So now after 6 months my mach-e has stopped unlocking the doors on its own. When I walk up to the car the lights still turn on so I know it is seeing me, but when I touch the door nothing happens, the mirrors still stay in and the door does not unlock or open. I have to press the button on the key fob to get it to work. I tried replacing the battery in the fob just for s&g but nothing. I also turned off and on the setting in the computer. Still nothing. Anyone have an idea before it goes to the dealer?
