Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2001 Chevrolet C-Series HD Truck dominate in one area — the fuel/propulsion system, 1 of 2 reports (50%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the fuel/propulsion system, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the fuel/propulsion system pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
