Engine And Engine Cooling Problems of Hyundai Santa Fe - part 2

On [xxx}, my 2020 Hyundai Santa Fe sel 2. 0t (VIN: [xxx] ) experienced sudden complete engine failure accompanied by a strong burning smell. The vehicle would not start or turn over, stranding me and creating a safety hazard. The burning smell indicated potential fire risk. This appears to be related to the known theta ii engine defect that has caused multiple recalls and engine fires in Hyundai vehicles. Despite dealer confirmation that the engine was clean and well-maintained with no customer fault, Hyundai has denied warranty coverage. The sudden failure pattern with burning odor represents a serious safety defect that could endanger drivers and passengers. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine has been running rough for awhile and emissions light came on. My car was having problems accelerating, 2 years ago the light came on but didn’t stay on so the dealer couldn’t diagnose problem.

At first I noticed that there’s a strong smell of oil when I am driving it. The engine was consuming a large amount of oil so much so that I have to keep an extra bottle of oil in my car. I will be driving and oil light shows up and I have had an oil change not just a week prior. I had an independent mechanic to come check it and he said a lot of oil is leaking out into the engine because, I never see any oil on the ground. Then finally the check engine light is on, the steering is shaking heavily and I have stopped driving it for my safety and that of others on the road.

The contact owns a 2017 Hyundai Santa Fe sport. The contact stated that while driving at an undisclosed speed, the low engine oil warning light illuminated, prompting the contact to inspect the dipstick. After a visual inspection, the contact observed that the oil was abnormally low, though the vehicle had been serviced less than a month prior. The vehicle was taken to the dealer, who performed an engine oil consumption test and found that the vehicle consumed one quart of engine oil in 360 miles. The contact was informed that the engine needed to be rebuilt or replaced. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 103,000.

The contact owns a 2020 Hyundai Santa Fe. The contact stated that while driving at 45 mph, the check engine warning light illuminated. After scanning the vehicle, the contact received a code for torque converter damage. The vehicle was taken to the local dealer, where it was diagnosed, and the tcm update was needed. The vehicle was repaired, but the failure recurred. The vehicle was taken back to the local dealer, where it was diagnosed with transmission failure. The vehicle was repaired, but the failure persisted. The oil light was illuminated and then turned off. The contact became aware that the engine oil was 4 1/2 quarts low, and it was determined there was an oil consumption issue with the engine. The vehicle was taken back to the local dealer, where it was determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, and a complaint was filed. The failure mileage was approximately 98,000.

Owner: [xxx] VIN: [xxx] vehicle: 2014 Hyundai Santa Fe sport my daughter purchased this vehicle in April 2025 from a licensed Chrysler dealership. On [xxx], the engine suddenly seized while driving, without warning, and would not restart. This VIN was part of recall 17v-226 (Hyundai campaign 162). Dealer records show the recall was closed with inspection only (“engine inspection, oil, dipstick”), not an engine replacement. The failure matches the defect description of the recall (bearing wear from restricted oil flow). Hyundai is refusing to repair it, claiming sludge and “maintenance neglect,” despite my daughter only owning it for 5 months and having an oil change at Hyundai in may 2025. This engine failure proves the prior “inspection” remedy was ineffective. Hyundai is also denying coverage under the lifetime warranty extension (txxi), which explicitly applies to subsequent owners for bearing failures. This is a serious safety issue. My daughter lost power in traffic, and the vehicle is still unrepaired. This complaint is being submitted on behalf of the registered owner, [xxx] , by her mother [xxx] , who is the primary contact. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle has been taken in for routine oil changes and other routine maintenance since purchasing in January 2024. On 9/4/2025, just before arriving home from work, the oil light came on. I checked the dipstick and it was dry. There was no oil in the engine. The last oil change was ~3600 miles ago (regular intervals of 5,000 with synthetic oil). I added two quarts of oil before driving anywhere. On 9/5/2025, I took the vehicle into a shop to have the oil topped off and asked if there were any obvious signs of a leak. The mechanic noted there were no signs of a leak, but added that Hyundai had a lawsuit about the theta ii engine consuming an excessive amount of oil and to look into it. Upon looking into the lawsuit, it came to my attention that my vehicle has this engine and this is a likely culprit to the problem. This report was advised to work toward a resolution to the issue.

