2021 Polestar Polestar 2 Fuel system Problems

“The vehicle was serviced on 2/13 at the Polestar service center in Seattle. I believe this is when software version 4.2.13 was installed. In the last week, I've noticed a new behavior.

The worry comes with failure, as this is a braking component, failure while braking would be highly dangerous.”
