Pontiac suspension problems

Owners have filed 1,428 complaints with NHTSA about the suspension on Pontiac vehicles — 4% of everything reported about the brand, across 23 models. The model that accounts for most of them is the Pontiac GTO, worst in 2006.

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.
