Did your dealer offer to let you test drive the car at home? How was the experience? When my son called our local dealer, they didn't offer home test drives, so we had to go to the dealership instead.
That's frustrating! I haven't experienced those problems either. You might want to talk to your dealer and see what they think. They might be able to diagnose the issue. Also, have you checked for any software updates for your car? Sometimes that can help.
My bike rack requires a 2'' receiver, but the Polestar came with a 1.25'' one. I had to purchase the 2'' hitch, along with a ball and an adapter, to make it compatible.
