“The gas tank wii not allow you to put gas in it. When you try to put gas in it won't go down in the tank hose and the fuel gauge is ready a 1/4 tank. The car jerks when pressing on the gas pedal. I have only gone around 200 miles and gauge fluctuates with different reads so you don't know exactly how much gas is in the gas tank. The engine light is on as. This is happening while I am traveling.”

All tires were clear so she proceeded to work cautiously, on her way home she noticed her check engine light had come on and noticed there was some road noise coming from the back. She then called me, note this is the first I heard of the situation. …”
