Engine stalls at high speeds and slow down dramatically. Have taken to hyudai twice, they say the engine recall has nothing to do with stalling only knocking and they want to charge me $104 diagnostic charge when clearly all the newspaper say that it possibly has debris which can clog fuel lines and cause stalling, they said this in not covered under the warranty or recall. It has happened numerous times in the past three years, but they won't do anything about it. Last time is listed below

The vehicle has always had a slight knocking noise coming from the engine. I thought it was just a sound from the engine rev as you accerate. Then as I was accelerating pulling from my drive way there was a loud knocking noise coming from the engine. You can hear it after slowing down under 7-10mph, then accelerating again. Now you can hear the knocking noise as the vehicle is warming up in the morning. The noise fades after 10mph.

Car kept shutting down not wanting to start due to gas pump. I would be driving and would start stalling while drive almost crash. Electrical problems the light flinger on and off while driving and when switch them with a loss of power steering assist, extra steering effort will be required, especially at lower speeds, increasing the risk of a crash.

My car has been blowing out white smoke out of the exhaust. I seen there has been alot of recall issues on the Hyundai. I got a letter informing the recall of the air bags. I bought this car in September 2017. I dont know if the previous owner had the issue fixed on the recalls about the engine, brakes, and seat belts.

Vehicle is hesitant to crank. I have to hold switch a few seconds before it will start. I have taken it to the shop and they said it needs a new fuel pump and that this is a very common issue with these types of car.

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.

I have had two separate incidents where my vehicle's engine completely lose power while driving. There is no warning and the steering locks up and my car is immediately disabled each time I came extremely close to being hit by on coming traffic.with the incident the car suddenly start slowing down and when I pressed the gas pedal nothing happened but all the sensors popped up I was able to pull over just as it lost power and the car wouldn't restart and I had it towed. Few days later car started as if nothing happened I began to drive it again but after about a week I was on the highway during morning rush hour attempted to cross lanes and it suddenly lost power again and I couldn't move the vehicle at all I feel very unsafe driving the car beacuse this happens randomly and without warning

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.

I have noticed a very strong smell of gasoline. The smell is so strong that I had to roll my windows down because I was starting to get dizzy.

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

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.

Fuel gauge and fuel pump sending unit. Safety issue with the fuel gauge as it will not accurately show fuel level and will sometimes show empty because of a faulty fuel pump sending unit. The warranty on this vehicle should be extended to repair this safety issue. This started approximately two years ago and has gotten progressively worse.

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 contact owned a 2011 Hyundai Sonata. While driving approximately 70 mph, the engine seized. When the accelerator pedal was depressed, the RPM gauge needle was in the red. The contact stated that the driver was able to pull the vehicle over to the side of the road and noticed smoke and flames under the hood. The fire department extinguished the fire. A fire report was filed and no injuries were sustained. The fire department stated that the cause of the fire appeared to be caused by fuel leaking into the engine block. The vehicle was towed to an impound lot and deemed destroyed. The manufacturer was not made aware of the failure. The failure mileage was 101,000.

On March 10 I took my Sonata to get an oil change at superlube. I also took the car on the 11th to the Hyundai dealership to check for a knocking noise I had heard in the car. They ran tests and told me my engine was fine, and I need brakes, an alignment, and tires. So I spent $800 getting these things done on my car including the oil change. Well on the 18th of March in traveling my car stopped in the middle of the highway. I crank up it drive for a minute and cut right back off again. So I had the car towed to my house. They ran tests, could not find anything wrong with the car, thought it was my pulley, but it was all right. So the mechanic said let's try another oil change. Started draining the oil, it was black as tar as if I had not gotten an oil change. Treated the gas and the fuel injection system. Still a knock in acceleration. Went back to superlube to give them a piece of my mind only to find out that the manager had been having problems with gdi engines and the fuel injection system. Told me that they knew about it and-and not saying anything. I was only mad because I had taken my car to Hyundai twice since I had the car in a year for engine inspection and not one time did they tell me this.

When I accelerate on the freeway, engine stalls. Goes from 55 to zero and when I pump vigoursly in the gas to make it go faster, it will not. I almost was slammed in the rear from other cars in the freeway. Plus air bag light will not go off. Plus knock knock noise heard in the engine.

Our 2011 Hyundai Sonata gls 2.4 engine caught fire as my wife was returning home from taking our son to school. My wife smelled gasoline and then it burst into flames. This was the second replacement engine covered under warranty and had less than 6000 miles on it. Hyundai mall of Georgia has performed all warranty service work on this vehicle. After the second engine and many other warranty repairs tried to envoke the lemon law but was denied by hyundia case #9412898.

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.

Fuel sender (in tank fuel sensor) has failed. First noticed over a year ago with intermittent erroneous fuel gauge reading after refueling, but quickly corrected its self. Noticed the full failure a day after I had refueled and my fuel gauge read half full. Assumed that I was a victim of fuel theft, but no sign of forced entry to my fuel door. I refueled and the car topped off within about a gallon. However the gauge was still reading low. Assumed that maybe the thieves had damaged and partially obstructed my fill hose with a lost syphon hose. Over the next few days the gauge slowly rose to full. Now the gauge fluctuates between full and half full. Researched the sending unit and found that this was a known problem with three models and a tsb (sb-10052842-7701) for inspection of the unit was issued May 2013 and a replacement procedure (sb-10060967-2273) was issued June 2014. Aftermarket replacement part is affordable at approximately $45 from third part vendor, but the replacement procedure is complicated by the high risk of working with gasoline and either trying to remove the fuel pump in the tight confines of the car with the fuel tank still installed or removing the tank with residual fuel.
