Just bought a pre owned '12 edge sport with 36000 miles 2 weeks ago. Experiencing similar problems. Went to go to work Tuesday morning and the car was dead in the garage. Jumped the car and everything was working fine. Let it run and took it for a spin to charge the battery a little bit. Came back 1 hour later to check and it wouldn't turn over. Couldn't even get into the car without using the actual key. Lights worked stereo worked but the engine was clicking and could not turn over. Hoping the battery is still under warranty but I'm not convinced that is the root of the problem. This is ridiculous. Not to mention the brake booster I just had to get replaced on Monday.
