Purchased a used Hyundai Sonata in June 2020 when it had almost 57,000 miles on it. Got the car regularly serviced and provided receipts to Hyundai on the national level as well as the local dealership. Received the following claim number - Hyundai Motor America Case#: [XXX]. [XXX]is with the Dealership in Dallas Texas and they car is with his dealership. Have also been dealing with[XXX] at Clay Cooley Hyundai Mesquite [XXX]. The engine does not work and needs to be replaced. Hyundai should be responsible for replacing the engine. The car has only around 76,000 miles on it. Hyundai Mesquite is threating to tow the car and possibly have it junked if it is not picked up. I cannot afford to pick up a car that does not operate.

I purchased my vehicle in November 2022 from Honda Dealership. It was making a noise and -??drove funny-?? I asked them about it and I was reassured the vehicle was in 100% working condition and they were not allowed to sell -??bad cars-??. So, I let it go. Since I purchased the car I have maintained regular oil changes and service on it-?" I just bought the car! I have been getting oil changes a lot sooner than I should, and every-time I take it to the shop they say it-??s bone dry. Current: my car recently stopped working without any warning at all. I got a diagnosis from the mechanic that my engine failed due to pistons and rods. I did some research and found my car listed for a recall for campaign 953. And I am not the only sonata owner experiencing this problem.

Problem began Dec. 2021. Has occurred on 16 occasions since then. Warning light "Check Hybrid System; Turn off Engine" comes on while driving. The car then shuts off the engine and there is a 100% loss of motive power. Sometimes is associated with very rough braking with the car "knocking'." On 3 occasions there has been partial/near complete loss of braking power. All incidents have occurred while under power, so far all while under 45 mph. No accidents yet. Two near collisions from the rear. Hyundai was notified of the problem Dec. 2021/Jan. 2022. After a month of testing they stated the car needed a new plug-in hybrid battery. One was not available and due to "supply chain issues" is still not available 15 months later. Dealership provided a loaner vehicle Jan to Sept. 2022. They requested their car back and Hyundai initially agreed to cover the cost of a rental car. I rented a car for 6 weeks in Sept.-Oct. 2022 at which point a new case manager informed me that Hyundai would not pay for a rental vehicle any longer (note: they did reimburse me the cost of those 6 weeks rental). Hyundai is well aware of the safety issues involved in driving this vehicle. However, they have chosen to ignore them. Their attorney, in a letter to the Ohio Attorney General's Office, blamed the lack of a plug in hybrid battery on supply chain issues (letter was Nov. 2022, at which time the battery was supposed to be available March 2023) and only stated that my vehicle was "drivable." Another warning message "High System Temperature; Switching to Hybrid Mode" has been occurring for a couple of years periodically. Since October 2022, the malfunction indicator lamp is always on and 99% of the time the "Check Hybrid System!" warning light also comes on after about a minute after starting the vehicle. On 3 other occasions the vehicle has entered into "limp home mode" instead of complete shutdown.

I was driving southbound on I429 approaching the Vineland Wintergarden (FL)exit. approximately.75 miles from exit, a bit of an uphill. I heard a ticking noise, then suddenly the car went silent. The screen lit up with every sensor flashing. It took me a few seconds to realize I was in potentially deadly trouble. The car began slowing from 70 MPH to maybe 25MPH as I crested the last hill. To add complications, that stretch is under construction and does not have any shoulder. I could see a wall of cars streaming ever closer in my rear view mirror. I believe my hazzard lights probably saved me from a crash before gliding the last 1/4 mile to the exit where I was able to finally pull over to safety.

On February 11, 2022, I took my car to the dealership because my oil light came on. I was told I had no oil in the engine. So they said to get an oil change and that would take care of the problem. Nope. It has not taken care of the problem. My car burns oil. I have taken it to 2 different Hyundai shops. One just kept changing the oil and never submit the paperwork until I got really upset about bringing my car back a month after having the oil change. No help. I have called Hyundai customer service no help at all. In January 2023 I went to start my car and it started jerking and shaking and spitting out oil threw the tailpipe. The car would not move. My garage door was covered with oil. I had it towed to another Hyundai dealership they kept the car for a week and told me that it needed a new spark. New wires because it was covered in oil. I'm out of $3000 including all the oil changes and the work that was done. Oh yeah, I was told to bring the car back after 1000 miles. I brought it back in March 2023. They started the oil consumption test. I was told to bring it back on that Thursday the 5th. I took my car back and the dealership would not accept my vehicle. Wouldn't let me leave it for my service guy nothing. I called the next day for my service guy and they said he didn't come in today. I even filed with the BBB Auto Line. I found that information in my 2017 owners handbook supplement did not help closed my case. They didn't even call or asked me any questions. No help. Stuck with a car I have no confidence in. I don't know if the engine is going to blow because the oil gets low or if it's going to sketch on fire because theirs no oil in it.

