Jaguar X-Type 2003: reliability & common MOT faults

655 first-attempt MOT failures were recorded on the 2003 Jaguar X-Type in 2025. Figures are among first-attempt failed MOT tests, not among all tests.

Malfunction indicator lamp was the most common reason a 2003 X-Type failed its MOT — 16.8% 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 655 failed first attempts in 2025 that the age-and-mileage comparison can be computed on.

Standout: Suspension arm (rear) — 7.5% of this year's failed first attempts

Recorded on 49 of those tests. It tops the table on elevation — about 18× 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.

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.

Wear patterns

Usage and mileage effects that often track road use rather than model design.

These patterns look like wear or usage effects rather than model-specific design faults. Tyres, brake friction material, and alignment-related defects often track mileage and road use.

Brake discs (front)
Brakes > Mechanical brake components > Brake discs and drums > Brake discs
 Front 21 ×2.7 3.2% Wear
Tyres — Condition (front)
Tyres > Condition
 Front 69 ×2.1 10.5% Wear
Note: These patterns are not treated as a model design fault in our common-faults ranking.

Advisories

Advisory notes recorded on failed first-attempt tests that appear more often than on similar cars.

Note: Advisories are not a fail rate — they flag issues noted at the test, often before they become failures.

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 X-Types either side of it, so buy on the individual car. The checks below are the items that actually failed 2003 X-Types, commonest first.

What to check on a 2003 X-Type

The items that failed 2003 X-Types 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.

  • Malfunction indicator lamp — recorded on 16.8% of failed first attempts
  • Rbt (sp) — recorded on 11.1% of failed first attempts
  • Component mounting prescribed areas (rear) — recorded on 10.8% of failed first attempts
  • Tyres — Condition (front) — recorded on 10.5% of failed first attempts
  • Catalyst emissions — recorded on 9.8% 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.

Malfunction indicator lamp was the most common reason a 2003 X-Type failed its MOT — 16.8% of its failed first attempts. In 2025, 57.0% of 1,524 first MOTs on the 2003 Jaguar X-Type passed first time (PRS — items fixed at the station the same day — counted as a fail). The official-style rate including PRS is 63.4%. Among 655 failed first-attempt MOT tests (test year 2025), Suspension arm (rear) appears more often th…
Ranked by how often they were actually recorded, the items that failed 2003 Jaguar X-Types most often at the first attempt were Malfunction indicator lamp (16.8%), Rbt (sp) (11.1%) and Component mounting prescribed areas (rear) (10.8%) — 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-f…
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Suspension arm (rear) (7.5% of those tests; 49 observed failures; about 18× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Suspension arm (rear) shows up more often than on similar cars (7.5% of those tests; 49 observed failures; about 18× 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 2003 Jaguar X-Type include Suspension arm (rear), Sub-frame (rear), Pins and bushes (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 2003 Jaguar X-Type (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.
