The pedestrian warning system and horn are speakers in newer Tesla’s. The speaker is in the front right ahead of the wheel facing down towards the road. When it is raining or snowing, rain or snow get lodged into the speaker and it is completely inaudible. I stood 4 feet away from my vehicle and had someone honk the horn and couldn’t hear anything at all. This is very dangerous. The pedestrian warning system is complexly inaudible also. Issue persists for approx. 2 days after rain. If it continues to rain for several days, the horn ds not work the entire time. I have contacted Tesla support and they state there is nothing they can do to fix it since it is how it was designed.
