my car has an AI assistant. I don't know what the wake word is, but it will wake up and be useless with no obvious way to turn it off. I'm sure I could search for it, but it happens while I'm driving and I forget about it. It happens just infrequently enough to not remember, but often enough to be really annoying.

My wife turned on a meditation feature on our very old Alexa. I guess the app was deleted or something, but every morning Alexa turns on and says "Starting your meditation times ... Sorry, this is no longer available". If I tell Alexa to turn this off, it has no idea what I'm talking about and it shows up nowhere in the iOS app. Instead of meditation, I got a nice dose of minor annoyance every morning.
