Used Chevrolet Impala Parts

The generation and platform decide whether a used part interchanges. Match yours before you request a quote.

• 2006–2013 (Ninth generation (GM W platform, GMX211)) — Front-drive W-body. EPA lists 2006 as a 3.5L or 3.9L V6 or a 5.3L V8, all on a 4-speed automatic. The V8 SS was dropped after 2009, and for 2012 the 3.5 and 3.9 gave way to the 3.6L LFX V6 with a six-speed — EPA lists 2012 and 2013 as 3.6L only.
• 2014–2016 (Ninth generation continued as Impala Limited (fleet only)) — The same W-body car, renamed and sold only to rental, corporate, government and police fleets, with a "Limited" trunk badge. EPA lists it as a 3.6L V6 with a 6-speed automatic. Production ended May 2016.
• 2014–2020 (Tenth generation (GM Epsilon II long-wheelbase)) — All-new and larger, sharing its platform with the Cadillac XTS and Buick LaCrosse. EPA lists 2014 as a 2.5L four, a 2.4L four with eAssist, or a 3.6L V6. Last year 2020, V6 only.

A four-cylinder settles it instantly. For 2014, EPA lists the retail Impala with a 2.5L four, a 2.4L four with eAssist, or a 3.6L V6, while the Impala Limited is listed only as a 3.6L V6. So any 2014–2016 Impala with a four-cylinder is the tenth-generation car. If it is a V6, check the trunk lid: the fleet car carries a "Limited" badge.

The confusing part is that the two cars do share an engine. From 2012 the ninth generation used the 3.6L LFX V6, and the tenth generation uses the same 3.6L LFX with a 6T70 six-speed behind it. That overlap is real and worth searching. Nothing else overlaps: different platforms, bodies, glass, lamps, interiors and wiring. Order the engine and transmission by engine code, and order body, lighting, glass, interior and electronics by which car you actually have.

A second boundary hides inside the ninth generation itself. Cars up to 2011 are 3.5L or 3.9L V6 cars on a four-speed automatic (with the 5.3L V8 in the 2006–2009 SS); from 2012 they are 3.6L cars on a six-speed. A 2011 engine or transmission does not answer a 2012 car even though the body looks identical.

• NHTSA campaign 14V092000 covers 2014 Impala, Malibu, Cruze and Traverse plus several Buick and GMC models with automatic transmissions: the shift cable adjuster can disengage from the transmission shift lever, so the indicated gear may not be the gear the car is in and it can roll away after being shifted to Park. Check open campaigns by VIN and leave shift-linkage work to a mechanic.
• NHTSA campaign 15V085000 covers 2014 Impalas whose electronic parking brake piston actuation arm may not fully retract, leaving the pads partially engaged and generating enough heat to cause a fire — a failure to comply with FMVSS 135. Brakes are not a guess-and-fit purchase: have a dragging brake diagnosed and fitted by a professional.
• Many ninth-generation and Limited cars are ex-fleet or ex-police, which matters for parts. NHTSA campaign 12V377000 recalled 2008–2012 Impala police vehicles for front lower control arms that may fracture, and the notice states it does not include non-police Impalas. The police 9C1 and 9C3 packages also carried heavy-duty front suspension, a high-output 150-amp alternator and heavy-duty cooling, so a part pulled from "a 2011 Impala" may be police-spec.

Safety- and emissions-related parts should be diagnosed and installed by a licensed mechanic.

Send the full VIN, the model year, the engine and — for 2014, 2015 and 2016 cars — whether the trunk lid reads "Impala" or "Impala Limited," because that word decides which of two unrelated cars we search. Typical requests are engines, transmissions, alternators, starters, radiators, suspension parts, headlamps and collision panels. We quote against your VIN rather than publish stock or prices.
