Unfortunately my spoiler is tight; no noise when I try moving it. My sound appears to come from the rear suspension.

Thanks for the update. I have a feeling the more I think about it and listen that the spoiler isn't the cause either. Going to have it fixed anyway to eliminate it.

I just had a clunk in the rear, as described in this thread, fixed. I have 8,000 miles on my 2012. They replaced the right rear shock. The sound is gone.

Good Morning Scott,

Glad to hear your dealer was able to resolve the sound concern with your Volt. Thank you for you sharing!

I had that shock replaced too. Seemed to be ok for a day or two then came back. Seems to be getting louder. Probably just going to wait until it fails completely so the dealer can't say "couldn't duplicate concern".

Was ther ever a solid answer to the noise in the rear

I am a little late to this discussion, but need to find out if there is a safety issue.
My 2012 started making a rattling noise going on rough roads last year at just about 36,000 miles. I didn't think much of it expecting it to be a loose muffler hanger or something. The car was pretty much in my garage for the last year while we traveled in our camper. So now I am ready to head east in the volt, and asked my local mechanic to look at the rattle (nearest Chevy dealer is a couple of hours drive away). He is leaning toward the wheel bearing idea. Not something that I want an average mechanic replacing on a whim, not to mention a hugely expensive part.

Thanks for any help on this.

Mine turned out to be a bad shock absorber from new. The dealer replaced it under warranty. I see I had written that up earlier. Sorry for the repeat.

I had a clunk in the rear, as described in this thread, fixed. I have 35,000 km on my 2012. They replaced the right rear shock. The sound is gone.

But now, it seems that a similar sound is coming from the left front. When to the dealer but we were not able to reproduce the sound.

Anyone had a issue with a front shock?

After they replaced my right rear clunk, about a year later, the clunk is coming from the left rear. I haven't gone in to ask them to replace it yet.

Hello Oldertech,

I can understand how bummed you must be to hear that clunking noise on the other side of your vehicle now. If you're interested in bringing it into the dealership, please send me a private message. I would be happy to create a case for you and notify your Volt Advisor. They serve as a fantastic resource and want to ensure the whole dealership process is up to your standards.

[PriusToVolt]

[El Dobro]

They're changing the whole rear suspension?

 

[NYRob]

You guys got to get those bodies out of the trunk!
...Or is that just a NY/NJ thing?

 

[El Dobro]

The Trunk Monkey is probably loose.

Here is my add to the "small clunk" in rear end that I can duplicate without fail. It's been diagnosed by GM, they say it's some "trailing arm like" item on the rear axle. The solution is to replace the entire rear end, and included some one-time use bolts. They gave me the car back and I am apparently waiting for these "rare" parts. They also claim it's never been seen before. You can easily duplicate the error by turning around a corner or in steady circles. They of course ruled out EVERY item from hatch, body work, struts, etc. The reason I am posting now is that the wear at 16K is now advancing quickly and the noise is louder. No ETA on parts, dealer won't keep car, I am angry after one year of a lease that has had my car in for 2 recalls, one rear camera/interior light failure and now this. It's both distressing and unfortunate but having found this list wanted to post that it's not a mystery it's a problem they know about.

Did this get resolved? I have the same problem on my 15. The dealer I bought from has the most pathetic service dept I've been to with any car. They are apparently deaf.

Interesting. I started getting a "scratching" noise from right rear wheel area about 6 months ago, at 5000-6000 miles, when I turned right. Had the dealer look at it then, they couldn't repro, even though it seemed pretty consistent to me. Had the car in just yesterday (for first oil change), 8500 miles, and repeated my complaint. This time they confirmed the noise, and want the car back for another day to investigate further. And I've recently started to notice the same noise sometimes from the left rear on doing left turns. I've been suspecting strut or loose wheel bearing.

A Solution!

Rather than start a new thread, I'll put it here since there are good discussions and descriptions previously. Yeah, I've been having strange noises from the rear, coming and going. In the process of installing a rear sway bar, I found a major part of at least my problem. To do it, the lower shock bolts are removed and the trailing arms of the suspension rotated down. This makes the springs easy to remove. Besides being squeezed between the body and trailing arm, there is a spring locator "cup" on top and bottom (see first picture). The spring top and bottom slips over the cups to keep them in place. Between the cup / mounting surface and the spring is a rubber pad to prevent metal-to-metal contact.

When I pulled the springs out, on the top side of one, the end of the coil had punched through the rubber (see second picture). Based on the shiny metal, a sharp edge of the spring had been rubbing directly on the locator "cup". I rounded off the offending edge using a Dremel with a stone, then replaced the following parts:

1 x Insulator, Part #90538496 @ $3.91
2 x Shock Bolts, Part #11610587 @ $1.82

One irritation gone!

BTW, it's a pretty easy DIY job for an experienced DIYer. No spring compressor needed. Though do replace the shock mounting bolts with new; they are torque-to-yield which means that once loosened, they're trash.