I purchased my 2019 Hyundai Santa Fe on October 29, 2021. Since then, I’ve experienced a series of mechanical and electrical failures that I believe are far beyond normal for a vehicle of this age. - the remote start has never worked. - on October 20, 2023, the hatch latch failed. The only way to open it now is by climbing into the back and manually pulling the latch. - on October 27, 2023, the electric power steering failed. I had to replace the entire steering column at a cost of $4,000. - the paint began deteriorating prematurely and required a full repair. Hyundai covered this under warranty, but the cost was $8,000. - in early spring 2025, all coil packs had to be replaced due to misfires, costing approximately $500. - September 4, 2025, the car stalled while I was driving on a main road and I had to pull over. There were no warning lights and I started home. About a mile from home check engine light came on so contact mechanic. Ended up towing to a dealership and was told the engine must be replaced because the oil had burned off without any warning from the oil light indicator. The turbo also needs replacement. - the combined cost is $14,000. These failures have caused significant financial hardship and stress. I am currently $17,000 underwater on the loan, and the repair costs are overwhelming. The lack of warning before catastrophic engine damage is especially concerning. I believe these issues reflect systemic defects in the vehicle’s design and manufacturing. The repeated failure of critical components—especially the steering system and oil monitoring—make this the worst automotive experience I’ve ever had. I respectfully request that the NHTSA investigate these failures and determine whether Hyundai should be held accountable. Consumers deserve protection from vehicles with such extensive and costly problems.

Check engine light came on at 100,400 mile while on the freeway and car went into limp mode. Mechanic found p1326 code and the engine knocking. Tried to drive it to the dealership and the engine seized up. Towed it to the dealership and waiting to hear if Hyundai will pay for a new engine under their extended warranty campaign.

The engine starting consuming a quart of oil in less than 500 miles of recent oil change. Car has 114,000 miles and due to oil consumption lifters are now ticking louder. I was not notified of the class action lawsuit that happened due to this same issue. Oil pressure light came on.

While driving the car, started to smell gas and saw smoke. Tried to pull over and abs lights came on and lost brakes. Was able to stop using emergency break. Car was completely engulfed in seconds.

On [xxx] in rehoboth, DE, my 2023 Hyundai Santa Fe experienced a sudden and complete power failure while reversing out of a parking spot. All electrical systems shut down—including propulsion, dashboard lights, and emergency brake—causing the vehicle to roll backward into oncoming traffic. No warning lights appeared beforehand. After about an hour, power returned on its own. A passing police officer witnessed the situation and a report was filed with the rehoboth beach police department. On September 6th, Hyundai service performed a diagnostic scan of the engine and transmission systems. No fault codes were found, and the issue could not be replicated. After sitting overnight, the vehicle restarted normally and passed a road test. The dealership documented the incident but returned the vehicle without repair, stating: “cannot duplicate concern at this time. ” I was advised to tow the vehicle in if the issue recurs and, if rolling occurs again, to use a wheel chock. I purchased this vehicle new in 2023. It has only 40,000 miles and is covered under a 10-year bumper-to-bumper warranty. A failure of this magnitude—especially during a basic maneuver like reversing—poses a serious safety risk. Despite the dealership’s inability to replicate the issue, I do not feel safe operating the vehicle until the root cause is identified and resolved. I am currently in the process of escalating to Hyundai corporate for further investigation, including a buyback review, replacement evaluation, or extended diagnostic protocol.

