Lane Keeping Assist System Unavailable

[frankstallone]

About 15 minutes into my hour drive home today Lane Keeping Assist turned off on it's own on my '16 Sierra Denali. Attempting to toggle it back on produced the following message on my dashboard, "Lane Keeping Assist System Unavailable". I called onStar and they asked to see if their was anything obstructing the view of the camera on the windshield (by the rear view mirror). I said no it's a new car and even sprayed the windshield down via washer fluid before calling. For the rest of the ride home it was unavailable. Took a photo which I will post here. Can't find anything online related to the Sierra but found this related to the CTS.

 

Anyone every experience this? Brand new truck. Only a few hundred miles on it.

Follow up: It would appear to have been a fluke for a single ignition cycle.

When all else fails, do a hard reboot, AKA turn the truck off and restart.

 

Glad to hear you got it fixed. If it keeps happening, take it back in and have the warranty guys check it out.

Same advice I give for computers -- oh wait -- it is one. =)

I seen your response to a post someone said they rebooted the truck and cleared the problem. Mine did not. 
I just picked it up yesterday with 50 miles on it. Lane assist and The front distance minder show as not available. 
it’s a 2021 Silverado high country 3l diesel. 
 

thanks for any help.
