WTF.....

[Grape Ape]

Came out to got to work Monday morning and my new H3 (3 weeks, 600 miles) would not start. I had dash lights, but the engine would not turn over. No clicking....nothing. I jump started it with my wifes vehicle and took it to the dealer. They had it over night and called me to pick it up. They said they hooked it up to the computer and could find nothing wrong. They said the battery was a little low so they put it on the charger. No real explanation as to what happened. So, I am just supposed to hope it doesnt happen again?
Anyone have this happen before?
