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.

- St.George, UT, USA

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 ago Then I was asked to replace the spark plugs and coils. These were replaced for an additional cost of approximately $300. After replacing this, the check engine light gave the same condition of third cylinder damage.. And the oil level continue to decrease The vehicle was left with the dealer for approximately 10 days. They stated that the engine needed to be cleaned due to possible carbon buildup for about $800 then they stated that the spark plugs and coils needed to be replaced with a specific brand and not the type that Was previously used. Then my vehicle was returned to me, performing sluggishly with the check engine light returning with the same condition of third cylinder misfire. An inspection is available. How was your safety put at risk? The possibility engine failure away from hom Has the problem been reproduced or confirmed by a dealer or independent service center? Yes twice Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?

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, with regular maintenance, and 3 owners. I have owned the vehicle for less than a year and I am UNABLE TO DRIVE IT DUE TO HYUNDAI STATING IT NEEDS A NEW ENGINE. It stalls when slowing and stopping, which it may or may not start back up - this happened a few times in the middle of traffic. It will not gain speed appropriately when moving from a complete stop, inhibiting me from keeping up with traffic. It shakes violently while accelerating, causing mishandling and ability to steer effectively.

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.

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 me from starting the vehicle. I have also noted that there are open recalls for Hyundai vehicles, yet my VIN is not recognized under these recalls. I have incurred significant expenses related to these ongoing issues. My safety has been put to risk because the oil can burn completely out and cause the car to break down in the middle of traffic like it has before. Hyundai dealership has confirmed the car has an oil burning issue, as well as an independent shop by the name of Auto Tech in Indianapolis. Auto Tech has also confirmed that the start/stop system is causing my car to not start. The oil pressure light is not consistent when my oil gets low. Some times it comes on, other times it does not.

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

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.

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 the dealer - I have had to hire someone to take me there to leave car - and I then have to take mass transit to work. There are never any loaners because they are booked months in advance. I have had to rent numerous cars for long distance travel due to the mileage meter of 1000 miles on my car - I am not allowed to go over - if I do have to start all over again. That happened to me the first time. My car is crap at this point - I am not able to use it as I should be able to and Hyundai is giving us the run around. I have been contacted about trading it in and getting a new Hyundai - what a scam. I am not the only person - there are so many of us - follow the chats on Facebook and Reddit - nobody is helping us. The staff said if your engine seizes - that would be great. People are seizing on highways - that is very scary to me. Why is this not recalled yet?
