GMC electrical problems

Owners have filed 6,634 complaints with NHTSA about the electrical system on GMC vehicles — 10% of everything reported about the brand, across 96 models. The model that accounts for most of them is the GMC Sierra 1500, worst in 2014.

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.
