Unfortunately computers hic-cup once in awhile. This is true of the one on your desk and the multiple ones in vehicles.
If the problem you experienced has not returned, and everything else is good, I wouldn't be concerned. That doesn't mean the vehicle will be 100% trouble free. But there are no guarantees another one will be trouble free.
I had some issues early on. I have to make an appoint soon, for an oil change. I've had no reason to visit the dealer since February.
Congrats, and enjoy your new Jeep!
Stay clear of "The Sky is Falling" crowd. Their leader, Chicken Little, can ruin a good night's sleep.