I was driving home Friday August 29th 2025 around 10:30 am on I-70 w when I began to have trouble accelerating my vehicle. There were vehicles trailing closely behind me so I increased pressure on the gas pedal. I would feel my car forcibly trying to compensate and the rpms on the vehicle increased significantly. The check engine light then illuminated and the car stedily beagan to decelerate although rpms were increasing and the force on the gas pedal was at its maximum. I could no longer get past 30 mph. The cars behind me had to quickly change lanes behind me to avoid rear end collision and I finally pulled over to the shoulder of the highway but it was a very narrow shoulder so my safety and the safety of those driving around were compromised because they could have easily resulted in a high speed rear-end collision that could have been fatal and the location of my car on the shoulder was not safe and I could have been side-swipped waiting for a friend to come get me and for me to move my car off hat narrow shoulder. I was frantic and very emotionally distressed by this incident because all the maintenance on the car was up to date and there was no check engine light on in the car prior to this incident. The unexpected and decelleration and inability to compensate on the highway was very unsafe. I have taken my car to the delearship and they have yet to address my engine issues or the safety concerns. The rep actually laughed while I was recounting the events. I also called hagerstown police department to have a police officer come out to the breakdown site because I did not feel safe but my frined arrived before the police.

This vehicle is burning oil. It burned out a spark plugs and almost caused a crash. Purchased from dealership 6/26/2025.

In relation to this incident, approximately 3,00 miles after an oil change, the engine oil drain plug fell out and caused all oil to leak and cause engine damage. Engine oil change was at approximately 125,000 miles. Drain plug fell out at approximately 128,000 miles. No warning lights or symptoms were present prior to vehicle shutting off and dying while driving. Vehicle was then towed to shop who previously did oil change. Shop confirmed drain plug was missing and oil level was empty. I am the manager of this shop submitting this on behalf of the customer with this vehicle. We are aware of the ongoing concerns in relation to case dp22-003 and would like to submit this information as further evidence for this case.

While driving on a steep, narrow grade with no safe shoulder, my 2014 Hyundai Santa Fe sport suddenly lost all forward power. The engine would rev but the vehicle would not accelerate. I was left stranded in traffic, with cars behind me and nowhere safe to pull off, creating an immediate risk of being rear-ended or rolling back into other vehicles. I had to call for a tow to avoid a serious crash. The vehicle was marked as having all recall campaigns completed, including the rod bearing inspection and knock sensor update, which were supposed to protect against catastrophic engine failure. Clearly, those campaigns were not sufficient to prevent the failure I experienced. At the time of failure, the vehicle displayed the check engine light and drivability symptoms consistent with abnormal combustion and potential bearing damage. Hyundai denied lifetime warranty coverage under the theta ii engine settlement without performing the required inspection. Instead, I was left with an estimate for engine-related repairs that exceeded the value of the vehicle, effectively rendering it a total loss. This failure is exactly what Hyundai’s recall notices describe as a risk: sudden engine failure, loss of motive power, and increased risk of crash. The fact that this happened to my vehicle despite “completed” recall campaigns raises serious concerns about whether the defect remains unresolved and whether Hyundai is adequately honoring its recall and settlement obligations. I am requesting that NHTSA investigate whether Hyundai is improperly denying warranty coverage without inspection and whether vehicles that were marked as repaired under these recalls are still at risk of catastrophic engine failure, stalling, and loss of motive power on public roads. The settlement administrator also works for Hyundai is just referring customers back to Hyundai customer care. They are not honoring this class action lawsuit and acting in bad faith and putting lives at risk.

