Peugeot 308 2014: reliability & common MOT faults

In 2025, 62 in every 100 first MOTs on a 2014 Peugeot 308 were passes. Most common reason for a fail: Track rod end (front).

Summary

The 2014 Peugeot 308 follows the pattern of the model years either side.

  2. Anti-roll bar linkage ball joint dust cover (front)13 in every 100 failed tests
  3. Drive shaft joints and boots (front)13 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 2014 Peugeot 308 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 anti-roll bar linkage ball joint dust cover (front): 5.1 times as often as on similar cars.

Figures below are measured across the 4,276 of 4,279 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 ball joint dust cover (front)

Failed on 559 first tests5.1 times as often as similar carsStrong evidence

What it means

A suspension joint dust cover that is severely deteriorated is Minor. It becomes Major once it is missing or no longer prevents the ingress of dirt, so what matters is whether it still keeps dirt out. DVSA words this for any suspension joint dust cover, and files it here under anti-roll bars.

Anti-roll bar ball joint dust cover (front)

Failed on 219 first tests5.1 times as often as similar carsStrong evidence

What it means

A missing anti-roll bar ball joint dust cover is Major, and so is one that no longer prevents the ingress of dirt. A cover that is only severely deteriorated is Minor. DVSA uses one wording for the dust cover on any suspension joint.

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 direction indicators (rear): 3.7 times as often as on similar cars.

Individual direction indicators (rear)

Failed on 119 first tests3.7 times as often as similar carsLikely evidence

What it means

Direction indicators must be amber, though vehicles first used before a set date may have white at the front and red at the rear when the indicators are combined with stop or position lamps, and sequential or dynamic ones are not a reason to fail. A lamp that is missing, inoperative or has more than half of a multiple light source not functioning is graded Major. A flashing rate outside the permitted range is graded Minor.

Number plate lights (rear)

Failed on 272 first tests2.0 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.

Body and structure

One fault: drive shaft joints and boots (front), 3.0 times as often as on similar cars.

Drive shaft joints and boots (front)

Failed on 556 first tests3.0 times as often as similar carsLikely 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.

Steering

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

Track rod end (front)

Failed on 584 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.

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.

Flexible brake hoses (rear)

Noted on 86 first tests2.8 times as often as similar carsElevated evidence

Track rod end

Noted on 34 first tests2.0 times as often as similar carsPossible evidence

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.

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

First-attempt pass 61.7% of 11,161 first tests (2025): only cars that passed first time count. Official-style pass 67.2%: cars fixed at the test station also count as a pass. The 5 fixed and the 33 not fixed make the 38 in every 100 that did not pass first time.

Petrol and diesel

First testsTypical mileagePassed first time, as testedPassed first time, same mileage
Diesel9,20892,941 miles6061
Petrol1,95364,893 miles6763

Figures are in every 100 first tests. Cars with more miles usually fail more often, so the same-mileage figure gives every fuel the mileage mix of all the cars in this year.

If you are buying one

What this year's MOT record means for the decision in front of you.

Mileage matters most on a 2014 Peugeot 308.

Of 2014 Peugeot 308 vehicles with under 62,000 miles, 70 in every 100 passed their 2025 MOT first time. With 117,000 miles or more, 57 in every 100 did.

Petrol or diesel?

Typical mileagePassed first time,
as tested		Passed first time,
same mileage
Diesel92,941 miles6161
Petrol64,893 miles6763

Figures are in every 100 first tests. Petrol cars look better on the raw figures only because diesel cars have done more miles (typically 92,941 against 64,893). At the same mileage there is no clear difference between the two.

What to check at your mileage

How often each fault turned up on a failed first test, by the car's mileage. Read it as: what is likely to need looking at on a car like the one in front of you.

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 2014 Peugeot 308 follows the pattern of the model years either side. Its main cause of failure was Track rod end (front), about 14 in every 100 failed tests. In 2025, 61.7% of 11,161 first MOTs on the 2014 Peugeot 308 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 67.2%. Among 4,279 failed first-attempt MOT tests (test year 2025), Anti-roll bar linkage ball joint dust cover (front) appears more often than on similar cars (13.1% of those tests; 559 observed failures; about 5.1× 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 2014 Peugeot 308 at the first attempt were Track rod end (front) (13.7%), Anti-roll bar linkage ball joint dust cover (front) (13.1%) and Drive shaft joints and boots (front) (13.0%), 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: Anti-roll bar linkage ball joint dust cover (front) (13.1% of those tests; 559 observed failures; about 5.1× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Anti-roll bar linkage ball joint dust cover (front) shows up more often than on similar cars (13.1% of those tests; 559 observed failures; about 5.1× 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 2014 Peugeot 308 include Anti-roll bar linkage ball joint dust cover (front), Anti-roll bar ball joint dust cover (front), Individual direction indicators (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 2014 Peugeot 308 (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.
