Other Fuel System Tank Filling/charging problems of the 2010 Hyundai Sonata

The gas pump nozzle always switches off when I try to get gasoline, making it impossible sometimes to get the number of gallons I need, requiring a guess when the tank will be full because the trigger won't stay in place. Our 2010 Hyundai Sonata was purchased in 2012 and has had this problem since day one, and I see it is a common complaint on the internet among Sonata owners. We brought it into the Hyundai dealership in two different states: neither was able to locate the problem! this is unacceptable. At one point, we could not put any gas in and had to drive it immediately to the dealership. They replaced a carbine cylinder in the gas tank that cost $700.

So I would drive there weekly on the outskirts of town. Twice, I was approached by strange men looking for money or a ride to the casino. Then on this last time it took 15 or so small pumps to raise the needle just a third of a tank. It is a safety issue as an overfull tank could spill toxic petrol on us while we are pumping gas, or leave us with too little gas and no way for the pump to work, and get stranded in a bad part of town or a highways. The check engine light has been going on and off for months, sometimes seeming to be related to the gas cap. Yet the dealerships can't help us and there is nowhere to buy gas that isn't a frustrating ordeal. Unacceptable. . Read more...
