I have the exact same experience with an EX30. Their entire line of full EVs is a disaster. I will never buy a Volvo again.
I sat in an EX90 demonstrator a year ago at the dealer and was told not to touch anything inside the cabin. The car wasn't ready back then and, from reading owners forums now, it's still not fully baked.
I don’t understand the logic of having each Polestar model running a unique software stack rather than progressively improving one system across all models - but must be a downstream impact of the fractured Geely badges.
They did recently issue a software recall for the backup camera, so now when the backup camera crashes it goes into 360 camera mode instead of just a black screen.
Overall I'm happy with this car though and would recommend it.
