Nissan Primastar 2005: reliability & common MOT faults

In 2025, 46 in every 100 first MOTs on a 2005 Nissan Primastar were passes. Most common reason for a fail: Suspension arm ball joint (front).

Summary

With 755 first tests, there are too few to say whether the 2005 Nissan Primastar differs from the model years either side.

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 2005 Nissan Primastar 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

Two faults. The strongest is the suspension mounting area (front): 3.8 times as often as on similar cars.

Figures below are measured across the 404 of 406 failed first attempts (99.5%) 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 mounting area (front)

Failed on 22 first tests3.8 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.

Suspension arm ball joint (front)

Failed on 86 first tests3.2 times as often as similar carsLikely 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.

Brakes

Two faults. The strongest is the handbrake performance (roller test): 3.0 times as often as on similar cars.

Handbrake performance (roller test)

Failed on 20 first tests3.0 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.

Anti-lock braking system (ABS)

Failed on 32 first tests2.2 times as often as similar carsPossible evidence

What it means

ABS is failed as removed only where it has obviously been removed, because not every vehicle in the age range where removal is not permitted has ABS. A warning lamp that does not light or shows an ABS fault is Major, as is a missing or excessively damaged wheel speed sensor. Every failure row for this component is Major.

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

Lamps and electrical

Two faults. The strongest is the individual sidelight or tail light (rear): 2.8 times as often as on similar cars.

Individual sidelight or tail light (rear)

Failed on 35 first tests2.8 times as often as similar carsPossible evidence

What it means

A position lamp showing red light to the front or white light to the rear is Major. Rear lamps must show a steady red light, and front ones can show white, predominantly white with a blue tinge, or yellow if combined in a yellow headlamp. With a multiple light source, up to half not working is Minor and more than half is Major.

Number plate lights

Failed on 33 first tests2.1 times as often as similar carsPossible evidence

What it means

Registration plate lamps must light up the rear registration plate and operate at the same time as the position lamps. A missing or inoperative lamp is Major when the plate has only one lamp or all its lamps are not working, and Minor when the plate has several lamps or light sources and not all have failed. A lamp throwing direct white light to the rear is also Minor.

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

Steering

One fault: track rod end (front), 2.5 times as often as on similar cars.

Track rod end (front)

Failed on 50 first tests2.5 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.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 27 first tests, 3.2 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.

With 755 first tests, there are too few to say whether the 2005 Nissan Primastar differs from the model years either side. Its main cause of failure was Suspension arm ball joint (front), about 21 in every 100 failed tests. In 2025, 46.2% of 755 first MOTs on the 2005 Nissan Primastar passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 55.2%. Among 406 failed first-attempt MOT tests (test year 2025), Suspension mounting area (front) appears more often than on similar cars (5.4% of those tests; 22 observed failures; about 3.8× 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 2005 Nissan Primastar at the first attempt were Suspension arm ball joint (front) (21.3%), Handbrake efficiency below minimum (roller test) (19.3%) and Individual sidelight or tail light (front) (15.3%), 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) (5.4% of those tests; 22 observed failures; about 3.8× 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 (5.4% of those tests; 22 observed failures; about 3.8× 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 2005 Nissan Primastar include Suspension mounting area (front), Suspension arm ball joint (front), Handbrake performance (roller test). 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 2005 Nissan Primastar (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.
