Buick engine problems

Owners have filed 4,108 complaints with NHTSA about the engine on Buick vehicles — 15% 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.
