1 Engine And Engine Cooling problem

Failure Date: 10/01/2025

My car is needing an oil change almost every 3 weeks at this point. Mechanics say there is no leak and there may be a recall for gdi engines that are burning oil very fast. This is a reoccurring problem and would love to find out if I can get this recalled like I seen other 2017 Hyundai Sonatas.

2 Engine And Engine Cooling problem

Failure Date: 09/17/2025

To whom it may concern, I have own my vehicle since Jan 2018, which was purchased from the dealership's owner w/less than 10k miles. Maintenance has been performed iaw Hyundai's recommended schedule. However, yesterday, I was informed that my vehicle needed a new engine and other replacements totaling $13,934. 89. This is outrageous. How can a well kept vehicle w/106445 miles, need such replacements? thus your assistance will be greatly appreciated.

3 Engine And Engine Cooling problem

Failure Date: 09/16/2025

The engine shut off on the highway on two different days. Vehicle was going between 65 and 70 mph. The vehicle engine shut down and all the warning lights came on. Every one. The vehicle still moved but nothing inside worked, it ran on battery mode for the 17 miles to the dealership with a maximum speed of 60 mph. The risk was the immediate unresponsiveness of the vehicle and the sudden and immediate reduction in speed and power. It presented itself twice in about 2,000 miles. The dealership charged a 491$ diagnostic and found all the warnings and reset it, not reason for it happening and sent me on my way. Then it happened again. Brought back to the dealership and they tried to say they did another diagnostic and called the tech helpline. It took hours and they still don’t have a definitive answer, wanted to try almost 2k in repairs to see if it would fix the issue without any guarantees it would. Warning lights, all of them came on, cruise control, abs, engine light blinking, steering, literally everything and messages started running through the information center.

4 Engine And Engine Cooling problem

Failure Date: 09/07/2025

I purchased my 2017 from Hyundai motors of America in 2017. I am the only owner. I took the care in for a recall for campaign 953: ecm & cluster update-engine monitoring logic product improvement to have a a knock sensor placed on the engine to monitor the vehicle for signs of engine failure in 2022. The car has been showing signs of engine failure since the knock sensor was placed on the vehicle and Hyundai claimed that the knock sensor was bad and replaced in. Last week while I was driving the car ok the interstate at 70 miles per hour, the engine stopped running completely while driving. The check engine light did not illuminate until after the vehicle’s engine stopped running. The vehicle lost its ability to accelerate while driving. I was almost hit by a semi as I tried to guide the disabled vehicle to the emergency lane. I took the vehicle to one of the Hyundai dealerships for an inspection. The inspection shows engine failure due to internal failure. The knock sensor from campaign 953 failed to detect any engine problems. I called Hyundai motors of America and was given a case number (41539529). Even though the dealer reported to Hyundai motors of America about the engine failure, Hyundai motors of America is refusing to fix the vehicle due to mileage even though there is an extended warranty through campaign 953. This company is a fraud!! the company wants me to pre-approve authorization payment for them to replace my engine at my expense regardless of the recall, and their negligence!! they are placing people lives at risk.

6 Engine And Engine Cooling problem

Failure Date: 09/01/2025

We are the original owners of this vehicle. Over the past year we have been having to put quart(s) after quart(s) of full synthetic oil into this vehicle. There are no leaks anywhere that the mechanic can find and no burning of oil from the exhaust. We don't drive the vehicle many miles but have to put oil in at least every few weeks. The mechanic stated the last few times we have taken the car in to get looked at that it is a known issue with this make/model. He stated there was nothing he could do and we needed to contact the manufacture. We have tried on numerous occasions to make contact as well as the dealership has as well with no resolve.

9 Engine And Engine Cooling problem

Failure Date: 08/04/2025

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.

10 Engine And Engine Cooling problem

Failure Date: 08/04/2025

What component or system failed or malfunctioned, and is it available for inspection upon request? the engine in my 2017 Hyundai Sonata sport is defective. Oil pressure failed testing, oil contamination was found on the oil pressure sensor and connector, and the vehicle has experienced excessive oil issues. The engine is still in my possession and available for inspection upon request. How was your safety or the safety of others put at risk? the vehicle has gone into limp mode on the highway, which caused a sudden loss of power and created a dangerous situation in traffic. The car also shakes, misfires, and loses power unexpectedly, which could lead to stalling or loss of control at highway speeds. I do not feel safe driving the car. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. Multiple Hyundai dealerships have inspected the car. One confirmed low oil pressure and oil contamination at the sensor. Previous visits dismissed the oil warning and charged me for oil replacement instead of identifying the underlying defect. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes. The vehicle has been inspected by Hyundai dealers multiple times. I also have two inspection reports from the same dealer just two weeks apart with contradictory findings the first showing no oil issue, the second confirming oil contamination and failed oil pressure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes. The oil warning light and check engine light have both come on. The vehicle has gone into limp mode, and symptoms have included shaking, misfiring, rough idling, and loss of power. These issues began months ago and have continued despite repeated service visits.

