2021 POLESTAR POLESTAR 2 Forward Collision Avoidance Warnings Problems

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),...

Upon entering the vehicle and starting a drive, inexplicably, no audio sounds were playing inside the vehicle. This includes the infotainment system but also the turn/hazard signal clicking, and likely any additional audible alerts that are necessary to drive safely in all conditions. Volume control did not make any difference. Restarting the infotainment system by holding the home button on the screen bezel for 30 seconds, while still driving the vehicle, and waiting longer for the software to reboot, eventually fixed it. There are additional reports of this online.

This car will periodically lose all interior audio function. This includes safety alerts like parking, forward collision, rear collision, cross traffic, and any other alert you can think of including the sound the turn signal makes. Bluetooth audio and radio also unavailable. This is a commonly documented problem as noted by Polestar enthusiasts on Reddit and other forums. Some can fix the problem by performing a reset of the infotainment system. I have had instances in which resetting this system made no difference. The car was unfit by US safety standards until the next day if lucky enough to see the issue self correct. I have only had this car for 4 months, but every week or so this issue has happened at least once. This is an unrecoverable safety issue with risk of assumed safety features arbitrarily not working.
