So took a little drive today and noticed something. My auto start/stop was not working. Now don’t get me wrong, I hate this feature and have it disabled 99% of the time. Hard for me to believe something around my spare tire could affect the start/stop feature? Anybody have any thoughts?

Not sure if this is the case. But if you had not driven it in a while, short trips that don't give the vehicle time to charge itself, or for some other reason the charge of the battery is a little lower than usual, the battery management system will temporarily disable the auto stop/start until it thinks is charged enough. So, there may be nothing wrong. Go drive it for an hour and see if it re-enables itself.
