Peugeot Boxer 2016: reliability & common MOT faults

679 first-attempt MOT failures were recorded on the 2016 Peugeot Boxer in 2025. Figures are among first-attempt failed MOT tests, not among all tests.

Rbt (sp) was the most common reason a 2016 Boxer failed its MOT — 17.2% of its failed first attempts.

Note:

  • Class 4 cars · first MOT of the year per vehicle · P/PRS/F outcomes (2025 data).
  • PRS (fixed at the station the same day) counts as a fail in the first-attempt rate.
  • Raw outcomes for this cohort — not adjusted for age, mileage, or peer mix.
  • MOT doesn't test engine or gearbox internals.

Common faults

Failure patterns that show up more often on this registration year than on similar cars.

These MOT failure patterns show up more often on this registration year than on similar cars of the same class, age, and mileage.

Shares below are measured across the 679 failed first attempts in 2025 that the age-and-mileage comparison can be computed on.

Standout: Rbt (sp) — 17.2% of this year's failed first attempts

Recorded on 117 of those tests. It tops the table on elevation — about 5.8× more often than on similar cars of the same age and mileage. On this year it is also the commonest failure, so it answers both questions at once. The full ranked list is in the table below.

Fault pattern Location Failures vs similar cars Share of fails Confidence
SRS malfunction indicator lamp
Seat belts and supplementary restraint systems > SRS malfunction indicator lamp
 Any 40 ×6.1 5.9% Likely
Rbt (sp)
Brakes > Brake performance > Parking brake efficiency (sp) > Rbt (sp)
 Any 117 ×5.8 17.2% Strong
Rear fog lamp
Lamps, reflectors and electrical equipment > Front and rear fog lamps > Rear fog lamp > Rear fog lamp
 Any 22 ×3.7 3.2% Possible
Service brake performance (rear)
Brakes > Brake performance > Service brake performance > Rbt > Service brake performance
 Rear 25 ×2.2 3.7% Possible
Side repeaters
Lamps, reflectors and electrical equipment > Direction indicators > Flashing type > Side repeaters
 Any 20 ×2.1 2.9% Possible

Only patterns that clear minimum sample and elevation thresholds are shown (at least 20 failures and about 2.0× more often than similar cars).

Note: Rates and comparisons are among first-attempt failed tests, not all MOTs. Patterns come from MOT defect codes — not manufacturer service bulletins, recalls, or a diagnosis of any individual car. Failures and advisories are listed separately.

Advisories

Advisory notes recorded on failed first-attempt tests that appear more often than on similar cars.

Advisory pattern Location Notes vs similar cars Share Confidence
Engine oil leaks

 Any 69 ×2.3 10.2% Elevated
Note: Advisories are not a fail rate — they flag issues noted at the test, often before they become failures.

If you are buying one

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

Nothing separates this year from the Boxers either side of it, so buy on the individual car. The checks below are the items that actually failed 2016 Boxers, commonest first.

What to check on a 2016 Boxer

The items that failed 2016 Boxers most often, as a share of the year's failed first attempts. This is what goes wrong, not what is unusual — the table further up the page covers that.

  • Rbt (sp) — recorded on 17.2% of failed first attempts
  • Headlamp aim — recorded on 7.5% of failed first attempts

Every figure here is a first-attempt MOT rate from DVSA open data for this model line. 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.

Rbt (sp) was the most common reason a 2016 Boxer failed its MOT — 17.2% of its failed first attempts. In 2025, 78.4% of 3,149 first MOTs on the 2016 Peugeot Boxer passed first time (PRS — items fixed at the station the same day — counted as a fail). The official-style rate including PRS is 83.8%. Among 679 failed first-attempt MOT tests (test year 2025), Rbt (sp) appears more often than on similar cars (17.2% of tho…
Ranked by how often they were actually recorded, the items that failed 2016 Peugeot Boxers most often at the first attempt were Rbt (sp) (17.2%) and Headlamp aim (7.5%) — each as a share of the year's failed first attempts. That is what goes wrong on the car. It is a different question from which patterns are unusual for the class, which the common-faults table answers.
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Rbt (sp) (17.2% of those tests; 117 observed failures; about 5.8× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Rbt (sp) shows up more often than on similar cars (17.2% of those tests; 117 observed failures; about 5.8× 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 check point, not a manufacturer service bulletin.
Common MOT problem areas for the 2016 Peugeot Boxer include Rbt (sp), SRS malfunction indicator lamp, Rear fog lamp. These patterns show up more often than on similar cars after we filter out sparse noise — not a full list of every possible fault on an 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 2016 Peugeot Boxer (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.
  • We never invent pass rates, star scores, or ranks when those data marts are missing.
