2023 R1T - Horn stops working whenever it rains

[MookieMV]

The normally anemic R1T horn turns into a squeaking squirrel that you can barely hear after it rains. I took the truck to the Brooklyn service center and they "fixed" it. But two nights ago it raind and now I have no horn again. Am I the only one with this issue? Is it a defective horn or bad design? What can be done to fix it for good? Thanks!

Water being ingested into the horn causing corrosion and rust buildup. The diaphragm is a metal disc. Rivian had the horn(s) point forward, which makes ingesting likely and not drain well. Owner Guide had a warning and guidance about it in context of water crossings (few blasts after crossing to evacuate water). IIRC, one of the rolling changes over the years was to move the horn to the passenger side where it’s more shielded. Orientation might have also changed.
