Hi all,

I'm literally going to snap! I took out a brand new 2023 Traverse and I love the drive, the space, and everything about it. However, after owning the car for around one week, I noticed a front-end rattling noise. I immediately contacted my dealership, but they are quite far from me, so I decided to do some research first.

After doing a lot of research, I found that this is a known issue for the Traverse. I took it to a nearby CERTIFIED Chevy service location and they told me it was normal. However, after I convinced them that it was not normal, they told me the loud rattling noise comes from the Purge valve and they would replace it. But, if it didn't fix the issue, I was out of luck.

The noise is still there, and it's driving me nuts! The car is never quiet! I did see some older YouTube videos of people replacing the Purge valve, and the rattle stopped, but none of them were from the newer model. So, it might be that the rattling sound is normal for old purge valves.

Now, I know three people who have the new Traverse, and all of them have the same issue. I mean, where are we? It's 2023, and we have brand new Chevys and every second Traverse owner has this issue, and there's no resolution!

Whoever can help me with any information that will lead to a fix, I'll quick-pay you $100!
That's where we are in 2023 with American car manufacturers..."

You're not alone:

A couple of cents each for a couple of rubber donuts and Chevy won't install them at the factory. WOW.

I concur - if you're in warranty, take the TSB to the dealer and say you want it installed.

Otherwise - I bet you could use a piece of foam pipe insulation from Lowes/Home Depot and do it yourself. Maybe run the foam the length of the pipe. rather than 2 donuts. You can get the pipe insulation in different pipe diameter sizes (i.e., 1/2", 3/4", etc). Check the size of the "pipe' and buy accordingly. And I'll bet you can get piece of insulation for less than GM will sell you a couple of "dampeners."

I'm guessing that it MAY be more of a "sound deadener" than a "damper," but who knows?

OR - if you're leery of the dealer, try the pipe insulation yourself first. If it doesn't do the job, take it to the dealer.
They appear to be a much denser foam than pipe insulation.

You can get the real thing for $7.30 each here:

Hmmm, ordered the parts....
I think they got lost. Were to be delivered yesterday. Theyve been in Wilcox, Az for 3 days now.

My 2 pieces, and the pressurized coolant bottle for my 13 equinox. I found it has a crack, allowing drops of coolant.
If you lived in Rwanda, you might have had your parts in a hour or so!
