  2. Headlight aim10 in every 100 failed tests
  3. Individual sidelight or tail light (front)9 in every 100 failed tests

How we count this. Data: UK MOT open data, 2025. Only Class 4 cars on their first MOT of the year are counted. A car that fails and is fixed at the test station still counts as a fail in the first-attempt rate. These are raw results, not adjusted for age, mileage, or peer mix. The MOT does not test engine or gearbox internals.

Note:

These are patterns across 2010 Land Rover Defender vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.

Steering

Two faults. The strongest is the steering drag link end (front): 81 times as often as on similar cars.

Figures below are measured across the 1,170 of 1,172 failed first attempts (99.8%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like.

We only list faults with at least 20 failures and a rate of about 2.0 times that of similar cars, which keeps one-off results out of the list.

Steering drag link end (front)

Failed on 51 first tests81 times as often as similar carsLikely evidence

What it means

A steering ball joint with excessive wear or free play is Major, and one worn to the extent there is a serious risk of detachment is graded Dangerous. Track rod or drag link ends that are seriously misaligned are Major. An unsafe modification to the steering linkage is Major, and Dangerous where the steering is affected.

Steering ball joint (front)

Failed on 43 first tests24 times as often as similar carsLikely evidence

What it means

A steering ball joint with excessive wear or free play is graded Major, and one worn to the extent that there is a serious risk of detachment is graded Dangerous. Movement from excessive wear is distinguished from built-in clearance or spring loading of a joint. A dust cover that is damaged but still keeps dirt out is Minor.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Suspension

Two faults. The strongest is the suspension arm ball joint dust cover (rear): 63 times as often as on similar cars.

Suspension arm ball joint dust cover (rear)

Failed on 35 first tests63 times as often as similar carsLikely evidence

What it means

Whether a suspension arm ball joint dust cover still keeps dirt out decides its grade. Severely deteriorated is Minor, while missing, or no longer preventing the ingress of dirt, is Major.

Shock absorbers (rear)

Failed on 126 first tests3.9 times as often as similar carsLikely evidence

What it means

Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 153 first tests, 4.1 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Seat belts and restraints

One fault: seat belt condition (front), 12 times as often as on similar cars.

Seat belt condition (front)

Failed on 42 first tests12 times as often as similar carsLikely evidence

What it means

Any sign of overstretching is a deficiency, and so is a cut anywhere on a child seat belt. On other belts the size of a cut decides it, with a stricter limit at the webbing edge than away from it. Webbing significantly stretched or weakened has rows in both Major and Dangerous grades.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 153 first tests, 17 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Lamps and electrical

One fault: reversing lights, 9.2 times as often as on similar cars.

Reversing lights

Failed on 75 first tests9.2 times as often as similar carsLikely evidence

What it means

Reversing lamps must show a white light to the rear, and on some vehicles the engine has to be running before they work. A lamp that does not emit a steady white light, does not face the rear or has its light intensity significantly reduced is Major. A lamp not securely attached is Minor, but one likely to become detached is Major.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Body and structure

One fault: chassis condition (rear), 8.8 times as often as on similar cars.

Chassis condition (rear)

Failed on 44 first tests8.8 times as often as similar carsLikely evidence

What it means

A main load-bearing structural member that is fractured, deformed, modified or inadequately repaired is Major when structural rigidity is significantly reduced, and Dangerous where steering or braking is likely to be adversely affected. Corrosion of the body, cab or chassis at a mounting point is Dangerous where overall security or stability is impaired.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 41 first tests, 6.6 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Brakes

Two faults. The strongest is the brake efficiency below minimum (roller test): 8.6 times as often as on similar cars.

Brake efficiency below minimum (roller test)

Failed on 65 first tests8.6 times as often as similar carsLikely evidence

What it means

Service brake efficiency below the minimum requirement is Major, and efficiency less than half of the required value is graded Dangerous. On a roller brake tester, if more than half of the wheels of a brake system lock, the efficiency requirement for that system counts as met.

Rigid brake pipes (front)

Failed on 73 first tests6.7 times as often as similar carsLikely evidence

What it means

Chafing, corrosion or damage to a rigid brake pipe justifies rejection once its wall thickness is reduced by a set amount, although DVSA accepts this is not easy to determine. If a tester is not sure, the benefit of the doubt applies. A leaking pipe or connection is graded Dangerous on a hydraulic system and Major on an air system.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 198 first tests, 6.1 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Number plates and VIN

One fault: number plates (front), 3.9 times as often as on similar cars.

