In early June 2024 while driving 65 MPH vehicle started shaking, engine and oil light came on, losing power, noisy and only would go 50 MPH max. When destination reached, checked oil level (was low) added oil.Took the vehicle to auto repair shop. Review showed a misfire in cylinder #2 with plug oil fouled and recommended new engine. The car was taken to the Hyundai dealer who performed various diag. procedures via communicating with their Techline who ended up rejecting the request to replace the engine due to the milage (136K) being out of warranty. They would replace engine if the connecting rod bearings had wear or damage. Hyundai national consumer affairs contact given for the case refuses to listen to any information given and only states vehicle is out of warranty. Hyundai knows this engine has manufacturing issues causing them to wear out prematurely including excessive oil consumption. They should extend the warranty to at least 150K. Afraid to drive car as engine may suddenly stop or catch fire causing accident/injury to occupants. Please help!

Vehicle is burning oil. Have been using fully synthetic oil at regular 3000 miles. And have been increasing -??burned-?? more oil before each oil change. Valvoline Instant Oil Change is the shop I-??ve been going to for my oil serviced maintenance. My last visit I had 1 quart of oil left in my engine.

- Carlsbad, NM, USA

Engine is burning a lot of oil. Having to get frequent oil changes due to the engine burning oil.

- Milwaukee , WI, USA

The car is burning through oil at an excecated rate. This is a well-known issue with this make and model. The dealer said they fixed the problem, and they did not. This engine needs to be replaced. It was inspected by a mechanic not affiliated with Hyundai. Hyundai has refused to replace the engine. This should be covered by the 15 year/ 150,00 engine warranty. This engine could seize up at any time. It is a hazard to be driving. The driver is an 80-year woman. She needs help.

Bought a car. In couple days check engine light came on, it was blinking and car was put on limp mode, rpm between 1800-2000, speed 60-62 mph. Went to dealership they did full diagnostics, told that they are going to submit to Hyundai to replace engine at their cost. Hyundai came back that they want to replace knock sensor and then see what-??s gonna happen. I replaced and was told that i have to pay even though there is a recall on Knock sensors. They replaced the sensor which was over 600$. And the problem came back in less than 36 hours. Now the vehichle is back again at the dealership and they gonna do diagnostics again. Which is ~200$. I need to help this resolved as i-??m only being ripped off with no solution. The vin says it doesn-??t have any recalls, but vehichle is experiencing exactly what-??s on recall. The vehicle has been in the shops for a month now. Thank you

My engine burns oil like crazy. At least 1 qt every 1,000 miles or less. Took to dealership and was given a hard time about it having an issue. Now my power steering light keeps randomly coming on. I'll feel the steering start to get hard to steer. Thought I needed belts so I replaced both serpentine & water pump belt but it still happens. When my power steering light comes on and steering wheel locks up, I have to put the car in park & rev the engine to get the light to turn off. Mechanics said all pulleys are in good shape so not sure what's doing it. My lights also start to flicker when power steering light comes on. I have a new altenator and battery so it's not caused from that. I have no idea what's causing it but it's extremely dangerous!!

The contact owns a 2017 Hyundai Sonata. The contact stated that the check engine warning light was illuminated. Additionally, the contact stated that the vehicle made an abnormally loud sound while idling. The contact stated that while accelerating from a complete stop, the vehicle was significantly sluggish. The vehicle was taken to an independent mechanic, where the camshaft position sensor was replaced several times; however, the failure persisted. The mechanic diagnosed the vehicle with internal engine failure. The vehicle was not repaired. The vehicle was taken to the dealer but was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 83,000.

Engine oil misfire also noted as a recall on the 2016 model and repeatedly mentioned on line as an error in the 2017 model now reaching simlar mileages. Dealer is refusing to acknowledge it as a problem and says the engine light si not recording the error and yet an outside analysis says its error 0302!! the same as the 2016 recall notice. The 2017's should be recalled for the same fix

They car has high oil consumption. It only has 70,000 miles on it. It should not use a quart of oil or more every 1000 miles. Need to be put on a recall. Engine just like people have said about 115000 miles or more your engine will possibly blow, or sieze up. No car should have that much oil consumption. I change or have my oil change every 3000 miles or close.

