Moaning, buzzing noise of front differential when acceleration to 35mph, also upon deceleration, especially when car is hot.
Clunking/thud is heard from the rear/under carriage. To duplicate the issue, it must be driven 30-40 min so that differential oil is hot and drive up to 30 mph then slow down to below 10 mph to confirm the issue. The issue is limited to 2019 Rav4 (with torque vectoring system - only adventure and limited trims) no known TSB to fix the issue. The sound is more like a heavy object (like a bowling ball) is dropped on a carpeted floor and like a muffled sound rather than a sharp mechanical gear rotating sound. The noise is more like a thud and very prominent enough to distract driving. It happens after awd is engaged by falling the vehicle's speed under 20 mph in eco or normal mode. It does not happen in sport mode where awd is engaged in full-time.
