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!

Here is a pic of the factory repair. My source for the TSB's is the NHTSA site in the below link. Plug in your make ,model , and year of vehicle and click on the manufactures communication tab View attachment 11871
Would there be a different bulletin # for model years other than 2020-2021?
Based on the pic online doing a search on the sleeve part #...
It is just a foam sleeve.
Im thinking buy foam sleeve yourself and zip tie it in place.

Xltbest, can you post pic of the finished work?

You know, sometimes you as the owner can be gentle and kind to your vehicle vs the lowest guy on the totem pole doing this install.

Like when they did the wiper recall on my equinox. Wipers were way off... actually wiped off the glass on the drivers side.
I had to pull and reseat the arms in the proper location.... vs taking it back and waiting.

@xltbest thanks so much for the picture. I just bought these dampeners from GM and il do it myself. Looks too easy to do!
What is that actually material the dampers are made from? I rubber vacuum hose, but the noise is still there.
