   On occasion, staring yesterday, I get an odd (maybe buzzing) noise when the car (2020 Ultimate) is standing still. Turning the car off, and then on again, does away with the noise. It may or may not recur on a subsequent startup. While a recording is attached, it does change in frequency if left alone on startup...I haven't let it run its course to see what happens, it's very annoying.

   What's the ambient temp? It sounds mostly like an unhappy AC compressor.
