Pre-MOT Inspection Checklist for Lexus GS450H Owners

These checks follow this Lexus GS450H's own most-recorded failure strings, starting with what a tester is most likely to flag on a Lexus GS450H.

• 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 windscreen — “windscreen damaged”

  Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.

• 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 GS450H. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
