Yah, had similar issue in PITT: drove 35 miles in Hertz Prius, replaced gas myself...four gallons worth!! Are you kidding? Hybrid = save the environment? NOT!
Plus, stupid hybrid doesn't generate any heat until the gas motor engages...and that day, it was -2 degrees F. Froze my a** off getting from hotel to Hertz to drop that peice of cr** off.
Hertz chick told me that about 90% of the time someone drops off a hybrid, they say "How do I make sure I NEVER GET ANOTHER HYBRID WHEN I RENT WITH YOU GUYS??!!"
