Lexus RX common problems and MOT failures
What goes wrong on a used Lexus RX, year by year: known faults from UK buying guides, the parts flagged at MOT more than on other cars (from 64,013 MOTs done during 2023–2025), and what to check before you buy one.
The 2026 Lexus RX
Cars registered in 2026 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 Lexus RX as a whole.
What to check on a 2026 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).

Questions to ask the seller before buying a Lexus RX
Ask before you travel to see it. A seller who knows the car will have answers, and receipts.
- Any recent work on the suspension arm bushes and joints? (Flagged at MOT 2.6× as often on the Lexus RX as on other cars the same age.)
- Any recent work on the sub-frame? (Flagged at MOT 2.5× as often on the Lexus RX as on other cars the same age.)
- Any recent work on the corroded fuel pipes? (Flagged at MOT 6× as often on the Lexus RX 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
