Hello and welcome to JustAnswer!

The first thing I would suspect given your symptoms is a dead battery. Do you have a way to try a jump start?

Keep in mind the car will be under warranty and a roadside assistance tow to a dealer would be covered, and the rental company should be taking care of this for you as long as you didn't cause the problem.