On 08/15/2025 I started the vehicle and heard a ticking noise that lasted for 3 seconds and stopped. The same noise happened when I would start the car in the mornings. It never lasted more than 3 seconds and I wasn't too sure what the noise was. There was no engine lights that came on so I wasnt too worried about it. On 8/21/2025 my husband went to the store and when he came back the car shut off while backing into the driveway. He said it made a weird noise and just shut off. We tested the battery but it was still charged. We brought it to our mechanic and he called us 15 mins later saying he found metal shavings on the oil filter and the engine had seized. He recommended going to the dealer, which is 90 miles away. Around the 15th we had received the warranty extension for 15 years/150,000 miles from Hyundai talking about a knocking sound that can lead to engine seizure. So I called the dealer and they said to bring it in. We got the car towed to the dealer on 8/26/2025. On 09/04/2025 they called to let us know that they ran the test on the engine but Hyundai was not going to help due to the car having 176,000 miles. They agreed the engine seized due to rod failure but wasn't going to offer goodwill assistance, even with the service history we submitted from our carfax that showed regular scheduled maintenance recorda. We bought the car on 03/08/2025 when it was at 170,000 miles. I knew about the other open recalls and had them fixed on 06/12/2025 ( after being delayed from the dealer for 2 months because they couldn't get the parts for the auxiliary canister). Luckily the car died in the driveway and not in the middle of traffic. Hyundai has known about their lambda engines having this issue and the kdss recall was not available for this car which could have triggered a lifetime warranty on the engine. I barely had the car for 5 months.

The engine shut down into limp mode. I was on the interstate and this caused me to slow down and cause traffic problems. Yes, I have taken my car to mccarthy olathe Hyundai and was told there was a recall for knocking and would not be fixed because I needed a new engine. My engine light came on and the car slowed down. As soon as this happened I took the car to the dealership to be fixed. I did not drive the car anymore.

The contact owns a 2018 Hyundai Santa Fe sport. The contact stated that while driving at 65 mph, the engine seized. No warning light was illuminated. The vehicle was coasted to the shoulder of the roadway; however, the vehicle was in an unsafe location. The contact and his wife exited the vehicle and stood further back off the roadway for their safety. The contact stated that because of the unsafe location of the vehicle, the contact and his wife were fearful of remaining in the vehicle. Additionally, other vehicles were driving by fast. The contact stated that the failure had occurred while on a trip. The vehicle was towed to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was informed that the repair was not covered under recall or special programs. The manufacturer was made aware of the failure. The failure mileage was approximately 100,316.

Number 4 piston developed a hole in it. Also the engine has been going through a lot of oil.

The engine suddenly seized up on me. Was told by my mechanic that that year and make once they get to a certain mileage gets premature engine failure. I looked it up and that year has a huge problem with this issue.

Engine siezed, causing me to have to tow my vehicle. I was moved in the military to germany in 2019, I had to have no open recalls on the car before I shipped it overseas. I completed a recall on the 5th of January 2019. On the 10th of January, Hyundai activated another recall on the vehicle. I was unaware of this recall and shipped my vehicle to germany on the 16th of January 2016. The car returned from germany in September of 2023. I had zero issues with this vehicle while I was over there, no check engine lights, no warning lights, nothing. I always changed the oil when told to do so, and when I returned from germany it was the same thing, no issues and always completed oil changes when it was needed. I had no idea of the recall, Hyundai was sending it to an address I no longer lived at. I had no reason to take my vehicle to Hyundai to check for recalls. On [xxx], my vehicle engine stopped working at 84622 miles, and Hyundai said that it would be covered under warranty, but because I did not complete the recall that was activated on the 10th of January 2019, they denied the warranty and now my car is worthless.

I am having to get an oil change every month for the past 6 months. My engine lights comes on every now and then, and my oil lights comes on every month. Something is wrong with the 2020 Hyundai Santa Fe's and the complaints are being ignored. I have never missed maintenace on my car since I purchased it in 2020 brand new. Even the places I have taken my car to get my oil changes said they have heard of the same issues with others that have the same year and make of car. I spends at least 45-55 dollars a month just for oil changes and sometimes 16. 00 in between the changes because the light will come on before it's time for the monthly change. Please help!!!.

