Expert verdict
Tyres: 1.5× the national share
Tyres make up 29.3% of everything recorded on the 2016 SEAT Mii, against 19.8% nationally — 9.5 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- When it fails, it costs. Only 30% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

What fails a 2016 Mii
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2016 Mii
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the suspension joints 1.8% of tests
“pins and bushes pin or bush excessively worn”
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.
-
Check the lights 1.8% of tests
“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.
-
Check the exhaust and emissions 1.6% of tests
“catalyst emissions Lambda reading after 2nd fast idle outside specified limits”
Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2016 Mii through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £44–£142 — and 30% of those repairs are parts that cost under £30.

|---|---|---|---|
| Has a tear, caused by separation or partial failure of its structure Tyres | Advisory | 14.5% | £45–95 |
