2017 Chevrolet Silverado 1500 Electrical System

DRIVERS DOOR COULD NOT BE OPENED FROM INSIDE THE VEHICLE. HANDLE MOVED BUT DOOR MECHANISM WOULD NOT ENGAGE. HAD TO LOWER DRIVERS WINDOW AND USE EXTERIOR DOOR HANDLE TO OPEN THE DOOR. AFTER TURNING VEHICLE OFF AND RESTARTING THE ENGINE THE DRIVERS DOOR INSIDE DOOR HANDLE MECHANISM WORKED AGAIN. I'M CONCERNED ABOUT BEING ABLE TO EXIT THE VEHICLE QUICKLY IN AN EMERGENCY OR IF POWER WAS DISRUPTED TO THE VEHICLE AND WAS UNABLE TO LOWER THE WINDOW. VEHICLE WAS STOPPED IN A SNOW STORM (BLIZZARD) ON A BACK COUNTRY ROAD AT THE TIME OF INCIDENT
