I am not sure. I would assume it would need to assembled by a factory tech to be covered under warranty. I would just get on the phone with them asap and get a new unit shipped to be safe! This type of issue is not supposed to happen with the quality controls in place.
It could have also had an issue during assembly that needed to be repaired and some how made it through. Don't waste time, they will send you a new one and you know there are no issues!
