Porsche Taycan 4S 93Kwh MOT pass rate & common failures
The Porsche Taycan 4S 93Kwh appears in 7,091 MOT tests spanning model years 2020–2023, and 92.1% of them passed. That is 1.1 percentage points better than all cars of a similar age, which fail at 9.0%. Its most common failure areas are tyres, lighting & signalling and other defects.
What the MOT record shows
Tyres dominates the failure mix at 6.8% of all tests — 6.1 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 95 times.
Condition tracks the odometer closely. Failures run at 6.9% in the 0-30k band and 12.8% in the 60-90k band, a 5.8-point spread.
Advisories point at the next bill rather than this one: tyres was flagged on 20.1% of tests without failing them.
The trend is improving — the fail rate fell from 9.4% in 2023 to 7.7% in 2025, as the worst-kept examples leave the fleet.
