Subaru WRX IV (VA) (2015 – 2021)

Reliability score : 7.2/10

The fourth-generation Subaru WRX (chassis code VA) marks a historic turning point: it is the first time the model officially detaches from the "Impreza" name to become a standalone lineup. Launched in 2014 for the 2015 model year, it offers two distinct philosophies. The standard WRX adopts the new FA20F engine (2.0L direct-injection turbo) coupled with a 6-speed manual gearbox or a CVT transmission (Lineartronic). The WRX STI, the radical version, retains the iconic but aging EJ257 block (2.5L indirect-injection turbo) associated with a reinforced manual gearbox and a driver-controlled center differential (DCCD). Although the interior and soundproofing lag behind European standards, the WRX (VA) shines with its ultra-rigid chassis and Symmetrical AWD system offering imperial traction, sup

✅ Strengths

Exceptional traction thanks to the Symmetrical AWD (especially with the STI's DCCD)
Very rigid chassis and secure road handling
Very robust 6-speed manual gearbox (particularly the STI's)
Versatility of a 4-door sedan with a decent trunk
Enthusiast community and huge aftermarket parts market

⚠️ Weaknesses

High fuel consumption (especially on the 2.5L STI)
Dated interior plastic quality and infotainment system
Mediocre soundproofing (road and wind noise on the highway)
EJ257 engine (STI) fragile if poorly maintained or poorly tuned
Often expensive insurance

🎯 Verdict

Buying a used Subaru WRX or WRX STI (VA) is an exercise that requires patience and rigor. These are cars with a unique character, offering traction and sensations rare in this price range. However, mechanical reliability depends almost exclusively on the previous owner's behavior. The WRX's FA20F engine is generally more modern and reliable for daily use, while the STI's venerable EJ257 requires obsessive maintenance (oil changes every 8,000 km, strict adherence to warm-up times). Avoid heavily modified models or those without a clear history. If you find a stock example, well-maintained and driven with respect, it is a highly recommendable passion purchase.
