MINI Countryman 2021: reliability & common MOT faults

735 first-attempt MOT failures were recorded on the 2021 MINI Countryman in 2025. Figures are among first-attempt failed MOT tests, not among all tests.

Tyres — Condition (rear) was the most common reason a 2021 Countryman failed its MOT — 29.4% 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.

Wear patterns

Usage and mileage effects that often track road use rather than model design.

These patterns look like wear or usage effects rather than model-specific design faults. Tyres, brake friction material, and alignment-related defects often track mileage and road use.

Pattern Location Failures vs similar cars Share of fails Confidence

Tyres > Condition
 Rear 216 ×2.2 29.4% Wear

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 Countrymans either side of it, so buy on the individual car. The checks below are the items that actually failed 2021 Countrymans, commonest first.

Other Countryman years worth knowing about

Newer cars always pass more often, so a plain "best year" list would just rank by age. These are the years that beat or miss the trend their own neighbouring years set — the only age-adjusted signal this data supports.

Year vs the years either side First-attempt pass (rises with newer cars) First tests
2023 Countryman +3.4 pp better 94.0% 513
2017 Countryman +1.4 pp better 85.9% 10,567
2018 Countryman -1.6 pp worse 85.5% 13,277

What to check on a 2021 Countryman

The items that failed 2021 Countrymans 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.

  • Tyres — Condition (rear) — recorded on 29.4% of failed first attempts
  • Visibility — Wipers (front) — recorded on 19.0% 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.

Tyres — Condition (rear) was the most common reason a 2021 Countryman failed its MOT — 29.4% of its failed first attempts. In 2025, 89.6% of 7,080 first MOTs on the 2021 MINI Countryman passed first time (PRS — items fixed at the station the same day — counted as a fail). The official-style rate including PRS is 91.8%. Among 735 failed first-attempt MOT tests (test year 2025), we highlight MOT failure patterns that…
Ranked by how often they were actually recorded, the items that failed 2021 MINI Countrymans most often at the first attempt were Tyres — Condition (rear) (29.4%) and Visibility — Wipers (front) (19.0%) — 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.
This page highlights MOT failure patterns for the 2021 MINI Countryman (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.
