Rattling Noise In Back Of 2017 Chevy Volt

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.

My 2016 volt has had a metallic rattle in the back right area since it purchased. Dealer keeps saying "can't replicate" although for me it happens on almost every drive, particularly slow speeds.

Had it in the shop a week or two ago and they finally said they could hear it and that it was a "defective rear axel" and that it would need to be replaced if I wanted the rattle to go away. I'm out of warranty so will likely just live with it (~$2800 to fix they say)...

Will try the hatch adjustment people reference above, but this sounds highly metallic and think metal sounding so I don't think it's the hatch. It's frustrating since it's been doing it from the day it drove off the lot as a new car, but no fix from GM.

that’s nuts, can you get a video/ audio of your sound? I still haven’t figured out mine 🤣 rode in the hatch for about 10 miles and I didn’t hear it at all. It just appears so randomly sometimes over the smallest of bumps! I’m still convinced it’s the hatch and I will find it!

my 2018 volt, I had my rear axle replaced under warranty at 13000 miles because of the rattle. I still hear it at 45000 miles, I just got back from dealer. they found something loose in my left rear brake actuator. it will cost me $700 include labor to fix, but the dealer talked to GM and I got it fixed with $200 deductable.

It’s the connectors in the hatch for the rear window defroster.
