Peugeot 3008 2020: reliability & common MOT faults

In 2025, 86 in every 100 first MOTs on a 2020 Peugeot 3008 were passes. Most common reason for a fail: Tyre condition (rear).

Summary

The 2020 Peugeot 3008 follows the pattern of the model years either side.

What failed most often

  1. Tyre condition (rear)13 in every 100 failed tests
  2. Brake pads (rear)13 in every 100 failed tests
  3. Tyre tread depth (front)11 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 2020 Peugeot 3008 vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.

Tyres

One wear pattern: tyre tread depth (rear), 2.8 times as often as on similar cars.

Figures below are measured across the 1,549 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.

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.

Tyre tread depth (rear)

Failed on 143 first tests2.8 times as often as similar carsWear pattern

What it means

Only primary grooves count when tread depth is assessed: those holding the wear indicators, or cut as deep as those when new. Shallower secondary grooves are ignored. Tread depth below the minimum for the vehicle is Dangerous, and so is a pattern not visible over the whole tread, but that second row applies only to vehicles that need the lower minimum.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 310 first tests, 2.1 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.

Body and structure

One fault: drive shaft joints and boots (front), 2.7 times as often as on similar cars.

Drive shaft joints and boots (front)

Failed on 44 first tests2.7 times as often as similar carsPossible 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.

Suspension

One fault: coil spring (rear), 2.4 times as often as on similar cars.

Coil spring (rear)

Failed on 54 first tests2.4 times as often as similar carsPossible evidence

What it means

A missing bump stop rubber is not a reason to fail a coil spring. When the vehicle is jacked and lowered, a spring that does not correctly locate as the suspension returns to its normal running position is rejected as insecurely attached. A missing spring is Major, and graded Dangerous where directional control is affected.

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

Brakes

One wear pattern: brake pads (rear), 2.0 times as often as on similar cars.

Brake pads (rear)

Failed on 202 first tests2.0 times as often as similar carsWear pattern

What it means

A pad worn down to its wear indicator, or contaminated with oil or grease, is Major. A pad worn below the set thickness limit, missing or incorrectly mounted is Dangerous. The manual treats an illuminated brake wear indicator as no reason for failure, although DVSA also lists an illuminated indicator as a Major row.

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.

Exhaust system (rear)

Noted on 36 first tests22 times as often as similar carsElevated 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.

Passed first time
86in every 100
Passed on the first test.
Fixed at the station
3in every 100
Failed, then fixed at the test station the same day.
Failed
11in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 86.0% of 11,065 first tests (2025): only cars that passed first time count. Official-style pass 88.6%: cars fixed at the test station also count as a pass. The 3 fixed and the 11 not fixed make the 14 in every 100 that did not pass first time.

By fuel type

Petrol6,57134,990 miles8686
Diesel3,49743,398 miles8687
Hybrid99740,074 miles8585

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.

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 2020 Peugeot 3008 follows the pattern of the model years either side. Its main cause of failure was Tyre condition (rear), about 13 in every 100 failed tests. In 2025, 86.0% of 11,065 first MOTs on the 2020 Peugeot 3008 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 88.6%. Among 1,549 failed first-attempt MOT tests (test year 2025), Drive shaft joints and boots (front) appears more often than on similar cars (2.8% of those tests; 44 observed failures; about 2.7× 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 2020 Peugeot 3008 at the first attempt were Tyre condition (rear) (13.5%), Brake pads (rear) (13.0%) and Tyre tread depth (front) (10.8%), 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: Drive shaft joints and boots (front) (2.8% of those tests; 44 observed failures; about 2.7× 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 (2.8% of those tests; 44 observed failures; about 2.7× 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 2020 Peugeot 3008 include Drive shaft joints and boots (front), Coil spring (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 2020 Peugeot 3008 (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.
