2022 Porsche Boxster — MOT failures & pass rate
The 2022 Porsche Boxster passed 97.5% of its 286 recorded MOT tests. Against coupes & convertibles of a similar age (7.9% fail rate), the 2022 Boxster comes out 5.5pp better. Failures cluster in tyres, lighting & signalling and emissions & environmental.
What the MOT record shows
No single area dominates — tyres (2.1%) and lighting & signalling (0.7%) 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 registration plates — tread depth alone was recorded 3 times.
Advisories point at the next bill rather than this one: tyres was flagged on 11.2% of tests without failing them.

What to check before buying a 2022 Boxster
On a 2022 Boxster, tyres is what the MOT record says goes wrong most — it appeared in 2.1% of tests. Check these areas before you commit.
- Tyres (2.1% 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.
- Lighting & signalling (0.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (0.4% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
