2023 Polestar 2: Reduced Performance & P0AFA Code After Charging

0

Heather Y. · rep 0 · May 22, 7:40 AM · 1 replies · solved · Question

Hey everyone,

I'm looking for some advice on my 2023 Polestar 2 Long Range Dual Motor. Yesterday, after a routine Level 2 charge at home, I started the car and immediately got a 'Reduced Performance' warning on the dashboard. The car felt sluggish, and the acceleration was definitely limited.

I managed to get it home, and using my OBD-II scanner, I pulled a P0AFA code: 'Hybrid Battery System Voltage Low'. I know the Polestar 2 is a full EV, so 'hybrid battery' sounds a bit off, but that's the code it gave. I've never had this issue before, and the car has been running perfectly.

Has anyone else experienced this with their Polestar 2? Is this a common issue, or could it be something simple like a software glitch? Any insights or suggestions would be greatly appreciated before I call the service center.
