I have a 2016 FR-S and sometimes the 3rd brake light makes a very loud vibration noise. I searched on the forums and found that many other people had this issue in the past.
Apparently, at some point Subaru started making the bottom bottom piece of the 3rd brake light with a strip of foam along the edge to stop the vibration noise. From what I read, since my car is a 2016 it should have this strip of foam on the 3rd brake light but it does not.
I checked the TSB thread
here and I can not find it. Does anyone know the TSB number for the 3rd brake light vibration noise?
It would be easiest if I can just go to the dealer with the TSB number and have them install the new piece. If there is no TSB or the TSB is only for Subaru or something, does anyone have the part number for the new 3rd brake light piece with the foam strip?
