Buick door lock problems

Owners have filed 258 complaints with NHTSA about the doors, latches and locks on Buick vehicles — 1% of everything reported about the brand, across 17 models. The model that accounts for most of them is the Buick Lesabre, worst in 1997.

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.
