I've owned this 2009 Buick Enclave for 3 months and love the car. Two weeks ago we parked the car in front of a stores and went in for 15 minutes. Came out and it wouldn't start. Jumped it and it started right up and has run perfect until this morning. Same issue after being left just over night. I had the battery checked at two places and both said the battery is fine although the cranking power was at 580 and should be 720. Registered 13 instead of 14 on their meter. Turned the key this morning and it just goes "click" until jumped.
Any help would be appreciated.
