    I think there is nothing wrong. When stationary with the brake pressed, there is power applied to the MG1. You can notice this because there is a slight movement when you go from P to D and when you release the brake pedal the car immediately wants to creep forward.

    I see that if I'm not pressing down enough on the brakes. Car is still so it's enough brake pressure just not enough to stop the current. Would think there's some adjustment or setting. I have a gen 2.

    if the switch was not working, you wouldn't be able to make the car ready. do the brake lights operate?

    That does not look normal at all. And as @bisco said, if the brake switch failed to work you couldn't make the car READY.

    Your ABS and Slip Indicator lights are illuminated, which are issues that could relate to your problem. The Slip Indicator could just be because you mashed the brake pedal down when you stopped, but the ABS light indicates another problem. Get them checked out. Also, get that windshield replaced!

    Yeah. Good catch indeed, @RRxing. I was so focused on the energy flow, I missed everything else.

    Also, your Brake light is on, which should only display if the parking brake is on. Was your parking brake on when you filmed the video? If not, it's another clue that something ain't right.

    And get that windshield fixed... :whistle:

    I’m having this same issue with my 2016 but it only has energy flowing while I’m stopped on a hill. Not sure why it’s doing it as it’s not normal and no fault codes were found.
