2007 Hyundai Entourage won't start. Battery is fine. i assume it is a computer problem. What is the fix?

We're having the same problem. they replaced the anti theft junction box (there is a service bulletin for this) but it will cost you about $470.00 and there is a computer problem as well. it took 3 months for them to find this out. the computer is on order for ours..$1500.00they want nothing to do with it. you are right, the battery is fine but ours would be drained dead in a matter of hours of shutting off the car. don't give up on the reasons they give you...the vehicle has serious issues. im selling or trading ours as soon as its fixed.
