About the Lexus GS

The Lexus GS was MOT tested 5,873 times in 2024 (DVSA data, retests included) across 12 model years (2006 to 2018), with an average pass rate of 90%. That's comfortably above the average of 82% across all models in our data. Our records list hybrid and petrol and other fuel versions.

Best and Worst Years

Of the years with at least 100 tests, the 2017 model has the highest pass rate at 96% from 629 tests. The 2007 model has the lowest at 82%. The 14 point gap means pass rates vary somewhat between years, but no year is dramatically different. Newer cars usually pass more often simply because they are younger.

Reliability Trend

Newer Lexus GSs pass their MOT more often than older ones, by 7 percentage points on average, which is mostly down to age and wear.

Mileage Across Years

The oldest model in our data (2006) averages 119,533 miles, while the newest (2018) averages 52,828 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.
