Curious if this has happened to anyone else...

you can change the sensitivity from early to late and back via system settings but the alarm no longer actually works when crossing a median or line.

the parallel lines indicator on the display no longer shows up

the button on the steering wheel no longer does anything.

If I remember correctly, my manual is not available, on the end of the turn signal stem, pressing that button will activate the system.

Agreed- end of stalk toggles it in and out with confirmation on the center display. The button on the steering wheel is for smart cruise control where you select the sensitivity (again confirmed on the display). It uses the same hardware but different function altogether. Hope this helps and, as you would suspect, there's a video for that!

I ended up resetting the computer to factory default and this solved the issue - and your right re: button on the end of the turn signal - thanks!
