Toyota Alphard 2006: reliability & common MOT faults

In 2025, 73 in every 100 first MOTs on a 2006 Toyota Alphard were passes. Most common reason for a fail: Anti-roll bar linkage ball joint dust cover (front).

What failed most often

  1. Anti-roll bar linkage ball joint dust cover (front)15 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 2006 Toyota Alphard 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.

Lamps and electrical

One fault: rear fog light, 6.7 times as often as on similar cars.

Figures below are measured across the 364 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.

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 40 first tests6.7 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.

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

Suspension

One fault: anti-roll bar linkage ball joint dust cover (front), 3.3 times as often as on similar cars.

Anti-roll bar linkage ball joint dust cover (front)

Failed on 53 first tests3.3 times as often as similar carsLikely evidence

What it means

A suspension joint dust cover that is severely deteriorated is Minor. It becomes Major once it is missing or no longer prevents the ingress of dirt, so what matters is whether it still keeps dirt out. DVSA words this for any suspension joint dust cover, and files it here under anti-roll bars.

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

Visibility

One fault: windscreen wipers (front), 2.4 times as often as on similar cars.

Windscreen wipers (front)

Failed on 36 first tests2.4 times as often as similar carsPossible evidence

What it means

Only a clearly damaged or worn windscreen wiper needs to be rejected. A wiper that is missing or not working is graded Major, and so is a blade that is missing or obviously not clearing the windscreen. A defective blade is graded Minor.

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

Tyres

One wear pattern: tyre condition (rear), 2.3 times as often as on similar cars.

Tyre condition (rear)

Failed on 41 first tests2.3 times as often as similar carsWear pattern

What it means

Exposed or damaged ply or cords are graded Dangerous. A cut in excess of the requirements and deep enough to reach the ply or cords is Major, and testers may open the cut with a blunt instrument to check its depth. A tyre contacting the vehicle through flexing or suspension movement is not a defect; fouling fails only at the time of test.

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.

Swivel pins and bushes (rear)

Noted on 32 first tests6.5 times as often as similar carsElevated evidence

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
73in every 100
Passed on the first test.
Fixed at the station

Failed, then fixed at the test station the same day.
Failed
22in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 73.2% of 1,358 first tests (2025): only cars that passed first time count. Official-style pass 78.2%: cars fixed at the test station also count as a pass. The 5 fixed and the 22 not fixed make the 27 in every 100 that did not pass first time.

FAQs

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

The 2006 Toyota Alphard follows the pattern of the model years either side. Its main cause of failure was Anti-roll bar linkage ball joint dust cover (front), about 15 in every 100 failed tests. In 2025, 73.2% of 1,358 first MOTs on the 2006 Toyota Alphard passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 78.2%. Among 364 failed first-attempt MOT tests (test year 2025), Rear fog light appears more often than on similar cars (11.0% of those tests; 40 observed failures; about 6.7× 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 2006 Toyota Alphard at the first attempt were Anti-roll bar linkage ball joint dust cover (front) (14.6%), 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 (11.0% of those tests; 40 observed failures; about 6.7× 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 (11.0% of those tests; 40 observed failures; about 6.7× 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 2006 Toyota Alphard include Rear fog light, Anti-roll bar linkage ball joint dust cover (front), Windscreen wipers (front). 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 2006 Toyota Alphard (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.
