2014 Porsche macan — MOT failures & pass rate
The 2014 Porsche macan passed 89.6% of its 6,552 recorded MOT tests. Mid-size SUVs of a similar age fail 18.0% of the time, so this is 7.6pp better than the group it competes with. Failures cluster in tyres, body, structure & corrosion and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.7%) and body, structure & corrosion (3.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are joints, headlamp aim and tread depth — joints alone was recorded 248 times.
Mileage is the strongest signal on the record: 5.1% of 0-30k cars fail, rising to 17.5% once past 150k — 3.4× the risk.
Split by fuel, diesel examples fail 4.4pp more often than petrol ones (11.7% vs 7.2%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 18.6% of tests without failing them.
The trend is worsening — 8.6% of tests failed in 2021 against 11.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2014 macan
On a 2014 macan, tyres is what the MOT record says goes wrong most — it appeared in 3.7% of tests. Check these areas before you commit.
- Tyres (3.7% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Body, structure & corrosion (3.3% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Lighting & signalling (3.3% 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.
