23,938 first-attempt MOT failures were recorded on the 2012 Ford Focus in 2025. The items recorded most often on them were Coil spring (front) and Position lamp (front). Figures are among first-attempt failed MOT tests, not among all tests.

Petrol Focus passed first time 4.1 pp more often than diesel ones (63.1% of 35,694 vs 59.0% of 26,220).

Note:

  • Class 4 cars · first MOT of the year per vehicle · P/PRS/F outcomes (2025 data).
  • PRS (fixed at the station the same day) counts as a fail in the first-attempt rate.
  • Raw outcomes for this cohort — not adjusted for age, mileage, or peer mix.
  • MOT doesn't test engine or gearbox internals.

Common faults

Failure patterns that show up more often on this registration year than on similar cars.

These MOT failure patterns show up more often on this registration year than on similar cars of the same class, age, and mileage.

Shares below are measured across the 23,886 of 23,938 failed first attempts (99.8%) that recorded an odometer reading in 2025 — the subset the age-and-mileage comparison can be computed on.

Standout: Anti-roll bars — Linkage (rear) — 4.9% of this year's failed first attempts

Recorded on 1,160 of those tests. It tops the table on elevation — about 22× more often than on similar cars of the same age and mileage. That is what makes it unusual for its class, which is a different question from what is most likely to fail; the buying checklist ranks by that. The full ranked list is in the table below.

Fault pattern Location Failures vs similar cars Share of fails Confidence
Anti-roll bars — Linkage (rear)
Suspension > Anti-roll bars > Linkage
 Rear 1,160 ×22 4.9% Strong
Individual direction indicators (front)
Lamps, reflectors and electrical equipment > Direction indicators > Flashing type > Individual direction indicators
 Front 806 ×3.5 3.4% Likely
Electrical equipment — Horn
Lamps, reflectors and electrical equipment > Electrical equipment > Horn
 Any 777 ×3.1 3.3% Likely
Coil spring (front)
Suspension > Springs > Coil springs > Coil spring
 Front 3,342 ×2.1 14.0% Possible

Only patterns that clear minimum sample and elevation thresholds are shown (at least 20 failures and about 2.0× more often than similar cars).

Note: Rates and comparisons are among first-attempt failed tests, not all MOTs. Patterns come from MOT defect codes — not manufacturer service bulletins, recalls, or a diagnosis of any individual car. Failures and advisories are listed separately.

If you are buying one

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

On this year, prefer the petrol. The diesel cars passed first time 4.1 pp less often, on 26,220 tests.

This year also sits 1.5 pp above the midpoint of the 2011 and 2013 cars either side of it — a real break in the model's own run, not the usual year-on-year drift.

Other Focus years worth knowing about

Newer cars always pass more often, so a plain "best year" list would just rank by age. These are the years that beat or miss the trend their own neighbouring years set — the only age-adjusted signal this data supports.

Year vs the years either side First-attempt pass (rises with newer cars) First tests
2015 Focus +1.8 pp better 72.2% 71,323
2014 Focus -3.0 pp worse 64.0% 69,468
2011 Focus -1.0 pp worse 57.7% 57,244

What to check on a 2012 Focus

The items that failed 2012 Focus most often, as a share of the year's failed first attempts. This is what goes wrong, not what is unusual — the table further up the page covers that.

  • Coil spring (front) — recorded on 14.0% of failed first attempts
  • Position lamp (front) — recorded on 12.5% of failed first attempts
  • Headlamp aim — recorded on 10.3% of failed first attempts
  • Drive shafts — Joints (front) — recorded on 7.3% of failed first attempts
  • Tread depth (front) — recorded on 6.7% of failed first attempts

Every figure here is a first-attempt MOT rate from DVSA open data for this model line. 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.

Petrol Focus passed first time 4.1 pp more often than diesel ones (63.1% of 35,694 vs 59.0% of 26,220). In 2025, 61.3% of 61,916 first MOTs on the 2012 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 69.6%. Among 23,938 failed first-attempt MOT tests (test year 2025), Anti-roll bars — Linkage (rear) appears more often than on…
Ranked by how often they were actually recorded, the items that failed 2012 Ford Focuss most often at the first attempt were Coil spring (front) (14.0%), Position lamp (front) (12.5%) and Headlamp aim (10.3%) — each as a share of the year's failed first attempts. That is what goes wrong on the car. It is a different question from which patterns are unusual for the class, which the common-faults table answers.
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Anti-roll bars — Linkage (rear) (4.9% of those tests; 1,160 observed failures; about 22× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Anti-roll bars — Linkage (rear) shows up more often than on similar cars (4.9% of those tests; 1,160 observed failures; about 22× 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 check point, not a manufacturer service bulletin.
Common MOT problem areas for the 2012 Ford Focus include Anti-roll bars — Linkage (rear), Individual direction indicators (front), Electrical equipment — Horn. These patterns show up more often than on similar cars after we filter out sparse noise — not a full list of every possible fault on an 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 2012 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.
  • We never invent pass rates, star scores, or ranks when those data marts are missing.
