2007 jeep commander overland problems starting sometimes

2007 Jeep Commander overland edition has starting issues. Out of the blue it seems to not want to start sometimes. It's under warranty and the Jeep dealer couldn't find anything wrong with it. Were not sure if this has anything to do with it, but we left some of the windows down, it didn't rain , but lots of condensation was on the windows inside and out. Jeep started, but later in the day would not start. We didn't think anything about the windows being down and the condensation maybe having something to do with it until yesterday. We left down some of the windows, there was lots of condensation on the windows and it started, but later in the day it wouldn't start again. We would really appreciate any help or advise. Thanks so much.

Does it turn over good when it won't start?
