About 3 weeks ago, my nephew was playing in my Jeep (he's obsessed with it) It was parked in the driveway after we drove home for about 10 minutes. Went to start it up to head home and it did not start. All dash lights came on and nothing. Turned key back to off position, tried to start again, and while it was a hard start, it started up.

Fast-forward to yesterday. Went to get gas, turned Jeep off to fill up the tank. Once tank was full went to start and nothing. Waited a few seconds, turned key back to off, tried to start and again, a hard start, but it started up.

Points of information:

* Recently (about a month ago) I replaced the gas cap because I got the PO456 code....replaced gas cap and it fixed the issue
* I have never replaced the battery on the Jeep, I've owned it (bought it new) since November 2011, have 66,120 miles on it.
* When I start the car, the clock displays as 12:00 but then after a few seconds displays the correct time
* I've experienced issues randomly (less than 1/2 a dozen times) with the radio, not being able to turn it off, change the volume or the station until I restart the Jeep
* I do feel the starts have been a bit harder as of late (maybe 1/2 to a second longer than usual), I actually began to notice this, this past winter but attributed it to the really cold winter we had in NJ and then it became the norm.
* This major issue of it not starting at all has only cropped up after trying to start it after it's been turned off for a short period of time. Both of the times it wouldn't start were a result of trying to start it within 3-10 minutes of it being turned off. However, longer pause times, ie ran into the grocery store for 1/2 hour, it seems to have a hard start. Starting in the morning after sitting over night or after work after sitting for 8+ hours don't seem to be nearly as hard of a start.

Any insight is appreciated. I'm hoping it could just be the battery, but if that's not the case I don't want to get ripped off at the mechanic.

Thanks in advance!

Any shop will load test a battery for free usually... or you can 'load test' it yourself. Start it, let it run for only a few seconds... turn it off... do this 5 times. If it gets slower and slower cranking, you have a battery problem.

With the age of your battery... yeah... start there. You can clean the posts and tighten them just to be sure... but I wouldn't waste much time on a 7 year old battery.... 5 years of life is pretty good for the average lead battery.
