Last Month, My 2017 Jeep wrangler did not start I tried to Jump start it and it worked. Took it to Autozone and changed the battery since the guy told me it was BAD (AC Delco). I changed it for the Duralast Platinum and it ran perfectly for about a month until last week it did not start again. So here is what happened: I went to my car pressed the unlock key in the remote and it worked fine the odometer and the jeep sign showed in my dash. I put in the key and crank it up but it turned everything off no more odometer and no more jeep sign. There was not a single volt of power in the car. I took my battery to AutoZone to check if everything was fine and it was in perfect shape with around 12.7 volts. I put back the battery and left the car disconnected for a couple of hours and connected back in and it worked fine. I took the car to the mechanic to check on the electrical and he mentioned everything was fine. The car has been running fine but I am scared that this happens again in the future. Has anyone had this trouble before?

Thank you,

 

I would check your battery cable at the connectors. It is sometimes hard to spot when they start to corrode and loose connection.
Sorry, I quickly read your post, thought you had a starting problem.
