Mitsubishi Colt 2007: reliability & common MOT faults

In 2025, 49 in every 100 first MOTs on a 2007 Mitsubishi Colt were passes. Most common reason for a fail: Individual sidelight or tail light (front).

Summary

The 2007 Mitsubishi Colt follows the pattern of the model years either side.

  2. Headlight aim12 in every 100 failed tests
  3. Drive shaft joints and boots (front)12 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 2007 Mitsubishi Colt 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 anti-roll bar linkage (front): 14 times as often as on similar cars.

Figures below are measured across the 1,364 of 1,365 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.

Anti-roll bar linkage (front)

Failed on 63 first tests14 times as often as similar carsLikely evidence

What it means

An anti-roll bar linkage is graded Dangerous when a suspension component is missing, likely to become detached, fractured or likely to fail. Insecure attachment that impairs directional stability is graded Dangerous too. Excessive damage or corrosion that seriously weakens the part is Major, and so is plain insecure attachment to the chassis or axle.

Anti-roll bar linkage pins and bushes (front)

Failed on 62 first tests12 times as often as similar carsLikely evidence

What it means

Excessive wear in an anti-roll bar linkage pin or bush is Major. If the pin or bush is likely to become detached, it is graded Dangerous. The wording is DVSA's general one for a suspension pin, bush or joint.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 59 first tests, 5.4 times as often as on similar cars.

Suspension arm ball joint dust cover (front)

Failed on 85 first tests2.9 times as often as similar carsPossible evidence

What it means

Whether a suspension arm ball joint dust cover still keeps dirt out decides its grade. Severely deteriorated is Minor, while missing, or no longer preventing the ingress of dirt, is Major.

Suspension mounting area (rear)

Failed on 120 first tests2.3 times as often as similar carsPossible 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 98 first tests, 2.7 times as often as on similar cars.

Wheel bearings (rear)

Failed on 37 first tests2.1 times as often as similar carsPossible evidence

What it means

Excessive play in a wheel bearing, or a bearing that is excessively rough, is Major. Play so excessive that the bearing is likely to break up or directional control is impaired is Dangerous, and so is a bearing so rough that it is likely to overheat or break up.

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), 2.4 times as often as on similar cars.

Track rod end (front)

Failed on 123 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.

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

Body and structure

One fault: chassis condition (rear), 2.1 times as often as on similar cars.

Chassis condition (rear)

Failed on 29 first tests2.1 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.

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.

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

First-attempt pass 49.3% of 2,691 first tests (2025): only cars that passed first time count. Official-style pass 60.0%: cars fixed at the test station also count as a pass. The 11 fixed and the 40 not fixed make the 51 in every 100 that did not pass first time.

Petrol and diesel

Every figure here is a first-attempt MOT rate from DVSA open data for this model line, for cars of this model year tested in 2025. Each mileage band holds a fifth of the tests. MOTs do not test engine or gearbox internals, so this is a pre-purchase checklist, not a full reliability score.

FAQs

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

The 2007 Mitsubishi Colt follows the pattern of the model years either side. Its main cause of failure was Individual sidelight or tail light (front), about 14 in every 100 failed tests. In 2025, 49.3% of 2,691 first MOTs on the 2007 Mitsubishi Colt 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 1,365 failed first-attempt MOT tests (test year 2025), Anti-roll bar linkage (front) appears more often than on similar cars (4.6% of those tests; 63 observed failures; about 14× 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 2007 Mitsubishi Colt at the first attempt were Individual sidelight or tail light (front) (14.3%), Headlight aim (12.4%) and Drive shaft joints and boots (front) (11.8%), 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: Anti-roll bar linkage (front) (4.6% of those tests; 63 observed failures; about 14× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Anti-roll bar linkage (front) shows up more often than on similar cars (4.6% of those tests; 63 observed failures; about 14× 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 2007 Mitsubishi Colt include Anti-roll bar linkage (front), Anti-roll bar linkage pins and bushes (front), Suspension arm ball joint dust cover (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 2007 Mitsubishi Colt (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.
