BMW iX MOT record in brief
Initial MOT tests in 2025, retests excluded.
72.3%
UK average, all cars
+13.6
percentage points above average
Ranked on pass rate the iX sits 110th of 575 models in the data. BMW as a brand averaged 79.3%, so this model runs 6.6 points ahead of its own brand.
A pass rate is not a reliability score. The full BMW iX MOT record has the pass rate by age, every common failure and how the iX compares with similar cars.
iX fuel types
Most BMW iX cars tested in 2025 were electric. Electric cars need an MOT from three years old like any other car, and their tyres, brakes, suspension and lights are tested the same way.
Where the iX fails its MOT
Where BMW iX cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were condition has a cut in excess of the requirements deep enough to reach the ply or cords (24.8%), condition has ply or cords exposed (16.5%) and tread depth below requirements of 1.6mm (15.8%). See every common iX MOT failure.
These are DVSA failure records across every BMW iX that failed, not a claim that every iX has these problems.
What should you check when buying a used iX?
The areas above, most common first, and what an MOT tester looks at in each.
1
Tyres
Check tread depth across the full width of every tyre (the legal minimum is 1.6mm), and look for cuts, bulges and uneven wear. 61.8% of iX failure items.
2
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 15.9% of iX failure items.
3
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 6.6% of iX failure items.
4
Steering
Feel for play, knocking or stiffness in the steering, and check there is no steering warning light. 6.6% of iX failure items.
5
Identification of the vehicle
Match the number plates and VIN to the V5C logbook, and check the plates are legal. 4.7% of iX failure items.

What the MOT record doesn't tell you
Knowing BMW iX failures cluster around tyres and visibility tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used BMW iX FAQs
Is the BMW iX reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is an 85.9% first-time pass rate for the BMW iX across 5,728 tests in 2025, above the 72.3% average for all cars.
What should I check before buying a used BMW iX?
On the car itself, start with the areas it most often fails on: tyres, visibility and lamps, reflectors and electrical equipment. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check a BMW iX's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025 (class 4 initial tests, retests excluded), licensed under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability.
