Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1984 Corvette.
The 1984 Chevrolet Corvette introduced the fourth-generation platform with a 4-speed automatic transmission and a V8 engine requiring 4 quarts of 20W-20, 20W-40, or 20W-50 oil, achieving EPA ratings of 13 city, 20 highway, and 15 combined mpg. With 22 total owner complaints and 6 recalls—the most common issue involving seat belts—this model year sits well below the peak of 588 complaints recorded for the 2008 Corvette in the model’s 1990–2025 history, though it is not the lowest (the 1992 model had only 8). This places the 1984 as a relatively reliable early C4, with its modest complaint count suggesting that, aside from the noted seat belt concerns, it avoided the major trouble areas that would later plague the model.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The provided year-by-year federal record begins in 1990 and contains no data for 1984 or any prior year, which means the 1984 Corvette cannot be directly compared to adjacent model years or situated within the complaint and recall trend arc visible across this dataset. Isolated metrics for the target year show seat belts generating the highest complaint count at 8, with vehicle speed control, power train, and equipment each at 2, alongside 1 crash complaint and 0 fire complaints. Because the record offers no recall, investigation, or TSB figures for 1984, the data does not specify whether these complaints reflect isolated incidents or broader systemic issues. Relative to the triple-digit complaint peaks and multi-recall years recorded for much later model years in this file, the raw 1984 counts are low, though that comparison spans different generations and decades of vehicle aging. The concrete takeaway is that 1984 sits entirely outside this federal record’s timeline, so a prospective buyer has only a sparse, uncontextualized complaint snapshot to evaluate and should therefore treat this as an unverified rather than demonstrably good year to buy based solely on this data.
