Other Fuel System Tank Assembly problems of the 2011 Hyundai Sonata

1. The car began to randomly stall and stop running. This happened while driving and it was extremely dangerous. Typically, the engine would restart after at least waiting 15 minutes. Any attempt to start the car before that time would fail. 2. When the stalls happened, the car acted as if it had run out of gas. The engine would simply stop running without warning, at intersections, on city streets, and on the freeway at high speed. It did not matter how full the gas tank was. 3. My brother and I diagnosed the problem as intermittent loss of fuel pressure. 4. My brother and I replaced the factory fuel pump, and to hour horror, when we unplugged the electrical connection/plug, one of the pins from the fuel pump came out with the plug/connector. 5. We inspected the fuel pump and discovered that parts of the electrical plug inside the fuel tank had become burned and melted. See image sany0135. Jpg === this is a safety defect - either the internal fuel pump electrical connections were faulty from the factory or the problem developed over time. There have been other recalls for this model of car for random engine stalls but this is a new and different cause. A dealer with a relatively inexpensive infrared camera could likely spot this problem with minimal vehicle disassembly. There was clearly a lot of heat concentrated in the area of the electrical connection to the fuel pump. We hope this report triggers a recall and prevents extremely dangerous random loss of engine power events, fires, or worse. Please recall all the vehicles that used that fuel pump for inspection before there is a disaster.

1) seatbelt latch will unlatch while driving. 2) the fule light indicator is never correct show empty all the time. Will go to full and back to empty while driving. 3) while fueling the pump will jump off before soon as gas starts going into tank. 4) struts are not working all 4 are out and down hitting the roads hard while driving. 5) paint is peeling off al th sides back panels while driving.

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.

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.

My fuel sending unit has failed. My "miles to empty" meter is never accurate or steady. It's always moving sporadically. I have to constantly keep my tank fill in fear of not knowing how much gas is actually in my car. Also, my airbag light is on. It just randomly came on when I was driving. I'm not sure if this has anything to do my seat belt or a faulty sensor. Both of these issues both happen when the vehicle is or isn't in motion.

Fumes in cab while driving causing burning nostrils, headache, bad taste in mouth, gagging and nausea. 2 different Hyundai dealer service departments have told me it is normal for the plastic gas tank to vent the fumes in hot weather to prevent the gas tank from exploding, and there is no repair for it. I don't know how it is safe for the driver to be breathing in those fumes. I have to park the car and get out so I can breathe. This is normally on days when the temperature is above 110 degrees, which is often in las vegas summers, and normally happens during city stop and go driving, but has also happened during highway driving. This happens with our 2009 Hyundai elantra under the same conditions, as well, but the fumes are not as strong.

I am a owner of a 2011 Hyundai Sonata and my fuel gage fluctuates showing at times I have gas and other times that I have no gas. My fuel tank only lets me put in no more than $10 at any time. I do not know any owners of the same make and model to compare this to.

The fuel gauge is not working properly from 2-3 months and I started noticing it by early June 2016. When gas is filled, it displays the full tank gauge. But after stopping at any place and then starting the car, the fuel gauge drops by few bars to half a tank. Next morning when I start my car to go to office it would show empty tank with gas light on but will correct itself to few bars to half a tank to full tank. I had visited Hyundai dealership on oct 12 2016 and they said its out of warranty by 62 days and my extended warranty of 100,000 miles only covers engine and transmission. They also said it will cost 750 plus $ to replace the "fule pump" to fix this issues. To avoid any empty gas situation I always rest my trip b to zero, after full tank.

At random times the fuel gauge will show the car is totally empty and the fuel warning light starts flashing even if the car has over half a tank. After sometime it might go back to normal. When flashing empty and I get gas, the tank will trigger the pump that it's full after only a couple of gallons and the gauge will show the tank is full. I have started resetting the trip odometer after each gas station visit, and making sure I don't go over 150 miles.

2011 Hyundai Sonata limited 2. 4l. Ever since I purchased the vehicle from the dealership in bloomington,in five years ago I've had a difficult time getting fuel to pump into this car. I can't even put it on the lowest gas pump setting and it will disengage the pump over an over again. Literally, most times only being able to put 5$ in at a time very, very slowly, with some gas stations leaving me unable to pump at all. I've complained about it over the phone for years. After going through cancer treatments, I finally went to the terre haute dealership for the first time instead of bloomington, also for more recall issues. They found the gas pumping problem and said it's the canister and valve near the gas tank that needs replaced quoting me $548. 65. Of course there's no warranty now at 140,000 miles. Once again left to do the work myself, as the part is really cheap an easy to fix. I don't know how one can justify that price. . Tired of all the crazy issues with this vehicle.
