I rented a Prius 2 for the day because I'm very seriously considering buying one. I really enjoyed the car. My only problem was with the HV battery fan. The noise coming from the vent by the rear passenger seat was quite loud at times. I've read that the fan has different speeds and only becomes noticeably loud at the top speed. I was wondering how much of a problem this would be? Does the fan become loud very often? Do Prius owners have problems with the noise? Are there ways to keep the car cool so the top fan speed isn't necessary? I'd greatly appreciate any feedback on this. I'm planning on buying the car very soon and am only hesitating because of this issue. Thanks for all the help. If the responses I get reassure me that the fan noise isn't a problem, then I'm looking at price for a Prius 2 of 25,200 Out the Door. Does that seem reasonable to people? Thanks again.
