Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2004 S600 is engine and engine cooling with 1 filings, followed by service brakes, hydraulic:foundation components:hoses, lines/piping, and fittings (1) and interior lighting (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 2004 S600. 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.
