17 NHTSA complaints for this specific cohort.
NHTSA overall rating
Not crash-tested
New Car Assessment Program
The 1991MERCEDES-BENZ300 SERIES carries 17 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 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 300 SERIES is engine and engine cooling:cooling system:radiator assembly with 1 filings, followed by power train:automatic transmission:lever and linkage:column shift (1) and vehicle speed control:accelerator pedal (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 15 investigation files overlapping the 1991 300 SERIES. 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.
