Jaguar S-Type 2005: reliability & common MOT faults

In 2025, 61 in every 100 first MOTs on a 2005 Jaguar S-Type were passes. Most common reason for a fail: Track rod end (front).

Summary

The 2005 Jaguar S-Type follows the pattern of the model years either side.

What failed most often

  1. Track rod end (front)13 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 2005 Jaguar S-Type vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.

Suspension

One fault: suspension arm pins and bushes (rear), 6.4 times as often as on similar cars.

Figures below are measured across the 473 of 474 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.

Suspension arm pins and bushes (rear)

Failed on 24 first tests6.4 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 34 first tests, 3.4 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.

Steering

One fault: track rod end (front), 3.1 times as often as on similar cars.

Track rod end (front)

Failed on 61 first tests3.1 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. A dust cover that is damaged but still keeps dirt out is Minor, and one missing or no longer keeping dirt out is Major. Testers must tell wear from a joint's built-in clearance or spring loading.

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

Brakes

One fault and one wear pattern. The strongest is the brake pads (rear): 2.9 times as often as on similar cars.

Brake pads (rear)

Failed on 29 first tests2.9 times as often as similar carsWear pattern

What it means

A pad worn down to its wear indicator, or contaminated with oil or grease, is Major. A pad worn below the set thickness limit, missing or incorrectly mounted is Dangerous. The manual treats an illuminated brake wear indicator as no reason for failure, although DVSA also lists an illuminated indicator as a Major row.

Anti-lock braking system (ABS)

Failed on 25 first tests2.0 times as often as similar carsPossible evidence

What it means

ABS is failed as removed only where it has obviously been removed, because not every vehicle in the age range where removal is not permitted has ABS. A warning lamp that does not light or shows an ABS fault is Major, as is a missing or excessively damaged wheel speed sensor. Every failure row for this component is Major.

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.

Data: UK MOT open data, 2025. Counts cover advisories recorded on failed first tests only, compared with cars of the same age and mileage.

MOT pass rates

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

Passed first time

Passed on the first test.

Did not pass, and were not fixed at the test station.

First-attempt pass 61.0% of 1,215 first tests (2025): only cars that passed first time count. Official-style pass 66.1%: cars fixed at the test station also count as a pass. The 5 fixed and the 34 not fixed make the 39 in every 100 that did not pass first time.

Newer cars are younger, so look for a jump rather than the climb. A year earlier (2024), when these cars were a year younger, 60 in every 100 passed first time.

FAQs

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

The 2005 Jaguar S-Type follows the pattern of the model years either side. Its main cause of failure was Track rod end (front), about 13 in every 100 failed tests. In 2025, 61.0% of 1,215 first MOTs on the 2005 Jaguar S-Type 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 474 failed first-attempt MOT tests (test year 2025), Suspension arm pins and bushes (rear) appears more often than on similar cars (5.1% of those tests; 24 observed failures; about 6.4× 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 2005 Jaguar S-Type at the first attempt were Track rod end (front) (12.9%), 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: Suspension arm pins and bushes (rear) (5.1% of those tests; 24 observed failures; about 6.4× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Suspension arm pins and bushes (rear) shows up more often than on similar cars (5.1% of those tests; 24 observed failures; about 6.4× 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 2005 Jaguar S-Type include Suspension arm pins and bushes (rear), Track rod end (front), Anti-lock braking system (ABS). 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 2005 Jaguar S-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.
  • If the data for a car is too thin to say anything useful, we say so rather than guess.
