The issue is with the hybrid system, which malfunctioned and apparently ruined the rest of the car. The damaged components are adding up to over 75% of the car's value. The vehicle slowed and stopped suddenly on a busy road when the issue started. Currently, it has been inspected by two different shops and they have both given me the same diagnosis.

We had taken out 2015 Hyundai Sonata to the repair shop because the check engine light came on. The repair shop said it gave the error for low oil, but the oil in the system was not low and we were barely past the oil change mileage. We had the oil changed and picked the car up. The next day, the car lost all power and locked up completely while going about 45 mph down the highway. We had to push the car off the highway. Car was towed to same repair shop and we were informed the motor was blown. We called Hyundai but they offered no assistance since we were past 100,000 miles. The engine blew at 114,000 miles.

Had it for 3 months when it did the same thing to her again. Had it towed again to same dealership where they are telling me it needs a new engine.

The contact owns a 2015 Hyundai Sonata. The contact stated that after having her vehicle serviced under NHTSA Campaign Number: 21V749000 (Exterior Lighting, Electrical System) the exterior and interior lights would turn off while driving at various speeds, with the check engine and oil warning lights illuminated. The contact also stated that upon using the turn signals, the headlights would intermittently turn off; however, the headlights would turn on upon toggling the light switch. The contact had initially taken the vehicle back to the dealer where she was given a diagnostic fee to determine the cause of the failure. The vehicle was then taken to an independent mechanic where she was informed that the E-CVVT actuator was defective. In addition, the contact also stated that the vehicle would hesitate upon depression of the accelerator pedal or lunge forward upon depression of the brake pedal. The independent mechanic linked the failure to the E-CVVT actuator. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 80,000.

My wife is concerned for her safety and our three children. On start up and driving engine feels like it's shutting off and turning back on. I was told by a local mechanic that there are several issues that Hyundai knows about and basically aren't fixing. Engine light keeps coming on and off with a different code everytime. Issue has been going on for about a year replaced spark plugs and had decarbonization process done to no avail.

Engine failure while driving on freeway. Lost control unable to accelerate, almost got hit by semi due to inability to move out of way swiftly. All engine oil came out due to rod bearing punching hole in engine block and car started smoking, fire department said I had maybe 2 minutes before my car would-??ve been engulfed in flames.

The engine constantly needs oil added. There is no oil leakage showing on the ground. I have to add oil ever week. The engine also knocks going at slow speeds up hill and has started knocking when started if you turn it off and restart it it will run ok. The dealer says the engine has to fail completely before the recall will be completed. So I have to drive it until it fails somewhere on the highway and could easily cause a serious accident.

2 recalls were found on my car and a service campaign. After taking my car to a couple auto shops, within 2 years my car has had the same repair issue involving P010 & P011 codes. After researching and finding there was a service campaign and 2 recalls, I decided to take my car to the dealership due to address the recalls. I took my car in on 8/1 and had a full inspection done on my car. Outside of the normal wear & tear, I was advised that the ECVVT cap was installed incorrectly, that it was leaking oil. I was told that cleaning the oil & reinstalling the cap would correct the problem, it didn-??t and I-??m out of additional money ($562) and the problem is reoccurring. I-??ve called several times recently, as well as one of my mechanics, hadn-??t received a return call not until I filed a BBB complaint. It seems they are not honoring or even considering the service campaign (ECVVT Seating issue) and it is my belief, will continue to send me in circles to pay more money. A full inspection was done on my car, wasn-??t nothing major but my engine light came back on in route home. I called the advisor and he couldn-??t give me a definitive response as to when I could bring my car back & get it checked again. I wanted another appointment time so that I wouldn-??t be inconvenienced by sitting at the dealership all day until they decided to check or get to my car again. It took me almost a month to get the 8/1/22 appointment. The staff I spoke with has tried to convince me that the issue with my car has nothing to do with the recalls or the ECVVT service campaign, I disagree especially experiencing the repeated P010 & P011 codes. One of the recalls also was for the ECM.

Engine problem. Massive oil consumption. We bought our 2015 Sonata new and have taken it for service and maintenance at the dealership. I have all records from dealership maintenance. Have been told that its just normal for that engine and to keep adding oil. Now I have to check and add oil weekly or it will be empty. Started having issues in 2017. Hyundai knows there is a problem with the engine. I dont know who to talk to or what I can do.

It happened with me twice when I noticed that after about 1800 miles after my car-??s oil change, the oil light comes up when there-??s a turn or a speed bump. After checking the dipstick, I noticed that there was no oil in the engine. I got it checked for some possible leaks in the car but there were none. This narrowed it down to the cause that the car is burning oil too quickly and that it could also lead to to engine seizure if on a long drive. I also did some research on the same and found that I wasn-??t the only one and that there still hasn-??t been a recall on the same. I believe it is a safety issue if the engine malfunctions while driving, be it long range or a short one.

The engine stalls out randomly. This is the third time it's done it. The first time was while I was exiting the freeway on March of 2021, which I thought was a fluke. The second time was July 19th and the third time was July 30th. There were NO warning lights or messages. Took it to the dealer and they said that everything came back fine with the engine. They confirmed that the RPMs were too high when it was in a parked position and the engine was on when they first took it in. They suggested I replace the starter. I'm going to a different mechanic for a second opinion. The car was in motion with my foot on the gas pedal when it started to stall. There is no way that it is from a starter.

Engine burns 2 quarts of oil a week. Took it in for oil consumption tests and Hyundai figures out ways to not replace these faulty GDI Engines. Also car has a strong gas smell inside car. Maybe gas leaking. Airbag warning light has been on for years. Took it to the dealer in the past they said it's ok(Hub Hyundai Katy TX) but I don't feel confident.

Multiple times, when the car start up and is put in to reverse, there is no throttle response. Simultaneously, it can not be put into the manual gear select mode and the car lurches into second gear.

Driving at 55 and the engine blew. No warning, no check engine light, no sign of anything wrong. Power steering loss, limo mode activation. Almost rear ended during catastrophic failure. 111,000 miles
- Vero Beach , FL, USA
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.
