All 1 Known Issues
On the 2022-2025 Subaru BRZ, 2022+ second-generation BRZs (and twin Toyota GR86) have reports of rear differential whine or droning noise, particularly noticeable at 30-50 mph during deceleration and light throttle. The noise comes from the ring and pinion gear mesh in the Torsen limited-slip differential. While some gear noise is normal for an LSD, affected vehicles have excessive noise audible inside the cabin. Subaru released TSB 03-73-23 addressing differential noise with fluid replacement procedure.
Common Symptoms
- Whining noise from rear of vehicle at 30-50 mph
- Noise most noticeable during deceleration/coast
- Droning sound that varies with speed, not RPM
- Noise may quiet down after differential warms up
- Sound more prominent with windows up in quiet cabin
How to Fix
Have dealer perform differential fluid replacement per TSB 03-73-23 using Subaru 75W-90 GL-5 gear oil with friction modifier (Subaru SOA427V1710). The break-in fluid is replaced with the updated fluid and an additive that reduces gear mesh noise. If noise persists after fluid change, ring and pinion inspection and possible replacement may be needed under warranty.
