I was driving on the highway and my engine violently started to shake and I pulled onto the shoulder and the engine shut off. I-??ve had oil leak and engine problems with this car for 2 and a half out of 3 years! I-??ve had to buy countless gallons of oil. Multiple spark plugs, coil packs, etc. You can-??t drive the car for one whole minute without it stalling in traffic and almost causing accidents. So I can-??t drive it!

The car has been having problems with oil consumption. The problem became known in 2022, but the dealer/service department (Frank Hyundai, National City, CA 91950) did not care for the issue or safety. The dealer told me, "Your car is OK." On 7/3/2023, the engine light came on. A second round of oil consumption tests began along with a 90,000-mile service, including replacements of filter assy and gasket, four new tires and front and rear brakes, spark plugs, suspension/steering repair, shaft assy, engine repair, cooling system service, and fuel induction service. Shortly after, the car slows down even when my foot is on the accelerator. It feels like the vehicle will stall/stop (while driving in the middle of the road). I can see the rpm gauge erratically going up and down. The car lurches or jerks. I reported the jerky problem to the dealer at the second 1000-mi oil consumption test, but the dealer did not make any diagnostic tests or repairs because, per the dealer, "it did not jerk while we test-drove it." The problem continues.

In the first incident(2020) after the check engine light was on, the car was towed and needed the valve cover and fuel pump gasket replaced due to leakage. In November of 2023, the check engine light kept flashing and again the car was towed to the dealer. The valve cover was removed and we were told a new engine was needed, but we would have to pay for it. We were old that we have neglected to keep oil in the vehicle.

Car stalls intermittently. When at a stop sign or red light, then when my turn to go I step on gas peddle, car starts to go, then stalls. I have to let off gas pedal and step on it again to get car going. This is dangerous as it leaves me in intersection and vulnerable to oncoming traffic. I had a mechanic check it out and they cleaned Throttle body, but that did not fix problem. No trouble codes showing up apparently.

Hybrid car with various hybrid system failures that results in sudden loss of power while driving. this has occurred 3 times to me while on the highway (I-75 in South FL). Car suddenly loses power, could not accelerate but I was able to get off the highway safety. This has been reproduced at the dealer and they first replaced the hybrid generator then the hybrid battery and ECM and now it occurred again yesterday while I had 2 children with me and now they blame the transmission. This is a dangerous car that should be recalled and investigated for the true cause of sudden and unpredictable power loss.

Noticed a smell of gasoline in the passenger compartment and took it to my local mechanic. Upon his inspection he found that the gas smell was caused by a crack on the plastic connector for the fuel line on top of the fuel pump. He showed this to me and recommended replacing the fuel pump as the connector is built into the pump and there was no proven way to fix the leak. Said leak caused gasoline fumes to fill the passenger compartment and therefore a risk of igniting a fire in the passenger compartment.

I have taken my car to mechanic and they have told me that my car is leaking gasoline. They recommended that I go to the dealer. When I called the dealer they told me that I would have to pay for the diagnosis. This is obviously concerning as gasoline fumes are toxic. There has been no warning lamps turned on this whole time but can definitely smell it when I finish my ride.

Component : High pressure fuel pump Is being fixed as speak ; can provide statement and diagnostic from mechanic. 2. The first time the fuel pump failed it went out on the freeway, I was accelerating onto the freeway and I hear a big pop sound, the whole car went into limp mode. Leaving to cruising on the freeway. No warning, no check engine. I had children in the car. The issue was deemed ; a faulty fuel pump. Second time mechanic let me know there was a crack in the pump ( had been replaced less than a year ago ). Because of the crack, gas & fumes filled the cabin of the vehicle, to the point where you could not operate without having all windows down. The vehicle could have caught fire ! Me and my family could have been hospitalized because of these fumes coming through the vents. Again, no check engine, nothing ! That repair is being fixed as we speak. Another $1,200 job. 3. No the vehicle has not been inspected by insurance or law enforcement. Only by licensed mechanic shops. 4. There were no warnings, Both times the high pressure fuel pump failed. No prior signs of the issue the first time & the second time the gas smell was so unbearable, that was the indication.

