Rear seat belt electrical noise?

Hey guys I’m new, however I’ve been using TacomaWorld as a helper for awhile now and decided to make an account due to an issue I just ran into. One of my rear seat belts on my 2019 TRD Off-Road Tacoma has just recently started to have an electrical sound coming out of it at the top where the belt feeds from. The sound also is only heard when the truck is running, once I shut it off the sound stops. I have a video of the sound but I’m unable to attach it. I’m willing to text the video to anyone who wants to hear it, just send me a message on here. If anyone has ran into this before or has any suggestions on what may be causing this issue I would appreciate the help before I have to take it into the dealership.

 

Did you ever find a solution to this problem? My 2017 TRD just started doing this same thing.
