Not many seem to know the solution here. After much research online and going to a mechanic site. . . I spent $250 on a canister,,, valve. . . And filter. . . That was suppose to fix the problem. No go there. So now I much contact Hyundai again. . . . After their only advice was to bring it to a dealer. The dealer sold me the parts and said that this would fix it. Just want to point out that there are many consumer's online that are searching for an answer. Imagine all of a sudden. . . . Your car that you have maintained and kept in good shape. . . No longer lets you put gas in the tank.
The contact owns a 2002 Hyundai Sonata. When fueling the vehicle, gasoline regurgitates from the fuel tank. Also the check engine warning light was illuminated on the instrument control panel. Sometimes the vehicle will hesitate when attempting to accelerate, as if there was no fuel available. The dealer was notified, and a technician concluded that she would have to pay $900. 00 to repair the vehicle. No repairs were made. . The failure mileage was unknown and the current mileage was 82878.
Engine light keeps coming on. Took for repair and the code states there is a problem with the air/fuel mixture. Auto repair shop asked if we turned the gas cap atleast 3 turns after last fill--yes we did. We previously were not able to pump gas the pump would shut off everytime we tried to pump. Auto repair replaced charcoal filters in the neck of the fuel tank has run fine since this engine light started.
