Pre-MOT Inspection Checklist for Lexus RX400 H Owners

These checks follow this Lexus RX400 H's own most-recorded failure strings, starting with what a tester is most likely to flag on a Lexus RX400 H.

• the suspension joints — “ball joint dust cover severely deteriorated”

  With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.

• the lights — “position lamp not working”

  Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

• the shock absorbers — “shock absorbers has a serious fluid leak”

  Press down hard on each corner of the car and let go. It should settle in one bounce; if it keeps rocking, or you can see oil weeping down a shock absorber, that is the fault a tester will find.

Derived from the DVSA failure strings testers recorded for the Lexus RX400 H. A check that finds nothing means the item is likely fine, not that the test is guaranteed.

Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →
