2016 Porsche macan — MOT failures & pass rate
22,556 MOT tests on the 2016 Porsche macan are in this dataset, and 92.5% of them passed. That is 6.2 percentage points better than mid-size SUVs of a similar age, which fail at 13.8%. Failures cluster in tyres, lighting & signalling and body, structure & corrosion.
What the MOT record shows
No single area dominates — tyres (3.5%) and lighting & signalling (2.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and joints — headlamp aim alone was recorded 369 times.
Mileage matters less than usual here: the 2016 macan fails 4.3% of the time in the 0-30k band and 6.5% at 150k+, a spread of only 2.2 points.
Fuel type barely separates them — petrol fails 6.7% of the time against 8.2% for diesel.
Advisories point at the next bill rather than this one: tyres was flagged on 17.4% of tests without failing them.
The trend is worsening — 5.1% of tests failed in 2021 against 9.5% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2016 macan
On a 2016 macan, tyres is what the MOT record says goes wrong most — it appeared in 3.5% of tests. Check these areas before you commit.
- Tyres (3.5% 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.
- Lighting & signalling (2.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (1.3% 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+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
