The front underside belly protection pan - all plastic - has come loose and is hanging down. I haven't hit anything, nor has my wife. We did just get the car back a couple months ago from a new engine install, which had the whole front underside removed. When they placed the front underside protective pans back on, were they supposed to use thread lock or similar? It looks as though the nust have just come off the frame mounted studs. I'm planning on taking it in to the shop for them to lift and look at it. I'll have to zip-tie it back up for the drive up there - should look great that way.
