BMW X4 common problems and MOT failures
What goes wrong on a used BMW X4, year by year: known faults from UK buying guides, the parts flagged at MOT more than on other cars (from 51,546 MOTs done during 2023–2025), and what to check before you buy one.
The 2025 BMW X4
Cars registered in 2025 haven’t had their first MOT yet (it’s due at 3 years old), so there are no MOT results to show. There are no known faults on record for this year in the UK buying guides we use, so the rest of this page covers the BMW X4 as a whole.
What to check on a 2025 car
- Warranty left
Ask for the date it was first registered and check how much of the maker’s warranty is left, and that it transfers to you. Electric and hybrid batteries usually have a longer, separate warranty.
- Servicing
Servicing on time with the maker’s schedule keeps the warranty valid. Ask for the service book or the dealer’s digital record.
- Finance
Nearly new cars are often still on finance. A history check shows outstanding finance, and whether it has been written off or stolen.
- Recalls
Ask whether any recall work has been done, and check the reg on GOV.UK’s free recall checker.
- Logbook (V5C)
The name and address should match the seller, and the VIN on the V5C should match the car.
Other years
Most years have their own guide. The year is when the car was first registered (it’s on the logbook, or check the reg below).
What usually goes wrong with a BMW X4?
We haven’t found widely reported faults for the BMW X4 in the UK buying guides we use yet. That doesn’t mean it has none, so check the car carefully and look at the MOT weak spots below.
Common BMW X4 MOT failures to check
Parts flagged at MOT well above the usual rate for cars the same age, in more than one year. From the DVSA’s results for every MOT done in Great Britain during 2023–2025.
Steering rack inner joints
up to 13× usualStands out on cars registered in 2014, 2015 and 2016.
Rough price £100–£450 our estimateAt the viewing: On a straight road the steering wheel should sit straight. Listen for knocks when turning, and check the steering feels even.
Coil springs
up to 2.1× usualStands out on cars registered in 2015, 2016 and 2017.
Rough price £175–£400 (pair, one axle) ClickMechanicAt the viewing: Look behind each wheel for a snapped spring coil, and listen for a clunk or twang when turning the wheel lock to lock with the car stopped.
BMW X4 MOT pass rate by year
Of the years since 2005 with plenty of MOT tests, the 2014 BMW X4 did best (81% passed first time, 11 points above all 2014 cars) and the 2020 did worst (88%, 1 point above all 2020 cars). Older cars fail more, so compare each year with all cars registered the same year.
Questions to ask the seller before buying a BMW X4
Ask before you travel to see it. A seller who knows the car will have answers, and receipts.
- Any recent work on the steering rack inner joints? (Flagged at MOT 13× as often on the BMW X4 as on other cars the same age.)
- Any recent work on the coil springs? (Flagged at MOT 2.1× as often on the BMW X4 as on other cars the same age.)
- Can I see the service history and receipts for any big jobs?

Where this comes from: MOT figures are the DVSA’s anonymised results for every MOT test done in Great Britain during 2023–2025, grouped by the year each car was first registered. How many are on the road is from the Department for Transport’s vehicle licensing statistics. Known faults are from UK buying guides, in our own words, with links. How we score
