# Subaru WRX 2015–2021 · 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.

[← Full case file](https://carcasefile.com/vehicles/subaru-wrx-2015-2021/)

Check 01

Demand the tune/mod history. A flash tune, downpipe, or big turbo on the FA20DIT or EJ257 dramatically raises bearing/ringland risk. No documentation = assume the worst and price accordingly (or walk).

Check 02

Pull a recent oil sample / ask about oil consumption. The FA20DIT is known to drink oil; check the dipstick and ask how often they top off. Metallic glitter or a low level on a 'topped before sale' car is a red flag for bearing wear.

Check 03

Cold-start and listen for bottom-end knock or a metallic rattle that quiets as it warms. That is the early bearing-failure tell. Have it inspected by a Subaru-literate shop before buying.

Check 04

On the WRX manual, test the clutch hard: feel for judder/shudder when easing off from a stop, listen for a throwout-bearing whine that changes with the pedal. A clutch job here is transmission-out labor.

Check 05

On the CVT (WRX automatic), drive it from cold at low speed and light throttle and feel for shudder or hesitation. That is the early TR690 torque-converter complaint.

Check 06

Ask when (or if) the intake valves were ever walnut-blasted. Most VA WRXs past ~60k–80k miles are carrying significant carbon; a never-cleaned high-mileage car will feel down on power.

Check 07

Check for an alignment/odd tire wear and listen for wheel-bearing growl at speed, a common chassis wear item.

Check 08

Verify the EJ257 (STI) short-block warranty-extension status by VIN at a Subaru dealer if the car is within the window.
