Thanks for this information, my 2022SoulEV has the same noise as the 2016 posted here, I will take this info to the dealer.
It is pretty loud, and I my wife's 2019NiroEV (much more refined) doesn't make any of the sounds.

Hi Gordo, I am sorry to hear that.
I just wanted to provide a quick update on this:
I contacted a local dealer and they verified there is an update for the vehicle. The update was applied, and appears to have rectified the inoperative heat pump problem. In testing the heat pump at an ambient outside temp of approx. 8C, inside cabin temp set to 20C to 22C, the heat pump is working as it did prior to update SA427. After all of that, what a relief!
Furthermore, testing in the garage by chilling the outside air temp sensor down one degree at a time to as low as -20C, cabin temp set to 22C confirms that the heat pump continues to operate throughout testing (prior to that, once ambient sensed temp dropped below approx 15C, the heat pump would not operate, at all).For information purposes, the update is listed by Kia Canada as "Service Action 210031", released April 23, 2021.
The text of the update indicates:"This bulletin supersedes Service Action # 200042 and provides the procedure to update the Battery Management System (BMS) and Full Automatic Temperature Control (FATC) software on some Soul (PS EV) vehicles to improve air conditioning operation while the battery is charging.
To correct this concern, update the BMS & FATC system using KDS event #501 and event #540"
