Excessive amount of oil burning. Was told that this vehicle had a engine recall, and I am trying to see what I can do about it before it blows up.

.Car is using or burning alot of oil. After oil change. It went 2800 miles on the oil change and the cars oil light come on. Checked oil and nothing on the dip stick. Headlights randomly shut off at night. Had the wiring checked and didnt find any issues
What component or system failed or malfunctioned, and is it available for inspection upon request?\n' + 'The engine in my 2017 Hyundai Sonata is defective. It burns oil excessively, fouls spark plugs and ignition coils, and causes continuous misfires. The engine is still in my possession and available for inspection.\n' + 'How was your safety or the safety of others put at risk?\n' + 'The engine misfires cause my car to shake violently while driving, lose power unexpectedly, and turn on the check engine light. This creates a risk of stalling or losing control while driving at highway speeds, endangering myself and others. I no longer feel safe driving the car.\n' + '\n' + 'Has the problem been reproduced or confirmed by a dealer or independent service center?\n' + 'Yes. Multiple independent mechanics have confirmed that the misfires and repeated spark plug/coil failures are caused by the engine itself, not just normal wear. Hyundai dealers acknowledged the excessive oil consumption and advised combustion cleanings, which did not resolve the issue.\n' + '\n' + 'Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?\n' + 'Yes. The vehicle has been inspected by multiple Hyundai dealerships (including McGrath Hyundai) and independent service centers (Pep Boys, AAMCO, and others). All noted ongoing oil-related issues and repeated failures tied to the engine.\n' + '\n' + 'Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?\n' + 'Yes. The check engine light has come on repeatedly over the last two years. Symptoms include rough idling, heavy shaking, loss of power, and repeated ignition coil and spark plug failures (monthly or more often). The problem began within the first year of ownership and has persisted ever since despite repairs.
My 2017 Hyundai Sonata Limited check engine light came on at approximately 103,000 miles of use. This happened last week. The code it was pointing to was a faulty Fuel Pressure Sensor. Could also be combined with faulty fuel pump, but the primary code indicates the sensor. I will be taking it in to the Hyundai dealership shortly. The main reason I’m reporting this is because of my previous experience owning a 2011 Hyundai Santa Fe that had to have the engine replaced three times all under warranty. There ended up being a class action lawsuit because of several owners experiencing the same proglem. While this may not be the same case, I am Leary of engine problems like this. I take very good care of my cars with regular maintenance, so I’m reporting this just in case others are experiencing the same problem.
I have recently acquired this vehicle. There has been zero unrecorded recalls, and I have been told that there is an active recall on the engine in this vehicle. I am inquiring this. The car has recently been taken to my mechanic and he has told me this plus the car engine is using a excessive amount of oil. I have heard that it is possible to have the engine replaced due to the recall I am inquiring about that. On the date of the incident that has occurred. I am putting the date of the purchase of the vehicle order that is on the Pohanka buyers order.
The engine was eating up oil and failed. I have regularly had to get oil changes within 1000 miles of each other. Kept oil in my car like spare gasoline to top off every 4-7 days. Took my car in immediately when the check engine light came on to which the dealership said I have been negligent in my oil changes. The check engine light never came on prior, and I had an oil change the day before it did come on. It put my safety at risk because the engine could have just burst at any moment, and to my knowledge nothing was wrong since I was regularly putting oil in or getting an oil change. Yes the issue has been confirmed by the dealership. There was no warning other than the low oil light continuously coming on. I took it into the dealership last Spring to which they said there was no issue.
I am leasing a 2017 Hyundai Sonata from Car City in Michigan. In May 2025, the vehicle received a brand-new engine replacement due to previous problems. I picked the car up on [XXX], and on the same day, the vehicle began malfunctioning. It would not accelerate properly, jerked and stalled, and multiple warning lights — including the check engine light — came on immediately. This made the car unsafe to drive. I contacted the dealer, but they told me to wait until Monday to get it looked at, leaving me with a dangerous and unreliable car. The vehicle had already been in the shop for over two months for the engine issue, and I had only driven it for six months beforehand. I believe the repair or replacement engine is defective or was not properly installed. This creates a serious safety hazard. A car that stalls while driving puts everyone at risk. I am filing this complaint so this issue can be investigated and addressed if others are affected. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The engine in my 2017 Hyundai Sonata has been burning excessive amounts of engine oil over an extended period. The issue started approximately 10,000 miles ago but has worsened recently, requiring frequent oil top-offs between regular oil changes. The oil consumption is abnormal and not consistent with normal wear. This excessive oil burning poses a potential safety risk, including possible engine failure, stalling, or fire hazard due to low oil levels if not monitored carefully. The vehicle has not yet experienced a complete failure but the risk concerns me. The problem has been observed consistently during normal driving conditions. I have not yet had an official inspection or oil consumption test performed by a dealer, but I intend to request one. There have been no warning lights related to the oil burning issue, but the oil level drops rapidly and noticeably.
