Used buying checklist

Lexus Gs reliability, common problems and used buying checks

A used Lexus Gs looks better than average for reliability in UK MOT data: 7.6% of 3,797 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for corrosion and structure, windscreen, wipers, and mirrors, and lights and electrical.

Is a used Lexus Gs a good buy?

It can be, if the exact car has a clean history for corrosion and structure, windscreen, wipers, and mirrors, and lights and electrical.

What should I check first?

Start with corrosion and structure, windscreen, wipers, and mirrors, and lights and electrical, then compare the car's mileage and recall record below.

Sources used: DVSA MOT tests (Apr 2026); vehicle recalls (Apr 2026); MOT fault wording (May 2025). MOT data does not capture every reliability issue, especially intermittent engine, gearbox or infotainment faults that do not appear during the test.

Better than average in our MOT data
Green light if The car has a tidy MOT pattern, recent repairs for corrosion and structure, windscreen, wipers, and mirrors, and lights and electrical, matching tyres, and paperwork for service or recall work.
Renegotiate if The latest MOT mentions corrosion and structure, windscreen, wipers, and mirrors, and lights and electrical, consumables are due together, or the seller cannot show what was fixed after advisories.
Walk away if Dangerous defects, corrosion near structural areas, warning lights, or the same component family keep returning without clear repair evidence.
  • Repeat unresolved MOT notes for corrosion and structure, windscreen, wipers, and mirrors, and lights and electrical
  • corrosion and structure appearing across more than one MOT
  • Any dangerous MOT failure on the exact car, especially if the same area appears again later
  • A seller who cannot explain MOT wording such as "excessively corroded"
