I have a 2010 Chrysler mini van with 4000 miles and 4 months old.We have had a problem with the battery going dead.Tuesday morning the battery was dead,that afternoon i jumped the vehicle with our other car and then drove the car around town doing errands.When i would turn the car off it always restarted.It ran a total of about 45 min before i turned it off to see if it would restart. That night i put the car in the garage,checked to make sure all lites were off and pulled the key.I watched to make sure all lites went off. The nexted morning it was dead again,i jumped again and took it to the dealer.after 2 hours they gave me a rental car.That afternoon late i went back to the dealer and i was told they did get it to fail again but,they were still checking it.I told them i would be out of town on thursday they said that was fine.Thursday morning they called and said they had no problem with the vehicle and we must have left something on.They would keep checking car all day and call me Friday.This was after they told me on Wednesday that they got it to fail.Any ideas.Thanks BR

 

Sounds like something like an intake heater etc is being left on, I have had it on my 1999 Voyager, I know what is causing it, but on mine, it is sporadic and impossible to track which item is sticking on.

 

US vans dont have air intake heaters only CDIs

take it back to them let them have it until fixed its under warranty there is not real way for some one online to tell u what is making the battery draw that is something that needs to be looked at first hand.
