I was really hoping someone had a solution for this already. I have a 2011 lgt with the same issue and I used to be able to turn car off and it went back to normal but then I took it to local Subaru and they said they couldn't find anything and might be glazed rotors which made no sense to me with the symptoms and now it is soft with little breaking power all the time instead of being intermittent issue.
