My transmission is being fully replaced under warranty at a dealership. It sounded like a loud whirring or flapping that disappeared above 40km/h, but was loud at low speeds, especially when coming to a stop. Sound was wheel-speed-dependent, not RPM-dependent. Noise was present in D, N, and R. Noise was not heard at a standstill. Loudest at 10km/h. On the hoist in D, sound was obviously from CVT box, not any specific wheel. The sound reminded me of when we used to attach a baseball card to our bike as kids, so that it flapped in the rear spokes as we rode. I had no perceivable loss of power—just the sound. Subaru does not attempt to rebuild the CVT. They just remove it and replace the entire unit. Makes me wonder about the reliability of these CVTs, especially after the big warranty extension recall on the older CVTs. Not thrilled with this 2020 Forester Limited so far.
