Just need to loosen the bolts from inside the trunk. Raise the catch plate a little and test it. Make sure it's high enough so that it isn't too tight, but make sure the trunk lid isn't too loose, or it will rattle.
holy crap this is annoying... everytime someone asks "how big is the trunk" Im actually excited to show em (roadsters and hatchbacks dont have but like 3 cuft lol). Then I remember... o ya the thing wont open 100:101 times. I gotta get it fixed, thanks for the link!
also is there a way to test it for rattles without driving? So you dont have to adjust... drive... adjust ... drive... and so forth? Thanks
ya its really easy to fix this (as I just did in 5 minutes). Grab a 12mm socket, undo the 2 12mm bolts slightly, slide the plate up a little, tighten, then to test if its done correctly, push on the trunk and if it has any "play room" and you can feel movement, move the plate down some til it sticks firmly. Thank goodness for this... I Was goin to go crazy not being able to open my trunk.
I too suffer from the trunk release problem. I've had my STI for about 2 weeks now. Don't fret though it's not a big deal, I use to have a WRX and it had the same problem. Actually a body shop fixed it for free while I was having badges taken off, so I plan to take my STi to the same place to correct the problem. Take it to a body shop or your local dealer to fix it It's just another little Subaru kink, like the drivers side window squeaking, etc..
