when on cruise control sometimes it will drop off .

What is your question?

When it drops off I hear a warning ding. Around town I will hear this ding and when it happens the speedometer always seems to be going back up to the correct speed. It dosn't seem to effect the power to the engine as I have been accelerating and heard the ding and felt no hesitation.

How long has your 2016 Jeep Wrangler had this problem?

one month
