Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1984 Chevrolet K10 Suburban dominate in one area — the engine & engine cooling, 3 of 5 reports (60%), well ahead of the next concern. None of this vehicle's 1 recall campaigns target the engine & engine cooling, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 3 a fire — a small share of the total, but worth weighing against the engine & engine cooling 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.
