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 Blazer 2WD dominate in one area — the seat belts, 3 of 9 reports (33%), well ahead of the next concern. None of this vehicle's 3 recall campaigns target the seat belts, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 5 of the reports describe a crash and 0 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.
