Mini fuel system problems

Owners have filed 159 complaints with NHTSA about the fuel system on Mini vehicles — 2% of everything reported about the brand, across 15 models. The model that accounts for most of them is the Mini Cooper, worst in 2015.

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.
