Rivian says “fat finger” caused software update to brick infotainment systems, physical servicing may be required::Today’s cars are more like computers on wheels, and even a seemingly routine software update can lead to unexpected consequences. Rivian unfortunately experienced a “fat finger” mishap with their latest software update, bricking infotainment systems […]
There have been some experimentation but the best (IMO) option is hitting the SOS button to call and navigating the phone menu to get to a representative, not emergency services and having them disconnect your car. You may need your VIN, you’ll need to confirm that you do not want connected services and it may take a day or so to take effect. Now, my SOS button doesn’t have the green light and while the radio - according to the infotainment - is still powered, it is no longer connected to the network.
Another way if you don’t plan on using the microphone (like for calls) you can pull the DCM fuse but I prefer the above option.
