Anyone fixed a C pillar cover rattle?

[tvad]

We have a rattling passenger side C pillar cover. When parked, I can tap on it and it clacks/rattles. I slid some sound deadening foam between the top of the cover and the rear glass to keep it more securely in place, but it hasn't made significant improvement. I have seen a video showing how to remove the cover, but there's not much behind it. I'm thinking it might be a broken/loose clip or two.

Anyone have any first hand experience with this particular rattle?

I scheduled an appointment and they fixed them. They are aware of the issue. There was no charge.
