My RAV4 Prime is much louder than an ICE at low speeds, especially in reverse. It’s so loud it’s sparked a bunch of videos and discussion on how to lower the volume: https://m.youtube.com/watch?v=q1UqicqdzFE

Some have figured out how to disable it completely (just pulling the noisemaker causes a fault code to trigger) but quieting it down to roughly the volume of an ICE seems more reasonable to me.
