BMW iX3 years to avoid? MOT pass rate by year

9,278 initial MOT tests in 2025 on cars first used 2021–2022 · DVSA data · For guidance only · How we count

BMW iX3 years with MOT pass rates below the average for vehicles first used in the same year: 2022. None is clearly above it. The other year can't be told apart from average.

The MOT pass rate is one signal, not the whole story. An MOT checks safety and emissions on the day of the test. It doesn't record gearbox or engine faults, and a pass rate also reflects mileage and upkeep, so the table shows median mileage too. Whatever the year, the car in front of you matters more than its model's average.

First-time pass rate, all years together: initial tests passed with no repairs. 95% range 84.6% to 86.1%.

BMW iX3 MOT pass rate by year

Year is when the car was first used. Older vehicles fail more often, so each year is compared with all vehicles first used that year.

Year	Chart	Testsmedian miles	Passed first time	Against all vehicles that year
2022age 3		6,33129,300	84.6%±1.0	−3.9 ptsall: 88.5%
2021age 4		2,94736,900	87.1%±1.3	−0.1 ptsall: 87.2%

Tests are initial MOT tests in 2025, not retests. Median miles is the middle odometer reading at the test: half had more, half had less. ± is the 95% margin of error in points (Wilson interval): a difference smaller than that could be chance. Years without a link have fewer than 10,000 tests, so they are listed here but don't have their own page.

When a car's mileage doesn't add up

Does mileage matter?

BMW iX3 first-time pass rates by the mileage at the initial test, all years together, against all vehicles of the same age and mileage.

87.5% of BMW iX3 tests under 30,000 miles passed first time, against 84.3% at 30,000 to 59,999 miles. For all vehicles of the same age and mileage, the figures are 90.9% and 85.1%.

Miles at the test	Tests	Passed first time	Against all vehicles, same age and mileage
Under 30,000	4,255	87.5%±1.1	−3.4 ptsall: 90.9%
30,000–59,999	4,326	84.3%±1.2	−0.8 ptsall: 85.1%

Against all vehicles of the same age and mileage, iX3 tests were below average under 30,000 miles and about average at 30,000 to 59,999 miles.

Mileage is only one factor. How a car has been driven and looked after matters too. These figures show an association across all BMW iX3 tests in 2025, not what mileage does to a particular car.

Mileage is the odometer reading at the initial test. Each band is compared with all vehicles first used in the same year with a reading in the same band, weighted by this model's own tests in each year. Bands need at least 1,000 tests. Not shown, with fewer than 1,000 tests: 60,000–89,999, 90,000–119,999 and 120,000 or more. 1 test (under 0.1%) had no usable odometer reading and is left out. How we count

Common iX3 problems at the MOT

Share of the 1,358 failed tests with a fault in each area, all years together. A test can count in more than one area, so these add up to more than 100%.

Windscreen, wipers, mirrors19.9%

MOT records show roadworthiness faults, not engine or gearbox problems. Each year page compares that year's failure areas with all vehicles first used in the same year.

Most common MOT failures on the BMW iX3

The defects recorded most often at the 1,358 failed initial tests on BMW iX3 cars, all years together, in the DVSA's own words. Each share is of failed tests, and a failed test can have more than one defect.

These are failures recorded at initial MOT tests in 2025. Retests are not counted. "All vehicles, same age" is the same defect's share of failed tests for all vehicles first used in the same years, weighted by the iX3's failed tests in each year. How we count

What to check when viewing a iX3

Based on the areas where BMW iX3 MOT tests fail most often. These are general checks anyone can do, not a mechanical inspection.

Tyres
In 67.1% of failed iX3 tests
- Check the tread on every tyre. The legal minimum for cars is 1.6 mm across the central three-quarters of the tread.
- Look for cuts, bulges, and wear on only the inner or outer edge, which can point to an alignment problem.
- Check that the spare wheel or the tyre repair kit is there.
Windscreen, wipers, mirrors
In 19.9% of failed iX3 tests
- Look for chips and cracks in the windscreen, especially in front of the driver.
- Run the wipers and washers. The blades should clear the screen without smearing.
- Check both door mirrors and the rear-view mirror are intact and adjust.

Then read the car's own MOT history. Advisories in the same area at several tests are worth asking about.

How do I check a specific iX3's MOT history?

Enter its registration in our free check. It lists that car's own MOT results, the faults and advisories recorded and the mileage at each test, and flags repeated advisories and mileage that goes down.

What MOT data can't tell you about any BMW iX3

Outstanding finance, write-offs, theft and plate changes aren't in MOT records. For a particular car, you need a history check.
