Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 W-Series Commercial.
The 2006 GMC Truck W-Series Commercial represents a commercial-truck offering within a generation surveyed from 2001 to 2010. Complaint records for that entire span identify 2002 as the reference year, registering exactly one complaint—a volume that stands as both the highest and lowest annual count on file. That solitary data point positions the 2006 model year within a remarkably quiet stretch of the W-Series reliability history, leaving researchers with minimal documented owner complaints to analyze.
