When I turn the key in the ignition there is no power coming to the vehicle.

What is your question?

A couple weeks ago the same thing happened and when I popped the hood, the power came back on, I started the car and carried on. Today my car was dead (the battery is brand new, and given what happened last time I’m confident it’s not dead) and after popping the hood and making sure the battery cables were secure it still didn’t power on.

How long has your 2003 Saturn Vue had this problem?
