Kia Stonic 2022: reliability & common MOT faults

In 2025, 91 in every 100 first MOTs on a 2022 Kia Stonic were passes. Most common reason for a fail: Tyre condition (front).

Summary

The 2022 Kia Stonic follows the pattern of the model years either side.

  2. Windscreen wipers (front)13 in every 100 failed tests
  3. Brake pads (front)10 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 2022 Kia Stonic 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.

Noise, emissions and leaks

One fault: petrol emissions (with catalyst), 12 times as often as on similar cars.

Figures below are measured across the 499 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.

Petrol emissions (with catalyst)

Failed on 21 first tests12 times as often as similar carsPossible evidence

What it means

Emissions levels over the manufacturer's specified limits are Major, as are levels over default limits, which apply when no exact match is found for the vehicle. Dense blue or clearly visible black smoke at idle, held for a set period, is Major, except for certain older vehicles and two stroke engines where smoke is unavoidable. An induction or exhaust leak that could affect emissions levels is Major too.

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

Brakes

One wear pattern: brake pads (front), 2.8 times as often as on similar cars.

Brake pads (front)

Failed on 52 first tests2.8 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.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 58 first tests, 2.3 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.

Visibility

One fault: windscreen washers (front), 2.5 times as often as on similar cars.

Windscreen washers (front)

Failed on 36 first tests2.5 times as often as similar carsPossible evidence

What it means

Windscreen washers that are not working, or do not provide sufficient fluid to clear the windscreen, are graded Major. They must provide enough fluid for the wipers to clear the windscreen effectively. Vehicles with an opening windscreen, or some other adequate view to the front, left and right, are not inspected for washers.

First-attempt pass 91.3% of 5,754 first tests (2025): only cars that passed first time count. Official-style pass 93.9%: cars fixed at the test station also count as a pass. The 3 fixed and the 6 not fixed make the 9 in every 100 that did not pass first time.

By fuel type

If you are buying one

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

Mileage matters most on a 2022 Stonic.

Of 2022 Stonic vehicles with under 12,000 miles, 96 in every 100 passed their 2025 MOT first time. With 31,000 miles or more, 84 in every 100 did.

same mileage
Hybrid19,695 miles9393
Petrol21,250 miles8888

Figures are in every 100 first tests. Hybrid cars look better on the raw figures only because petrol cars have done more miles (typically 21,250 against 19,695). 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.

Tyre condition (front)0.51.32.4
Windscreen wipers (front)0.61.22.2
Brake pads (front)0.00.62.6

Faults per 100 first tests, by the car's mileage at the test.

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 2022 Kia Stonic follows the pattern of the model years either side. Its main cause of failure was Tyre condition (front), about 16 in every 100 failed tests. In 2025, 91.3% of 5,754 first MOTs on the 2022 Kia Stonic passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 93.9%. Among 499 failed first-attempt MOT tests (test year 2025), Petrol emissions (with catalyst) appears more often than on similar cars (4.2% of those tests; 21 observed failures; about 12× 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 2022 Kia Stonic at the first attempt were Tyre condition (front) (15.8%), Windscreen wipers (front) (12.8%) and Brake pads (front) (10.4%), 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: Petrol emissions (with catalyst) (4.2% of those tests; 21 observed failures; about 12× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Petrol emissions (with catalyst) shows up more often than on similar cars (4.2% of those tests; 21 observed failures; about 12× 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 2022 Kia Stonic include Petrol emissions (with catalyst), Windscreen washers (front). These are the faults that stand out compared with similar cars, not a complete list of what can go wrong on any individual car.
This page highlights MOT failure patterns for the 2022 Kia Stonic (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.
