First, I already have a service appointment scheduled for next Friday on an unrelated issue...I will be asking about this when I take the car in. I got my Model 3 this past Saturday and I already have 600 miles on it (I drive nearly 90 miles a day for work M-F). I was looking through my garage Nest cam history and viewed a clip of me reversing into the garage. That's when I noticed an odd chirpy squeaky sound occurring when I'm backing in. Sounded like a bird made it into my garage. https://photos.app.goo.gl/xrwv7REqscyKHAr86 I went back out to verify the noise by driving out and backing in again, this time I left my windows down, and yep, it was making that noise. At first I thought it could have been tire noise against the garage floor but it was occurring even when reversing on the driveway outside. I don't really notice it when driving forward. As you notice in the video, I'm not applying the brakes as I'm reversing. Looking back further in my nest history, it certainly wasn't making this noise the first 4 days I've had it. Anyone have any ideas what this might possibly be? The car seems to drive fine otherwise. The only other odd noises are coming from the creaking aero craps when at low speeds.
