Sorry Matt, my car made a metal on metal type of sound. Yours sound more like a duller clunk. Are you able to replicate that sound every time? If so, I would bring it to your dealer asap and show them that video as well. Have the service writer sit in the passenger seat while you demonstrate the noise. I went through two service writers before having this issue rectified by demonstrating the noise in front of him. I work at a motorcycle dealer so I understand that if the problem is not present or cannot be replicated, we cannot remedy the issue. Intermittent problems are most frustrating to deal with. Hopefully it's nothing serious but keep us up to date.
