Other Fuel System Tank Filling/charging problems of the 2009 Hyundai Santa Fe

Fuel guage does not work properly. Fluctuates greatly causing potential safety issue if one were to run out of gas on the highway. Check engine light on after filling gas tank.

After filling gas tank the fuel gauge went to empty and the check engine light came on. Bad fuel sensor.

Check engine light is on and gas gauge shows empty even after filling up tank. The problem started at around 100,000 miles ( give or take) mechanic said it the fuel sensor on driver's side as per electronic reading. A recall must be issued for this dangerous defect. Its plain to see its a common issue. I already ran out of gas during my morning commute on nyc westside highway & fdr drive, I literally almost died the 1st time it happened.

After filling my gas tank, the fuel gauge on my 2009 Santa Fe would read empty and the low fuel light would illuminate. In addition, the "check engine" light came on. After driving a few miles the fuel gauge would fluctuate between empty and half full. The mechanic checked the onboard computer and the code said it was the fuel sensors. He replaced both of them, at a cost of $500, and it seems to have solved the problem. Mileage was slightly under 100,000 miles.

After filling vehicle with fuel, fuel gauge showed tank empty and yellow light on dash shows fuel empty. Fuel gauge recovered to show 1/2 full, then displays erratic results. Online forums show defective fuel sensor with a large number of Hyundai vehicles. There should be recall on this issue. Drivers may think they have sufficient fuel, to then have vehicle run out of gas in a dangerous driving environment.

After filling the gas tank, the gas gauge read empty, along with the low-fuel warning light. After driving approximately 10 miles, the gauge then appeared to be functioning normally. The gauge continues to malfunction if the gas tank is filled. When the tank is below half full, the gauge will randomly read empty or half full. An internet search quickly revealed that many owners are experiencing this problem. I hope Hyundai will initiate a safety recall too correct the issue.

Once the gas gage reaches 1/4 full, it goes to empty. After filling with gas, it will take over 1 hour to record a full tank. Cannot use the gage as we are never sure how much gas is in the tank. The engine light also appears and stays on until the gas sensor records full.

I have 2009 Santa Fe. This happened first time in February 2014 that I was filling gas (I always do full) and as I started leaving the gas station my fuel gauge showed empty. I went back to the gas station and ask the attendant that there is a mistake, my tank is not full it is empty. But I was wrong, because he told me there is no way the pump machine will lie and he fills 100s of vehicle per day from each of his machine. Just to double check, the next filling I used a different gas station and it happened again. Now this has become routine and since my last two visit at pump, even the check engine light is coming on now. I have to wait few days and mileage to put on that the check engine will go off but the fuel gauge will still show less than half the tank. At this moment, I know my car and can predict with some degree of certainty about the mileage my car will provide but as the car ages and other things in the engine ages, it will become more difficult to predict the gas level. So I might be in trouble stranded on highway or in city during rush hour. Also I found online that this is not just my problem, many of other Santa Fe had similar issues. Therefore, I thought I should also share my experience here.