Engine failure due to a problem with the type of engine. Hyundai denied warranty and class action settlement claim, due to exceptional neglect. All oil changes etc were accounted for. the car with no warning, had been driving great, lost all power and left me and my two grandchildren on the side of the road. The Hyundai dealership confirmed that the engine was blown. There were no warnings

Hyundai is having failed engine problems after certain amount of mileage. The engine is burning oils with no leaks anywhere in the engine. You change engine oil after a week we will see the engine light flashing on your dashboard.This is my 2nd vehicle with the same problem. Thank you

While driving on a highway, I heard a rattling sound, which could best be described as tying cans to the car and dragging them along the road. I had never heard this noise before. No safety indicator lights turned on to alert me of any issue. With minutes of first hearing the sound, a very loud pop noise could be heard, followed by immediate engine power failure. I was able to navigate off of the highway, into a more residential area. Upon the vehicle coming to a stop on its own (I was not able to apply the brakes at all), a dark cloud of smoke starting coming from underneath the hood. Seconds later, it burst into flames. I was able to safely exit the vehicle with my dog, but if traffic were any heavier, there would have been no safe way for me to get off the road and to a safe location

I have a used 2015 Hyundai Sonata that I purchased from a Hyundai dealership in December 2021 (due to the chip shortage, I had to purchase used). A few months later In June 2022 I was driving on the freeway and my car felt like it was losing acceleration. I was already planning to exit the next exit to go to my destination and as I was exiting and came to stop at the red light before I could then turn right.. my car started to violently shake. Ultimately, after going to my own car place the following day and them determining that the fuel injectors and the computer were not talking, I had it towed to Hyundai where after another 4 days they also determined it was that problem and they replaced the computer under warranty. Well today I was again on the toll road / freeway and I was in the fast lane, I suddenly felt a strong jolt and my malfunction light came on and it was blinking on the dash, I knew not to drive it based on the light and as I steered to the right shoulder to slow / stop and call AAA I could feel my car just lightly shaking again. My car is now at the same Hyundai dealership where I purchased it and I-??m waiting for diagnostics on the problem. Before this all happened, the first time in 2022 I was having sporadic issues with pressing the start button and there was a bit of a delayed start at times, even after the computer was replaced I-??ve still had hiccups with the start button at times but it-??s been very sporadic and it has never been a starter issue (had my car place already check that). So I-??m now waiting to hear if the computer indeed failed for a second time. They cannot assess my car until Monday or Tuesday at the dealership (today was a Friday, my car was towed there at about 11am today). If the computer did fail again, it lasted about 14,000 miles before it just died again. Quite frustrated at the moment. I already contacted Hyundai corporate and opened a second case today regarding all of this.

Sensors lights would indicate an issue and would disappear sometimes without any reason (mainly Check Engine and Tire Pressure Sensors). Indicators would trigger the opposite direction (indicate right and the left indicator would turn on). Burning more fuel than expected. Primary fuel pump stopped working resulting in car stopping in the middle of the road.

Please refer to prior complaint #11505068 I want to add the fact that this vehicle's engine was replaced on or around Sept 1, 2019. This dealer asked me who replaced the fuel pump, and I responded it was replaced by Rick Case Hyundai where the car was brought to with the seized engine.

I reported a fuel leak while the vehicle is in motion to the dealer on 9/12. They had the vehicle 3 days and could not find the leak although the service manger agreed he smelled fuel when the vehicle was brought in. They released the car without repair.

This is the third time this has happened. The car just starts to beep and stops working wherever it is. Its died on the highway and another busy road during rush hour causing a dangerous backup in which the police needed to be called. The car just beeps and flashes on the dash "Hybrid System Warning! Safety Stop and Do not Drive". Also, "check charging system". The car just stops and basically dies on the road when this light comes. When this happens the steering wheel does not really work and the gas/breaks have limited function. This could cause a major accident on a major highway or even off of a highway. I am quite surprised that there has not been a recall for this serious safety concern.
