One problem related to horn assembly has been reported for the 2016 Jeep Renegade. The most recently reported issues are listed below.
Mileage began flashing. Called dealership, unknown. Random lights illuminating on dash that lights and turn signals were "out" but they were working properly. Shut off vehicle, restart and dash warning lights were gone. At 36000 miles my drivers side rear light component not working. This includes tail light, back up light, break light. Unassembled connector and noticed the middle port appeared melted and black soot noted around the pin on the light that the pigtail connected to. Called dealership to explain, they state I have to pay the diagnostic fee ($120) then pay for labor and cost to fix what they find. Dealership states vehicle is out of warranty for electrical system. Obviously there are many electrical failures. Also I have encountered the stalling of my vehicle twice when turning left and trying to accelerate. My emergency horn went off in the driveway. My sunroof was closing extremely slow (as if it were a motor issue) but worked fine after shutting off and turning vehicle back on. "serv 4wd" displayed once.
