Intermittent Pop Coming From Right Rear Only When Stopped...Anyone else?

[GM-4-LIFE]

Within the last week, I have been getting an intermittent popping sound coming from the right rear of my 2013 Volt, but ONLY when stopped. My wife noticed it too. She got out of the front passenger seat and started walking to the rear of the car and she said it sounded as if she hit the car, but she was a few feet away from the rear of the car when she heard the pop. My son and I heard it and he asked me what that popping sound was.

Anyone else experience this?

it could be the fuel tank purge valve. I hear it occasionally on my 2012.

Why is it only starting now at almost 7K miles?

It never surfaced in the six months I have had it.

Sounds like the rear spoiler is coming undone on the right side.

I will report to dealer at my 7,500 mile tire rotation.

Thanks guys!

People have reported spoiler noises in the past due to loosening - most likely is that if it sounds "up in the rear" rather than low (such as a chassis noise)

I can't really pinpoint the sound location, however it does sound like it is coming from the right rear of the car as if it's from the fuel door area or around that area. It make sense that the rear spoiler is coming loose.

Thanks again!

Strange. Mine makes a clicking sound coming from the left rear tire area after driving. Dunno what it is. *shrug*

I had that clicking sound in the same right rear area, I don't know what it is called, but I thought it was the threaded rubber tipped peg on the hatch, I press on it and it makes that clicking sound. When I brought my Volt in for a CEL, the technician checked it out, but on the invoice he said he found a missing plug. So far I have not heard the clicking sound, so maybe it was a missing plug or he could have just screwed the peg in more so it doesn't click any more.
