NHTSA Complaint #11685802 — 2021 POLESTAR POLESTAR 2

On September 7, 2025, I had a total failure of the forward looking radar system in the vehicle. The symptoms were an error "Collision Avoidance system unavailable" and symbol on the driver display after starting the vehicle, and attempting to activate cruise control (which is typically adaptive cruise control) results in an "Unavailable" error. The symptom occurred suddenly after an otherwise unremarkable drive cycle, and the radar sensor appears to be free of any obstructions. This renders an otherwise key safety feature of the vehicle in reducing the chance of a forward collision completely inoperable, and due to service backlogs, I am unable to have the issue addressed by the dealer/service provider for at least a month, meaning the vehicle will remain stuck in this state until then. Prior to this, I have received "Camera temporarily unavailable" errors when in reverse (inhibiting the backup camera feature from operating as intended), even after updating to the latest software version as indicated by the most recent safety recall notice. I've also received very intermittent errors around the blind spot sensor/rear auto-brake/park assist system -- and these three errors occur at the same time -- but I have not seen this error either in the days before or after receiving the collision avoidance system unavailable error.
