2017 MS 75D 48k miles. Mobile tech is outside replacing for the 4th time now (both lights are affected). Take note, they most lower the front bumper to replace the headlights. After the third time they replaced these, the tech did not properly secure the "valence," as Tesla calls it, under the car. I call this a skid plate, but it's essentially the big black piece of plastic that attaches to the front bumper and should be flush with the groove in the bumper. There are notches and slots and plastic screws that help the valence stay put. If they don't reattach it properly, it will detach while driving at high speed and drag the ground, which happened to me. As you might expect, it got damaged while dragging. Tesla had to replace that for me and they did not agree with me that it was caused by their failure to re-attach it. End result was a $500 charge for parts and labor.
