Collision Warning System Failure
Anyone had the Collision Warning System come on and tell you it is not working? Tried going into settings and turning all tabs off and then turn them back on but that did not help. Any other suggestions?

Here are manual suggestions:
"Cleaning the System
If the FCA system does not seem to operate
properly, this may correct the issue:
. Clean the outside of the windshield in
front of the rearview mirror.
. Clean the entire front of the vehicle.
. Clean the headlamps."

I don't have the feature on my 2021. But your manual has some suggestions for when its not working. But......its not clear to me that these apply if you get a message saying its not working. What did the message say?

I think many believe that Forward Collision Alert relies on radar. But in fact, depending on the vehicle, the system can rely solely on a forward looking camera, or both a forward looking camera and a forward looking radar.

So, you actually get a message when that happens then? What does the message say?

One thing you can try is what GM calls a Global Reset. Disconnect BOTH battery cables, touch the two cable ends together for a few seconds, then hook everything back up. You'll need to reindex the windows (the DIC even prompts you to do it), but won't lose anything else.