Constant losing oil, constant changing of spark plugs, car shaking, can't pick up speed
I am writing to request a Goodwill replacement. My car is burning oil faster than I can put it in. The engine heats up so bad that I feel it could catch fire at any time. I loose acceleration because of this, its an extreme safety hazard for myself and other motorists on the road. I am just now finding out about the issues Hyundai sonatas are having with this said problem. I would like it fixed asap.
My 2017 Hyundai Sonata has a major oil consumption problem. The car does not leak oil. It burns oil average 3000 miles. I have to add 5 to 6 quarts of oil every time I bring it to the shop and ask about it they tell me Hyundai has a problem with one of their engines, I see the recall on other models, but not my model. it’s been ongoing for about a year.
Engine started making a noise and then the car died and would not start. We were on the highway service road when the car died in the middle of the road. We took the car to the dealership and they confirmed the vehicle engine has seized up. This is covered under warranty. The manufacturer denied the claim because of a sensor recall in August 9, 2018. We purchased this car used on July 11, 2018 and never received the recall notification for this sensor. The manufacturer is refusing to repair the engine that is under warranty.
Premature rod bearing failure at 126,750. Dealer said there was extended warranty for this failure. Turns out that Hyundai denied this because they say Recall 953 was not done. This does not reflect what I show, I show this a Service Program and probably a notice does not get sent out. I have gotten an estimate for $7848.50 for engine replace. I do not agree with this decision since it is a know problem with multiple class action lawsuits.
All documents are attached as it is many separate incidents that ended knock from motor and minutes later, a piston shooting through the engine block which is what made the car inoperable
I am writing to request your assistance in enforcing the terms of the class action settlement and extended warranty coverage for my 2017 Hyundai Sonata (VIN: [XXX] ). Despite clear evidence of a defective Theta II engine, Hyundai Corporate has refused to authorize a full engine replacement unless the engine “blows” completely. This directly conflicts with the express terms of the “In re: Hyundai and Kia Engine Litigation” settlement, which requires Hyundai to cover any engine exhibiting failure‐mode symptoms. Below, I have summarized all relevant facts, diagnoses, and correspondence. I purchased this Sonata used from Oakes Kia (Kansas City, MO) in May 2023. At the time of purchase, the vehicle had 77,000 miles. To my knowledge, I am the third owner of this vehicle. Since I bought this car, I have followed the manufacturer’s recommended maintenance schedule: All routine oil changes (every 5,000 miles, or sooner) at Oakes Kia, plus one oil change at Northtowne Hyundai in April 2025. The engine currently has approximately 98,650 miles. I have driven it about 1,000 miles since December 2024 to avoid further damage and due to the danger, it puts me and others in on the road. Since December the vehicle has had persistent shaking, hesitation on acceleration, strong odor, and illuminated Check Engine Light. Car condition has worsened since last oil change and even after coil packs and spark plugs were replaced, there was no improvement. The last oil change was done at Oakes Kia along with a tire rotation and multi-point inspection. They Installed UM018 CH074: Mobil SP 5W30 SN, 21513 23001: Gasket-oil plug and 26300 35505: Filter assy-engine O Service Advisor, Fernando Perez said they did not identify root cause of the shaking, hesitation and strong odor; they instructed me to return to the mechanic who had replaced spark plugs/coil packs, possibly I got a bad spark plug or coil pack. I did this, it was not the problem. I have files to share but they are too big! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO
I purchased this car in 2018. Noticed it would be low on oil frequently by year one of having it I took in in for regular maintenance at the dealer by year 2 car began giving me more issues with oil and engine I have had the manifold replaced and other parts in the engine several times and keep running into the same issues and from what I found out I’m not the only one dealing with oil consumption issues I was told by the dealer this is a regular issue with this car and that Hyundai will not cover it I feel it’s very unfair to the consumer that they did not disclose this to me when I explained I needed a dependable vehicle because I had a disabled child I have put so much money in this vehicle I could have bought a new one by now
Engine seized on me, lurched forward, then engine light starting flashing and I could barely accelerate anymore. Had to go very slowly to make it home. My local autoshop says this is very common with Hyundai's and there was a recall for bad engines for this.
