Never mind. It's fixed now. Just restarted the car and it went away. !
 
If it happens again, be sure to post details: year, miles, relevant mods, driving conditions when the message showed up. OBDII codes if you have them.
 
That happens w/ mine every few days when I first start the car; mostly if I haven't driven it for a day. It always goes away after I've driven it somewhere and stopped; it doesn't happen again that day.
I'll check the gas cap as discussed in other threads. No issues with driving, just no cruise control while the lights blink.

Interesting. It happened again today. So I restarted the car and it went away.
Let's see what happens. I will also try to get the fault code.
 
This happened this morning to my wife’s 2016 570 with 87k miles. Hoping it will just go away as well after restarting. Never heard of this before.

How is yours doing after the last 10 days?
 
This sounds like the CDL sticking issue. The truck runs a self test at start up and fails when diff is cold. Works fine when warm. Are you exercising your CDL and 4Lo actuators enough?

It has not happened since last time which was about 10mdays ago, then again I have not driven much at all for past week.

Ok, thanks everyone. I’ll start exercising the LO function a couple times a year to keep the actuator working properly.
 
Wheel speed sensors can cause this…along with a gozillion other bits…
