Pre-MOT Inspection Checklist for Kia Stonic Maxx Owners

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

• 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.

The twenty areas with the most Kia Stonic Maxx cars in the record, sorted by car count — sort the columns for a different question. 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 →
