Where the X4 fails its MOT
Where BMW X4 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 wipers does not clear the windscreen effectively (10.4%), tread depth below requirements of 1.6mm (9.8%) and coil spring fractured or broken (9.4%). See every common X4 MOT failure.
These are DVSA failure records across every BMW X4 that failed, not a claim that every X4 has these problems.
What should you check when buying a used X4?
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. 30.7% of X4 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. 15.6% of X4 failure items.
3
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 15.5% of X4 failure items.
4
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. 14.8% of X4 failure items.
5
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 9.6% of X4 failure items.
None of this replaces the car's own record. Run a free MOT history check on the registration to see every test, advisory and recorded mileage for that car.
What the MOT record doesn't tell you
Knowing BMW X4 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 X4 FAQs
Is the BMW X4 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 84.6% first-time pass rate for the BMW X4 across 17,930 tests in 2025, above the 72.3% average for all cars.
Do older BMW X4 cars fail their MOT more often?
BMW X4 cars aged 3 to 5 years passed 88.8% of MOT tests in 2025; for examples aged 11 years and over that fell to 82.4%. On an older example, the car's own MOT history tells you more than the model average.
What should I check before buying a used BMW X4?
On the car itself, start with the areas it most often fails on: tyres, visibility and suspension. 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 X4'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.
