Sunroof rattle when closed.

[Reeko]

I have had my 2010 SS for 2 years.
In the last few months I have noticed 2 things about the sunroof.

1)When I close the door while inside, I hear a loud rattle or mechanical noise from the closed sunroof. I nottice that it seems to pop up a little from the air pressure then lands making a noise.

2)When I drive and hit some bumpy roads at speed, or when the wind makes a pulsing pressure wave (when only one window open) the sunroof rattles loudly. I can see it kind of bouncing.

Is there nothing that hold the roof down? I notice I can push it up a small amount?

I saw something about a possible TSB but see no details about it. Are these not made public?

Any help?

Check to see if any loose screws. I was worried about my sunroof rattling too but realized that my sunroof wasn't completely opened or closed and when
I hit bumps in the road it would rattle. But my case is different then yours.

warranty work from dealership sounds like. i wouldnt try to trouble shoot any of that so they can decline working on it

I do apologize for the dissatisfaction you are experiencing with your vehicle. Have you been able to bring it to the dealership for a proper diagnosis? Also, this may be something that is covered under warranty as long as you are within the given parameters of 3-years/36,000 miles.

I have not taken it in yet.
Plan to next week. I am at 24K miles so still OK.

So,
Taking it in next week.

Short video of the noise that happens if I hit 80MPH with only one window open. Anyone else have this problem?

It only started a few months ago.

Had a similiar situations w/ my wife's equinox. They fixed it under warranty.... they said they put shims in place for a tighter fit. All is fine now!
