My2007 Prius was totaled in December and I purchased a 2009 with approx 52k miles. I'm driving the exact same route to and from work - and granted it is a stop and go short commute, but the 07 averaged 44ish mpg and I'm lucky to get 32 in the 09. I've checked the tire pressure - they were all incredibly low but correcting this has only made a slight improvement. It's clearly going for service very soon but I just wondered if anyone has a clue about what the problem could be.
Please answer the questionnaire listed in this post: http://priuschat.com/forums/gen-ii-...e-questions-esp-if-youre-new.html#post1074322 It helps eliminate the typical mileage problems leaving specific problems that some of the technical experts can help diagnose.
Most likely it is the 12V battery. Particularly, if you bought it from a dealer instead of a private party, there is always a valet, salesguy, detailer etc. that runs the battery down, and all they ever do it jump it, instead of charging it.
