The vehicle is slow to accelerate and as its accelerating it often will jerk or hesitate roughly. There have also been times when accelerating, such as getting on a highway, that the whole (what I assume to be) throttle system will almost stop and it feels like the car is just going to stop right there on the highway. It's very dangerous as cars behind me are also accelerating and not expecting my vehicle to just stop. The vehicle is available for inspection. There are no warning lights, messages, or symptoms prior to the issue. It has not been inspected by anyone yet.

My ABS lights came on and then minutes later my check engine light kept blinking while my car kept stalling or not let me accelerate in the middle of traffic. It-€™s like the engine dies but the car is on. It only stalls for a second then accelerates then stalls again and accelerates. Almost caused an accident. Seems that this is a problem for a lot of these models. It-€™s just crazy how it all happened back to back. My car has been running fine otherwise till that happened.

Was driving with cruise control on and driving close to 70mph and the RPMs shot up passed 5 then the car jerked and my speed had went from 70 down to 50 and 40 the cruise controle turned off on its own and the car lost power but was still on but it just wouldn't drive passed 2 rpms and the check engine light was flashing so I turned around and headed the opposite direction so I could get the car off the road then it made this loud noise sounded like throwing metal inside a metal bladed fan and then the car shut off and hasn't started since. The car did not over heat or have any smoke coming from it.

Major oil consumption going on for years. Took in to dealer two years ago, they know there is a problem. They told me I could spend thousands of dollars to tear it apart to find out what is going on, and also told me to call corporate. I got no where with either, even though they recalled the engine in other Sonata cars, just not our ECO model. Slowly started having throttle issues at 4 to 5 year mark. Informed dealer service center that it wasn't moving like it should when gas was pressed. Now, the car is having major problems with acceleration. Barely would go in reverse, drove 1.5 blocks, speed not matching to throttle, press on gas, barely moving from a stop, going really slow, had to turn around and take back home. Our problem with the car is the same that others are complaining about. The car is not safe for a 7 year old car that started having problems at the 4 to 5 year mark.

While driving in city traffic, 45 mph zone, my car suddenly lost power, engine RPMs dropped, engine off, power steering impaired, I had to drift into turnout and assess. Car restarted, and I could drive, but RPMs would not exceed 1700, car wouldn't shift gears, speed would not exceed about 15 mph. No engine warning lights, no oil pressure indicator, no excess heat. I found I could drive at low rpms and manually shift gears to increase speed. I got the car to the local Hyundai dealer (Taylor hyundai, Augusta GA) and it has been there 8 weeks. They are telling me the engine has failed because I failed to change the oil for 14 months. They said my oil pan was empty. They asked me for maintenance records and said they were inadequate, and the engine needs to be replaced, may cost $6000 or more, warranty invalid. The car has 56,000 miles. Safety was put at risk due to sudden loss of power in busy traffic. Driving the disabled vehicle was risky to surrounding traffic, as the car could not maneuver quickly. I have read about similar failures with Hyundai Sonata vehicles, and a class action suit settled for 2011 to 2014 model vehicles. My car is still in the shop, unrepaired. I had to buy another used car in the meantime.

This is a follow-up to former Complaint #11450586 (05-Feb-2022) and confirms that both my local Hyundai Dealer -and- Hyundai Corporation (USA) are aware of this diagnosable- and fixable problem-€"but they fail to issue a recall. In fact, a Service Advisor at my dealer expressly vocalized that 1) he himself [excluding his colleagues] has seen at least -2- of the same incident recently; and that 2) Hyundai Corporation (USA) issued a -€œ(service) bulletin-€ about the problem. PROBLEM: The vehicle: 1) has a high idle; 2) shows a solid-illuminated CEL/emissions light; 3) severely resists braking-€"my vehicle would even slide through stop signs; 4) fails to -€œpick up-€ normally; and 5) drives unsteadily. This is at minimum and is my experience from both last week and from the original report on 05-Feb-2022. As explained to me today (28-Mar-2022) by my Service Advisor, there is a known fault with a component within the engine (Powertrain). Specifically, there is a tube that is-€"as I understand-€"meant to be FREE of fluids. However, and per the Bulletin, the tube becomes full or over-filled with oil from the engine (Powertrain). Further, the Advisor suspects that changes in temperatures (e.g., such as the teens back in Feb 2022) causes that oil/fluid to expand and contract, causing (further) damage. This issue must be remedied by Hyundai Corporation (USA) immediately because it is a *SAFETY RISK.* My Dealership emphasized severely how unsafe it would be to drive the vehicle off their premises without a repair. I-€™m fortunate because I-€™m the original owner and thus am covered by the 10 yr/100,000 mi Powertrain warranty. PLEASE SAVE LIVES FROM THESE -€˜FLYING-€™, UNCONTROLLABLE CARS BY MANDATING A RECALL. * will provide Dealer-€™s documentation once vehicle is repaired. I was advised to wait 2-8 wks for parts and repair.**

