2019 Hyundai Sonata Engine Problems

My 2019 Hyundai Sonata has been experiencing excessive oil consumption since I purchased it. The vehicle requires oil to be added approximately every two weeks, which indicates a serious internal engine issue. Recently, the check engine light turned on, and I took the vehicle to a dealership for inspection. I was told that the engine is “operating normally,” despite the ongoing oil consumption problem. I was also informed that the engine would only be replaced under warranty if it fails completely, such as through connecting rod bearing damage. This means I am expected to continue driving a vehicle that may suddenly fail without warning. I drive daily with my children, and I am concerned about the risk of sudden engine failure, loss of power, or engine seizure while driving, which could lead to a serious accident. I believe this is a known issue with these engines, and it represents a significant safety hazard that should be addressed before a catastrophic failure occurs.

I was driving on the interstate when my engine started shutting down on me and I’m glad I had moved to the right lane because someone would’ve hit me from the back because I never had this problem and now the mechanic telling me it jumped timing.

My oil pan cracked. I’ve never had any issues with oil pans until this one. Hyundai will not replace this under warranty.

Hyundai replaced my engine under warranty due to their oil consumption in mid October. About 2 weeks later all warning lights came on and they said need new battery. They put in new battery in November. 15 miles after new battery a burning smell and smoke came from under hood with visible smoke. Took to dealer following day and no smoke. Got car back and next day it’s smoking and burning smell. Got it back to dealership and they had it a while and said no smoke and I got car back. They can’t find a reason and it’s not smoking .About a week later (tonight) burning smell and smoke from under hood at the engine.

The engine is burning oil around 1 quart every 700 miles. I check the car oil level around every 10 days. I have experienced when I didn't check the oil and the low oil engine light would come on in the instrument panel. Hyundai shows no recall for this 2019 Hyundai Sonata Limited edition. I believe that this type of incident occurred back around 2011 with Hyundai's models for that time

Engine is burning oil at an excessive rate. Burning a liter every 1,000 miles and Hyundai refuses to do anything about it.

The contact's mother-in-law owns a 2019 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the vehicle started shuddering. There was no warning light illuminated. Minutes later, the failure reoccurred with the messages "Check Hybrid System” and “Turn Engine Off" being displayed. The contact immediately pulled over and had the vehicle towed to a dealer for assistance. A diagnostic test was performed, and it was determined that there was engine failure and that the engine needed to be replaced. The dealer requested proof of the last two oil changes. The contact obtained a Carfax Report, which showed proof of the oil changes and maintenance records. The manufacturer denied the goodwill request after several months of negotiations. The vehicle remained with the dealer unrepaired. The failure mileage was approximately 32,000.

My oil light came on after driving it about 4700 miles from purchase date. I checked the oil and there was no oil on the dipstick. 200 miles and 2 days later the check engine light came on and put it into limp mode. It was about a half quart low. I was put at risk for having to go slow on a main highway to get back home. I took it to a local Hyundai dealership they did a diagnostic and bearing clearance test for 572.00. They said it passed. Then I did a 1000 mile oil consumption test. They over filled my oil and it passed. The 2nd 1000 mile oil consumption test they did not over fill my oil and it failed. They told me they would submit a PA to Hyundai corporate and as long as the maintenance was done they would most likely replace the engine. He also told me my engine could blow anytime. They never called me back so when I called the dealership they said they denied it needed a new engine. They wanted me to pay another 800 to run a combustion test. I am not paying for anymore testing when they clearly have engine problems with many of their engines. I had warning signs and that’s when I called the dealership I purchased it from and went on this path. I was also told that this was covered under an extension warranty of 120, 000 miles. Only to be told by Hyundai corporate that it is not covered. This is an issue Hyundai is well aware of and they refuse to fix it.

My car has been with Priority Hyundai in Chesapeake Va since September 23rd. They have advised me that I will definitely need a new engine however, Hyundai is requiring them to do 2750.00 worth of work on my engine before they can submit a claim to have my engine replaced. They explained to me that one of the piston rings in my engine needs to be replaced. The service technician reassured me “the failure was nothing that I could have caused”. I have gotten my oil change regularly, and I have paperwork that shows that. The car is five years old. I’ve only had the car for 3 years and I’m the first owner. I have never driven my car long distance. I work from home. The most I do is take my boys to and from school which is at the most 5.1 miles away from my home. The dealer recommended that I call Hyundai my self and start a case. Which I did. Two days later Hyundai Canada called to tell me their decision is final and my case was denied because the warrant is 5 years/60,000 miles I told them the car was over the 60,000 mileages when I bought it and I’m still well within the 5-yr mark. She then says, basically that the piston failure is not included in the extended warranty. However the class action suit states differently. The dealership advised me that their system shows a 99 yr warranty on the engine, which they took that to mean lifetime. They priced me a new engine at 7111.00 in addition to the 2750.00 of engine work they told me I must get done before hyundai would approve me for a new engine. I have been in contact with the lawyers handling the Hyundai/Kia 2.0L and 2.4L Theta II GDI Engine Class Actions. They have added me to the data base and provided me some direction. which have led me to you, the NHTSA.

Problem with the valve cover gasket. Dealer said replaced. Engine oil smell has been entering into the cabin and making me ill. Causing chest pain, headache, dizziness, nausea.

Excessive oil consumption leading to no or low oil levels. Piston ring design flaw allowing oil to leak into combustion chamber, damaging the spark plugs. No warning lights until failure posing a significant crash risk for my family. Engine failure at 134K miles without warning, rings need replaced, per mechanic. I am shocked as I just paid the car off and thought Hyundai was a good brand.

