Chevrolet Impala 2014–2020 · Pre-purchase checklist

Bring this to the inspection. Every check below is specific to this generation's documented failure modes — not generic used-car advice.

1. Check 01

   Strongly prefer the 3.6L V6 over the 2.5L four-cylinder — confirm which engine is in the car (V6 has noticeably more power and a cleaner reliability record).

2. Check 02

   On any 2.5L car, pull the dipstick warm and ask the seller how often they add oil; creeping consumption with no leak and no smoke is the tell.

3. Check 03

   On 2014–2015 cars, have a Chevy dealer check the VIN for the parking-brake (14471) and power-steering (14V450/recall 14330) recalls — confirm both were completed.

4. Check 04

   Test the electronic parking brake: it should set and fully release without a warning light or drag.

5. Check 05

   Drive through 2nd-to-3rd shifts repeatedly; a hard or surging shift points to transmission solenoid wear.

6. Check 06

   Cycle the climate control through hot and cold and across vents — clicking or stuck temperature actuators are a known annoyance.

7. Check 07

   Try removing the key (on keyed cars) — a key that sticks in the ignition is a commonly reported nuisance.

8. Check 08

   On higher-mileage V6 cars, check for coolant weeping at the water pump and any cold-start timing-chain rattle.
