Renault Trafic 2003: reliability & common MOT faults

In 2025, 46 in every 100 first MOTs on a 2003 Renault Trafic were passes. Most common reason for a fail: Handbrake efficiency below minimum (roller test).

Summary

The 2003 Renault Trafic follows the pattern of the model years either side.

  2. Suspension arm ball joint (front)17 in every 100 failed tests
  3. Windscreen washers16 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 2003 Renault Trafic 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 hazard warning switch: 16 times as often as on similar cars.

Figures below are measured across the 572 of 582 failed first attempts (98.3%) 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.

Hazard warning switch

Failed on 29 first tests16 times as often as similar carsPossible evidence

What it means

A hazard warning switch that is inoperative is Major, while one that is faulty or insecure is Minor. The lamps must work from one switch only, with the engine or ignition switch both on and off.

Horn

Failed on 27 first tests2.3 times as often as similar carsPossible evidence

What it means

A horn that does not work, or is likely to be confused with an emergency vehicle siren, is graded Major. Gongs, bells, sirens and anything with more than one tone, which includes a horn that alternates between its notes, are not allowed, except a gong, bell or siren on vehicles first used before a set date. Sound defects are Minor for named cases such as a bell or harsh sound, and Major under a general row.

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

Brakes

Two faults. The strongest is the brake efficiency below minimum (roller test): 3.7 times as often as on similar cars.

Brake efficiency below minimum (roller test)

Failed on 45 first tests3.7 times as often as similar carsLikely evidence

What it means

Service brake efficiency below the minimum requirement is Major, and efficiency less than half of the required value is graded Dangerous. On a roller brake tester, if more than half of the wheels of a brake system lock, the efficiency requirement for that system counts as met.

Handbrake performance (roller test)

Failed on 23 first tests2.4 times as often as similar carsPossible evidence

What it means

A parking brake that is inoperative on one side is Major. When tested on the road, the failure is the vehicle deviating excessively from a straight line. Vehicles whose parking brake was already tested as the secondary brake are not tested again for this.

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

Suspension

Three faults. The strongest is the suspension mounting area (front): 3.7 times as often as on similar cars.

Suspension mounting area (front)

Failed on 38 first tests3.7 times as often as similar carsLikely 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 22 first tests, 3.9 times as often as on similar cars.

Shock absorbers (front)

Failed on 37 first tests3.2 times as often as similar carsLikely evidence

What it means

Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 69 first tests, 3.0 times as often as on similar cars.

Suspension arm ball joint (front)

Failed on 99 first tests2.6 times as often as similar carsPossible evidence

What it means

A suspension arm ball joint is failed under the general suspension pin, bush or joint wording. Excessively worn is Major, and 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.

Body and structure

One fault: chassis condition (front), 3.4 times as often as on similar cars.

Chassis condition (front)

Failed on 26 first tests3.4 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.

Visibility

One fault: windscreen washers, 2.7 times as often as on similar cars.

Windscreen washers

Failed on 92 first tests2.7 times as often as similar carsPossible evidence

What it means

Windscreen washers that are not working, or do not provide sufficient fluid to clear the windscreen, are graded Major. They must provide enough fluid for the wipers to clear the windscreen effectively. Vehicles with an opening windscreen, or some other adequate view to the front, left and right, are not inspected for washers.

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

Seat belts and restraints

One fault: airbag warning light, 2.3 times as often as on similar cars.

Airbag warning light

Failed on 45 first tests2.3 times as often as similar carsPossible evidence

What it means

The airbag warning lamp (SRS MIL in DVSA's wording) is failed only if it indicates a system malfunction, which is Major. A lamp lit to show the passenger airbag is disabled is not to be regarded as a defect. Dashboard messages are not a defect in their own right, though they can help the tester confirm a malfunction.

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.

FAQs

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

The 2003 Renault Trafic follows the pattern of the model years either side. Its main cause of failure was Handbrake efficiency below minimum (roller test), about 21 in every 100 failed tests. In 2025, 46.2% of 1,082 first MOTs on the 2003 Renault Trafic passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 54.2%. Among 582 failed first-attempt MOT tests (test year 2025), Hazard warning switch appears more often than on similar cars (5.1% of those tests; 29 observed failures; about 16× 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 2003 Renault Trafic at the first attempt were Handbrake efficiency below minimum (roller test) (21.3%), Suspension arm ball joint (front) (17.3%) and Windscreen washers (16.1%), 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: Hazard warning switch (5.1% of those tests; 29 observed failures; about 16× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Hazard warning switch shows up more often than on similar cars (5.1% of those tests; 29 observed failures; about 16× 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 2003 Renault Trafic include Hazard warning switch, Brake efficiency below minimum (roller test), Suspension 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 2003 Renault Trafic (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.
