The disgusting thing about random events in mathematics, is that over any "segment" of the series of random events, you may find a pattern.  It means nothing in the grand scheme of things, but it does pee one off sometimes!

The good thing about random events, is that the belief they happen in groups isn't true.  However there is nothing that prevents them from happening this way.

if the weather got really cold suddenly it would explain the multiple dead batteries. 

In good weather even a marginal battery will start a vehicle, but as the weather gets colder the amount of power a battery can release is reduced, and the amount of energy required to start a vehicle increases.

How many batteries are in your family?

Then the odds are 3:X.

You're welcome.

And I don't even know,  but the odds are they were all passed the pro-rated warranty by two days.

I have my personal rule that if the battery has lasted 5 years it's a throw away.  If it hasn't it's not your fault.

I changed them regularly on age.  The second thing I found from personal experience, is that to get maximum reliability for cold weather starting, use fresh oil. 

The moisture that collects during cold weather short trips makes the oil like sludge, and produces hard starts.  Oil is cheaper than a trip to the service garage.

The definition of a successful modern product.  Computers are wonderful for designing with no margin for overdesigning.

Whenever a young person got killed in a car wreck or whatever when I was a kid, the old ladies always said 'it happens in threes.' Well sure it does if you start counting at one again after the third one.

Sears once seemed to slightly undercharge for a five year warranty battery, which would almost certainly get you back to the store for a replacement under warranty at the four year mark.

So to do the odds, I would place the odds of it happening at 100%, because it DID happen.

I argued with a Subaru dealer this way.  He said Subaru's were very reliable, I said mine spun a bearing at 16,000 miles.  He said this wasn't normal, I said it was for mine.

I only had one and it soured me on them all.  None of my other vehicles over my whole lifetime did this to me.  So my experience was 100% bad.

i always  hear how great they are , buddy bought a cross trek  when they came out , man he had nothing but trouble  after over a year ans lawyer they finally  placed it under lemon

law ,  then he said i dont want another one i want my money back ,  so after another year of fighting , he hired  4 or 5 dudes to picket with signs on the roadside in front of dealership , a week later he said he got check in mail .     if i ever get screwed thats what im gonna do .

Never had trouble with a OEM battery. Some have lasted over 8 years. Knock on wood my luck holds.

I bought two new vehicles in 2011, about a month apart. Two years ago, one of them had the battery just die like a light switch. It was absolutely perfect one day then the next, nothing. I mean not even enough voltage to unlock the doors, light up the dash, or anything. I had to figure out how to get to the shifter interlock release to get it in neutral so I could push it back enough to get a jump. I stopped on the way home and bought another battery and switched it in the parking lot. 

The next day, I took the other one to replace the battery as well. That one had shown no signs of getting weak but, was a month older, had a smaller battery, and even more electronic wizardry than the other one so I figured six years was a good run. I've seen plenty of them fail in just three.
