I've seen something similar when snow is blocking the radar. Lots of alerts and those three --- when the dialog box goes away. As long as I have the car on, CC continues to work (I only use standard CC so I'm not sure what happens with ACC). But if I turn the car off, I have to remove the snow before the CC works again.I have a 2021 EV. The cruise control works fine but no longer displays the speed it is set to - only see ---. Any ideas how to change this?
