Two problems related to other fuel system tank assembly have been reported for the 2009 Toyota Prius. The most recently reported issues are listed below.
Unable to add any gas to the fuel tank even when tank is near empty. Gas just spurts back out of the filler neck. Over time we have learned that this is temperature related. At or near freezing temperatures and colder it becomes impossible at times to add any gas to the tank. The only way to add fuel is to get the car to a warmer location and let it sit for a few hours. We have detailed records documenting several instances where we could add no fuel and many instances where a near empty tank will take only 1-2 gallons. The car has been seen by two different Toyota service centers but they claim they can find nothing wrong. Toyota USA has stopped responding to our requests for help. We are unable to trust the car for extended trips in the winter due to fears of getting stuck with an empty gas tank. A (related?) problem is that the fuel level indications are not consistent and thus cannot be trusted.
2009 Toyota Prius, car has had a bad fuel gauge , drove off the lot new and have had fuel tank replaced once. Fuel gauge failed again this is the second time. Dealer unable to repair, told me it was a design flaw and it could not be repaired, I am running out of gas and I can not use this new car on a long trip. I do not know and I am guessing on how much fuel I have. This is unsafe and uncalled for. Running out of glass on freeway and it is dangerous.
