Overview

The 2021 Subaru WRX is a turbocharged sport compact sedan (also offered as a performance-focused WRX STI) designed for drivers who want everyday practicality with genuine rally-bred capability. It sits in the performance sedan segment alongside cars like the Volkswagen Golf GTI/Golf R and Honda Civic Type R, with standard all-wheel drive as a key differentiator. The 2021 model continues the VA-generation WRX (introduced for 2015), so it’s more of a refined, late-cycle version rather than a full redesign. It’s ideal for commuters who still want a car that feels eager on back roads, especially in wet or snowy climates.

Key Features

1) Turbocharged power: The 2021 WRX uses a 2.0L turbocharged SUBARU BOXER (FA20) making 268 hp and 258 lb-ft of torque, delivering strong midrange pull and quick passing power. 2) Standard Symmetrical All-Wheel Drive: Unlike many rivals that are front-wheel drive, the WRX’s AWD traction is a major advantage for year-round performance and confident launches. 3) Transmission choices: A 6-speed manual is the enthusiast pick, while a Sport Lineartronic CVT is available on select trims for drivers who want easier commuting (often paired with SI-Drive style behavior depending on configuration). 4) Performance hardware: Sport-tuned suspension, aggressive gearing (manual), and strong braking feel give the WRX a sharper character than a typical compact sedan. 5) Practical interior and safety tech availability: A usable rear seat and trunk make it a legitimate daily driver, and available driver-assist features (when equipped) add convenience for longer highway miles.

Common Issues & Reliability

Shoppers searching “2021 Subaru WRX reliability” should know the WRX can be dependable when kept stock and serviced on time, but it’s also more sensitive to maintenance and driving habits than a standard Impreza. The most discussed “2021 Subaru WRX problems” and “2021 Subaru WRX common issues” tend to include: 1) Clutch wear and related driveline complaints (manual models): Some owners report premature clutch wear, clutch shudder, or throwout bearing noise, sometimes showing up as early as 20,000–50,000 miles depending on driving style, traffic, and modifications. Hard launches and aggressive tuning can accelerate wear. 2) Oil consumption and oil level sensitivity (FA20 turbo): A number of owners report noticeable oil consumption between changes, and the turbo engine is less forgiving if oil gets low. Low oil can contribute to increased wear over time; issues can appear anywhere from 30,000 miles onward if oil checks are neglected. 3) Infotainment glitches and cabin electronics: Reports include head unit freezing, Bluetooth pairing issues, or intermittent backup camera behavior. These are typically nuisance problems rather than drivability failures and may be addressed with software updates. 4) Carbon buildup on intake valves (direct injection behavior): Because the FA20 uses direct injection, intake valves can accumulate deposits over time, potentially contributing to rough idle or reduced efficiency. This tends to show up more often past 50,000–80,000 miles, especially with lots of short trips.
