They can be adjusted but it requires removing the door card and some effort to do it so you can imagine why they would be reluctant to invest that much time into correcting what is something insignificant enough that most people don't even notice.
The handles are only recessed a few mm, but it still bothers me. Looks like I'll have to spend some time on my own trying to make them flush. I was hoping it could just reach the adjustment screw after simply removing the panel, but that doesn't seem to be the case.
you take the inside door panel off and feel around for the large torx screw and turn that either direction to increase or decrease the depth of the handle. If you look on YouTube for how the handle is built or doing a handle repair you can better see the screw I'm referring to but its doable just annoying to do.
