2017 MKC computer goes dark and restarts

Afternoon everyone.

I have a 2017 MKC Black Label with 13 K.
My wife and I brought it used, this last Christmas.
And except for the following issue, the vehicle has performed flawlessly.

I should very much appreciate advice ...

My wife is a Realtor and uses Navigation frequently.
She likes the navigation app.

Twice now (over the last two week) when my wife is using navigation the Sync system goes blank for about 30 seconds after which the Black Label screen appears and then things seem to work fine once again.

She has entered a specific address to navigate to before the Sync system goes blank and she needs to re-enter that address after Navigation is active once again.
(So, it doesn't seem to be retaining things once the systems goes blank.)

The version of Sync 3 in the MKC is Version 2.0 Build 16074.

Before I make an appointment with my dealership, I was wondering if anyone else has experienced such an issue.

And, I was wondering if anyone might have advice as to how I should proceed.

We like this vehicle a lot.
This is so odd.

Thanks in advance for replies

At a minimum it's rebooting Sync.(just like you see it when you start up) it could be crashing and rebooting. Have the dealership update Sync and see if it resolves itself. Current version 3.x.

I don't have a BL but I assume the computer is all the same, minus the startup graphic. I have experienced that once in a while, maybe once in a couple of months of so, maybe a quarter. Usually, when it restarts, or if I power cycle the car, the problem goes away. This last time, the screen locked up and everything froze on the touch panel, it wouldn't even shut off when I turn off and lock the car! I had to soft-reset the car (holding down the radio power button + next track button until the screen reboots).

I like the car, the SYNC software needs work for sure, but I would say it's about 95% stable.

Thanks for the replies.

On Wednesday afternoon last (July 10th), the air conditioning stopped working.
My wife, who was driving at the time, pulled over and called the dealership.
They (a person identifying himself as a mechanic) talked her though a series of procedures but none were successful in getting the ac to begin working.
Although later that evening, I started the automobile and was able to start and run the ac without issue.
While on the phone, she mentioned the issue with sync going blank.
And based on Buckeye's suggestion, asked if an upgrade to sync might be in order.
The mechanic said the blank screen business happen all the time (neither my wife nor I expected to hear that) and suggested she bring it in and they will looks things over.

Anyway, my wife took the automobile to the dealership the next day.
They gave her a 2019 MKC to use while her's is being worked on.
(I like the fact that the 2019 shows the actual tire pressure for each wheel. Our 2017 doesn't do that.)

In a status report on Friday from the dealer, they indicated a sync upgrade was performed and it is now at 3.X.
And they also did "something or other" to the ac for both the driver and passenger sides. (Not sure exactly at this point.)

Thanks Buckeye for the sync upgrade suggestion.
And thanks Starzplacez, for the tip about the soft-reset. I've made a note of it in my MKC folder.
