billm1146 The photo POV is looking into the trunk on the passenger side. Driver's side is basically a mirror image.

billm1146 UPDATE:


On our cars there is a plastic "ice cooler" housing the top folds into. It is viewable with the trunk lid open. This is the same housing that can be retracted from the trunk up and into the tonneau area when the top is up to give more room in the trunk.


On each side of the housing is a metal frame that supports it. There are two round metal arms, one on each side, that slide over a short axle and are secured by a flange. (See the picture below) The flange tends to work loose and these arms can work their way off the axle and dangle/rattle. If the arms are simply put back in place, secured with the flange and the flange is secured with some light duty Loctite that may quiet your rattle.


Note that when the flange works loose, it will fall into your trunk down into the carpet. With a good flashlight, you should be able to find it.

In the pic below, you can see the passenger side arm clearly (aluminum color) with the problematic flange attached at the end of the axle. If the flange works loose, the arm vibrates off over time, comes off the axle and dangles loose in the trunk.


Well, the board will not let me add my Flickr URL so I can post the picture. Any suggestions, anyone, on how to post this photo?

Here is a link to the photo, so just click on it and the photo should show make this clear:

kadeytoby My driver side is rattling in the back by the window when I hit a bump. Lubricated a lot of parts and still there. If I could get a picture also. [email protected]

Rattle

I would be interested in a photo of the parts described (fork and roller) as well.
[email protected]. The rattle is really annoying. Thank you!!

top rattle

Maybe the poster with the solution could post a photo. I would also be interested in seeing the parts to be lubed.

Frank the Tank Can someone email me or text me a picture of the "2 prong fork bracket" mentioned in the Buick Cascada convertible roof noise mentioned in Dadio's article above. I have sprayed all of the brackets with no luck in stopping the noise. Email me a photo of this bracket that I need to spray at [email protected] or text me at 702-768-3703.

DIY Solution

I had the same annoying rattle shortly after buying my 2017 Cascada. I ended up sitting in the back while my wife drove me around until I found the noise. With the Top halfway up you can see a 2 prong fork bracket. Those prongs end up around a little roller once the top is up. I started out with a spray lubricant (WD-40) on the roller which completely eliminated the noise. A simple spray seams to last a couple of months then needs to be reapplied. I got tired of that and applied a paste style lubricant to the roller and have not had any noise since (about 4 months now).

Defective Valve Cover Causes Whistling

I noticed an audible whistling noise (mechanical not rush of air) several weeks ago. It became louder and when the engine was turned off it whistled at you for about 5 seconds. My dealer , Norman Gale Buick/GMC has been great and believes the problem is a defective valve cover. The trouble is that there are none to be had. The part has been re-engineered and is being produced in China with a ship date in late August. Probably won't arrive in the US until weeks later. It may be that the Cascada sits at the dealer for what could be 6 weeks or more. I was handed the keys to a new GMC Acadia so I've not really been inconvenienced -just puzzled and annoyed at why GM hasn't done a recall. Heads up out there. I can't be the only one. I can't stress enough now accommodating my dealer has been.
