    So this happened a few hours ago.
    While driving, these lights came on on the dashboard

    Ignore the seatbelt light... I was stopped and parked at the time the pic was taken lol.
    When those lights came on, I noted that when I pressed on the brake pedal, there was ZERO response until I dipped lower here the friction brakes would kick in. The CHG bar was also not increasing when I touched the pedal.

    I have no check engine light on, so my head unit won't scan for anything...

    I can also hear the brake boost doing some very short pulses.
    I have a video with it doing that but I can't seem to upload it here.

    Any suggestions :-(

    Suggestion to count errors to determine the reasons for failure. Best with a scanner specifically designed for this purpose.

    I have an OBD-II wifi scanner at home.
    Was planning to check on it later to see if I get anything.

    Sigh

    Still love this car though

    Anything constantly plugged into the OBD port?
