Movie Bumblebee problem solved, it is broken, WARNING to all!

When trying to transform Bumblebee back to alt mode, the front end won't stay connected. It is as if there is a spring loaded part that keeps popping it open. Am I doing something wrong?
I can't believe I transformed my MP Megatron back and forth without looking at the instructions the first few times yet I am having problems with this. I'm thinking there is a defect but am curious if others have had this problem too.
UPDATE
I found the problem. There is a thin and fragile plastic tab holding the front end together. When you push the button on the hood, it releases the front end. It also locks the front end into place in alt mode. If this little piece breaks you are left with a car that will never fit together again.
I have noticed that the movie line deluxes I have seemed to be made a a lower grade of plastic compared to previous lines. It feels like the same quality plastic used on the legends of cybertron mini figures. Thin and brittle.
This is too bad, really. I like the figure but I only transformed it once and it breaks! Be careful with yours. Maybe I just got a defective one, who knows. I will be exchanging it for a non-defective one regardless. That's the one nice thing about buying from WalMart.
