1978 Chevrolet Impala

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1978 Impala.

The 1978 Chevrolet Impala is presented here as part of the model line whose owner‑complaint record is documented from 1991 through 2020. During that span the highest number of complaints occurred in 2004, with 1,071 reports, while the lowest point came in 1997, with just a single complaint. Because the 1978 model year falls outside the 1991‑2020 window, the complaint statistics do not directly locate it within that reliability trend. Consequently, any assessment of its dependability must rely on sources beyond the supplied complaint data.
