On January 9, I was driving my new 2025 Rivian R1S (approx. 2,400 miles) when it suddenly displayed Drive stalk not working. The vehicle jolted, made a loud noise from the front axle, and then fully stopped in the middle of a busy road with the battery still at 55%. Once it stopped, I had no hazard lights or power steering, and the infotainment system locked up. After several attempts to reboot, the screen showed Critical battery error before shutting down completely. I was unable to move the vehicle or alert other drivers with flashing lights, creating a major safety hazard. It took about two hours for a tow truck to arrive. ## Component or System Failure: The vehicles propulsion system (drive controls) and electrical/hazard light systems appeared to fail simultaneously. The vehicle is currently at a service center for inspection and could be made available if needed. ## Safety Risk: Being stranded in the middle of the road without hazard lights or any way to move the car put myself and other drivers at serious risk. ## Reproduction/Confirmation: It has not been confirmed or reproduced yet by the service center. ## Inspection: The manufacturers service center is inspecting the vehicle. No other parties (police or insurance) have inspected it. ## Warning Lamps/Messages: There were no prior warnings. The Drive stalk not working error and subsequent Critical battery error appeared just moments before the vehicle stopped. I am reporting this because a sudden, total shutdown without hazard lights is a serious safety concern, especially on a busy road.
