Autonomous Emergency Braking (AEB) and Lane Keep Assist systems turn off for no apparent reasons. This happened multiple times on this loaner vehicle and my own vehicle (same model). All the times I’ve seen this happen it was at night and clear out. So its not like radars or cameras are blocked by rain, snow, etc…This needs to be investigated since its happening on all of these models and radar/cameras are clear. Only common theme so far is that its happening when its dark out.
