New Car Assessment Program
The 1991DODGEMONACO carries 55 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 3 crashes, 0 fires, 1 injury, 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 1991 MONACO is visibility:defroster/defogger/hvac system:heater core with 9 filings, followed by service brakes, hydraulic:foundation components:disc:rotor (5) and seat belts (4). 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 20 investigation files overlapping the 1991 MONACO, and 1 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.