Hello, I would like to file a complaint my name is [XXX] I am having a translator help me to write this. I was taken advantage of by a bad car dealership who sold me a dangerous car that smokes leaked oil does not stop and locks up they said the car was safe they also did not explain the contract to me. They want me to drive unsafe vehicle 1000 miles. They won-??t give me a loaner car. They won-??t give me my money back or a replace my car I feel unsafe and I don-??t want to do business with them ever again. I want my money back. They took advantage of me because I didn-??t know any better. Translators notes : regarding purchase of vehicle: He purchased a used car, 2017 Hyundai Sonata/ at McGrath City Hyunda. He does not know English The dealership took advantage of him he doesn-??t speak English and is a first time car buyer, they made him sign a contract selling him an unsafe vehicle, without explaining what arbitration is the car is unsafe.. He had immediate problems with the oil and smoke coming out of the car within the first week and went back to have an oil change they charged him money. The following week the same issue occurred with smoking and stalling of the car. He brought the car in for service and they tried to charge him almost $500 for a new gasket. I told them this is not right and I would report them to consumer affairs they said they would repair it 10 days later the same issue occurred and he brought it in again they put oil in the car and he had problems again. When he brought it back they said they need to keep the car to have it serviced and they would not provide him a loaner car. He is renting a car and spending a lot of money and he is making payment on the loan for the car. The dealership is forcing him to drive an unsafe car 1000 miles in order to have an engine replaced not care about his safety. They told him he has to drive the car for 1000 miles in order to have a warranty take effect he is scared to drive it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (

Excessive oil consumption and Engine locked while driving on the highway. I couldn-??t drive my car and it was towed to a mechanic. The cost for a new engine and labor is $7970.

- Grand Prairie , TX, USA

The engine is consuming (burning) the engine oil at a excessive rate. Engine oil has to be added almost every 1000 miles. Talked to multiple mechanics and learnt that it is a common problem with Hyundai. Constantly checking the oil level and topping off is not what we expected when I bought the car.

UNKNOWN I-??ve had to replace the knock sensor twice in my vehicle in less than 2 months, my paint on my car is also peeling off really bad.

- York, SC, USA

bought the car used with 60K miles. Learned quickly it was consuming 1 qt of oil per month. I checked with Hyundai Corporate Customer Care and my local dealership. Dealership said needed to burn 1qt per 1000 miles before they would submit anything to corporate for possible warrantee issue. Monitored consumption. Now up to about 2 qts per month. Took it to the dealership and they said now beyond warranty mileage. They performed a computer update recall. Now the computer detects something going on the engine and forcing car into Limp Mode. Been on the phone with Corporate Customer Care and the dealership. They will do nothing. Customer care says to go to dealership. Dealership says to call Customer Care. There doesn't seem to be a way to talk to any decision makers to appeal for common sense and discretion instead of 100% by the book policy protocal. The dealership said the computer update recall cannot be reversed. So now I have a vehicle with an engine problem and in Limp Mode and Hyundai will do nothing. So discusted with Hyundai quality and customer service. I will never by a Hyundai again.

Car has been consuming insane amount of oil.The oil warning light hardly ever comes on and when it does it is always in between the oil changes. It doesn't even make it to the next scheduled oil change before the light finally comes on. When I check it when the light is on it is bone dry. Because of this I have started checking it every couple hundred or miles or so and every time it's bone dry and I have to add at least two quarts of oil, if not a total of five courts. I informed the dealership about this last year they performed the oil pressure check and told me that it was fine. I insisted that oil must be leaking somewhere, they checked and said that there was no oil leak. Last week my car started sputtering, and then the engine light came on. It did this in the past and it needed a new starter. They replaced that but this time, they check the engine and they say that I need a new engine. I told them I'm not surprised because every time I check there's never any oil in there in the warning light never goes off. Yet they have told me in the past that it does not have a problem? I am currently waiting to see if Hyundai will honor their warranty. This is a hazard if they cannot tell if there is a faulty sensor or oil leak but the car continuously is consuming oil to the point that it's dry and the owner is not notified. I have kept up the oil changes and this is all happening in between the schedule changes. This can cause fire, vehicle disablement in the middle of driving and other safety issues. If you look at other reports, this is common across the Sonatas yet Hyundai has not issued a recall regarding the oil consumption.
