I think that is BS. Total speculation without any facts. I get the same issue in my 2024 AT4x HD. I have no leaks. It is general condensation that forms in cold temps. It does not indicate an external leak. Warm air cooling in a confined space will produce condensation. If I remote start mine for 5 minutes before getting in at 4 am no issues. If I don’t remote start I get the message for about 5 minutes of driving until my windshield fully defrosts then it clears. All cars manufactured have defrost for a reason and that is not a leak. If you have any fogging it will produce that message as the camera looks though the windshield. Remote start your truck, run it for a while on cold days, or take the plastic cover off and apply antifog in that area. Not an indicator of a major issue.
