2019 HYUNDAI SONATA Engine Problems

Steering wheel panel glued/tampered (Safety Hazard) Motor/Pump assembly broken. Recall couldn't be done due to tampered parts.

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.

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.

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

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.

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.

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...

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.

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...

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

Burning oil

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.

Burning excess oil

The contact owns a 2019 Hyundai Sonata. The contact stated that while driving at various speeds, there was a knocking sound coming from under the hood. The contact stated that the engine was consuming an excessive amount of engine oil. In addition, while attempting to drive, the vehicle failed to exceed 5 MPH. The check engine warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed with a blown piston and cylinder #2 failure. The vehicle was repaired; however, the failure reoccurred. The contact stated that while stopped at a stop sign, there was black smoke coming from under the hood, with an abnormal sound coming from the vehicle. The vehicle was taken to another local independent mechanic, where it was diagnosed, and determined that the catalytic converter needed to be replaced. The manufacturer was not made aware of the failure. The failure mileage...

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

I took my car to the garage after purchase around 75,000 miles due to rattling noise 8n the front and the amount of oil that my car was requiring in between oil changes, did the oil consumption test it came back on the higher range but Hyundai offered no resolution

Burning oil four quarts in between normal oil changes

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...

Car drinks oil and doesn’t make it to the next oil change.

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...

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.

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...

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...

Rod clearance test

Bought 2019 at Priority Hyundai in Chesapeake va in JUNE of 2022. Noticed that car stay burning oil in march of 2025. Took 2 oil consumption test at dealership and failed both. Hyundai knows these consume oil even with proper maintenance but will do nothing to try to make it right. Basically got turned down and service advisor ADVISED me to buy a new vehicle. The car only has 75,330 miles on it

The car stalled and came to a stop on the highway which was very dangerous. Took it to mechanic and they found the cylinder 3 and 4 misfire and suggested we take it to hyundai dealer for repair. Took it to hyundai dealer and they did a compression test and found only 40% compression in cylinder 4. All cylinders should be around 180%. Engine needs to be replaced and hyundai refuses to help.

I purchased a 2019 Hyundai Sonata SE in December 2024. Within one month, the vehicle consumed 3.5 quarts of oil out of a 5-quart capacity. 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 am reporting this defect so that the NHTSA can track the scope of the problem and determine whether a recall should be issued.

I have had issues with oil consumption in this vehicle for about 4 years. I started getting a "Knock Sensor" code. I replaced the knock sensor and still had problems. Hyundai had a recall and they reprogrammed my computer board. A year later I was having the same issues. My car started stalling out. Took back to the dealership they said my engine had sludge and now they're saying that there is a hole in my engine. Hyundai is saying that I don't qualify for assistance.

My Hyundai is having oil consumption issues, Hyundai isn't stepping up and won't pay for my consumption test saying it's out of warranty, it's a 2019 with only 69895 miles on it. We are the second owner and there's been no maintenance done on this car for the year that we've owned it. We have all the oil change records and although we didn't start until January to regularly record the oil we were needing to put in we only get about 600 miles before we need to had 3/4 to 1 full quart. I know this is an issue that's been happening to numerous Hyundai owners and I'm reaching out as I feel something more needs to be done. I have a 2013 Sonata that had a recall on it and I got a full engine replacement on that at 135,000 miles. Is NHTSA looking at recognizing this as...

Car started consuming large amount of oil at 80,000 miles, no leaks or drips under the car or on any of the under panels. I am adding a quart of oil every 1000 miles.

The part in question is the oil pan. An oil leak was identified at the place where I get my oil changed. The service center at the dealership informed me that there was a crack in the oil pan due to overtightening of the drain plug. I am not sure how they made that connection. The risk of this oil leak could lead to engine failure if oil levels drop below a certain level. There were no warning lights or messages from the car about the oil leak.

