My gen3 won’t start. Any ideas?

My 2011 isn’t starting recently. I get in, put my foot on the brake, make sure the start button light is green, not amber, and press it, like I have done for the past year. However, lately it doesn’t start. It puts it into the on position without running, so all the lights are on but the car isn’t running. Sometimes I can keep my foot on the brake and keep trying the green start button and it will start in a few tries, but sometimes it just won’t start. I have no error messages, and my key fob battery is brand new. Any thoughts?

Side note: it has recently gotten significantly colder about the same time this issue started, not sure if that helps.
