Hi All, I’ve searched for this specific Issue but didn’t seem to locate any threads on this. This has happened a half dozen times at this point but the CMBS and ACC systems just randomly stop working. We would be driving or stopped, and CMBS and ACC lights would light up and we would get a notification in the app that systems encountered problems. The car doesn’t go into limp mode and all light go away with the restart. Before I take it in, anyone else had this and what might have been the resolution? Thanks in advance!

 

Likely radar issue. There will be code(s) so dealership should know exactly how to fix it.