What component or system failed or malfunctioned, and is it available for inspection upon request? Since april 2025 i’ve been having low oil readings in my vehicle despite regular oil changes I took it into the dealer since my vehicle was still under warranty, which they stated only one part was under warranty. I had to pay $800 after this was replaced. I started having engine light come on. This engine light when I paid a diagnostic fee I learned that the cylinder three was misfiring. It was suggested that I have an oil change and get the oil level checked again within a week. This was done and it was determined that it was burning too much oil. I submitted this to the insurance and was told that this was not covered that there must be another reason why this was not working the way it should. 3 weeks...

I started the car and smoke came from the engine compartment I didnt think anything of it but the smoke keep getting worse . So I pulled over and open the hood to find fire come from on top of the Engine the flames got higher so I asked an local restaurant for an fire extinguisher I put it but know these cars this could of been an big problem if I had parked in the garage or park next to other cars or even if I keep driving . It would of not been good! By this time the Shelby Twp. fire dept showed up and sprayed more water on it.

Failed Component: Engine - Burnt Valve/ Snapped Piston/ Piston Scrapping Internally; available for inspection - Risk of safety: Car sputters/jerks upon acceleration, takes a long time to gain speed, STALLS when slowing or stopping, may or not start after stalling, violently shakes while driving - Problem has been confirmed by Hyundai dealer/repair - Component has not been inspected by the manufacturer, police, insurance representative; only Hyundai repair - Warning lamp, messages, and symptom PRIOR to failure, NO, after the failure, YES; check engine light and all symptoms listed above; all appeared approximately September 15, 2024. Since the purchase of the vehicle in January 2024, I have made complaint regarding the performance of the vehicle. Have had multiple oil changes/fill ups within the last 7 months, due to excessive oil consumption. Vehicle has had scheduled maintenance, several diagnostics, and too many trips to the dealership/repair for a 5 year old vehicle,...

In April of 2024 initially the car was under warranty. I took my vehicle to the Edmond Hyundai dealership to see why I kept having to put oil in the car in between oil changes. The dealership said iI needed an oil consumption test to determine if the loss of oil amount was excessive. They changed the oil and i drove it 1000 miles and returned it to the dealership. They said it was was around 1 quart low, which is acceptable and "normal". This isn't normal. I tried to get them to check the engine again and do other tests but they wouldn't. It is now October of 24' and I am still putting oil in between oil changes because the light comes on. I took the car back to the dealership on 10/19 and they said the only thing they could do is another consumption test to determine...

Around the 70,000 to 80,000 mile range, I began to notice that I needed more frequent oil changes. Additionally, when making turns, the oil pressure light would illuminate. I reported these concerns to the service manager, Steve Purvis, at Noblesville Hyundai, who advised that the light simply indicated the need for an oil change. Due to the ignorance of Steve Purvis, I took my vehicle to Hyundai of Carmel, where the issue was not addressed until I reached 97,000 miles. During this time, the valve covers were replaced twice, yet there were no active leaks, and the problem persisted. Hyundai subsequently denied my request for an oil consumption test to further diagnose the issue. I then took my vehicle to a different shop, where a mini oil consumption test revealed that my car burned over 2 quarts of oil from Friday to Monday. Additionally, my start/stop system has ceased functioning, preventing...

Car has a rod knock, has been looked at by a private mechanic, seen online there was a recall on Hyundai Sonatas for rod knock issues.

I have had to change my spark plugs 3 times since May due to the fact that I keep getting oil in them. My car also goes through an excessive amount of oil. Within 2 weeks of having my oil changed I had to start adding more oil. But it does not ever have any on the ground under my car. My piston oil rings are not keeping oil out of the area where my spark plugs are located.