2017 Hyundai Sonata having severe oil consumption issue. Having to top off with a quart of oil every 500 miles. Was purchased last June and has been a nightmare since. We contacted Hyundai consumer affairs and they opened a case and made an appointment for us to go to a local Hyundai dealer. The dealership told us we didn’t qualify for oil consumption test be cause we are second owners and the vehicle had 62,000 miles on it. We did purchase an extended warranty when we bought the car but they won’t cover oil issue. Local mechanic won’t touch it and refers us to Hyundai dealer. Just getting so frustrated and worried about car safety and engine damage. I read on another sit that Hyundai issued an oil consumption recall in 2025 but our vehicle is not listed. Please help us.
The car went into limp mode activated by the knock sensor. Audible knocking noises were emitted. Hyundai dealership replaced knock sensor. Car drove 63 miles before knocking noise repeated and car went into limp mode. Hyundai dealership requested new engine as problem is covered by extended warranty for known issue. It has been declined by corporate office. Car is at dealership and unsafe to operate.
The contact owns a 2017 Hyundai Sonata. The contact stated that the engine was consuming an excessive amount of engine oil. Additionally, the engine was leaking oil onto the ground, and smoke was coming from the engine compartment while driving. The vehicle was taken to Walmart for an oil change. The contact stated that after the oil change the engine consumed two and a half quarts of oil after driving a thousand miles. The vehicle was taken to the dealer, who performed an oil consumption test, and the engine passed the test. The vehicle was not repaired. The contact stated that the failure persisted. The manufacturer was made aware of the failure and a case was filed. The failure mileage was 92,672.
The 2017 hyundai sonata 2.4L excessively consumes oil. I constantly put oil in my car. My fear is that I will have a critical engine failure during commute and will be fully responsible for replacing the engine even though hyundai motors designed a poorly built engine. Every time I search Google about the make and model it is always hundreds of other hyundai sonata owners with the same problems and fears that their car will break down or have already had their engine replaced. I would like to see an investigation take place on the 2017 hyundai sonata 2.4L engine. It is poorly designed and consumes more than enough oil in a short amount of time to cause engine failure.
Engine burning oil like crazy never had to put so much in for any other car. Risk of engine lock without enough oil also sets of the knock sensor. Every time I get an oil change they let me know that I’ve burned most of my oil and that it’s low so I just started doing my own oil topping it off. Problem has been ongoing since I got the car.
I am writing to file a formal safety complaint regarding my 2017 Hyundai Sonata which suffered an unexpected engine seizure on January 22, 2025, while my daughter was driving. The incident occurred without warning and left her stranded in a hazardous location, putting her in immediate danger. This appears to be part of a wider, documented issue affecting Hyundai vehicles. My understanding is that engine failures—particularly in Sonata models—have been the subject of recalls and class action lawsuits. However, Hyundai Motor America has refused to replace or repurchase the vehicle. Instead, they replaced the engine with one that now carries less warranty coverage than the original (12,000 miles vs. 26,000 miles remaining). Since the engine replacement, the vehicle has presented new problems, and now needs a new battery after sitting on the lot for so long. Hyundai has failed to offer meaningful support, leaving my family without a reliable vehicle for over two months. Hyundai has refused to replace or repurchase the vehicle, and I am now stuck with a car I cannot drive, cannot sell (due to the engine failure now reported on Carfax), and cannot rely on to safely transport my daughter. I believe this represents not only a serious safety risk, but also a pattern of negligence that could affect other drivers unaware of the risks. I respectfully request that the federal safety agency investigate this issue further and consider expanding oversight into Hyundai’s handling of these engine failures. I am available to provide full documentation, service records, and communication history.
