Right Rear Bumper/quarter panel coming loose?

My car had a problem with this seam, but in a different way. The lower bumper panel stuck out from the upper body panel, there was not a smooth transition between the two panels. A trip to the Scottsdale Service Center made it better, but it still is not as smooth as on the left side. Nothing seemed to be coming apart, just mis-aligned.

It doesn't take much to bust clips on a bumper since they're made to give way in hopes of avoiding damage to the surrounding sheetmetal. My wife lightly bumped a friend's car once: no visible paint damage, busted bumper clips. I wouldn't be surprised if you got tapped while parked or something at some point. Or maybe they just weren't installed very well. Either way, should be any easy fix. Have Tesla take a look.

That happened to the rear bumper on my Prius. I just pushed it in and it clipped itself back in place. I suspect someone bumped into the bumper somehow and it popped loose.
