UPDATE: After getting over my shock at the idiotic response from my dealership I just went online and found others who've had the same problem. Then I went to YouTube and watched some dudes take apart the door panel and trim so I could see what the parts looked like. Next, checking a Ford parts website I found that these clips, W714972-S300Body D-Pillar Trim Panel Clip, which cost $1.97 for four of them are what's needed to secure that handle in place. On Amazon I bought these aftermarkets, 30 for $9.99 and they delivered them in 24 hours. It took precisely 5 seconds to install it and now the handle is secure. I'm tempted to take a couple of them to that service advisor and educate him so maybe he could actually help another Explorer owner in the future instead of blowing them off with some B.S.
