Hummer brake problems

Owners have filed 90 complaints with NHTSA about the braking system on Hummer vehicles — 100% of everything reported about the brand, across 4 models. The model that accounts for most of them is the Hummer H2, worst in 2003.

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.
