Toyota Hilux 2005: reliability & common MOT faults

In 2025, 58 in every 100 first MOTs on a 2005 Toyota Hilux were passes. Most common reason for a fail: Rear fog light.

Summary

With 931 first tests, there are too few to say whether the 2005 Toyota Hilux differs from the model years either side.

What failed most often

  1. Rear fog light14 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 Toyota Hilux 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.

Lamps and electrical

Two faults. The strongest is the rear fog light: 7.0 times as often as on similar cars.

Figures below are measured across the 388 of 391 failed first attempts (99.2%) 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.

Rear fog light

Failed on 55 first tests7.0 times as often as similar carsLikely evidence

What it means

A missing obligatory rear fog lamp, one that is not working, or one that does not emit a steady red light is graded Major. A rear fog lamp adversely affected by the operation of any other lamp is Major too. The manual allows it to go out when main beam is switched on or when dipped beam headlamps are switched off.

Individual sidelight or tail light (rear)

Failed on 26 first tests2.2 times as often as similar carsPossible evidence

What it means

A position lamp showing red light to the front or white light to the rear is Major. Rear lamps must show a steady red light, and front ones can show white, predominantly white with a blue tinge, or yellow if combined in a yellow headlamp. With a multiple light source, up to half not working is Minor and more than half is Major.

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

Brakes

Two faults. The strongest is the brake imbalance across an axle (roller test, efficiency check, rear): 5.7 times as often as on similar cars.

Brake imbalance across an axle (roller test, efficiency check, rear)

Failed on 32 first tests5.7 times as often as similar carsLikely evidence

What it means

A wheel giving less than a set share of the maximum effort from the other wheel on the same axle is Major. On a steered axle, less than half is graded Dangerous. Testers disregard an imbalance if the lower effort is the result of a locked wheel, or if the higher effort from a wheel is at or below a low set figure.

Brake performance (roller test, rear)

Failed on 32 first tests3.0 times as often as similar carsLikely evidence

What it means

A wheel with no recorded braking effort on the roller test is graded Dangerous. Inadequate effort, a brake grabbing severely, abnormal lag and excessive fluctuation in effort are each Major. So is significant brake effort recorded with no brake applied, which indicates a binding brake.

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

Body and structure

One fault: chassis condition (rear), 3.8 times as often as on similar cars.

Chassis condition (rear)

Failed on 26 first tests3.8 times as often as similar carsPossible evidence

What it means

A main load-bearing structural member that is fractured, deformed, modified or inadequately repaired is Major when structural rigidity is significantly reduced, and Dangerous where steering or braking is likely to be adversely affected. Corrosion of the body, cab or chassis at a mounting point is Dangerous where overall security or stability is impaired.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 22 first tests, 3.1 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
58in every 100
Passed on the first test.
Fixed at the station
5in every 100
Failed, then fixed at the test station the same day.
Failed
37in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 58.0% of 931 first tests (2025): only cars that passed first time count. Official-style pass 63.2%: cars fixed at the test station also count as a pass. The 5 fixed and the 37 not fixed make the 42 in every 100 that did not pass first time.

Same model, other years

FAQs

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

With 931 first tests, there are too few to say whether the 2005 Toyota Hilux differs from the model years either side. Its main cause of failure was Rear fog light, about 14 in every 100 failed tests. In 2025, 58.0% of 931 first MOTs on the 2005 Toyota Hilux passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 63.2%. Among 391 failed first-attempt MOT tests (test year 2025), Rear fog light appears more often than on similar cars (14.2% of those tests; 55 observed failures; about 7.0× 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 Toyota Hilux at the first attempt were Rear fog light (14.2%), 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: Rear fog light (14.2% of those tests; 55 observed failures; about 7.0× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Rear fog light shows up more often than on similar cars (14.2% of those tests; 55 observed failures; about 7.0× 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 Toyota Hilux include Rear fog light, Brake imbalance across an axle (roller test, efficiency check, rear), Chassis condition (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 2005 Toyota Hilux (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.
