Since there is a gazillion pages in this thread, I didn't search every page, but I found something on my car that might be part of the issue on some of your cars. I had my springs replaced which helped drastically, but recently I noticed one of the hatch bumpers (in picture) was missing. I just replaced the missing one tonight and it helps the hatch pop loose even more quickly.
I may be the only one with this issue, but just in case...
