The trunk is supposed to open by push button assist. It doesn't usually work...

What is your question?

I don't know if it matters but my car is equipped with keyless-go. Anyways, I think it is common on this car or any S-Class, but there are two buttons underneath the lip on the back of the trunk/above the license plate. The button that opens the trunk doesn't usually work. I will push it once and it will A) open fully B)open partially and I will have to push the button once more or C)it will open 1cm, push it again and it will open to 1in, push it a third time and it will open fully or D)it will open 1cm, push it again and it opens to 1in, push it again it opens 2in, push it a fourth time and it opens all the way. I have a problem with all of the buttons on my door handles as far as they don't work correctly either. Is this just an overall issue with my keyless-go system or is it something else?
