2002 Chevrolet Impala

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2002 Impala.

Body PASSENGER CAR

The 2002 Chevrolet Impala is a full‑size passenger car built on Chevrolet’s long‑running rear‑wheel‑drive platform, equipped with an engine that requires a 5‑quart fill of 5W‑30 API oil. Across its production span from 1991 to 2020, the model line accumulated 809 owner complaints for this year, with the electrical system emerging as the most frequent trouble area and seven recalls recorded. Compared with the extremes of the series—only one complaint in 1997 and a peak of 1,071 in 2004—the 2002 model sits in the middle of the reliability curve, indicating a generally average but still noteworthy record for researchers assessing its durability.

From the factory this vehicle uses a BCI 78 · 600 CCA battery, OE oil filter 12731175. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The eighth-generation Impala (2000–2005) opened with a sharp surge in complaints and recalls: 856 complaints and 10 recalls in 2000, followed by 750 complaints and 10 recalls in 2001. The 2002 model year sits squarely within this troubled arc, recording 809 complaints and 7 recalls, while investigations held at 2—a pattern that persisted until 2003 before declining. Notably, 2002’s top complaint areas were electrical system (199), exterior lighting (87), and engine & engine cooling (76), with 40 crash and 32 fire complaints, indicating significant safety-related concerns. Although recalls dipped slightly from the initial peak, the complaint volume remained high, and the generation did not show meaningful improvement until 2005. Given these figures, the 2002 Impala falls in a period of elevated risk, making it a poor choice for a used purchase.
