I was driving along the road at 35 mph when the vehicle lost power and refused to accelerate or keep speed. The cluster flashed a warning indicating ‘Stop Safely Now’, so I pulled over and came to a stop, and I shifted to P. Thereafter, the vehicle shut off and would not start, continuing to indicate to ‘Service Vehicle Now’, as well as additional new errors, including ‘Service Powertrain’, ‘Full Accessory Power’, ‘Collision Assist Unavailable’, and at least 8 other errors that would not go away. Two red lights were indicated on the cluster — one of them looks like a car with a ‘!’ through it, and the other is a wrench. The vehicle is charged every night to 95% using a Level 2 CCS charger directly to the vehicle’s charging port, no adapters. The vehicle had 91% battery remaining when this occurred. About 20 minutes after the incident, while waiting for a tow truck, the vehicle went completely dead and all components were unresponsive. The ignition would not activate, the doors would not open, and the open doors would not properly shut (the electronic catch mechanisms were not catching the door to keep it shut). I could not activate the screen to put it into Emergency Tow mode. The vehicle has 17,999 miles and was purchased brand new in September 2023 with 0 miles.
