IIRC, the soft close was only offered on '08 and '09. Maybe '10. Not sure why they did away with it. I also like it and knock knock knock...haven't had a bit of trouble with it.
On my 05, I find the trick is to just let the hatch do the work, and not provide and 'force' to help it close. Honestly, after I got used to it, its not a big deal anymore.
Right, only on '08 and '09. My cinch motor broke a couple years back and it was an easy replacement.
I love being able to lay the hatch down softly and having the motor pull it in gently the rest of the way. The hardest part is catching other people before they slam it with the fury of Thor [hand of forehead].