- Muskogee, OK, USA

The vehicle itself shakes when accelerating and will start to fail once 60mph is hit. It will also cut out when left turns are made...I have met 4 people with the exact same issues who received recalls but I am not sure why my car is not included. I was almost rear ended on the highway by a semi with my pregnant wife and 4 year old son in the car because of the engine failure.

To whom it may concern, I would like to inform you that I have been experiencing engine power loss and oil evaporation from my Sonata. In fact, I took the vehicle for an oil change in April 26, 2024 and by August 1, 2024, my car was not accelarating and the dashboard was completely illuminated with the engine, air bags and suspension lights. Upon inspection of engine oil dipstick, I was made aware that my oil was missing (evaporated) without any visual undercarriage drips. Therefore, I added 4 qts of synthetic oil to my car recently replaced oil and the car continued without power. Upon connecting a vehicle code reader, it was reported that a spark plug was malfunctioning and I continue with its replacement. To date the vehicle continues to have engine loss of power episodes. Can someone please help as I do not want to die in this vehicle due to a manufacturer's unannounced/undisclosed engine issue. Thank you for your time and consideration.

While driving, car started to lose power. Warning lights started flashing to turn off vehicle to recharge battery. Car lost all power. Car was towed to dealership. Dealer started diagnostic testing, and first thing that was noted is that all oil had drained from car and that crank shaft may now be damaged. Prior to incident, no warning lights came on for service, engine or oil lamp. Dealer and internet searched confirm this has been happening to this model recently.

I was driving the vehicle and it of no where the hybrid warming triangle comes up and I had to pull over. The car went in creep mode and then rpm and sped was capped.

Me along with thousands of others are experiencing the -??excessive oil consumption-?? issue. Hyundai is doing nothing except making us pay tons of money for testing when they already know what the issue is and is refusing to do anything. Enough is enough. I can-??t afford a new car nor should I be forced into buying one. The dealerships have been instructed by Hyundai USA not to admit negligence or helping g the car owners.

This is the seventh occurrence of complete loss of power while driving on the interstate. The hybrid system warning activated, followed by the engine shutting down, and all dashboard lights illuminated with alerts indicating "Shut Off Engine/HEV." An 18 wheeler was pulling out from the shoulder as I was losing power and barely missed getting crushed. The former problems have all been at interstate speeds with similar accident avoided. The service history clearly demonstrates that Hyundai has repeatedly attempted to address this issue by replacing numerous critical components, including the engine, transmission, knock sensor, battery (three times), integrated brake actuation system, and smart cruise control, among others. Despite these extensive repairs, the problem persists. On this latest occasion, less than 4,000 miles and four months since the last major incident, the dealership has proposed replacing the intake manifold, EGR valve, HSG belt, and spark plugs. The belt was changed less than 20K miles ago. and I believe the spark plugs were as well. Each time my vehicle experiences this issue, it is out of commission for weeks or even months at a time, causing significant inconvenience and raising serious safety concerns. I no longer trust this vehicle and I don't believe the many recalls have successfully addressed the root cause of issues with the 2017 Hybrids.

I had the engine replaced in Feb of 2024 which was covered by the engine replacement recall. In May of 2024 I started having issues with my check engine light flashing on then off. The engine will lose power briefly during this time and the engine shakes. It feels like you are going to lose control of the vehicle when this happens. This has happened approximately 3 times at freeway speeds and a total of approximately 15 times total. I have taken it to the dealership 3 times for this issue. They made us pay for spark plugs that were fine when the engine was replaced (3800 miles was driven between the engine replacement and this issue starting). The dealership has now had the vehicle since the middle of May said they can-??t recreate the problem but are saying it is a fuel pump. This was also fine when the checked it when the engine was replaced.

Apparently there has been a leak in the engine and was not retaining any oil. We-??ve tried to fixed it but it wasn-??t fixed properly. My safety and others were at risk by the car shutting down at any moment. I have not taken it to the dealer yet. I am willing to do an inspection at a dealership for a better understanding on the issue.Check engine light came on about a month ago and I kept trying to fix it but check engine light is still there.
