Porsche engine problems

Owners have filed 617 complaints with NHTSA about the engine on Porsche vehicles — 100% of everything reported about the brand, across 42 models. The model that accounts for most of them is the Porsche Cayenne, worst in 2011.

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.
