2018 XTS Luxury, 2001 STS, 2006 DTS, 2007 Escalade EXT (son's)
So I have a 2018 XTS Luxury and it's been to the dealer once for the navigation screen going black, they said they could not repeat it. Well now it's happening more often, actually I have a video of this while it was happening. It is going to the dealer next Tuesday (a week from today), looking for suggestions. So when this happens it only effects the navigation, I can switch to any other screen and they work fine. It was only happening on a startup, but today it was working fine then just went black while I was driving. I came out several hours later and it worked fine. I bought the car a few months ago checked the vehicle history and it was only in for recalls, it is almost out of warranty so I am a little worried about it not being fixed. I read a few posts but no one every comments what, if anything, fixed their problem.
