Just saw a video on Youtube mentioning this problem. If all the bulbs are ok the module for the turn signals needs to be reflashed.

Might try one last thing, and see if reinitializing clears it up. Disconnect both batteries for a few minutes, then reconnect. Can't hurt to try.

So so odd and curious-

Sounds like a loose ground or connection somewhere.

I had this problem on my 2017. I took the outlets apart where the trailer plugged in and dried them and sprayed them with CRC Electro-Clean. I did the one on the bumper and the one inside the box. It cured it until I drove through a couple days of rain then it happened again. Blew them out with an air hose and sprayed CRC and it never happened again. Good luck, boomer
