Some Subaru WRX owners report experiencing a squealing noise at idle, particularly when the clutch throwout bearing is weak. This noise typically disappears when the clutch pedal is pressed, indicating a potential fault with the throwout bearing. Owners may also hear a whistling sound under the car or in the engine bay when the clutch pedal is engaged, which usually stops when released. In some cases, the noise may stem from the clutch release fork vibrating against the ball joint, with the vibration ceasing when the clutch is engaged. It is important for owners to be aware that powertrain warranties often do not cover the throwout bearing, as it is considered a wearable part. Additionally, misfire codes and tuning requirements for aftermarket parts can also affect the vehicle's performance. For those experiencing these issues, consulting a qualified mechanic for a thorough inspection of the clutch system is recommended.
