Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1984 Electra Park Avenue.
The 1984 Buick Electra Park Avenue stands as a specific reference point within the model's lineage, characterized mechanically by an engine requiring four quarts of oil with 20W-20, 10W-30, or 10W-40 viscosity specifications. In the context of the model's reliability history, this year occupies a quiet yet pointed position, generating only two total owner complaints while being subject to two formal recalls. Because Engine & Engine Cooling ranks as the top complaint area, this localized focus means that while overall owner grievances are minimal, the vehicle's primary historical vulnerabilities center squarely on its core mechanical and thermal systems.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1984 Buick Electra Park Avenue dominate in one area — the engine & engine cooling, 1 of 2 reports (50%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the engine & engine cooling, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 1 a fire — a small share of the total, but worth weighing against the engine & engine cooling pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
