Intermittent Problem with Electrical (?)

We have a 2018 Jeep Wrangler JK - 2-Door. At times when driving down the road, for no apparent reason, we will here a quick beep sound. When that happens the red “brake” light on the instrument panel flashes one time very quickly, the speedometer quickly falls back toward "0" and then returns to normal, and the cruise control goes off. This happen very intermittently and seems to have no effect on driving other than disengaging the cruise control if it is being used.

Any advice/suggestions as to what may be causing this will be greatly appreciated.

Check your battery terminals and make sure they are tight.

Did you ever find an answer for this problem. I am now having the same ting on my 2013 Jk Rubicon

The problem is becoming more acute.The dash panel is periodically flashing, all at once for about a second or two, the follow lights:

ABS, Brake, ESC along with the speedometer falling to zero. The tach stays on and the engine continues to run with no hesitation.
Ran codes and got nothing.
