Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 1998 Chevrolet S10 2WD dominate in one area — the visibility, 199 of 660 reports (30%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 64 of the reports describe a crash and 9 a fire — a small share of the total, but worth weighing against the visibility 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.
