2015 Porsche Panamera — MOT failures & pass rate
3,705 MOT tests on the 2015 Porsche Panamera are in this dataset, and 88.9% of them passed. Executive cars of a similar age fail 14.0% of the time, so this is 2.9pp better than the group it competes with. Failures cluster in tyres, suspension and lighting & signalling.
What the MOT record shows
Tyres dominates the failure mix at 6.1% of all tests — 3.6 points clear of suspension, so it is the first thing to check.
At component level the recurring items are tread depth, coil spring and headlamp aim — tread depth alone was recorded 114 times.
Condition tracks the odometer closely. Failures run at 5.3% in the 0-30k band and 16.9% in the 120-150k band, a 11.6-point spread — more than double.
Split by fuel, diesel examples fail 3.8pp more often than petrol ones (11.9% vs 8.1%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 22.0% of tests without failing them.
The trend is worsening — 10.4% of tests failed in 2021 against 12.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2015 Panamera
On a 2015 Panamera, tyres is what the MOT record says goes wrong most — it appeared in 6.1% of tests. Check these areas before you commit.
- Tyres (6.1% 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.
- Suspension (2.5% 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 (2.0% 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.