Number plates (front)

Failed on 28 first tests3.9 times as often as similar carsPossible evidence

What it means

A number plate that is missing, illegible, showing an incorrect registration or so insecure that it is likely to fall off is Major. Testers do not measure the characters or their spacing and reject them only if they are obviously incorrect. Delamination and the position of fixing screws or bolts get particular attention, as they can prevent number plate recognition cameras identifying the vehicle.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Advisories

Other things testers noted as worn or close to failing, more often than on similar cars.

An advisory is a note from the tester about something that has not failed yet. It is an early warning, not a fail. Advisories for the faults above are shown with those faults.

Every figure here is a first-attempt MOT rate from DVSA open data for this model line, for cars of this model year tested in 2025. Each mileage band holds a fifth of the tests. MOTs do not test engine or gearbox internals, so this is a pre-purchase checklist, not a full reliability score.

FAQs

Short answers about how to read this model-year guide.

The 2010 Land Rover Defender follows the pattern of the model years either side. Its main cause of failure was Shock absorbers (rear), about 11 in every 100 failed tests. In 2025, 67.8% of 3,642 first MOTs on the 2010 Land Rover Defender passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 73.1%. Among 1,172 failed first-attempt MOT tests (test year 2025), Steering drag link end (front) appears more often than on similar cars (4.4% of those tests; 51 observed failures; about 81× more often than similar cars). There is no single reliability score here; this is a pre-purchase checklist built from DVSA open data, not a guarantee for any individual car.
Ranked by how often they were actually recorded, the items that most often failed a 2010 Land Rover Defender at the first attempt were Shock absorbers (rear) (10.8%), Headlight aim (9.6%) and Individual sidelight or tail light (front) (9.2%), each as a share of the year's failed first attempts. That is what goes wrong most often on the car. The common faults table shows a different measure: faults that are unusual compared with similar cars.
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Steering drag link end (front) (4.4% of those tests; 51 observed failures; about 81× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Steering drag link end (front) shows up more often than on similar cars (4.4% of those tests; 51 observed failures; about 81× more often than similar cars). That does not prove a design fault. Age, mileage, and how the car was used still matter. Treat it as a pre-purchase checkpoint, not a manufacturer service bulletin.
Common MOT problem areas for the 2010 Land Rover Defender include Steering drag link end (front), Suspension arm ball joint dust cover (rear), Steering ball joint (front). These are the faults that stand out compared with similar cars, not a complete list of what can go wrong on any individual car.
Advisories flag issues noted at the test and are not a fail rate. We show advisory patterns that appear more often than on similar cars among failed first-attempt tests, separate from common failure rows. Use them as early-warning checks, not as a pass/fail score.
This page highlights MOT failure patterns for the 2010 Land Rover Defender (registration year) using UK DVSA open data for the selected test year.

No. MOT tests do not cover engine internals, gearboxes, or many electronic modules. Patterns here come from MOT defect statistics only and should not be read as engine or gearbox reliability scores.

About this data

How this page is built and what it can (and can't) say.

These figures come from UK MOT open data for this model year. We surface common failure patterns against similar cars, not a full reliability score, and not a pass/fail verdict on any individual vehicle.

2024 2025

What we include

UK Class 4 cars only. Normal MOT tests (not retests); first test per vehicle per calendar year; results pass, PRS, or fail.

Same-day repairs

PRS means the car failed items that were fixed at the test station and then passed the same day. We count PRS as a first-attempt fail in headline rates so same-day repairs do not hide problems.

How we compare

We compare this model year with other Class 4 cars of similar age and mileage in the same test year. This model family is left out of the peer group so the car is not measured against itself.

What this does not cover

  • MOTs do not cover engine internals, gearboxes, or many electronics; this is not a full reliability score.
  • Common faults come from MOT defect stats, not manufacturer TSBs or recalls.
  • Age and mileage matching reduces, but does not remove, differences in how cars were used and maintained.
  • If the data for a car is too thin to say anything useful, we say so rather than guess.
