Lexus UX 2022: reliability & common MOT faults

At a glance

How 3,330 first tests went in 2025.

Passed first time: 95 in every 100
Did not pass first time: 5 in every 100176 failed first-attempt tests
The typical car: 3 yearsabout 20,678 miles
First tests counted: 3,330

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 Lexus UX 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.

Lamps and electrical

One wear pattern: headlight aim (front), 3.0 times as often as on similar cars.

Figures below are measured across the 176 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.

Headlight aim (front)

Failed on 28 first tests3.0 times as often as similar carsWear pattern

What it means

Beam aim too high, too low or off to either side is Major. Where a driver's beam aim control is fitted, the aim is tested without altering the setting, and rechecked at the highest setting only if it would fail for being too low. Masks or converter kits on right hand dip headlamps are acceptable.

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.

Passed first time: 95in every 100; Passed on the first test.
Fixed at the station: 2in every 100; Failed, then fixed at the test station the same day.
Failed: 3in every 100; Did not pass, and were not fixed at the test station.

First-attempt pass 94.7% of 3,330 first tests (2025): only cars that passed first time count. Official-style pass 97.0%: cars fixed at the test station also count as a pass. The 2 fixed and the 3 not fixed make the 5 in every 100 that did not pass first time.

By fuel type

First testsTypical mileagePassed first time, as testedPassed first time, same mileage

Hybrid2,97320,665 miles9595

Electric35720,889 miles9292

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.

Same model, other years

Passed first time in every 100, all tested in 2025.

Year	Passed first time	First tests
2019	93 in every 100	3,257
2020	92 in every 100	3,688
2021	95 in every 100	5,043
2022 This car	95 in every 100	3,330

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 Lexus UX.

Of 2022 Lexus UX vehicles with under 13,000 miles, 97 in every 100 passed their 2025 MOT first time. With 30,000 miles or more, 91 in every 100 did.

Which fuel?

	Typical mileage	Passed first time, as tested	Passed first time, same mileage
Hybrid	20,665 miles	95	95
Electric	20,889 miles	92	92

Figures are in every 100 first tests. Hybrid cars look better on the raw figures only because electric cars have done more miles (typically 20,889 against 20,665). At the same mileage there is no clear difference between the two.

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.

Is the 2022 Lexus UX reliable?

The 2022 Lexus UX follows the pattern of the model years either side. In 2025, 94.7% of 3,330 first MOTs on the 2022 Lexus UX passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 97.0%. Among 176 failed first-attempt MOT tests (test year 2025), we highlight MOT failure patterns that show up more often than on cars of a similar age and mileage when the sample is large enough to trust. 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.

What does this Lexus UX 2022 MOT report cover?

This page highlights MOT failure patterns for the 2022 Lexus UX (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.

Does this include engine and gearbox problems?

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.
