SEAT Ibiza 2006: reliability & common MOT faults

In 2025, 49 in every 100 first MOTs on a 2006 SEAT Ibiza were passes. Most common reason for a fail: Individual sidelight or tail light (front).

Summary

The 2006 SEAT Ibiza follows the pattern of the model years either side.

  3. Brake light11 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 SEAT Ibiza 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.

Body and structure

Two faults. The strongest is the body panel (front): 12 times as often as on similar cars.

Figures below are measured across the 994 of 995 failed first attempts (99.9%) 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.

Body panel (front)

Failed on 22 first tests12 times as often as similar carsPossible evidence

What it means

A body panel that is damaged or corroded and likely to cause injury when grazed or contacted, or that is insecure, is Major. One likely to become detached is graded Dangerous. The inspection covers all body panels, undertrays, spoilers and mirror housings.

Exhaust system (front)

Failed on 21 first tests2.2 times as often as similar carsPossible evidence

What it means

Exhaust fumes causing a danger to health of persons on board are graded Dangerous, and so is a silencer likely to become detached. Fumes entering the cabin are Major. One or more missing or defective mountings does not necessarily make the exhaust insecure, since testers assess the overall security of the system.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 39 first tests, 2.3 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.

Suspension

Two faults. The strongest is the suspension arm (front): 5.6 times as often as on similar cars.

Suspension arm (front)

Failed on 21 first tests5.6 times as often as similar carsPossible evidence

What it means

A missing bump stop rubber is not a reason to fail a suspension arm. A component that is fractured, missing or likely to fail is graded Dangerous, and one excessively damaged or corroded is Major. On some vehicles, some highly stressed parts are thin pressed steel, and many of those have hollow box sections or up-facing areas that can collect road dirt and salt, so they get special attention.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 78 first tests, 3.6 times as often as on similar cars.

Anti-roll bar linkage ball joints (front)

Failed on 60 first tests2.1 times as often as similar carsPossible evidence

What it means

Excessive wear on an anti-roll bar linkage ball joint is Major. A joint likely to become detached is graded Dangerous.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Brakes

Four faults. The strongest is the brake hand lever: 4.2 times as often as on similar cars.

Brake hand lever

Failed on 20 first tests4.2 times as often as similar carsPossible evidence

What it means

A brake lever is failed for insufficient reserve only if it is touching the floor or handlebar. On motorcycle derived systems the lever may touch the handlebar, so the extent of reserve travel is assessed during the brake test. A lever not releasing correctly is Minor, and Major where the functionality of the brakes is affected.

Flexible brake hoses (front)

Failed on 53 first tests3.9 times as often as similar carsLikely evidence

What it means

Testers reject a flexible brake hose for being excessively damaged or chafed only if it is severe enough to expose the reinforcement. Slight damage, chafing or twisting is graded Minor. A leak is graded Dangerous on a hydraulic braking system and Major on an air system, and a hose damaged and likely to fail is also Dangerous.

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

Failed on 43 first tests3.1 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.

Handbrake lever

Failed on 22 first tests2.6 times as often as similar carsPossible evidence

What it means

A parking brake lever pivot or ratchet mechanism that is obviously worn is graded Minor. It is Major when worn to the extent that the brake may inadvertently release, and also when the ratchet is not holding correctly. A lever must have obvious excessive travel before being rejected.

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

Steering

One fault: track rod end, 2.4 times as often as on similar cars.

Track rod end

Failed on 35 first tests2.4 times as often as similar carsPossible 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.

MOT pass rates

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

Passed first time
49in every 100
Passed on the first test.

FAQs

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

The 2006 SEAT Ibiza follows the pattern of the model years either side. Its main cause of failure was Individual sidelight or tail light (front), about 16 in every 100 failed tests. In 2025, 49.4% of 1,968 first MOTs on the 2006 SEAT Ibiza passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 60.0%. Among 995 failed first-attempt MOT tests (test year 2025), Body panel (front) appears more often than on similar cars (2.2% of those tests; 22 observed failures; about 12× 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 SEAT Ibiza at the first attempt were Individual sidelight or tail light (front) (15.6%), Windscreen washers (11.5%) and Brake light (10.7%), 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: Body panel (front) (2.2% of those tests; 22 observed failures; about 12× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Body panel (front) shows up more often than on similar cars (2.2% of those tests; 22 observed failures; about 12× 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 SEAT Ibiza include Body panel (front), Suspension arm (front), Brake hand lever. These are the faults that stand out compared with similar cars, not a complete list of what can go wrong on any individual car.
This page highlights MOT failure patterns for the 2006 SEAT Ibiza (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.
