Subaru WRX Power Steering Service Malaysia
The WRX uses an electric power steering (EPS) system, eliminating hydraulic fluid maintenance. However, the steering feel is a key characteristic of the WRX driving experience — any reduction in assist, unusual noises, or pulling to one side should be investigated promptly. EPS faults often appear as steering-related warning lights or error codes in the EPS control module, which requires a full diagnostic scanner to read. Wheel alignment directly affects steering feel and tyre wear, so combine any steering complaint investigation with an alignment check.
Subaru WRX Power Steering
- WRX EPS: VA WRX (2015–2021) uses electric power steering; sport-tuned for quicker response; WRX EPS has less assist at highway speed for direct feel; Sport# mode reduces EPS assist further for sportier drive
- WRX torque steer: FA20DIT front AWD WRX has some torque steer at full throttle from low speed; if torque steer is excessive — check front CV axles, tyre balance, and engine mounts; torque steer on WRX is normal in small amounts
- WRX EPAS warning: if EPAS warning on WRX — check battery voltage first; low battery often causes EPAS faults; charge battery, reset EPAS via SSM4; if EPAS returns after full battery charge, diagnose torque sensor or EPS motor
- WRX steering rack: EPS rack on VA WRX is sealed unit; if steering has clunk or play that survives alignment check — inspect tie rod ends first (common wear at 80,000 km), then steering rack; tie rod ends are user-accessible for inspection
