The 1984CHEVROLETSUBURBAN carries 6 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 1 crash, 0 fires, 5 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 1984 SUBURBAN is service brakes, hydraulic:antilock/traction control/electronic limited slip with 2 filings, followed by structure:body:door (1) and tires:tread/belt (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 57 investigation files overlapping the 1984 SUBURBAN, and 2 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page, a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.
