2019 Hyundai Sonata Engine

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.

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 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.

The contact owned a 2019 Hyundai Sonata. The contact stated that while stopped at a red light, smoke was present coming from the hood and a burning oil odor was present inside the cabin of the vehicle. Moments later while driving, flames were seen coming from under the hood before the vehicle stalled. After exiting the vehicle, the front of the vehicle burst into flames. The local fire department was called to the scene and extinguished the fire. The vehicle was destroyed and later towed away. The cause of the failure was not yet determined. A fire report was taken at the scene. The manufacturer was notified of the failure. The local dealer was not contacted. The failure mileage was 60,000.

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 if the oil loss is excessive. I asked them to do a more thorough check of the engine and cited the previous time I brought the car in for the same issue that was not resolved. The mileage is now just over the warranty threshold, but they are still wanting me to pay for whatever service needs to be done to the vehicle, whether it's a combustion cleaning or a new engine. The safety of the car is of concern now and since this car is driven by the three drivers in the family, I do not want them put at a risk on the road if something fails because of oil loss and engine seize. Hyundai needs to be held accountable and honor warranty, safety, and service. The dealers need to help the customer and go above and beyond. The staff at Edmond Hyundai kept going back to the consumption test and all the steps they need to follow before they could send in a submission for doing a combustion cleaning when clearly there was an issue. I am beyond frustrated with the lack of concern for safety and customer satisfaction.

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.

See attached document for complaint.

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.

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 would not immediately start. After finally starting the vehicle the check engine light remained illuminated. The vehicle was taken to the local dealer who diagnosed that the engine gasket was faulty causing oil to leak from the engine. The engine gasket was replaced and the failure was remedied. The manufacturer was not notified of the failure. The failure mileage was 23,000.

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 same problems. So today as I was coming home from work I tried to accelerate and my car just started sputtering and slowing down so I had to gradually accelerate while noticing my engine light flashing, so I had to drive 30mph in order to get to auto parts store to get the code read for the engine light and the guy told me that he also has seen a few these same codes on the Hyundia's lately. I think this really needs to be addressed immediately and put on the recall list , because this is a serious problem because my car stalling in the middle of the highway is not safe and causing people some real life head aches and serious out of pocket money that we don't have , so now my engine has completely shut down and I don't have a second vehicle and i have to get my car to the dealer tomorrow to see what can be done. Safety and taking ownership of the problem should be #1 priority .

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 warranty) My sister has a Kia and the same garbage was pulled with her vehicle! She also had issues after the combustion cleaning costing her a starter, battery and alternator. HYUNDAI and EVERY DEALERSHIP knows this issued exists and the recall should be made immediately without all of this garbage.

We keep getting an engine light every 2-3weeks. That sets the engine in a safe mode (limp mode). The code comes up Knock sensor overheat. Tho inspecting the engine we have notice in that time frame the car is low 1-2qts oil. Once the oil has either been replaced or added to and code reset it drives normal. Again until 2-3 weeks and bam. A course now we know to check our oil. After hours of research, we see no recalls for our car. Tho many years back that have had the exact same issue. The issues also came to light when car hit around 80k miles.

The engine is leaking oil in my garage. The car has 50,000 miles and is constantly loosing oil. It is 100% dealer maintained, and is current on all scheduled service.

I bought this car 1 year and 2 months ago from a Hyundai dealership. The car was close to 73,000 miles. A few days after I got the car I started hearing this noise that sounded like a rattle coming from the front while accelerating to about 2,000 RPM. Due to my work, I went back to the dealer after 1,000 miles and explained to them about the noise and they duplicate it. The engine was consuming oil when I bought the car, I went back to the dealer and never did any testing on oil consumption. The problem got worst and worst. I started a claim with Hyundai Corp and I waited for 4 months to the an approval and they are only covering 50% of the engine. Dealer says I have to pay $3,200 to start engine replacement process, with no payment plan. Now I have a debt of $17k and no car. Engine has no compression on cylinder 3, which causes a misfire and makes the car unsafe to drive and leaves me unemployed with a child and bills to take care of. Thank you Hyundai, nice job .

There is excessive oil consumption with the engine in my car. Hyundai says 1qt per 1000 miles is “acceptable” however this is not acceptable and can lead to catastrophic engine failure and oil slick on roadways if not caught in time. This is a know problem with Hyundai/Kia at this time. In many cases Hyundai/Kia owners are left with a “lemon” of a new car that is currently in warranty. Some have been granted replacement engines that have not lasted 3000 miles. A recall must be issued in the name of safety on these cars. The manufacturer must be held accountable for the lack of quality that has been put out over the last decade.

After a year of issues, burning oil, changing spark plugs, my engine is dead. Hyundai has ignored issues and many times refused to pay for oil, parts, etc passing all costs to me. I have a loan of 15k and no car. Called and emailed their case management team—no help, no reimbursements. I have no equity-No property left. This was my only mode of transportation. Due to their slowness, I had to buy a new car and spend money I was not scheduled to spend. The financial stress and lack safety and unprofessional manner from Hyundai is at a new level-ridiculous.

The manufacturer was notified of the failure and a case number was provided. The failure mileage was approximately 220,000.

2019 Sonata is using/burning oil at about a quart every 600-800 miles. We are checking and adding oil constantly. Car is sluggish, especially when accelerating from a stop.

The engine is burning the oil faster than normal. There are no oil leaks. Called the dealership and they said it’s an oil consumption. I got an oil change March 3,2023 and my oil pressure light came on last Friday April 14,2023 as I was driving I pulled over and there was completely no oil in the car. The dealership told me to top it off until they can look it at. I topped it off Friday with two quarts of oil that I purchased from auto zone. I checked my oil again on Yesterday April 18,2023 and the two quarts of oil I put in was completely black

I noticed the problem when my change oil light started coming on several thousands miles before my oil change was due. I checked the oil and it was very very low. Much lower that it should have been at that point during the maintenance period. We added oil thinking maybe something had happened with the previous oil change. Made it to the next round of maintenance and a few thousand miles into that one, same thing. Oil light came on again. Extremely low oil levels. I called the dealership where I had purchased the car - I am the original owner - and they requested me to bring it in for an oil consumption test. It was an immediate request. No other questions were asked. After the dealership kept my car for 2 1/2 weeks we get a call that the "valve" was full of "oil sludge" and were accused of "maintenance neglect", although we can produce records, and due to that Hyundai Corporate said our warranty would not cover it and repairs will not be covered. We would be held financially responsible for a brand new engine. I declined the repair as we cannot afford the repairs at this time and told the dealership we will continue to monitor oil levels.

Well below the 5000-mile mark for an oil change, multiple times between multiple oil changes my oil light would come on. I would be at a stop light and the oil light would come on as soon as I start going again. Checked the oil when I got home and there was barely any oil on the stick. Found hundreds if not thousands of complaints about the engine burning oil very fast in multiple Hyundai's and Kia's for almost a 10-year span. This has yet to be recalled by Hyundai, this is a very dangerous situation that if it continues going unnoticed, could cause death or serious injury. It is a known issue at Hyundai dealerships, and they will fix it if it's still under the 100,000-mile warranty, but only if you bring it up to them. Hyundai/Kia has yet to fix the problem or do a recall that has been across multiple models for 10 years.
