We tow a 2016 Cherokee Trailhawk with no problems. We had to have a Mopar wiring harness installed at our expense ($800 in Canada). The other thing you have to be sure of is that your vehicle has Active Drive II. I don't know a lot about this, but we came close to buying a different model and by chance discovered it was Active Drive I and apparently it cannot be towed. Check carefully in the owner's manual - DO NOT trust the sales person - they are only trying to make a sale and often do not know anything about towing.
It cost us $3000 to set up our Jeep for towing. If we hadn't invested this money in it, we would have got rid of it. We do not particularly enjoy this vehicle but are stuck with it for now.
Do your homework!
