So a lot of you know that the radio on the Ascent defaults to 'On' even if you manually turn it off. When you turn the car on again it will default to the radio at whatever volume level you last used the car irrespective if you were listening to an audio book or your own personal music. I called Subaru America and they basically said they were aware of the issue but they considered it a feature not a bug. I'm paraphrasing but they had no solution, neither did the dealer. I stumbled onto setting the radio to Serious XM's station #0. Fortunately XM's station 0 is empty so it defaults to silence. It solved the issue for me. Hope it works for you.
