A pass rate is not a reliability score. The full BMW iX3 MOT record has the pass rate by age, every common failure and how the iX3 compares with similar cars.
iX3 fuel types
Most BMW iX3 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 iX3 fails its MOT
Where BMW iX3 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 (33.6%), condition has ply or cords exposed (18.3%) and wipers does not clear the windscreen effectively (10.3%). See every common iX3 MOT failure.
These are DVSA failure records across every BMW iX3 that failed, not a claim that every iX3 has these problems.
What should you check when buying a used iX3?
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. 65.3% of iX3 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. 15.7% of iX3 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. 11.4% of iX3 failure items.
4
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 2.3% of iX3 failure items.
5
Identification of the vehicle
Match the number plates and VIN to the V5C logbook, and check the plates are legal. 2% of iX3 failure items.

What the MOT record doesn't tell you
Knowing BMW iX3 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 iX3 FAQs
Is the BMW iX3 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 85.4% first-time pass rate for the BMW iX3 across 9,598 tests in 2025, above the 72.3% average for all cars.
What should I check before buying a used BMW iX3?
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 iX3'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.
