Owned the vehicle for almost 4 months. Just noticed that there are 2x random adhesive foam on one of the rear door panels and wondering if anybody knows what that is?

Checked all four doors and I only see it on the rear right panel as shown below. Is it something normal that the mfg adds on for the transit and the dealer just forgot to remove it or it's something else (misassembled or anything else)?

I'm planning to remove it as it seems weird but wanted to check if someone had the same issue.

Thanks in advance,

 

Looks like stuck, random pieces during assembly.
Hard not to miss against the white paint...
Hopefully they come off easy.

 

Strange that a company with "luxury" aspirations would allow something like this to make it to the final customer on delivery.

On my TLX, I've got rattling in my driver-side quarter panel that I believe is insulation-related. It was brought to the dealer to fix but they couldn't. Feels like the glass could shatter with a really violent jolt.
