Pontiac door lock problems

Owners have filed 371 complaints with NHTSA about the doors, latches and locks on Pontiac vehicles — 1% of everything reported about the brand, across 20 models. The model that accounts for most of them is the Pontiac Montana, worst in 2005.

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.
