That's an interesting thought. The car is about 5 years old (or close to it). It appears to have the original battery. I know the key fob unlock/seat position memory thingy seems to somethimes forget that I (6'-3") was the one that locked the door and when I unlock and open the door, the seat moves to the wife's (5'-0") position. So I have to reach down and hold button #2 on the seat to return it to my position. I'd also have to say that sometimes when you start the engine, the starter doesn't spin it quite strong as expected.

I could either A.) replace the battery proactively; or B.) just wait for "that call" on the coldest day of the year telling me the battery is dead. I think I'll opt for "B".

Thanks for the input.
