I adore my Prius, but after 100,000 miles, its mileage is definitely decreasing. My driving habits are very consistent, so I know what kind of mileage I get under what conditions. Until last I was getting an average of about 53 mpg during the summer months. This year it's more like 45. The Toyota dealer says it's working fine, but I worry about my baby.

Even allowing for AC. Because I drive exactly the same stretch every day, I know what kind of mileage I get at different temperatures. My husband thinks maybe they're putting more ethanol into the gas mix and that's cutting down on my mileage.
I couldn't say. I drive an Insight, which is a completely different hybrid technology, and I've been getting the expected mileage from it since I've had it. Of course, it's only a couple years old and only has about 14,000 miles on it.
Maybe you have an engine problem, or maybe the batteries are getting old.
I have an Insight forum that I read and post on. Maybe you could find something similar for the Prius and post your issue there.

The *rumor* was that they were shifting more of the load to the gas engine in order to do this.
I haven't done the research to see if this was ever verified or not, but you might want to look into that.