11 Engine And Engine Cooling problem

Failure Date: 07/26/2025

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).

12 Engine And Engine Cooling problem

Failure Date: 07/22/2025

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.

13 Engine And Engine Cooling problem

Failure Date: 07/18/2025

Purchased the vehicle and immediately noticed a drip in the driveway. I was concerned so I started checking the dip stick. I booked a diagnostic appointment with a Hyundai service center. I wanted to be sure I purchased a quality vehicle. Upon what I thought was a complete diagnostic, a cracked oil pan was discovered. I agreed to purchase and pay out of pocket, everything else had checked out. I was told I could drive while I waited for the pan to come in, service was scheduled. The car never made it back. I continued to check the dipstick but while driving on a very busy interstate, the engine light went on and lost power. I barely managed to get to the breakdown lane. A complete safety hazard. I was towed to the closest garage where the owner suggested he see’s 3-4 of these a week. He would not touch it, have it towed to Hyundai. I paid for another diagnostic and now a flat bed tow. Key Hyundai of salem nh accepted the vehicle. I paid another $498 to have an “engine tear-down” send a detailed finding report to corporate. I called corporate and filled my own case number. I was denied by corporate, I was told I was a subsequent owner. The dealership didn’t match, I’m denied because the engine didn’t seize because of rod issue. Well Hyundai is praying upon consumers. They knowingly initiated the kds recall and installed sensors to place a vehicle in “limp mode” so the rod isn’t the issue and they deny coverage. I paid a private mechanic verify cylinder 3 has low compression. Had the car not gone into “limp mode” the rod bearings would have failed.

14 Engine And Engine Cooling problem

Failure Date: 07/10/2025

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.

15 Engine And Engine Cooling problem

Failure Date: 07/01/2025

Engine is burning up full tank of oil in a few days there are no oil leaks coming from the car. The car has been expected and worked on by multiple mechanics. The engine lights keeps coming on.

16 Engine And Engine Cooling problem

Failure Date: 07/01/2025

The camshaft position sensor internal rubber plug is faulty and it allows oil to leak into the sensor housing. Ruining the sensor and the brushes and housing. It causes the check engine light to come on the idle races and car takes off on its own. Can’t drive it because it’s to dangerous. Once it takes off then it goes into limp mode and you can’t pull out because of no power. 40000 miles. The internet is full of owners having the same problem.

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.

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.

19 Engine And Engine Cooling problem

Failure Date: 06/03/2025

I noticed my oil was pretty much empty at one point. I don't know how long it had been empty but I had been driving the car for a long time. But I usually do my oil changes every 5000 miles so the fact that the oil was empty is definitely not a good sign. I did an oil change and replaced the drain plug in case that was the issue. I checked for leaks and there weren't any. After probably a couple thousand miles, the oil was out again. I took it to a dealership and the guy at the service desk said "I shouldn't tell you this, but a lot of them have that problem. You should get rid of it before the engine fails. " Hyundai knows that it's an issue but they refuse to fix it or do a recall. It consumes oil like crazy and there's even a facebook group called Hyundai oil consumption recall with about 5000 people in it. If the oil in the engine drains to empty, the engine could seize up and put people in danger. No warning lights have come on when the oil has run out.

20 Engine And Engine Cooling problem

Failure Date: 06/03/2025

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.

21 Engine And Engine Cooling problem

Failure Date: 05/16/2025

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.

It has been declined by corporate office. Car is at dealership and unsafe to operate.

23 Engine And Engine Cooling problem

Failure Date: 04/12/2025

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.

Me.

