2013 Mitsubishi Asx — MOT failures & pass rate
15,081 MOT tests on the 2013 Mitsubishi Asx are in this dataset, and 80.2% of them passed. Small SUVs of a similar age fail at 20.6%, so the 2013 Asx sits squarely on the average. Failures cluster in brakes, suspension and lighting & signalling.
What the MOT record shows
No single area dominates — brakes (9.2%) and suspension (8.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), brake pads and track rod end — rbt (sp) alone was recorded 544 times.
A 150k+ example is materially riskier than a 0-30k one: 25.9% versus 6.7%.
Split by fuel, diesel examples fail 2.0pp more often than petrol ones (20.7% vs 18.8%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: brakes was flagged on 32.4% of tests without failing them.
The trend is worsening — 16.0% of tests failed in 2021 against 23.7% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2013 Asx
On a 2013 Asx, brakes is what the MOT record says goes wrong most — it appeared in 9.2% of tests. Check these areas before you commit.
- Brakes (9.2% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Suspension (8.3% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Lighting & signalling (5.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
