Porsche Taycan 4S Cross Turismo MOT pass rate & common failures
Across 3 model years and 1,802 tests, the Porsche Taycan 4S Cross Turismo passes its MOT 91.9% of the time. That is effectively the same as all cars of a similar age (8.4% 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 6.6% of all tests — 5.4 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are registration plates, headlamp aim and tread depth — registration plates alone was recorded 24 times.
Advisories point at the next bill rather than this one: tyres was flagged on 19.8% of tests without failing them.

What to check before buying a Porsche Taycan 4S Cross Turismo

- Lighting & signalling (1.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