I just had an Oil change twice on this car it burns oil like crazy..mine you only had car for5 months

My vehicle has an oil consumption problem. I put in 5 quarts of oil last week after changing the oil three weeks before this. I am down today December 19, 2025 2 1/2 quarts when I put in 5 quarts last Friday. Hyundai motor Corp. says I have to pay for the $90 oil change to do the oil consumption test then I have to go back 1000 miles later and pay $600 for an oil combustion cleaning and drive it another thousand miles and come back and see the oil level to see if I need an engine. I think this is absolutely a safety hazard and needs to be taken very seriously for all customers that drive a Hyundai that are having these issues.

Burning oil

I have had my car in 7 times for the same issue. Metal shavings in oil and burning excessive amounts of oil between oil changes. This is a very well known issue with 2019 Hyundai Sonata. They have done nothing but add oil and run tests which the car failed. No attempt to fix it or replace it. I have been in contact with Corporate who refused to help. My car has an extended warranty for this specific issue, but they only give me the run around.

I am writing to file a formal complaint against Hyundai Motor America and the Freehold Hyundai dealership located in New Jersey, regarding the ongoing engine oil consumption issues in my Hyundai Sonata. I purchased a 2019 Hyundai Sonata and its now 90,000 miles, I began noticing extreme oil loss, far more than a quart per thousand miles, with no visible leaks, no smoke, and no warning lights. I brought the vehicle to Freehold Hyundai for an evaluation, and they performed an oil consumption test, confirming the issue. They submitted a goodwill repair request to Hyundai Corporate, which was denied solely on the basis that I am the second owner, and the powertrain warranty does not transfer. The dealership offered a $200 PCV valve replacement (a part that costs $6–$20), but even their staff said it likely won’t resolve the issue. Their proposed solution is a full engine replacement costing $8,000 or more, which I cannot afford. I believe this is part of a broader manufacturing defect, and Hyundai should take accountability for the engine failure, especially considering similar complaints from Sonata and Elantra owners nationwide. TSBs (Technical Service Bulletins) have been issued on related issues. A car engine should not fail before 100,000 miles under normal use, regardless of ownership transfer. This issue has been the subject of TSB 20-01-004H, which addresses excessive oil consumption due to piston ring Hyundai’s refusal to provide any real assistance or remedy — and the dismissive conduct by dealership management — has left me feeling discriminated against, frustrated, and financially trapped. I request the BBB’s help in facilitating a fair resolution, either through: A warranty repair or subsidized engine repair Coverage under goodwill or defect-related remedy Reimbursement or alternative assistance Please find all supporting documentation attached, including my Hyundai case number dealer correspondence, and oil test results.

Is anything being done about the known oil consumption issues with the 2019 Sonatas? My daughter bought the car used -- it currently has 70,000 -- but Hyundai won't do anything because she is the second owner and those cars don't get 100,000 protection, they only get 60,000. It just doesn't seem right.

I have had issues with oil consumption in this vehicle for about 2 years. I have taken it to the dealership Vandergriff Hyundai in arlington, tx advising the oil light keeps coming on before oil change is due this was before my warranty had expired on my vehicle. I was told that they could not find anything wrong and a oil change was completed, but no oil consumption test was done. I asked about any recall for knock sensor and i was advised that had already been completed. I have no proof of this being completed. After researching the issue, I discovered that this is a known engine defect covered under Hyundai Technical Service Bulletin 23-EM-008H, which relates to excessive oil consumption. This condition can lead to engine failure, posing a significant safety risk if the engine fails while driving at high speeds or in traffic. This issue is part of an active class-action lawsuit and has affected numerous vehicles with the same engine type. I had my oil changed on April 26th, 2025 and as of June 24, 2025 it was 3 quartz low. this is not normal and it is dangerous.

I am filing a formal safety complaint regarding excessive engine oil consumption in my 2019 Hyundai Sonata. The vehicle, with approximately 90,000 miles, experienced a complete loss of engine oil without any visible leaks. The low oil warning light appeared intermittently and ultimately revealed the oil level had dropped to zero, posing a severe risk of engine seizure and potential accident. This issue appears to be consistent with known problems related to the 2.4L GDI engines used in Hyundai vehicles from this period. Hyundai has issued TSB 20-01-002H, acknowledging excessive oil consumption in certain models. Yet, many affected vehicles, including mine, may fall outside warranty despite being within a reasonable usage period. I am requesting that NHTSA review the extent of this issue and consider whether a formal investigation, recall, or manufacturer enforcement action is appropriate. This engine defect presents a clear safety hazard, especially if failure occurs during highway driving. Thank you for your attention to this matter.

Car has 39,495 miles. First owner of vehicle. Have advised dealership since 2024 that there was a oil issue as i have only went to them for oil changes. I advised that as they can see the car is barely driven and the oil is disappearing. They claimed nothing was wrong and made me pay for a oil change again. Come this year, I advise again there is a issue, they tried to have me pay for a oil change again and I advised something else needs done. They argued I was not the first owner and the car was not in warranty however I bought the car from their lot and I am the original owner. Then they stated I had to pay for another oil change for the oil consumption. Then they claimed they would just do the oil consumption and then to drive 1,000 miles and bring it back. After the oil consumption engine light is on. I drove 1,000 miles, brought it back and the engine failed the test. The dealership changed the engine. 5 days later engine light is on, car is stalling and brake locked up, then car would not start and was smoking under the hood. Car was then towed to the dealership. They claimed nothing is wrong and they reset the code for the engine light to go away. They stated evap code was on but was not persistent so it's fine. Few days later engine light comes on again and once the car has been running, you shut it off go to start it again it won't start unless you have it sit for a while. I Take it back to the dealership they point next to the engine saying a purge valve, but the wants money for a diagnostic. They do the diagnostic and still provide maybes, as they claim the filler neck is rusted and corrosion. I take the car to another place who states the filler neck is fine.
