Known faults, from the test record

Land Rover Discovery common problems

What fails on the Land Rover Discovery at MOT, which parts are behind it, and how each model year compares. From 143,473 DVSA test records.

Data updated

Quick answer

The Land Rover Discovery's most common MOT problems are suspension bushes, bulbs and lamps, tyres, recorded in 37.7%, 25.4% and 21.6% of failed tests respectively. By model year, 2022 cars pass most often (88.6%) and 2006 cars least (62.1%), 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 Land Rover Discovery 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 143,473 cars.

By component

What wears out on a Discovery

Failure items grouped by the part behind them, with the share of failed Land Rover Discovery 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

    37.7% 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” — explained21.3%
    • “A suspension joint dust cover missing or no longer prevents the ingress of dirt etc” — explained6.1%
    • “A suspension pin, bush or joint excessively worn” — explained5.2%
    • “A suspension pin, bush or joint excessively worn” — explained5.1%

    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

    25.4% 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” — explained8.8%
    • “Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained5.5%
    • “A rear registration plate lamp or light source missing or inoperative in the case of a single lamp or all lamps” — explained5.0%
    • “A headlamp or light source missing, inoperative or more than ½ not functioning in the case of LED” — 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

    21.6% 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.

    • “A tyre seriously damaged” — explained9.1%
    • “Tyre tread depth not in accordance with the requirements” — explained6.8%
    • “A tyre cords visible or damaged” — explained5.7%

    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.Body and structure

    13.1% of failed tests

    Structural corrosion within 30 cm of a seat belt, suspension or steering mounting fails; it is a disease of age, salt and wet storage.

    • “Body, cab or chassis excessively corroded at a mounting point” — explained6.0%
    • “Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced” — explained3.6%
    • “Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced” — explained3.5%

  5. 5.Wiper blades and washers

    10.5% 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” — explained6.4%
    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained2.2%
    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained1.9%

    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.Brake pipes

    10.3% 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” — explained10.3%

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

  7. 7.Brake pads and shoes

    9.4% 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” — explained9.4%

    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.Headlamp aim

    8.3% 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” — explained3.3%
    • “The aim of a headlamp is not within limits laid down in the requirements” — explained2.8%
    • “The aim of a headlamp is not within limits laid down in the requirements” — explained2.1%

By registration year

Discovery problems by year

MOT pass rate for Land Rover Discovery 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.

Common questions

What are the most common problems with a Land Rover Discovery?
Going by what fails the MOT, suspension bushes (recorded in 37.7% of failed tests), bulbs and lamps (recorded in 25.4% of failed tests), and tyres (recorded in 21.6% of failed tests). These are the items testers actually record across 143,473 tests, not reports from owners, so they describe what goes wrong at the point where it has to be fixed.
Which Land Rover Discovery year is the most reliable?
By MOT pass rate, Land Rover Discovery cars registered in 2022 do best at 88.6% and 2006 cars do worst at 62.1%. 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 Land Rover Discovery reliable?
Adjusted for the age and mileage of the cars tested, the Land Rover Discovery passes 80.1% 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 Land Rover Discovery?
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.
