Same issue cropped up for me last week (2022 P2/Pilot/Plus received in February).
SOS eCall Service Required error message was the first indicator, every time I got in the car for a day or two. Then the keys stopped being recognized unless I put either the main fob or the activity key in the cupholder under the armrest - the app/PAK stopped recognizing any data from the car. I could drive, but I couldn't lock the car - the remote key fob buttons didn't work, PAK wasn't connecting, touching the door handles did not lock the car like normal, and with the hatch open, the close hatch button worked but the close+lock hatch button gave a beeping rejection and wouldn't close.
I decided not to wait any longer for a lower battery state of charge and risk this happening again when I have even less time to deal with it in the future, so called Polestar main customer service last weekend and was told this issue is an "automatic tow" and that I shouldn't drive the car anymore.
Credit to Polestar, they arranged towing promptly to the Los Angeles service center (aka Galpin Volvo in Van Nuys). However, the national help line couldn't tell me how long things would take and deferred to the service center, which was closed over the weekend. Because it was delivered on a weekend with no one there to receive, no one at the service center discovered it had been delivered until I finally reached a live person at the end of the day, after calling several times throughout the day on Monday. It's now close to end of day Tuesday and the only real information that I have is that they are "backed up" on Polestar service and it might be a week before they can look at the car. Wish I'd known that before agreeing to a tow to that location. I've been promised a loaner (more likely a rental car from Enterprise rather than a Polestar loaner that was promised during the sales process, but I can at least understand the supply chain/demand issues there...) but still no directions on how that will work.
