Harley-Davidson engine problems

Owners have filed 669 complaints with NHTSA about the engine on Harley-Davidson vehicles — 16% of everything reported about the brand, across 136 models. The model that accounts for most of them is the Harley-Davidson Flhtcu, worst in 2007.

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.
