Sorry you are having problems. The battery should have been easy to diagnose, surely the service center has a battery load tester. Sounds more like a charging issue if it stopped while driving. Was there any warning indicators lit up on the dash before it stopped? A battery has a reserve capacity meaning it can run the car for some amount of time if the alternator is not charging. The time is 80 minutes with a brand new Venue battery. Alternator charging the battery is controlled by the engine computer software. Hopefully they are right and the software update fixed the issue.
