Ford Focus 2008: reliability & common MOT faults

In 2025, 55 in every 100 first MOTs on a 2008 Ford Focus were passes. Most common reason for a fail: Individual sidelight or tail light (front).

Summary

The 2008 Ford Focus follows the pattern of the model years either side.

What failed most often

  1. Individual sidelight or tail light (front)14 in every 100 failed tests
  2. Headlight aim11 in every 100 failed tests
  3. Suspension arm pins and bushes (front)8 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 2008 Ford Focus 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.

Suspension

Two faults. The strongest is the anti-roll bar linkage (rear): 15 times as often as on similar cars.

Figures below are measured across the 16,507 of 16,714 failed first attempts (98.8%) 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.

Anti-roll bar linkage (rear)

Failed on 504 first tests15 times as often as similar carsStrong evidence

What it means

An anti-roll bar linkage is graded Dangerous when a suspension component is missing, likely to become detached, fractured or likely to fail. Insecure attachment that impairs directional stability is graded Dangerous too. Excessive damage or corrosion that seriously weakens the part is Major, and so is plain insecure attachment to the chassis or axle.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 38 first tests, 10 times as often as on similar cars.

Suspension arm pins and bushes (rear)

Failed on 341 first tests2.4 times as often as similar carsPossible evidence

What it means

Pins and bushes on suspension arms fail as Major when they are excessively worn. They are graded Dangerous when likely to become detached. DVSA uses the same wording for a suspension joint.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 751 first tests, 2.0 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.

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.

MOT pass rates

How first tests ended, and how the pass rates are counted.

Passed first time
55in every 100
Passed on the first test.
Fixed at the station
10in every 100
Failed, then fixed at the test station the same day.
Failed
35in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 55.2% of 37,319 first tests (2025): only cars that passed first time count. Official-style pass 64.6%: cars fixed at the test station also count as a pass. The 10 fixed and the 35 not fixed make the 45 in every 100 that did not pass first time.

Petrol and diesel

First testsTypical mileagePassed first time, as testedPassed first time, same mileage
Petrol30,524102,900 miles5655

If you are buying one

What this year's MOT record means for the decision in front of you.

Mileage matters most on a 2008 Focus.

Of 2008 Focus vehicles with under 78,000 miles, 68 in every 100 passed their 2025 MOT first time. With 136,000 miles or more, 48 in every 100 did.

Petrol or diesel?

Typical mileagePassed first time,
as tested		Passed first time,
same mileage
Petrol102,900 miles5655
Diesel125,418 miles5355

Figures are in every 100 first tests. Petrol cars look better on the raw figures only because diesel cars have done more miles (typically 125,418 against 102,900). At the same mileage there is no clear difference between the two.

What to check at your mileage

How often each fault turned up on a failed first test, by the car's mileage. Read it as: what is likely to need looking at on a car like the one in front of you.

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 2008 Ford Focus follows the pattern of the model years either side. Its main cause of failure was Individual sidelight or tail light (front), about 14 in every 100 failed tests. In 2025, 55.2% of 37,319 first MOTs on the 2008 Ford Focus passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 64.6%. Among 16,714 failed first-attempt MOT tests (test year 2025), Anti-roll bar linkage (rear) appears more often than on similar cars (3.1% of those tests; 504 observed failures; about 15× 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 2008 Ford Focus at the first attempt were Individual sidelight or tail light (front) (13.6%), Headlight aim (11.4%) and Suspension arm pins and bushes (front) (8.0%), 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: Anti-roll bar linkage (rear) (3.1% of those tests; 504 observed failures; about 15× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Anti-roll bar linkage (rear) shows up more often than on similar cars (3.1% of those tests; 504 observed failures; about 15× 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 2008 Ford Focus include Anti-roll bar linkage (rear), Suspension arm pins and bushes (rear). 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 2008 Ford Focus (registration year) using UK DVSA open data for the selected test year. Patterns are compared with cars of a similar age and mileage. It is a buyer checklist from MOT defect statistics, not a full service history or manufacturer service-bulletin list.
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.
