“I own a 2007 Toyota Prius. I cannot fill up the gas tank without it having an overflow of 1-2 pints of gas onto the ground. It seems to build up a back pressure and kick out the gas I try to put into it. If this is happening to other Prius owners as I read it is on the internet, we have a severe environmental hazard occurring from this gas tank defect.”

“Our daughter was driving our 2007 Toyota Prius to work in the dark in rush hour on the highway, driving straight, at highway speed, in los angeles, and the instrument panel instantly blacked out, with the car completely dead and halted. It could not even be shifted into neutral! The car stopped right in the middle of the highway. She called 911, and a wrecker was dispatched to lift the car off the freeway. Thankfully she was not injured or killed! I then researched the likely cause and diagnosed it exactly. It was the hybrid water pump also known as the inverter pump, part #g9020-47031. …”

“Approximately 7 months ago my 2007 Toyota Prius began accelerating during use of the cruise control. I reported the problem to the dealership who said they have no fix for it. I can't use the cruise control in my car for fear the car will not stop accelerating.”

“Vehicle does not achieve advertised fuel consumption performance. I have complained about this since the first service visit. Today a factory technician got unachievable results suggesting that our real world experience after 29,000 miles with the vehicle is normal. He claimed to have gotten 66.984 mpg after a 42.2 miles of 55 MPH highway and in town driving, noting only that an out of fuel fault had never been cleared.”
