Pre-MOT Inspection Checklist for Kia Stonic Owners

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

  • the wipers and washers — “wipers does not clear the windscreen effectively”

    Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.

  • the brakes — “brake pads less than 1.5 mm thick”

    Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.

  • 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.
