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 1985 Chevrolet Suburban 2WD top in one area — the tires, 2 of 12 reports (17%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 1 of the reports describe a crash and 1 a fire — a small share of the total, but worth weighing against the tires 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.
