Expert verdict
Brakes: 1.7× the national share
Brakes make up 36.2% of everything recorded on the 2018 Mitsubishi Asx, against 20.9% nationally — 15.3 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- When it fails, it costs. Only 31% 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 2018 Asx
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 2018 Asx
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 brakes 1.7% of tests
“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.
-
Check the suspension joints 1.4% of tests
“track rod end ball joint dust cover damaged or 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.
-
Check the wipers and washers 1.2% of tests
“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.
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 2018 Asx through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £27–£65 — and 31% of those repairs are parts that cost under £30.
