All generations and engines together · 7,952 MOT tests in the 2025 data
Computed from DVSA MOT results, all of Great Britain, 2025. Nothing here is opinion.
Share of tests where each item was recorded. The dark tick is the class average across all tracked models; bars are scaled within each group.
The rows that judge the model rather than its keeper. 7,952 tests in this band.
Tyres, pads and stone chips say more about how the car was driven and maintained than about how it was built.
Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.
Porsche recalled cars built roughly from late 2019 through early 2024 over LG-supplied battery cell modules that can develop an internal short circuit with no warning light before a thermal event. Around 27,000 cars worldwide are covered by the recall opened in October 2024, and Porsche replaces the affected cell block module free of charge. Any pre-owned Taycan in this build window should show the recall as completed on its service history.
Porsche recalled over 40,000 Taycans (and the related Audi e-tron GT) because the wiring harness under the front seats can be damaged when the seat is slid back and forth, in the worst case knocking out the airbag and seatbelt pretensioner circuits. No injuries have been linked to it and the fix is a free dealer inspection and repair where needed. It lines up neatly with the model's measured MOT weak spot, seatbelts and airbags, and gives an actual manufacturer-acknowledged reason a fault in that area could exist on a car that hasn't had the recall done.
A recurring owner complaint: the small 12V battery that runs the low-voltage electronics drains flat after anywhere from 4 to 14 days of the car sitting unused, occasionally even while plugged in at home. Owners point to a software loop that keeps control modules awake overnight; Porsche has pushed several software updates but the complaints keep resurfacing across model years. A replacement 12V battery runs roughly £150-250 fitted, though the drain itself often comes back after a new one goes in.
Because regenerative braking does most of the slowing, the friction brakes see far less use than on a combustion Porsche, and owners report the iron front discs picking up surface rust, pitting and judder within a couple of years even at modest mileage. Some owners and independent garages call this normal for a car that barely uses its friction brakes, others have had discs replaced under dealer goodwill or paid out of pocket, roughly £400-800 a pair. There's no TSB or recall, it's an ongoing argument among owners over whether it's a design issue or just how an EV's brakes age.
A repeated complaint is the central PCM touchscreen freezing solid, sticking on the Porsche startup logo, or spontaneously rebooting while driving, sometimes losing sat-nav, climate and drive-mode control for anywhere from a few seconds to over an hour. It has shown up on cars fresh from delivery through to ones with 20,000-plus miles, across different software versions. Porsche's usual fix is a software update or a PCM reset at a dealer, free under warranty, but owners report it recurring after the fix.
