    Default Steering Wheel Controls INOP

    Has anyone had problems with their steering wheel controls going out. Mine will work for a while and then stop. Shut everything down and start again and it works...for a while. Dealer has already replaced the box under the dash and has not fixed the problem. So just wondering if its mine or other guys having same issue. 2022 450SL

    Happens when you don’t let both screens fully boot up before starting engine.
