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 1999 SC400 is service brakes, hydraulic:pedals and linkages with 1 filings, followed by vehicle speed control:accelerator pedal (1) and exterior lighting:headlights:concealment devices (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.
