The MERCEDES-BENZ300SD appears in NHTSA's Office of Defects Investigation database with 14 consumer safety complaints and 0 recall campaigns across 3 model years (1984–1993). That averages roughly 5 complaints per model year. Report counts can differ between model years for many reasons; this dataset does not establish the cause of a difference.
Complaint volume on a nameplate alone is not a reliability verdict: a long-running bestseller can accumulate more filings than a low-volume niche model because more vehicles are on the road. The table below shows report counts and published NHTSA crash-test ratings side by side for each model year. The filing-year histogram shows the timing of submitted reports, not a causal trend.
NHTSA has 15 investigation files tied to this model. Investigation records, complaint reports, and recall campaigns each provide different context. Use the official NHTSA VIN lookup and the underlying notices to research a specific vehicle; PlainCars does not infer a vehicle-risk or pricing conclusion from these records.
