When I hit the trunk release it only unlocks the trunk, I have to open it manually by hand. I looked and it has the same tension rod set up my SHO did. When I hit the trunk release in the SHO it would pop right open all the way. Try your trunk release and let me know what happens! Also protect your carpets the rods on mine were so heavily greased grease was ready to drop into my trunk. Check yours and save your trunk carpets.
