Yesterday I got in my car with 90% SOC. Just downloaded 40.2 I heard a very strange noise. It was a very quiet, low pitched whine that went higher in frequency and then cycled back down to the starting frequency, much like a very quite police siren. At first I thought it was some external noise. I drove a block or so and stopped at a stop sign and I heard it again when all was quiet. After driving for a bit I did not hear it again. I have not seen this noise posted in this forum previously. Anyone else have the same experience? Oh, my car is a P3D. Thanks.
