I can not locate the old thread but I believe another member mentioned he had pedestrian warning on his early Model Y. Last night I went to the store and when I reversed out of my spot it was making the pedestrian warning sound. It has never made the sound before till last night. This morning I went to record it too post here and no more sound. I was able to look online and locate were the speaker is on a Model 3. I pulled back the plastic and there is definitely a speaker there. Any idea how to turn it back on?
