Porsche electrical problems

Owners have filed 386 complaints with NHTSA about the electrical system on Porsche vehicles — 14% of everything reported about the brand, across 28 models. The model that accounts for most of them is the Porsche Taycan, worst in 2020.

These are raw counts. A model that sold in millions appears near the top for that reason alone — the grade never compares one model with another.
