BMW X6 common problems and MOT failures

What goes wrong on a used BMW X6, year by year: known faults from UK buying guides, the parts flagged at MOT more than on other cars (from 46,482 MOTs done during 2023–2025), and what to check before you buy one.

The 2023 BMW X6

Cars registered in 2023 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 X6 as a whole.

What to check on a 2023 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.

Questions to ask the seller before buying a BMW X6

Ask before you travel to see it. A seller who knows the car will have answers, and receipts.

  1. Any recent work on the ball joint? (Flagged at MOT 2.9× as often on the BMW X6 as on other cars the same age.)
  2. Any recent work on the engine oil leaks? (Flagged at MOT 2× as often on the BMW X6 as on other cars the same age.)
  3. Any recent work on the side repeaters? (Flagged at MOT 4.8× as often on the BMW X6 as on other cars the same age.)
  4. 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
