Hazard flash when shut off?

Hi All,

This week, my truck started doing something unusual. Sometimes when the engine shuts off (has happened with both the auto start/stop and when I shut it off after parking) there is a quick flash of the hazard lights. Just one quick flash and it doesn't do it every time. It has happened multiple times this week. Just wondering if anyone has experienced this, or if it might be an indication of something failing.

Thanks!
