Email subject I am reporting a serious safety-related defect involving sudden and complete vehicle shutdown while driving in a 2024 Chevrolet silverado ev rst. Component/system involved: the failure appears related to the 12-volt electrical system and associated vehicle control electronics. When the vehicle detects the 12v battery as dead or critically low, it immediately disables propulsion and control systems. The exact failed component is unknown. The vehicle is available for inspection upon request. Incident description: this failure has occurred twice under similar conditions (ambient temperature approximately 25°f). On November 28, 2024 and again on January 2, 2026, after driving approximately two blocks at low residential speeds, the vehicle abruptly and completely shut down while in motion. In both incidents, the shutdown was immediate, without warning, and accompanied by a loud thud and an extremely abrupt stop. Safety risk: in both incidents, the vehicle became completely immobilized in the roadway. I was unable to steer to the side of the road, restart the vehicle, or shift it into gear to move it out of traffic. This created a significant risk of collision. A similar failure at highway speeds could result in a severe or fatal crash. Warnings or prior symptoms: no warning lamps, messages, alerts, or other symptoms appeared prior to either shutdown. Problem confirmation or reproduction: the issue has occurred twice under cold-weather conditions. Inspections: after the first incident, the 12v battery was inspected and no issues were found. Following the second incident, the vehicle is currently being inspected at a Chevrolet dealership. No police or insurance inspections were performed. This behavior suggests the vehicle lacks a fail-safe or degraded-operation mode for 12v system failure and instead performs an immediate shutdown while in motion, which may represent a serious safety defect warranting investigation.
I believe my def heater has stopped working and my full def tank is now frozen. I’m now stranded in the middle of south dakota in -29 degree weather. My truck will not drive. Or idle for the heater to keep me warm because the def is required for engine to run.
