The 1991MERCURYMARQUIS carries 10 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 2 crashes, 3 fires, 4 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 1991 MARQUIS is electrical system:alternator/generator/regulator with 2 filings, followed by service brakes, hydraulic:foundation components (1) and steering: steering wheel/handle bar (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 22 investigation files overlapping the 1991 MARQUIS. 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.
