2009 Hyundai Santa Fe: wrong fuel gauge reading

Filed Sep 30, 2022 · Fuel system · KY

The vehicle's check engine light came on and the fuel gauge shows "E". I did an OBD scan and it shows the fuel sending unit has issues. The gauge will work intermittently and the check engine light will go away. Further reviews from others show the same issues with their vehicle with each needing a bad sending unit replaced.

Check engine light on for failed fuel level sensor. Gas gauge is erratic. When I start the car the gauge falls to empty. Never know exactly how much gas I have. Very costly to repair.

Fuel gauge became erratic and triggered check engine light to come on also it will fluctuate a little bit when it hits the 1/4 mark and the low fuel light will come on. It will go from 1/4 to empty can not tell how much fuel is in the tank. When I fill the tank it registers empty and the and the low fuel light indicator comes on. Starting the car again on the same day or the next day, the gage comes up again to the full or half way mark and the light goes out. The car stalls while in city traffic causing a dangerous situation another car could crash into me.

The fuel gauge varies widely. It is difficult to know at times how much gas the car truly has. This seems to by a systemic problem with this vehicle.

Gas gauge highly inaccurate. Fuel warning light goes on and check engine light also appears. Have to pull over as afraid to drive. Finally go to nearest gas station only to find out that gas tank was still half full. This has happened a number of times. Vehicle has only 60,000 miles.

Both of the fuel gauges would drop down to empty wynfall while stationary. If I turn off my car then turn it back on it would stay empty even after being at the gas station. I do not know how much gas I have left in my car and has been on going problem and a safety issue

All of a sudden the gas gauge does stopped reading fual properly.. I never know how much gas I have. On one occasion I was driving to work early in the morning the vehicle studdard I put on my hazard lights and had to maneuver quickly to avoid being hit in the rear. I found out I had run out of gas. Attached is a link with other owners with the same issue. It doesn't matter how much gas I put in it I do not get correct reading. If I put $30 worth of gas in my vehicle it will only read half full. I feel this is a danger because I never know when I run out of gas and being on the highway all of a sudden running out of gas is a safety issue.

For the last year, my fuel gauge has been malfunctioning. At first, it only happened every once in a while, but once I got to about 8 months, the gauge has constantly told me the wrong fuel level. I have asked a mechanic about it and it is the fuel level sensors located in the gas tank that are malfunctioning. Apparently, this is a problem with many of the santa fe's that were built around that time. I have a low mileage vehicle. It was bought in 2016 with 22,000 miles. The gas gauge problem started around 40,000 miles and only happened a few times. The constant check engine light illumination and constant malfunction of the gas gauge started at 50,000 miles and I am now at 60,000 miles. The problem happens when the car is stationary and while I am driving it. I have to keep a full tank at all times just do I don't run out if gas.

Vehicle stalled in road, once on level ground exiting a parking lot going straight and in motion crossing traffic and about to turn left, once on slight decline in motion turning right. After sitting for a few minutes each time, car restarted. Heavy gas smell in car. Fuel senders had both been replaced twice (second time right after first stall) but fuel gage still malfunctioning. Fuel level indication unreliable.

Fuel gauge went up and down. Ran out of gas going 70mph on turnpike it was harrowing. Gauge says full and then empty right away. Fuel sensors need replaced, check engine light is now showing. I notice many others with the same problem. Mine couldve caused a bad accident. Outrageously expensive and cost prohibitive to fix what I think is a safety issue. 70,000 miles is not a lot for this to have happened.

The fuel gauge fluctuates all the time. Sometimes I get a reading but most times it turns on the empty light . I have consulted several hyundai dealers mechanics and been told that this is a big and frequent problem. I have read of so many complaints , that I don't understand why there hasn't been a recall on said defect. .it is as you know virtually impossible and very expensive and dangerous for me to try to fix..I've ran out of gas several times and have been in harms way.
