Update.
Dealer put my car up on their ramp yesterday, and put the bump stop back in. Drove down the road and I heard it come out again

. So there is a problem here.
Called them back this morning, the service manager is going to talk to their technician to see what needs replacing and sort it out

.
Just waiting for the call back now.
Keep y'all posted when I have more info about what they are going to do.
