaged” — explained3.0%

    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.Ball joints

    19.4% of failed tests

    Steering and suspension ball joints wear internally and their dust covers split; excessive play fails.

    • “A steering ball joint with excessive wear or free play” — explained19.4%

    Across all cars, ball joints failures climb 28-fold between three and fifteen years, peaking at 12–14 years. How long ball joints last

  5. 5.Brake pipes

    13.5% of failed tests

    Steel pipes under the car corrode from salt and moisture, fastest on cars kept outside in wet or coastal areas; failure is for excessive corrosion or damage.

    • “Brake pipe damaged or excessively corroded” — explained13.5%

    Across all cars, brake pipes failures climb from nothing between three and fifteen years, peaking at 15+ years. How long brake pipes last

  6. 6.Wiper blades and washers

    12.5% 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” — explained8.3%
    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained4.2%

    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 arms and mountings

    11.6% of failed tests

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

    • “The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired” — explained8.6%
    • “A suspension component excessively damaged or corroded” — explained3.0%

  8. 8.Headlamp aim

    11.5% of failed tests

    Aim drifts with sagging suspension, a knocked lamp or a botched bulb change; adjustment, not a part.

    • “The aim of a headlamp is not within limits laid down in the requirements” — explained8.5%
    • “The aim of a headlamp is not within limits laid down in the requirements” — explained3.0%

By registration year

Lancer problems by year

MOT pass rate for Mitsubishi Lancer 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. No single step here is large enough to point at a generation change.

200864%
201061%−3.1
201158%−2.7

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 Mitsubishi Lancer?
Going by what fails the MOT, suspension bushes (recorded in 43.4% of failed tests), bulbs and lamps (recorded in 40.3% of failed tests), and tyres (recorded in 19.6% of failed tests). These are the items testers actually record across 8,750 tests, not reports from owners, so they describe what goes wrong at the point where it has to be fixed.
Which Mitsubishi Lancer year is the most reliable?
By MOT pass rate, Mitsubishi Lancer cars registered in 2008 do best at 64.0% and 2011 cars do worst at 58.2%. 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.
Is the Mitsubishi Lancer reliable?
The Mitsubishi Lancer passes 67.4% of MOTs unadjusted; its fleet is too narrow in age or mileage for a fair national comparison. 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 Mitsubishi Lancer?
Start with what fails most: suspension bushes, bulbs and lamps, 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.
