HELP! I'M LOSING MY MIND....

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..."

Print the PDF in post #5 and bring it with you to the service dept. Your in warranty, let them fix it and call the Customers Assistance number in your manual to let them know that you know more about your vehicle than your dealer.

But dampener needs to be a genuine part or any is good? I'd rather go to my local mechanic that he should do it since my dealship's service sucks

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.

Exactly. I feel that sometimes the mechanic does a non clean and messy job. If I can do it I prefer that.

@xltbest is it possible that the dampener don't seal the entire pipe all around? I just got mine in the mail put it on and there's a gap between one side and the other. Hope I'm clear enough and it would be a huge help if you can clarify this.

I bought three pieces and installed them, and the noise has decreased by 97%!
I plan to install a fourth piece to cover the entire pipe, and I'm confident that will take care of everything.
I want to express a huge thank you to everyone who contributed to this post. I'm glad I started this discussion, and I hope this solution brings relief to as many people as possible, just as it has for me!
