I'm glad I'm not the only one with a recurring dead battery. I have a Traverse LT with parking assist, but no navigation unit. The first time it happened at the end of November, I had Chev Customer Care come out and jump it, then drove to the dealer. They told me it was because I let the car sit for 3 weeks. When I asked them about the software update I read about on here, they just handed me my keys. The 2nd time it happened, I just had CCC come out and jump it. The 3rd time, I had CCC come out and jump it and they towed it to the dealer. This time the car had only been sitting 3 days (and I told them about the jump in between). They found nothing wrong. The 4th time it happened, I called the dealer as it had just been in 2 weeks before and asked them to send their wrecker (CCC dispatches from a town about 1 hr away). They told me to call CCC and I waited 3.5 hrs for a tow. This time, they found a draw coming from the body control module. They had it for over a week because their computers were down. I picked it up, drove 100 yds and all kinds of alarms and warnings sounded. Drove it straight back in and it turns out it wasn't test driven and the brake calibration was off (another 2 days to figure that out). Every time, they told me if I got a survey to fill out excellent, because anything less is a fail. I said I'd have a tough time making a case for average service. The results of the survey must have gotten to the Service Mgr, because he called me and apologized profusely and promised the next 2 oil changes on him. The day I got the card for the free oil changes, the car didn't start again! This time, they say the draw is coming from the seat control. When I pick it up this time I'm going to drive over to their used car lot and sell it.
