On the 2022-2025 Subaru WRX, owners of the current WRX have documented a pronounced rear driveline whine or howl, most noticeable during steady-state cruising between roughly 45 and 75 mph. Reports commonly describe the noise as coming from the rear of the vehicle and changing with road speed rather than engine rpm, pointing to the rear differential or final drive. Some vehicles improve with fluid service, while others require further dealer diagnosis for gear pattern or bearing issues.

Common Symptoms

whining from rear of vehicle
howling noise at 45-75 mph
noise changes with road speed not rpm
driveline hum during cruise
rear-end noise on deceleration or light throttle

How to Fix

Road-test the car to confirm the noise changes with vehicle speed and load, then inspect rear differential fluid condition and level. Dealers typically compare against another WRX, check for abnormal backlash or bearing noise, and may replace fluid, bearings, or the differential assembly depending on findings. Rule out tire cupping first because aggressive OEM tires can mimic driveline hum.

Medium Confidence

On the 2022-2025 Subaru WRX, multiple VB-generation WRX owners have reported oil leaking from the turbocharger oil feed area, often traced to the banjo bolt or sealing washers on the turbo oil supply line. The leak typically shows up as a burning oil smell after driving, light smoke from the engine bay, or visible oil residue near the turbo and exhaust-side components. Because the leak can drip onto hot exhaust parts, owners often notice it early even when oil loss is modest.

Common Symptoms

burning oil smell after driving
light smoke from engine bay
oil residue near turbocharger
small but repeated oil level drop
smoke visible near passenger-side rear of engine

How to Fix

Inspect the turbo oil feed line, banjo bolt, and crush washers for seepage, especially around the turbocharger and upper engine rear area. Repair usually involves replacing the sealing washers and re-torquing or replacing the affected fitting/line; any oil-soaked heat shielding should be cleaned to prevent recurring odor. After repair, verify no fresh seepage appears after a full heat cycle.
