Since day one I can only put 20 gallons of gas in my car and I paid more for a 30 gallon tank. It takes forever to fill up as it shuts off ever 2-3 gallons. I have had the dealer replace a nozzle twice now, and they say they can't fix it. It is very much a pain especially since we use it for business. I paid cash for it so I would take a beating if I sold it. I love the overall vehicle but I am very disappointed in the service I have received. I have been too nice.
We had the same problem. We removed the fuel line and cleaned it, it was clogged. Wouldn't hurt to try that, very simple to do. Much easier than standing at the pumps so long.
