I am again driving a loaner. I have had XTS Platinum in several times to dealer. Problems have been with CUE, ie: keeping phone paired, navigation system, voice recognition, etc. Three days ago, the CUE system broke down completely. CUE would start to intiate, then icons would come up, then would go black, then screen would come up in computer block letters saying "system initializing", then it would eventually go to icons, which again would not work. It's like it's caught in a loop and can't reboot.
Dealer service says diagnostics showed losts of defaults in old stack and none in new stack, but problem remains.
On top of that, while the radio works, it tends to go out when the CUE goes black. The backup camera also goes out.
Dealer who claims to have been in contact with Cadillac has had my car in several times and even replaced the "stack", which I assume is the center computer system. That has not changed anything. So, they don't seem to know what to do. They still have my car and say the earliest the Cadillac service rep will be in town is next week. So, that will be at least 9-10 days I haven't had my car in the 56 days I have owned it.
Has anybody had similar problem and if so, please relate, so I could tell my dealer what to do before Cadillac gets around to getting back to them?
