I've had my first major issue with my Toyota Prius - I can't get the gas flap open. There's no way to open it from the outside, and the inside lever won't open it.
I'm down to about 1 gallon of gas, which gives me about 40 miles before I'm running on electric only. Time for a visit to the dealer.
Other than that I have loved this car every minute!
Update: A 50 cent spring was busted. It's fixed now. Oh, and I'm getting cruise control installed in a week.
