A couple of days ago while driving on the freeway I suddenly got two messages that popped up. One says "park assist unavailable" and the other says "parking sensor(s) may be obstructed." Doing some checks online suggestions were to clean the sensors and reboot the software. I've cleaned all sensors and cameras as well as rebooting, but the message remains. In the service menu all of the sensors and cameras show as green, so nothing obvious stands out. I did install the auto-frunk last weekend and plan to check all of those connections and anything near that this weekend before I set up a service appointment. Anyone have any other suggestions to look at?
