I have a 2017 CTS 3.6. I recently had the Cue infotainment system completely replaced beaches it was constantly rebooting. After it was replaced it worked correctly for about a day. Then it started doing the same thing. I’ve done the hard reset. Still the same thing. I noticed it starts doing it when tried to connect to my iPhone. So I turned off the Bluetooth and everything works fine. Any ideas why the Bluetooth may be causing this? This happened with my iPhone X and now my iPhone 11Pro.
