New Car Assessment Program

The 1984FORDBRONCO II carries 14 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 1 crash, 7 fires, 2 injuries, and 1 fatality. 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 BRONCO II is electrical system:ignition:switch with 4 filings, followed by engine and engine cooling:engine:gasoline (3) and fuel system, gasoline:storage:tank assembly (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 177 investigation files overlapping the 1984 BRONCO II, and 8 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.
