I am having the same problem with an AWD crew. It had a dead battery early in 2012 and I had it jumped. No problems until the battery was dead again in November 2012. It happened twice last month and now every day this month it has had a low battery and needed to be jumped. The vehicle started once today after driving for about 70 miles and letting it sit for 6h. I just drove it for 5 min and now it won't start. I have a service appointment tomorrow. I will post the results as soon as I can.
