If the question you're trying to ask is whether the red reflective sections adjacent to the tail lights at the sides of the lower glass light up, the answer is no. They are just reflectors (which will appear lit up if someone takes a photo with flash...)
There is, of course, a center high mounted stop light on the underside of the spoiler which should light up with the brake lights.
I'm not sure how you fight a mistaken fix it ticket like this - maybe talk to a Chevy dealer or Volt advisor and get a signed statement certifying that those reflectors aren't intended to light up?
Edit: well, they don't light up unless you're this guy.

(Sorry for the delay in replying. My first response was vaporized because I had my sonic screwdriver in the wrong mode. Maybe I should have written it on paper... pulp... wood... nevermind)
Anyhow, yes, the photo you showed was similar to what he showed me on his phone.
The lights in corners do light up as does the CHMSL but nothing on the hatch... even though it looks like it should. I found that they lit up on the first concept car, too.
Good idea about contacting a Volt advisor assuming they are available to 2nd owners this late in the game. I just found the direct number for them, too.
I'll also see if I can my dealer to print the page of parts for the hatch to show that there are no lights in there.
The other piece of evidence is to take a photo of my car with the brake lights on and print screen shots of video reviews of 1st generation Volt. There is a Volt for sale about 140 miles away that I might go and take a picture of, as well.
The goal is to do this in one trip because where I have to go is in another state and I don't trust the mail-in option.
Thanks for your reply and, again, I'm sorry for the delay.
Cheerios!
