Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, responsive to receiving a request for sanitization of a vehicle interior, operating a heating, ventilation, and air-conditioning (HVAC) system to heat the vehicle interior above an upper threshold temperature for a threshold duration. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes.
