2012 Chevrolet Impala

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2012 Impala.

Body PASSENGER CARTransmission Automatic 6-spd

The 2012 Chevrolet Impala is a full-size passenger car equipped with a 6-speed automatic transmission and powered by an engine requiring 6 quarts of 5W-30 motor oil, achieving EPA fuel economy ratings of 18 mpg city, 29 mpg highway, and 22 mpg combined. This model year recorded 258 owner complaints, with the electrical system emerging as the primary concern among the three recalls issued for the vehicle. Against the broader complaint history spanning from 1991 to 2020, where complaints ranged from a low of just 1 in 1997 to a peak of 1,071 in 2004, the 2012 Impala falls well below the problematic 2004 peak, suggesting a notable improvement in overall reliability compared to that troubled year—though the electrical system issues remain a documented weakness worth noting for researchers tracking the model's longitudinal performance.

Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 34 · 600 CCA battery, OE oil filter 12690386. Note the factory engine air filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 engine oil and filter every 7,500 mi; spark plugs every 97,500 mi; coolant every 7,500 mi. The big-interval services (every 7,500 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 2012 Chevrolet Impala sits at a relative low point in the model's federal complaint history, with 258 complaints and 3 recalls, down sharply from 505 complaints in 2011 and well below the 630 complaints and 12 recalls that followed in 2014. Across this generation, complaints and recalls trended downward from the 2008-2009 peak before the 2012-2013 lull, then spiked dramatically in 2014. Technical Service Bulletins actually continued climbing through 2012 to 1,472, reflecting ongoing service guidance rather than a spike in safety defects. The leading 2012 complaint categories were Electrical System (23), Steering (21), Unknown or Other (17), and Electronic Stability Control (13), with 20 crash-related and 5 fire-related complaints, though the data does not specify root causes. Given the low complaint volume, minimal recalls, and absence of investigations, 2012 looks like one of the more favorable years in this generation to buy used.
