BMW iX 2022: reliability & common MOT faults

In 2025, 85 in every 100 first MOTs on a 2022 BMW iX were passes. Most common reason for a fail: Tyre condition (rear).

Summary

The 2022 BMW iX follows the pattern of the model years either side.

  2. Tyre tread depth (rear)15 in every 100 failed tests
  3. Windscreen wipers (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 2022 BMW iX 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.

Steering

One fault: track rod end (front), 17 times as often as on similar cars.

Figures below are measured across the 711 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.

Track rod end (front)

Failed on 52 first tests17 times as often as similar carsLikely 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.

Tyres

Two wear patterns. The strongest is the tyre tread depth (rear): 4.2 times as often as on similar cars.

Tyre tread depth (rear)

Failed on 106 first tests4.2 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 165 first tests, 2.4 times as often as on similar cars.

Tyre condition (rear)

Failed on 255 first tests2.1 times as often as similar carsWear pattern

What it means

Exposed or damaged ply or cords are graded Dangerous. A cut in excess of the requirements and deep enough to reach the ply or cords is Major, and testers may open the cut with a blunt instrument to check its depth. A tyre contacting the vehicle through flexing or suspension movement is not a defect; fouling fails only at the time of test.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Number plates and VIN

One fault: number plates (front), 2.1 times as often as on similar cars.

Number plates (front)

Failed on 20 first tests2.1 times as often as similar carsPossible evidence

What it means

A number plate that is missing, illegible, showing an incorrect registration or so insecure that it is likely to fall off is Major. Testers do not measure the characters or their spacing and reject them only if they are obviously incorrect. Delamination and the position of fixing screws or bolts get particular attention, as they can prevent number plate recognition cameras identifying the vehicle.

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

MOT pass rates

How first tests ended, and how the pass rates are counted.

First-attempt pass 85.2% of 4,792 first tests (2025): only cars that passed first time count. Official-style pass 86.7%: cars fixed at the test station also count as a pass. The 2 fixed and the 13 not fixed make the 15 in every 100 that did not pass first time.

Newer cars are younger, so look for a jump rather than the climb.

If you are buying one

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

Mileage makes a modest difference on a 2022 BMW iX.

Of 2022 BMW iX vehicles with under 19,000 miles, 90 in every 100 passed their 2025 MOT first time. With 41,000 miles or more, 82 in every 100 did.

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 2022 BMW iX follows the pattern of the model years either side. Its main cause of failure was Tyre condition (rear), about 36 in every 100 failed tests. In 2025, 85.2% of 4,792 first MOTs on the 2022 BMW iX passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 86.7%. Among 711 failed first-attempt MOT tests (test year 2025), Track rod end (front) appears more often than on similar cars (7.3% of those tests; 52 observed failures; about 17× 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 BMW iX at the first attempt were Tyre condition (rear) (35.9%), Tyre tread depth (rear) (14.9%) and Windscreen wipers (front) (10.7%), 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: Track rod end (front) (7.3% of those tests; 52 observed failures; about 17× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Track rod end (front) shows up more often than on similar cars (7.3% of those tests; 52 observed failures; about 17× 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 BMW iX include Track rod end (front), Number plates (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 BMW iX (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.
