Porsche macan MOT pass rate & common failures
The Porsche macan appears in 141,111 MOT tests spanning model years 2014–2025, and 93.4% of them passed. Mid-size SUVs of a similar age fail 11.8% of the time, so this is 5.3pp better than the group it competes with. Its most common failure areas are tyres, lighting & signalling and brakes.
Best and worst macan years
Ranked across macan years with at least 1,000 tests. Older cars fail more simply because they are older — compare years close together in age before drawing conclusions.
What the MOT record shows
Build year matters more than the headline suggests: 2022 cars pass 95.5% of the time while 2014 cars manage 89.6%, a 5.8-point spread.
No single area dominates — tyres (3.5%) and lighting & signalling (1.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, headlamp aim and joints — tread depth alone was recorded 2,298 times.
A 150k+ example is materially riskier than a 0-30k one: 12.3% versus 4.3%.
The petrol cars hold up better: 5.5% fail against 8.6% for diesel, a 3.0-point gap across 141,111 tests.
Tyres is the most common advisory, noted on 16.9% of tests — work that passed today but is likely due soon.

What to check before buying a Porsche macan
- 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 (1.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (0.9% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
