For the past 3-4 weeks while driving, the cue system will start to beep, change pre-set radio channels and the screen will freeze up. the beeping still continues. after a short period after turning the vehicle off it is fine but begins the same symptoms after about 5-10 minutes of driving. i brought the car to the dealer where they made it appear that they had little or no knowledge of any problems. i informed them i've been in the auto repair business and am very familiar with all the cue complaints. the car was kept for 4 days and then i picked it up. i was told it was a simple software update which i replied to the service advisor that i didn't think so. (i guess my experience in business means nothing!). i drove away only to have the same issue after about 5-10 minutes of driving. it took 2 weeks to obtain another appointment at the dealer. i asked if they have the part and was told that the part was a special order, blah, blah, blah... but what caught my attention was that the service advisor said the part has to be ordered from a third party. not gm. this may be the reason there is no recall yet. i'm returning the vehicle on 12/17/2018 and would love to be able to add to this after the outcome which i was told would take about 4 days.
Cue radio, climate, navigation, bluetooth system keeps freezing up. now the screen has begun to spider crack. this is a very common problem amount all cadilac's models using the cue system. it is strange that they haven't a recall and fix.
