Heard a crunching / knocking sound, as if there is some gravel or stones stuck in the rear suspension. I heard it first thing in the morning right after taking my car out of the garage. The sound continue for a while even after stopping the car and turning the engine off. I was so occupied that I forgot to make a video.

Now the noise is gone and all my tire pressure are also fine. Not sure what caused it or if our cars need a software update. I will have it checked by the dealer probably next week.

Has anyone experienced this or have any knowledge about this type of a noise? Could it be the differential? Please share, thanks!

Sounds just like a stone stuck between the brakes and the wheel. Probably just knocked it loose which is why it sounds fine now. There is another thread on the a couple away from yours that sounds identical to what you are describing
