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 1989 Chevrolet Blazer 2WD top in one area — the seat belts, 7 of 42 reports (17%), well ahead of the next concern. None of this vehicle's 4 recall campaigns target the seat belts, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 9 of the reports describe a crash and 7 a fire — a small share of the total, but worth weighing against the seat belts 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.
