GMC fuel system problems

Owners have filed 3,443 complaints with NHTSA about the fuel system on GMC vehicles — 5% of everything reported about the brand, across 94 models. The model that accounts for most of them is the GMC Envoy, 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.
