I have a vert and would occassionally get this issue which became more of a problem over time. I took the trunk apart thinking there was a latching issue; but manually testing the latch once I'd gotten it out, everything worked just fine.
Further searching led me to check the rubber stops on the lid. They screw into the lid. In my case, I had to back them out a bit (turning them counter-clockwise); but you can try either direction to see if it helps.
I also bought, but haven't installed, an upgraded pair of stops that are now available which are spring loaded.
