Peugeot 407 2010: reliability & common MOT faults

In 2025, 53 in every 100 first MOTs on a 2010 Peugeot 407 were passes. Most common reason for a fail: Drive shaft joints and boots (front).

Summary

With 889 first tests, there are too few to say whether the 2010 Peugeot 407 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 2010 Peugeot 407 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.

Steering

One fault: steering rack (front), 13 times as often as on similar cars.

Figures below are measured across the 418 of 421 failed first attempts (99.3%) 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.

Steering rack (front)

Failed on 24 first tests13 times as often as similar carsPossible evidence

What it means

Steering gear casing retaining devices dangerously loose, or visible relative movement to the chassis or bodywork, is graded Dangerous. A casing not properly attached, or fractured, is Major, but a fracture that affects the stability or attachment of the casing is Dangerous. A gaiter damaged but still keeping dirt out is Minor, and Major once missing or no longer doing so.

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

Noise, emissions and leaks

One fault: diesel emissions test (compression-ignition rules for vehicles from 01/07/2008), 5.9 times as often as on similar cars.

Body and structure

One fault: drive shaft joints and boots (front), 5.2 times as often as on similar cars.

Drive shaft joints and boots (front)

Failed on 124 first tests5.2 times as often as similar carsStrong evidence

What it means

A constant velocity boot that is only severely deteriorated is Minor. It is Major once it is missing, split or insecure so that it no longer prevents the ingress of dirt. A transmission joint excessively worn is Major, and graded Dangerous when it is so worn it is likely to fail.

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

Lamps and electrical

One fault: brake light (rear), 2.1 times as often as on similar cars.

Brake light (rear)

Failed on 39 first tests2.1 times as often as similar carsPossible evidence

What it means

All stop lamps missing or not working is graded Dangerous, and so is a stop lamp that stays on when the brakes are released. A stop lamp that is missing or not working is Major. On some vehicles with LED rear lamps, part of the stop lamp can go out when the rear fog lamp is lit, which is not regarded as a defect.

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.

Anti-roll bar linkage ball joints (rear)

Anti-roll bar linkage ball joints (front)

Suspension arm ball joint (front)

Data: UK MOT open data, 2025. Counts cover advisories recorded on failed first tests only, compared with cars of the same age and mileage.

MOT pass rates

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

Passed first time
53in every 100
Passed on the first test.
Fixed at the station
9in every 100
Failed, then fixed at the test station the same day.
Failed
38in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 52.6% of 889 first tests (2025): only cars that passed first time count. Official-style pass 62.3%: cars fixed at the test station also count as a pass. The 9 fixed and the 38 not fixed make the 47 in every 100 that did not pass first time.

Same model, other years

Newer cars are younger, so look for a jump rather than the climb. A year earlier (2024), when these cars were a year younger, 50 in every 100 passed first time.

FAQs

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

With 889 first tests, there are too few to say whether the 2010 Peugeot 407 differs from the model years either side. Its main cause of failure was Drive shaft joints and boots (front), about 30 in every 100 failed tests. In 2025, 52.6% of 889 first MOTs on the 2010 Peugeot 407 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 62.3%. Among 421 failed first-attempt MOT tests (test year 2025), Drive shaft joints and boots (front) appears more often than on similar cars (29.7% of those tests; 124 observed failures; about 5.2× 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 2010 Peugeot 407 at the first attempt were Drive shaft joints and boots (front) (29.7%) and Individual sidelight or tail light (front) (17.0%), 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: Drive shaft joints and boots (front) (29.7% of those tests; 124 observed failures; about 5.2× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Drive shaft joints and boots (front) shows up more often than on similar cars (29.7% of those tests; 124 observed failures; about 5.2× 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 2010 Peugeot 407 include Drive shaft joints and boots (front), Steering rack (front), Brake light (rear). 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 2010 Peugeot 407 (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.
