If the recall is for something nonessential, I usually just ignore it. I had a GM product for years that was covered under the infamous ignition switch recall. Never took it in just to avoid the inevitable BS and the sad and disparate attempts at up-selling that usually occur.
Dad had an '06 DTS, he had the recall done. It was so cheap / cheesy he wished he'd never done it. It was cheaper / chessier than Ford's recall fix for the infamous burning trucks recall back in the late '90's.
You did good ignoring that one.
