2011 Hyundai Sonata: wrong fuel gauge reading

Filed Mar 7, 2024 · IL

Gas gauge worked, only, intermittently. Would indicate empy after a fillup. At about 3/4 of a tank, would start showing accurate reading. Now seems not to work at all. This has been going on for 2 years. Now, it is stuck on 1/2 full no matter how much or little fuel is in the tank. My safety concern is running out of fuel on the highway and being rear ended by another vehicle. Online, I have found. Many others complaining about this issue.

My 2011 Hyundai sonata Engine failed in April 2023. Was towed and the engine was replaced due to the recall. Got car back November 4th 2023. Fuel gauge never went out and after driving about 3 miles the engine light came on. Dec 13th was driving on highway and felt like the car was going to fall apart. Able to get off highway only for the car to die. Every light including some I have never seen came on. Was stuck on the side of the road with my ESA dog in 28°. Temp. For over an hour with no power and hazards starting to dim. I'm disabled and had no help. Local PD towed vehicle and drove me home. Car sat at tow yard collecting fees as I was waiting for the dealership to call me back. Finally got help with paying the tow yard company only to be stuck once again for over an hour in the cold and then denied a tow to the dealership since they decided to cancel my appointment by text while I was on with Hyundai roadside assistance. They denied any help. Luckily the tow yard felt bad and made a call for me and a friend came and paid the 160.00 tow truck to get the car back to my house. They have now not returned my calls and the case manager has not responded as well. This is unacceptable. I don't have any money and I have no idea how they can get away with treating a disabled person in the winter days before Christmas by letting me be stranded twice on the side of the road with an engine that has less than 10 miles on it.

I was driving my car on the highway and it suddenly shuddered while I was going 70+mph and the engine light came on and kept flashing. I had to pull off to the side of the road and call for service. I took my car to my local mechanic who told me it was a knock sensor issue and it had to go to the dealership for repair. I then had it towed to the dealership where they told me my motor needed to be replaced. The dealership had my car for almost 3 months to replace the motor. The next day after I picked up my car from the dealership for the engine replacement my battery quit, my headlights quit and my passenger side window motor quit. These were all working fine before the engine went out. Then on the Monday after my check engine light came on. I took it back to the dealer and they told me it was an EVAP sensor that needed to be replaced but wast part of the engine replacement so I had to pay for it to be repaired. They had my car for another week and replaced the sensor. One week exactly after getting it back for the 2nd time my check engine light came on again. The dealership told me it was the EVAP sensor again but they had to call technical support to get a plan to fix it. They told me it was perfectly fine to drive while they are waiting to hear what to do from technical support. The car is now parked in my driveway because I can not physically put gas in it and the one time I was able to put gas in it, I drove approx 120 miles on a full tank of gas and my low fuel light came on and it shows little to no gas on the gas gauge. I am afraid to drive it because I am afraid it will catch on fire or I will mess up the fuel injectors or worse.

The fuel gauge on the dash board stopped accurately showing how much fuel is in the tank. The tank may be full, but the gauge will show it as half full, or three-quarters full. Sometimes it changes mid-drive, and starts to go up. I can't trust the gauge anymore.

Fuel level sending unit fails constantly. You never know how mich fuel you have in the vehicle. Estimating the mpg is nearly impossible because it varies greatly. I've ran out of gas several times in dangerous highway situations.

After putting gas in my car the gas gauge is everywhere. I can stop and restart my car after filling it and it will say I'm empty. Whether I'm actually driving at the moment or stationary, the gauge will constantly move up and down. I have to keep an eye on my mileage to know how much I really have. It has been happening for over a year now. I've seen other stories online of many others having the same issue.

Gas gauge goes from empty to full back to empty and it continues to do so. I have a full tank of gas and it says it's empty. The light comes on and even the check engine light comes on and goes away. It happens in park or while I'm driving. Streets or highway.
