Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The provided federal record spans 1990 through 2002 and does not include a 1984 entry, so the 1984 Cadillac Eldorado cannot be placed on the same year-by-year arc as the data shown. Across the recorded 1990–2002 period, complaints trended upward from 35 in 1990 to a peak of 81 in 1996 before declining to 16 by 2002, while recalls were concentrated in the early-to-mid 1990s and investigations peaked at 4 in 1995. For the 1984 model specifically, the JSON lists only limited complaint-area totals: Engine & Engine Cooling, Structure, and Service Brakes/Hydraulic each with 2 complaints, Electrical System with 1, and zero crash or fire complaints. Because no year-by-year federal figures exist for 1984 in this dataset, it is impossible to judge whether 1984 is better or worse than adjacent model years. The low absolute complaint counts in the provided categories are superficially encouraging, but without comparable annual context, the data do not support a confident buy recommendation; a buyer should treat 1984 as an unverified outlier in this record.
