The invention provides a vehicle safety early warning method and device, a storage medium and a program product. The method comprises the following steps: determining whether a DC-DC converter of the vehicle is in power supply abnormity or not; under the condition that the DC-DC converter is in the abnormal power supply state, the power supply voltage of a storage battery of the vehicle is obtained; if the power supply voltage is smaller than a preset voltage, reporting a first fault state to a cloud server; the first fault state is used for indicating that the DC-DC converter is in a fault state; the preset voltage is greater than the minimum working voltage of a vehicle control unit of the vehicle. According to the scheme, the fault state of the DC-DC converter is actively reported, vehicle safety early warning is achieved, and the safety of the vehicle in the driving process is improved.
