Ford Ka 2006: reliability & common MOT faults

In 2025, 49 in every 100 first MOTs on a 2006 Ford Ka were passes. Most common reason for a fail: Suspension mounting area (rear).

Summary

The 2006 Ford Ka follows the pattern of the model years either side.

  1. Suspension mounting area (rear)22 in every 100 failed tests
  2. Suspension arm pins and bushes (front)13 in every 100 failed tests
  3. Tyre condition (front)9 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 Ford Ka 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.

Suspension

Five faults. The strongest is the suspension sub-frame mounting area (front): 20 times as often as on similar cars.

Figures below are measured across the 1,002 of 1,003 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.

Suspension sub-frame mounting area (front)

Failed on 49 first tests20 times as often as similar carsLikely evidence

What it means

Structure around a sub-frame mounting that is so weakened that control of the vehicle is likely to be adversely affected is graded Dangerous, whether it is damaged, fractured, corroded or inadequately repaired. It is Major when strength is significantly reduced by excessive corrosion, damage or a fracture, or when it is inadequately repaired.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 69 first tests, 13 times as often as on similar cars.

Suspension mounting area (front)

Failed on 103 first tests10 times as often as similar carsStrong evidence

What it means

The load bearing structure within a set distance of a sub-frame, spring or suspension component mounting is a prescribed area. Major applies when its strength or continuity is significantly reduced or it is inadequately repaired. Dangerous applies when it is so weakened that control of the vehicle is likely to be adversely affected.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 89 first tests, 14 times as often as on similar cars.

Swivel pins and bushes (rear)

Failed on 28 first tests7.7 times as often as similar carsPossible evidence

What it means

A stub axle swivel pin or bush that is excessively worn is Major. One that is insecure, or so worn or insecure that directional stability is impaired, is graded Dangerous.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 41 first tests, 3.8 times as often as on similar cars.

Suspension mounting area (rear)

Failed on 220 first tests6.2 times as often as similar carsStrong evidence

What it means

The load bearing structure within a set distance of a sub-frame, spring or suspension component mounting is a prescribed area. Major applies when its strength or continuity is significantly reduced or it is inadequately repaired. Dangerous applies when it is so weakened that control of the vehicle is likely to be adversely affected.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 90 first tests, 4.0 times as often as on similar cars.

Suspension arm pins and bushes (front)

Failed on 134 first tests4.0 times as often as similar carsLikely 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 188 first tests, 2.9 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.

Seat belts and restraints

One fault: seat belt mounting area (front), 9.9 times as often as on similar cars.

Seat belt mounting area (front)

Failed on 40 first tests9.9 times as often as similar carsLikely evidence

What it means

A seat belt anchorage likely to become detached in the event of a collision is graded Dangerous. The load bearing structure near an anchorage, called a prescribed area, is Major when its strength or continuity is significantly reduced or it is inadequately repaired. Anchorage points are inspected for all seat belts fitted, except a belt with no corresponding seat.

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

Body and structure

Four faults. The strongest is the chassis condition (front): 8.9 times as often as on similar cars.

Chassis condition (front)

Failed on 52 first tests8.9 times as often as similar carsLikely 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 34 first tests, 6.5 times as often as on similar cars.

Vehicle structure condition (front)

Failed on 32 first tests6.4 times as often as similar carsLikely evidence

What it means

Structure that is fractured, deformed, corroded, modified or inadequately repaired is failed on rigidity only if the overall structural rigidity of the vehicle is significantly reduced. Structure that is likely to affect steering or braking adversely is graded Dangerous. Prescribed areas are not covered here, as they are checked under other sections, including brakes and steering.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 29 first tests, 6.6 times as often as on similar cars.

Vehicle structure condition (rear)

Failed on 44 first tests6.2 times as often as similar carsLikely evidence

What it means

Structure that is fractured, deformed, corroded, modified or inadequately repaired is failed on rigidity only if the overall structural rigidity of the vehicle is significantly reduced. Structure that is likely to affect steering or braking adversely is graded Dangerous. Prescribed areas are not covered here, as they are checked under other sections, including brakes and steering.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 23 first tests, 3.6 times as often as on similar cars.

Chassis condition (rear)

Failed on 54 first tests5.7 times as often as similar carsLikely 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 20 first tests, 2.4 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.

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.

FAQs

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

The 2006 Ford Ka follows the pattern of the model years either side. Its main cause of failure was Suspension mounting area (rear), about 22 in every 100 failed tests. In 2025, 49.4% of 1,983 first MOTs on the 2006 Ford Ka passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 56.1%. Among 1,003 failed first-attempt MOT tests (test year 2025), Suspension mounting area (front) appears more often than on similar cars (10.3% of those tests; 103 observed failures; about 10× 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 Ford Ka at the first attempt were Suspension mounting area (rear) (22.0%), Suspension arm pins and bushes (front) (13.4%) and Tyre condition (front) (8.8%), 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 mounting area (front) (10.3% of those tests; 103 observed failures; about 10× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Suspension mounting area (front) shows up more often than on similar cars (10.3% of those tests; 103 observed failures; about 10× 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 Ford Ka include Suspension mounting area (front), Suspension sub-frame mounting area (front), Seat belt mounting area (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 Ford Ka (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.