25 Engine And Engine Cooling problem

Failure Date: 03/27/2025

My 2017 Hyundai Sonata se is experiencing symptoms consistent with connecting rod bearing failure covered under Hyundai’s ksds extended warranty program. June 22, 2019: ksds software (campaign 953) installed, qualifying the vehicle for Hyundai’s 15-year/150,000-mile warranty coverage for bearing failures. August 2022: campaign 208 engine recall performed. Hyundai’s record shows Aug 15, 2022, while wright way Hyundai’s service history shows Aug 13, 2022 (discrepancy unresolved). March 2025 (100,238 miles): vehicle went into limp mode with tailpipe smoke and loss of power. It was towed to wright way Hyundai, which kept it for several days but returned it with “no issue found. ” the smoke continued. June 5, 2025 (103,996 miles): oil change performed. August 27, 2025: oil light illuminated, dipstick showed no oil. Vehicle now exhibits severe drivability issues consistent with bearing damage. Hyundai has incorrectly tried to reframe this as an oil-consumption issue and directed me to pay $600 for a combustion chamber cleaning. My issue is not oil consumption — it is a bearing-related failure already covered by warranty. Hyundai’s obligations include a no-cost inspection/diagnosis for connecting rod bearing failure, yet I have been denied that process. Despite repeated written requests, Hyundai continues to attempt phone communication instead of email, even addressing me by the wrong name in correspondence, which suggests reliance on standardized or generic responses. I have exclusively maintained the vehicle at wright way Hyundai, following Hyundai’s service schedule. I am resorting to filing this complaint because after weeks of email correspondence, Hyundai’s corporate agent refuses to help and the manager insists on only calling by phone — which I will not answer out of concern they will attempt to mischaracterize or dismiss my complaint verbally. This failure poses a safety risk because the vehicle has lost power suddenly and requiring restart.

26 Engine And Engine Cooling problem

Failure Date: 03/25/2025

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.

27 Engine And Engine Cooling problem

Failure Date: 03/17/2025

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.

Failure Date: 03/11/2025

Fail/malfunction 3/18/internal engine failure diagnosed by local avondale, az Hyundai dealership service - rod bearing failure suspected. Vehicle currently undergoing bearing clearance test to affirm this or any connecting rod issues, with possible need for total engine replacement. When googling "Hyundai Sonata hybrid 2017 internal engine failure," masses of reports generate from consumers with this model, complaining of same defect, as do numerous recalls for such defects that have been mandated for the model with range of years including 2017. Yet when searching with my VIN, it says no recalls have been mandated, in spite of the undeniable, widespread identical defect. Available for inspection. Safety risk: driving on the freeway in city traffic at 70-75mph, the engine completely stopped and all dash lights lit up at once. Vehicle had to be coasted to shoulder to wait for roadside assistance. Extremely hazardous to us in vehicle and to all around us with sudden, dramatic speed change in moving, constant freeway traffic. First time: our usual mechanics at pep boys did diagnostic but found nothing, the vehicle drove normally for them, yet they did our regular tune-up, oil change, etc. Two weeks later, the same event happened on freeway, identical to first time. We were very lucky that no crashes happened either time. Pep boys advised that Hyundai investigate the issue. Prior symptoms: no warning lights or sounds presented until the events themselves, when the entire dash lit up. However, in the couple of months before, there were occasional, slight hesitation moments in the motion while driving at any speed. Concerns: 1) it seems Hyundai is on track to want to charge me for an entire engine replacement, or for whatever engine repairs they deem, e. G. Connecting rods, for manufacturing defects that they are entirely responsible for, 2) no recall seems to be mandated yet for this VIN batch, and 3) too many consumers are in danger - physically and financially.

Failure Date: 03/11/2025

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.

31 Engine And Engine Cooling problem

Failure Date: 02/22/2025

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 February 22,2025 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.

Failure Date: 02/10/2025

Every few months my car’s engine struggles. It doesn’t start, or I have to try a few times. For whatever reason I need to get an oil change a lot more frequently than normal and I’ve been to the shop before and the shop tells me that my engine is recalled but it doesn’t say that on the website when I put my VIN number in. Whenever the engine stops working again sometimes the ac doesn’t work and it almost put my dog’s life at risk once.

33 Engine And Engine Cooling problem

Failure Date: 01/22/2025

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 NHTSA 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.

The vehicle had a recall to replace the motor for bearing failure. They replaced my motor at 101,000 miles. The second motor than failed for the exact recall of bearing failure at 65,000 miles on the new motor. They told me that since I had already have done the recall and my car was now out of warranty that I would have to pay 10% of the repair bill for another motor. This second motor should have been included in that recall.
