The front grill fell off the vehicle while driving. I was actually in the process of bringing it to a service center to have the hood bracket reattached. I had also fell off and is currently subject of a recall (the federal safety agency campaign number 24v826000). I was able to retrieve the grill and on inspecting the brackets that hold the grill on, there was no adherent epoxy suggesting it failed to bond correctly (which was also the issue with the hood brackets).