Engine has been leaking oil for awhile. After close inspection i discovered a tiny crack in oil pan. There is no damage whatsoever to the oil pan. After much research online it appears many other hyundai owners have the same leak from a crack in oil pan in exact same spot. If left unchecked it would result in engine damage from low oil level. There is a spot weld for drain plug backing and the crack develops at this spot weld. No damage or impact has caused this crack as other owners experience same issue. Oil pan had to be replaced as leak was getting worse at crack

The contact owns a 2019 Hyundai Sonata. The contact stated that the vehicle was consuming an excessive amount of engine oil. The oil warning light was occasionally illuminated. The contact added a quart of oil, but the oil level failed to register on the dipstick. The contact stated that the vehicle was two quarts low in approximately 5,000 miles. The vehicle was taken to the local dealer, who competed an oil change and informed the contact to bring the vehicle back within 1,000 miles. The mechanic informed the contact that the vehicle was meeting the specifications for the oil requirements. The manufacturer was not contacted. The failure mileage was approximately 56,000.

I have noticed a great amount of oil usage here in the past 2 months, I have been having my oil changed every 4,500 miles for the last 4 years. After having it changed 6 weeks ago I was coming home from work and my oil light came on so when I got up the next morning I went out and checked the level of my oil and it was barely any oil in my car, so I immediately added the oil I needed to fill what was needed . I then started to monitor my oil levels and it seems that my car was using about a quart to a quart and a half every 6-7 days, I took my car to the mechanic shop and they told me return my back to the dealer because they have been seeing at least 3-4 Hyundia's weekly come in with the...

The check hybrid system malfunction light and the blind spot detection came on january 13 2024 for the forth time towed to dealship they attempted repair then again same issue for the fifth March 23 2024 and the last time was today June 7 2024 was towed in.

The contact owns a 2019 Hyundai Sonata. The contact stated that the engine was consuming an excessive amount of engine oil. The contact stated that the check oil warning light was illuminated. The contact stated that the vehicle was consuming 4-quarts of engine oil per week. The contact stated that the dealer and the manufacturer were notified of the failure, but neither offered any assistance. The vehicle was not repaired. The failure mileage was approximately 45,000.

The vehicle consumes a gallon of oil weekly. The spark plugs are having to be replaced every three months. The Low beams have been replaced and are working but the headlights are completely out and flashes on the dash board. I have Hi beam’s only. There is an electrical issue with the vehicle and is very dangerous to drive with the oil leaks that are continuously happening.

Less than 70,000 miles and engine is loosing oil

The contact owns a 2019 Hyundai Sonata. The contact stated that while parked and powered off, the vehicle was being refueled and connected to the fuel pump when she observed smoke coming from vents and from the engine compartment. The contact opened the hood of the vehicle and she observed fire emanating from the engine compartment. The gas station attendant extinguished the fire with an extinguisher. A police report was filed. The fire department was not called. The vehicle was towed to a dealer but was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 125,000.

Engine oil consumption failure. My car would not even make it to the 3,000 mile oil change without the low oil warning light coming on. Brought it to D'Arcy Hyundai in Joliet, IL for the consumption test..after 1,000 miles my car was down 2 quarts! They then did a combustion chamber cleaning. This cleaning made it so my car lags as it's driving and wouldn't shift properly and before it even left the dealership, the starter went out. Brought it back and they claim that after 1,000 miles the oil reads FULL, not any oil used whatsoever-which isn't possible. They are now denying fixing the engine. I am furious and when I get stuck again due to the oil consumption issue, they will make me start all over again and it may not be covered due to being over the mileage shortly. (I have about 2,000 miles left of my...

Starting in July 2023 I have noticed that the oil consumption for my car is racing through the engine. I barely make it 1000 miles before the oil is completely gone. After 2 local oil changes - I decided to take it to the Hyundai dealer where I purchased the car. This was in October - I have brought my car in 4 times for 1000 mile oil consumption tests. I had to add an additional visit due to the fact that Hyundai changed the testing standards. Now I have to bring it again today - Hyundai has not told me what the next step is other than I have to leave the car there all day - after they speak to tech support they will determine next steps. Most likely a combustion cleaning. Then I have to start the 1000 mile consumption tests again. I live 35 mins from...

Engine burns oils horribly. Cannot sell car due to oil issues. Paint is chipping on exterior of the vehicle.
