About a month ago the rear passenger rubber seal parted company with chrome trim between door and boot lid. It started flapping at speed. This week the driver side trim did the same.

 

I'm having touble visualizing this. Are you describing the chrome trim along the rear window gasket?

 

That's it!

 

....and i'm having trouble picturing what you just said.

 

Go straight to the dealer!!!

 

The person I was asking and I seem to now understand each other. I believe that's what matters here. Sorry to otherwise confuse you.

 

Mine was delivered with this problem. My dealer will replace the entire back right trim piece tomorrow. I'll let you know how that goes.

I thought this was a bad factory install, but after reading your post, now I'm wondering whether the design of the rear side window gasket/trim piece itself isn't faulty.

 

When they replaced the passenger side trim they somehow tweaked the C pillar trim and now it doesn't align with the back and rear windows... anyway its in having that and the drivers side trim fixed today.

My wife thinks it may be the AZ heat that's causing it. I think it happens at speed when there are intense pressures exerted on the part and the rubber chrome interface fails: the two materials appears to be bonded together... not very strongly. I pulled them appart on the drivers side, because I didn't want it to damage the paint work, as it flapped around in the breeze... it didn't take any effort at all.

 

After reading this I checked mine all around the beltline of the car. I can see where the chrome trim seems to "slot" into a trough in the rubber gasket piece.

Mine was popped out a hair along the pice on the rear lip of my hood, but looked good every where else. A little massaging og the rubber seemed to seat the shrome back into place. I'll be keeping an eye on it from now on, of course.

I wonder if using an adhesive between the chrome and the rubber piece would take care of the issue.

 

Okay... it's back from the dealer. They broke a clip for the C pillar alignment and so I have two more trips to get that fixed next week: day one to take it in; and day two to pick it up... I always take in in first thing in the morning and they always let me know about 5:15pm when it's impossible to get to them because of the traffic(min 2hrs round trip)

 

Argh, mine just started doing this today, though on the rear passenger side body (not boot door). I tried massaging it into place, but to no avail. I guess I will have to make a trip to get it reclipped.
