I will call them tomorrow. It does need to get addressed though as it was a complete surprise. I’d live with the occasional rare glitch of this if the car would have given a warning or some status alert that the vehicle no longer had brake hold, but there was zero alert, caught by surprise when it rolled backwards, and then I checked the menu and it was grayed out, couldn’t switch back to hold. Where I live in Providence RI is actually called College Hill, and parts are just like San Francisco! Very strong chance of rolling backwards without brake hold!
