I had the same issue with my 2014 fixed under warranty. First they replaced the camera $$$$. Issue not fixed so they traced it to one of the interior lights, I think they ended up replacing sun visor with the light.
I would suggest you unplug the visor and see if it is fixed. Sorry I cant be more help but I did not DIY it.
