message appeared and the accelerator stopped working. We had to leave the highway, stop the vehicle, and restart it before the accelerator worked again. I retained a screenshot of the warning message from this event. Second incident: On 1/31/2026 at 4:26 PM. The battery ran out and the vehicle switched from battery power to gas.

Restarting cleared the warning and restored accelerator function. I retained a photo of the error message and dashcam video showing the vehicle speed and rapid deceleration.