I am seeking a resolution to the concerning and potentially dangerous issues that I have experienced with my vehicle. I got it from Carvana Dec 2023 and only had it for a year, and I’ve only drove 19,000 miles on it before my engine cut off on me while on the highway. I was going 70 mph when the safety of my life was at risk. After, I tried to send it to the dealership, they let my car sit for a month before even looking at it, they couldn’t tell me because they let it die. My car was completely off. So i got no full diagnostic. I have personally endured the traumatic experience of my engine suffering catastrophic failure. Also, my vehicle was consuming oil at an alarming rate, necessitating frequent and costly refills. I would sometimes even go 500 miles before the due of an oil change and would be told that my oil is very low. I believe that these problems should not be considered normal wear and tear. The hybrid sonata 2017 had a engine recall and so should the sonata 2017 limited 2.4L.
The contact owns a 2017 Hyundai Sonata. The contact stated while the vehicle was stationary, the vehicle experienced an excessive oil consumption. The check engine warning light was illuminated. The contact stated that the vehicle required an additional quart of engine oil monthly. The vehicle was taken to the dealer, where it was diagnosed with excessive oil consumption. The dealer determined that the engine needed to be replaced and the repair would be out-of-pocket. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the dealer for assistance. The failure mileage was approximately 93,000.
My Hyundai Sonata sport had a Manufacturer defect causing oil consumption. When my engine starting having issues they replaced it for free. I got it back and the engine light came on so i called they ask me to bring it back and i did. They told me the code was a po326 powertrain control module or faulty knock sensor. They said the code was a history code and they cleared it out drove it and the light did not come back on. I picked it up drove it and the light came back on. I called they said bring back again and before it could get it back over there the transmission went into limp mode or safety mode. They said my transmission was gone and needed a a new one. $4385.44. I wasn't having any issues before the engine replacement. All other mechanics think something happened when the replaced the engine. I just dont want to be taken advantage of. Long Hyundai Chattanooga Tennessee.
The check engine light light is on now giving code p200a I was driving and the center console shut off and the engine died I had to pull over and start the car again it started but the check engine light light is on now for a p200a I’ve looked it up and everything I can find says there is a recall but my car isn’t in it so what can I do I don’t want to cause a fire or an accident because my car messed up o.

This is the third time after 3 “repairs” that I have had my car at the dealer in less than a year. Car went into “limp” mode while driving down the highway causing car to stall and not go over 20 mph. First time they said it was a technical update needing done. Second time said low battery power causing issue so I purchased $300 battery from dealer and now showing cylinder 4 misfire and recommend replacing spark plugs and oil combustion testing due to having to add 3 quarts of oil every 230 miles due to excessive oil consumption. Dealer said this will not fix the issue however so why would I pay to have it done if it won’t fix the issue. Luckily these three incidents of engine power loss hasn’t caused me to have an accident but what If in 3 months and my engine loses power without warning for the 4th time in a year it dies cause an accident. I have a case open with Hyundai but am getting nowhere. I feel like a measly engine replacement would cost less than it will cost if this causes a major accident soon.
I was driving on highway when all of sudden my vehicle began to shake hard and lose power, every time I stepped on the accelerator the check engine light came on, this happened on [XXX] in Los Baños, CA. My safety was at risk as all other traffic was going past me including semi trucks as I was trying to find a safe place to pull over out of harms way, as I was doing this the car shut off completely before I could even pull over. I had to get the vehicle towed to my local dealership where they had it for almost 3 weeks now, only diagnostic I’ve had back was that it has 2 misfires, one in cylinder 2 and the other in cylinder 4, and that it has no compression in cylinder 2. They said it isn’t covered under warranty which I believe should be looked into as I could of been serious hurt or lost my life due to this issues. I’ve had the vehicle serviced up to date since I’ve owed it and also noticed high oil consumption, not sure if this led to engine failure? The final diagnosis from Hyandai dealer is that engine is no good anymore and need replacement but it’s not covered under warranty.

My vehicle was purchased in 2018 and currently has 128,000 miles. I took it to the dealership because it was puttering and not holding pil. The dealership did some work on the vehicle. Furthermore, after that trip to the dealership, my car kept burning oil even after recent oil changes that I found myself constantly adding oil. I took it to another licensed mechanic who informed me after a tune up that my car is consistently burning oil. This was after I had a recent oil change. The engine is defective, hyundai knows they are defective and refuse to do anything about it.
