I bought a used 2022 Polestar 2. The car keeps slowing down for no reason on the highway, even when there are other cars nearby. I'm not sure if I can trust Autopilot anymore. It's happening more often. It doesn't seem to be a problem when there are fewer cars on the highway. I checked the software and it's running 1.9 version. Asked him prior to the update if he encountered this issue but he said he did not. Maybe the software version is causing it.
