What you are experiencing is actually not terribly uncommon on Nissan vehicles like your 2018 Frontier. There is a dedicated relay for the trailer running light circuit that should be located in the fuse box inside the cab. I simply recommend checking to see if that relay is missing or if it has gone bad. If so you can use one of the blue relays from the Curt Relay Kit # C57000 and the issue should be resolved.

I have attached an image of this relay location along with a helpful installation video that you can check out as well. You can watch the installer insert the mentioned relay starting at about the 4:15 mark. Please let me know if the issue persists and I will be happy to look into this further.
