One day the spring from the trunk jumped and since that day the trunk falls unless you hold it.

Trunk will not stay open. My battery went out and couldn't open the trunk with the key or from the inside and the battery is in the trunk.

The problem is a serious safety hazzard but Mercedes has a repair kit available to fix the broken spring hook on the trunk hinge. Sorry I do not have the part number handy. It was about $60. One kit contains two brackets and four bolts and nuts, the kit will repair both hinges. The repair is fairly simple and can be done without removing the trunk lid or hinges. Just remove the trunk linings to gain access to the hinges and attach the new brackets with the included fasteners. One of the bolt holes in the hinge needed to be enlarged slightly with a drill bit. Attach the new parts and reattach the spring and test. Voila!
Trunk was opened with remote and when I went to open it fully ,it felt very heavy,unaware there was a problem,it came down with force and hit me on the head bruising the back of my head.When I investigated, I found a broken bracket and unattacked springs on both sides. I'm furious!!!
Is there a recall on this dangerous malfunction?

Both trunk springs broke. The repairs are estimated by MB at 3-4 hours (~$500). The springs are only few $.
