GMC acceleration problems

Owners have filed 1,315 complaints with NHTSA about the throttle and cruise control on GMC vehicles — 2% of everything reported about the brand, across 59 models. The model that accounts for most of them is the GMC Sierra, worst in 1999.

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.
