My hybrid battery was replaced at about 75,000 miles. They said it was about $4,000 at the dealer. Of course, I didn't pay a penny, as it was under warranty. I wonder how long this new battery is warrantied for?

Also, I wonder if due to a new battery, I can get more for the car if I decided to sell (which I'm not seriously considering).

Around 45,000 miles I had to get the oxygen flow sensor replaced. Also, the steering column tends to creak really badly in spells, sometimes for weeks at a time, then it will go away for weeks at a time. Really strange. Otherwise, I love the car.

I just got 45.8 mpg (the car showed 49.9) on my most recent tank here in hilly east Tennessee. Tires at max sidewall (44 psi), doing the basics (driving 5mph<SL, DWB, trying to keep accels<2,000RPM). I haven't really tried P&G yet. I live at around 1650 ft. elevation, but most of my driving is at around 800 ft. The drive up the hills to my home really eats into my MPG.
