My fuel gauge is no longer reading the fuel level. I fill my tank to full and it tell me that I am empty. Fuel indicator comes on and fuel gauge goes up and down. I have to manually calculate and estimate how much fuel I have left. This is a common issue on Sonata's as there are many others reporting and is not a recall yet.

At any speed the engine will return to idle without moving the gas pedal. It will do the same thing when using cruise. Pushing the gas pedal will re-engage the engine. It acts as if you take your foot off the gas. There are no warning lights and everything acts normal (lights, power steering etc). This started in mid March 2019. It is becoming a daily issue.. my wife is scared to drive it. I took it to my Hyundai dealer and they could find nothing wrong. It did not do it for them. They said it showed no codes. I keep very good care of my Sonata. It has 180,000. My dealer is noller Hyundai topeka ks.

Sonata

  • 90,000 miles
The contact owns a 2012 Hyundai Sonata. The contact stated that the rear tail lights had an internal electrical short and contained rust and corrosion. Also, the sockets melted on both sides of the rear tail lights. The rear passenger side light had to be removed to prevent the middle rear brake light from remaining illuminated. The rear driver's side tail light was operable, but eventually shorted out as well. The contact ordered replacement tail lights three times, but the failure recurred each time. In addition, the contact heard a loud noise concerning the fuel system. When turning the steering wheel in either direction, the contact heard an abnormal noise intermittently. The vehicle was included in NHTSA campaign numbers: 18V137000 (seat belts and air bags) and 18V934000 (engine, fuel system, gasoline); however, the contact did not receive any notifications. Mcgrath city Hyundai (6750 w grand ave, Chicago, il 60707, (773) 889-9090) was contacted, but had not diagnosed or repaired the vehicle. The manufacturer was notified of the failures. The approximate failure mileage was 90,000.

While driving or stationary the gas hand goes down from 367 to 0, ----- when I know there is gas in the car, sometimes the gas hand will come back up to where it belongs and when it does not come back and you keep on driving the engine light comes on. Once you fill the car back up about $4 worth that is all it will take drive the car for about an hour the engine light goes out, but the gas hand still will go to empty after you reach about 300 gas to empty.

2012 2.0T limited with 95K. 12-18-18, while driving from austin to houston tx vehicle loses acceleration on the highway. Check engine light comes on, along with the emergency parking brake light (which comes on intermittently and dealership yet to define problem), and abruptly goes from 75 to 0 mph. Vehicle will not respond to any acceleration and I have to find a way from the freeway to feeder without power. Inoperable. Limped three miles with police escort. Car towed. Dealership cannot duplicate issue. I make them keep vehicle to investigate. They get a code error and change out the ECM for a mere $1400. Meanwhile, I must find transportation in a city I do not live and rent a car for a week. Retrieved vehicle. 2 weeks later, traveling to houston on 12-26, check engine light comes on, car will not accelerate; spitting, feels like no gas getting to engine, heavy smoke from tailpipe. Christmas eve, no place to stop. Barely make it to houston. Inoperable. Car goes to another dealership in houston. Again, without transportation in a city I do not live in. Faulty high pressure fuel pump. Carbon buildup. Another $1100. Prior to that, March 2017, engine failure travelling to houston. Knocking noise. Wont go. Inoperable (luckily, this one I made it to a full stop). Car towed. Waited three months for a new engine (not in my hometown). Had to travel to pick up vehicle. (car had been inspected by hometown dealership specifically for metal debris and it did not get flagged for replacement). Directly after that, while driving in austin. Vehicle stops in major intersection. Inoperable. Towed. Degraded battery cable because the vehicle sat for three months while waiting for an engine. The only warranty was the engine. Can you say lemon? the only saving grace is that myself and my family were not seriously injured when our vehicle became inoperable while driving on a highway.

The fuel gage does not register then it acts erratically - going from full to empyt to 1/2 tank then remains on empty - all this within 20 min. Of filling up the tank. I have read forums it is not limited to my car. There are many Hyundai owners that have the same problem. There should be a recall for this - its not limited to Sonata - Santa Fe models reported it too.

"fire hazard" received an engine replacement under Hyundai engine recall, I picked-up the car on 09-13-18. I've had several problems occur in the last few months. One of the main issues is a fuel/gasoline smell inside the cabin and around the engine compartment. Now there is extremely strong smell of gasoline whenever I just turn on the ignition without starting the car. I also notice that there was a puddle of gasoline on the ground under the engine area. I read that some cars are catching on fire after Hyundai replaced the engines under the engine recall. My concern is for safety of my family. There is potential that my car may/will catch on fire. The car has not been driven in over three weeks. I've filed a complaint on 12-03-2018 with Hyundai motors(case # 13222827) but have not received any updates as of yet.

1.) I have been having issues with the fuel light flashing as if I am out of gas, when I just put gas in the vehicle. I had the fuel pump changed and that does not fix the problem. So now I am in the process of trying to find out what the problem is. 2.) I have received a letter that there is a recall on the air bags, my air bag light is now on and stays on. When I checked online it shows that there is not any remedies available. I drive this vehicle everyday with my 3 children in the car. Heaven forbid I get in a serious accident and the airs bags do not deploy, who knows what may happen. This issue really needs to be corrected. 3.) I noticed on the recall list that my vehicle also has a recall on the seat belts as well; another safety issue if I were go get in a car accident.

The electronic fuel gauge does not go below two bars. I was in motion on a highway street and the car stalled. I did not know what was wrong. The tow truck driver put one gallon of gas and the car started up again. I now fill up my car way before it gets down to two bars on the gas gauge.

Sonata

  • 48,000 miles
While in motion at low speeds, the car failed to accelerate and the engine performance was extremely poor. After slowly accelerating, the car would then "sputter" and the engine would lose power (while the car was in motion), causing the car to nearly stop on the road without warning. This caused traffic to back up on the road, and forced cars behind my vehicle to slam on their brakes so as not to rear-end my vehicle.

Sonata

  • 100,000 miles
While the vehicle was stationary (idle at a stoplight), the vehicle turned off without warning. The vehicle then had difficulty starting after the incident - leaving my car sitting idle in a busy intersection. In addition, due to the same mechanical error, my car while in motion (on a highway going about 65mph), the car had difficulty maintaining engine power and "sputtered" several times before resuming normal performance. This resulted in my car moving at speeds that were under the posted speed limit, causing vehicles behind me to have to brake quickly to avoid rear-ending me. Finally, again due to the same issue, the car had difficulty starting (while not in motion).
