After driving the truck around for roughly 10 minutes, zombies appear frozen and you can not exit the truck or turn the engine off or interact with anything.

You can still drive the truck around but that is it.

After exiting the game and relogging in, the character appears on top of the truck but you are still unable to interact with things like doors or pick up items, carry out player actions.

A server restart does not fix the issue neither does restarting the xbox.
