Well, I've had my battery replaced twice because it was killed, and had the TSB to keep the display from waking from sleep mode already done. This morning I woke up to another dead battery.

Based on that poll, it looks like less than 30 people have had this problem. Does that seem about right?

Thanks mbedit. I'm planning on going away for the weekend, and either have to leave it sitting in the driveway for 3 days, or drive it 3 hours away from my home. Neither one make me feel very comfortable right now. Will probably buy a portable jump starter just in case and hope it was only a defective battery. I would have assumed that at first and not worried about it if I hadn't seen all these threads.

Oxnard...is this a TSB that wouldn't show up if he searched for C-max specific TSB's? Because I asked him about that (without having the specific TSB reference number) and he said the first thing he did was look for any service bulletins since the car is so new. I'm a little nervous about this dealership's knowledge base, frankly, because he told me this is the first C-max he's seen in his garage and he only has one hybrid certified mechanic...

I've got another one to add to the list. Bought our C-max SE with winter package as the only added option on Saturday, March 23. My wife tried to drive home from work yesterday (March 26) but found the battery was dead. Roadside assistance got us to the dealership today, who said that we had a bad 12V battery (failed load test) but they didn't see any TSB's for the C-max. Also, they didn't have any C-max batteries in stock, so we won't get our car back till tomorrow. My question is: of the people who have been told that they "just have a bad 12V battery" and had that replaced, has that completely solved the problem for anyone, or does the problem always resurface? I don't want to get the car back tomorrow if it's going to happen again two days later.
