Suzuki Jimny 2004: reliability & common MOT faults

698 first-attempt MOT failures were recorded on the 2004 Suzuki Jimny in 2025. Figures are among first-attempt failed MOT tests, not among all tests.

Position lamp (front) was the most common reason a 2004 Jimny failed its MOT — 12.8% of its failed first attempts.

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 697 of 698 failed first attempts (99.9%) that recorded an odometer reading in 2025 — the subset the age-and-mileage comparison can be computed on.

Standout: Prescribed areas (rear) — 8.9% of this year's failed first attempts

Recorded on 62 of those tests. It tops the table on elevation — about 11× 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.

No patterns met the strongest callout thresholds on this page; showing the highest-lift rows that still cleared the display floors.

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.

Nothing separates this year from the Jimnys either side of it, so buy on the individual car. The checks below are the items that actually failed 2004 Jimnys, commonest first.

Other Jimny 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
2008 Jimny +5.2 pp better 66.5% 1,036
2007 Jimny -4.9 pp worse 57.3% 1,370

What to check on a 2004 Jimny

The items that failed 2004 Jimnys 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.

  • Position lamp (front) — recorded on 12.8% of failed first attempts
  • Catalyst emissions — recorded on 11.2% of failed first attempts
  • Chassis condition (rear) — recorded on 10.6% of failed first attempts
  • Service brake imbalance (rear) — recorded on 10.5% of failed first attempts
  • Headlamp aim — recorded on 10.0% 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.

Position lamp (front) was the most common reason a 2004 Jimny failed its MOT — 12.8% of its failed first attempts. In 2025, 59.1% of 1,707 first MOTs on the 2004 Suzuki Jimny passed first time (PRS — items fixed at the station the same day — counted as a fail). The official-style rate including PRS is 66.1%. Among 698 failed first-attempt MOT tests (test year 2025), Prescribed areas (rear) appears more often than on…
Ranked by how often they were actually recorded, the items that failed 2004 Suzuki Jimnys most often at the first attempt were Position lamp (front) (12.8%), Catalyst emissions (11.2%) and Chassis condition (rear) (10.6%) — 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 an…
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Prescribed areas (rear) (8.9% of those tests; 62 observed failures; about 11× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Prescribed areas (rear) shows up more often than on similar cars (8.9% of those tests; 62 observed failures; about 11× 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 2004 Suzuki Jimny include Prescribed areas (rear), Chassis condition (front), Service brake imbalance (rear). 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 2004 Suzuki Jimny (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.
