I have an intermittent problem with the park assist feature. For a while I was getting a message that said, "Service Park Assist". Now I hear some chimes, but there isn't a message. I know what it's talking about though. Maybe I selected "dismiss" and now the message won't show anymore. What happens is when I start the car the park assist fails to initialize and won't work after that. Sometimes the little LED next to the P doesn't come on. Sometimes it does but it still won't work. About a quarter of the time, or less, it does work. I'm wondering if anybody knows if this is a software or hardware problem. I'd say it's hardware. I plan to set up a service appointment for it.
