I was reading the USA forum gm-volt.com and noticed this post:
Thought you would like to knowJust got a White Diamond Tricoat Volt last week, loving it, but I just noticed something last night that seems rather dangerous. I had my son in a child seat in the right rear seat while I opened the hatch to put something in the back. I see him reach his arms over his head and touch the top part of the hatch opening. I had to strongly tell him to never put his hand up there. Seems like this could result in a lot of injured fingers of toddlers. Anyone else notice this? I did a brief search and didn't come up with anything.
