The glove box handle on my '08 came off in my hands the first year I had the car.
We never had any problems with the '06 glove box handle.
Btw, the '08 handle is gray and the '06 handle was cashmere.
In my case, I found a small open end wrench that I could pull the latch with and that opened the glove box until I could get the handle replaced.
I was lucky there also as I was loading the Vette for a trip to the NCM. When I got there, I checked with Adam Boca of the NCM and he gave me a number of a guy at the plant - memory fails right now. I called the guy and he had another man from the plant met me at the tourist entrance. When I showed him the pieces, he went back inside the plant and got the parts I needed and replaced them just outside the tunnel. Have not had a problem since.
My guess is that some of the '08 handles were over hardened in production and therefore brittle. Lucky for me, the NCM and Plant came to my assistance and fixed it on the spot there.
