I bought a used 2009 Prius in early this year and I had a couple of issues. First, the headlights would randomly cut off. I took it back to the dealer and they replaced the lights which led the the second issue. A strong smell of gasoline in the cabin and a quick loss of fuel. After returning to the dealer and having the service manager confirm the smell, he had it checked out and what he told me was that the fuel hose had some excess plastic one the clip at the end of it. They "fixed" the problem and it ran well up to this point. The smell returned and the fuel gague is quickly dropped again. so after returning it to the dealer, he told me that the fuel line is "worn out" and has to be replaced. This car has a lot of miles on it (80k) for a three-year old car, but is this really what I should expect every three years? Has anyone encountered this kind of problem?
