Buick fuel system problems

Owners have filed 1,517 complaints with NHTSA about the fuel system on Buick vehicles — 5% of everything reported about the brand, across 24 models. The model that accounts for most of them is the Buick Lesabre, worst in 1998.

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.
