On-board AC charger failure. Confirmed by dealer, parts on 4-6 week backorder. System gave two different messages. One in the driver’s display reading ‘AC charging fault; Book a service’ and a separate message in the main display reading ‘Critical Issue: Charging fault; Charging not possible’. These appeared at around 3,400 miles, and while connected to a level 2, 40amp, charger. Attempts to use any form of AC charging after this would not initialize. This issue has been reported by MANY other Polestar 3 owners in the US and globally. There are also several NHTSA manufacturer communications related to this problem, such as DP1035, DP1037, and DP1038.
