Porsche Taycan 4X2 MOT pass rate & common failures
2,818 MOT tests on the Porsche Taycan 4X2 (2021–2023) give it a 92.1% pass rate. That is effectively the same as all cars of a similar age (8.5% fail rate), so the MOT record here is unremarkable in either direction. Its most common failure areas are tyres, lighting & signalling and other defects.
What the MOT record shows
Tyres dominates the failure mix at 6.9% of all tests — 5.8 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are tread depth, registration plates and headlamp aim — tread depth alone was recorded 91 times.
Mileage matters less than usual here: the Taycan 4X2 fails 6.7% of the time in the 0-30k band and 9.3% at 60-90k, a spread of only 2.6 points.
Advisories point at the next bill rather than this one: tyres was flagged on 22.2% of tests without failing them.

What to check before buying a Porsche Taycan 4X2
- Tyres (6.9% 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 (1.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Other defects (0.6% of tests): Miscellaneous items not in the main categories. Typical repair: varies.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
