Reliability & federal safety record

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

The 1973 model year registers a single Service Brakes, Hydraulic complaint and one crash complaint, with zero fire-related incidents, representing significantly lower federal activity than any year in the provided 1990–2026 record, which bottoms out at five complaints in 2008. This target year falls entirely outside the documented escalation arc, which climbs from 43 complaints in 1990 to a peak of 1,418 in 1995 alongside 11 recalls and 8 investigations before declining through the 2000s. Unlike the high-volume years that dominate the federal record, the 1973 model shows minimal safety reporting and predates the systemic issues characterizing the later generation documented in the dataset. The data does not specify root causes for the sole 1973 complaint, nor does it place this model year within the recall-heavy trends visible from 1990 onward. For prospective buyers, this statistical isolation from the documented complaint surge—coupled with its negligible federal footprint—makes the 1973 Blazer a comparatively safe acquisition, contingent on thorough inspection for age-related wear.
