One problem related to wiring has been reported for the 2016 Jeep Wrangler. The most recently reported issues are listed below.
The wheel speed sensors are notorious to give out in these vehicles. Even at low mileage. The abs and traction control lights come on limiting performance and causing issues requiring immediate service. Their are many Jeep owners I have encountered with this issue and it can be either location or inappropriate guard to cover wiring. Jeep states it is part of maintenance but a simple plastic cover would alleviate a lot of the issues that may be associated to debri or causing faulty.