My car has been stalling, hesitating and sometimes I feel the engine shake when using the gas. I brought my car to the dealer to have the most recent recall fixed and asked them to diagnosed what else was going on with my car. They told me the stalling was just due to the recall. However, the very next day my car was acting up again. Additionally, the car at times will accelerate when I am not pressing on the gas. I don't think I need to go into detail about how my safety and the safety of others is compromised when you have a car that accelerates on its own. Lastly, there is no check engine light on. This has been ongoing for several weeks.

Car has been consuming an excessive amount of oil (1-2 quarts per week). While driving down the highway the oil pressure light came on and the engine started clicking and knocking. The engine died and all the dash lights came on. The car was coasted to the side of the road and towed into a local mechanic. The engine had seized and presumably dumped all the oil at the time of the engine failure since the engine had no oil when diagnostic was run. Car was taken to Hyundai dealership and is awaiting diagnostic and repair.

The vehicle's transmission seems to be slipping or something. As you begin to come to a stop, the vehicle bogs down and you can not accelerate. There is a long hesitation and then suddenly it kicks in and jars the car. This happens on a daily basis. The vehicle is also burning through oil at an unprecedented rate.

This 2015 Hyundai Sonata LTD ([XXX]) falsely indicates CEL/emissions light. When the vehicle is started and the temperature is appx. 20 or lower, the indicator immediately displays. It is solid and does not blink. This happened on -3- days this week, over approximately 7 of -9- total ignitions in that time. Various forums show the same issue. Hyundai must recall this because it is either a false warning or else is a component within their control with which they failed to manufacture safely (thus contributing to the problem(s) and CEL). INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Sonata started having problems with less than 50,000 total miles. The accelerator is flawed and the vehicle cannot keep speed when traveling uphill or get to speed efficiently. The vehicle jerks for a few seconds when pressing the gas and the engine revs but the vehicle does not accelerate like it should. This has almost caused me to have accidents multiple times when pulling out into traffic. The check engine light came on when this started occurring and has been on ever since. I'm having the hyundai dealership take a look at the vehicle and see if there is anything that can be done.

My car keeps stalling while I am driving and sometimes when I turn to a street and is consuming motor oil with in a mile or less. It has been inspected by a Hyundai dealership and no leaks were found, consumption test has been done and they said that they can-€™t do nothing about it because I am the second owner. Hyundai needs to extend warranties to second owners as well if the car was bought through a certified dealership. I trusted their brand and dealership. I have been going back and forth with the dealership. My car is in the Napoleon Hyundai dealership in Carmel, Indiana. I have a video explaining the situation and showing my engine measuring stick with very low oil.

Had an Engine recall for the 2015 recall, was told that Transmission was the reason for the Engine failure, but the dealership would not fix the Transmission. Shortly following the replacement of the Engine, the problems that reside in the transmission are now costly up to $3000 or more for this issue. After extensive research found that the 2015 sonata has had plenty of issues with its Transmission. Responsibility for the Faulty Transmission causing engine to completely shut down and not work (happened while on highway) should fall on the dealership.

My Sonata Eco is a 2015 model with less than 46,000 miles. I take it for scheduled maintenance at least twice every year since I purchased it. The vehicle was experiencing stuttering, vibrations and lack of acceleration, most frequently when turning, moving uphill or early after startup. The stuttering would vary in it's intensity, from barely noticeable to strong enough to shake passengers. Sometimes when performing a turn, my car would not be able to accelerate, leaving me in the path of oncoming traffic until it would start working again. This would also occur when travelling uphill. No warning lights or other messages were given by the car. After taking it to the Hyundai dealership they informed me that my transmission was faulty and would require a full replacement. They specifically mentioned it was a mechanical issue with the dual clutch not engaging properly. All electronic/software in the vehicle was confirmed by the dealership to be up-to-date so this was purely a mechanical issue.

2015 sonata intermittent problem which involves loss of acceleration when taking off from a stop. One has the accelerator to the floor and vehicle goes to 10 to 12 miles/hour until it gets to about the 3rd or 4th gear. This car has done this 5-6 times since the 20th of May. Took car to dealer; they hooked it up to the computer and got no codes, so I was told it was OK. I told them the car was unsafe to drive. This car has a duel-clutch automatic transmission which I believe has a major problem. Not sure what I can do about it. It has 71,000 miles and should be under warranty.
