I have a 2009 Dodge Journey SXT. New radio installed and recently the battery has enough juice to turn on the interior lights; but, it won't turn over. There are no error codes to report to mechanics. They had it after the first instance and couldn't rplixate the problem. Two days later, it needed another jump still no error codes. 6 days ago I had 2 engine lights: ESP Bas and an icon that looks like a car and tire tracks. Yesterday, the truck wouldn't turn over and pop-a-lock double jumped it to get it running: cables on the connectors via their box and cables on the battery from his battery and it worked! Just dropped off vehicle to mechanic to hopefully recreate the problem. If they hadnt told me to drop it off with a free loaner, I would have paid for a full engine diagnostic tomorrow. Any ideas on what wrong? It only has 68k miles, I bought it a month ago and so I'm a little concerned on how to handle
