Hi everyone, I have a 2017 chevy volt LT. Every time I ride, especially when I am going over bumps and bumpy roads, there is this rattling noise like an aluminum can bouncing around against metal. I think its something loose inside the rear trim assembly of the cargo lift/hatchback because when I shake or push back and forth the lift, the same sound occurs. I don't think its anything serious or something that immediately needs to be addressed but its really annoying to drive to. I tried to remove the rear trim assembly myself but could only open it partially as I was afraid any more force would break it. Any help would be awesome.
I also have a 2017 volt that experienced the same problem. Mine turned out to be inside the hatch itself. The dealer fixed it under warranty. I think they ended up replacing the glass. Hope this helps. It drove me crazy.
