I was in for P2097 and they did this at the same time.Campaign #39570: Service Update - Front Camera Freezes
A Service Update Bulletin was released last month for possible issues with the camera features such as Lane Keep Assist LKA) or Forward Collision Alert (FCA) delivering driver warnings when not near the lane lines or without an object in front of them. There is a software update for the forward camera module to address the issue.
This pertains to CERTAIN 2016 and 17 Volts with FCA/LKA
THIS IS NOT A RECALL
Like most service update campaigns GM will not be notifying owners but the service (if necessary) will instead be completed on your next service visit.
SOME dealers may call Volt owners they have worked with in order to perform the updates
If you wish to determine if the update pertains to your car you can call the Customer Support Team OR call your dealer with your VIN
FCA is deactivated after the update is applied. If the cruise control is on,* pressing the FCA button just gives a warning that FCA is deactivated. Turning off cruise control allows you to re-activate FCA and then everything works as normal.
This is probably in the manual, but it provided a couple of minutes of frustration for me and I'm still not sure why FCA activation is connected to the cruise control.
* I don't mean "engaged", but just "on", i.e., the cruise control icon is white.
