I just got a 2023 Limited Ram 1500 last month. Every once in a while, I hear a hissing sound from the back. It is there if the truck is on but moving or not does not make a difference. The sound system is of course turned off. Initially, I thought it was coming from the rear speakers. When I got to the backseat, I cannot figure out where it is coming from. Then I thought may be it is the air from the air vents. Well the climate is also turned off. Any ideas?