Approximately six weeks after purchase, my daughter drove the vehicle to a school event and back without issue—no warning lights, noises, or drivability concerns. Shortly thereafter, when attempting to leave for another event, the Santa Fe failed to start. I attempted a jump-start, only to discover that the engine had seized suddenly and without prior warning. It is available for inspection if needed. This sudden and unexpected malfunction could have happened while driving down the road and who knows what might have happened to include my daughter being seriously injured. The vehicle was towed to our local Hyundai dealer. Where the service team confirmed catastrophic engine failure. The engine has only been inspected by the local dealer. There were no warning lights, noises, or drivability issues prior to the engine failure. This engine failure happened on Aug. 16, 2025 references for review NHTSA recall report 17v-578 – notes crankshaft pin and bearing wear issues leading to potential stall.

I am the current owner a 2017 Hyundai Santa Fe sport. While I was driving my SUV on the highway at highway speeds at 60mph, the oil pressure and the check engine warning light illuminated all of sudden after around 1 hour of smooth ride. In the meantime, suddenly the vehicle lost motive power, the steering wheel seized and smoke came immediately. Losing motive power in running conditions and smoke coming out during failure could have endangered our lives. The smoke came out due to leakage of engine oil probably. The vehicle was stuck in the middle of the road. The vehicle was towed to the residence and then after Hyundai dealership. The dealer was made aware of the failure. The failure mileage was approximately 76,245 only. Before reporting to nhsta I have seen numerous complaints about high oil consumption and burnt valves on theta ii engines around 2017 santafe sport model and very similar occurrence of events happening to all while driving the vehicle on highways. Hyundai must need to provide support to this year model and make vehicles.

My engine failed at 113,000 miles. It just sounded like a diesel truck when I started it one day. There were no warning messages at all. It did not have any power above 45 mph. I took it to a Hyundai dealer and showed him the extended warranty letter I received from Hyundai. The letter said my specific engine should qualify for an extended warranty. However, the dealer (castle Hyundai of downers grove, IL) said because my engine failed due to timing chain failure and not connecting rod failure, Hyundai would not honor the extended warranty. That infuriates me! Hyundai should honor the extended warranty because their engine failed and it wasn't my fault. They know they have an engine problem but because my engine didn't fail exactly the way they projected it would fail, I'm screwed out of using my car. It also meant I had to purchase a new car which obviously wasn't a Hyundai. I hope you can push Hyundai to provide me financial relief or at least expand the engine warranty for others.

Bought car in 2022 when covid was still a problem. I had problems with the led screen on the dash turning off. It did come back after about 10-15 minutes. I had to pull over to the side of the road in the meantime. I brought my car in and no problem was found. I was told that there was no way they could order a $6,000 part if they could not reproduce the problem. I still have had this problem periodically, but it does not last as long. This can be a safety risk when the screen goes out when driving. My check engine light has gone off many time in the 3 yrs and 7 months of me owning the vehicle. I am asked if the light is blinking when this occurs. If I said 'no', I was told 'then you don't have to worry'. I had my car in to evaluate the engine light on, and was told not to worry that no code showed up (I did not get a service record if they didn't find any thing, despite me asking). The very next day I was stranded on a busy hwy. My car was towed to the shop. I barely got off the hwy as one of my fuel injectors was bad. I was 45 min from my home and the check engine light went on. I started driving home and called the service dept. I was told that as long as the light was not blinking, it would be ok, and I tomorrow I should call for an appt if it is still on. My car started to act up when I was nearing my home, but it was drivable. The next morning the light was still on. I did not feel safe driving it around and felt it was another fuel injector. I was driving my car to the shop and the car was slowing down a little at a time. By the time I was about 1/2 mile from the shop, my car was only going 14 miles per hour. I was driving on the side of the hwy with my flashing lights on. Very unsafe. I know that I have a lemon for a car, but not taken seriously, that is a problem. I have had many more times that my engine light was on and would bring it in for an evaluation. Sometimes things were found, other times not. I am concerned about that lack of concern.

My engine failed. Dealership put it through an oil consumption test which it failed. They ended up keeping my car for 3 weeks to build a new engine, add new belts, new spark plugs and new filters to go with the repair. After completing this repair they told me they noticed my air bag light on. They recommended a new sensor to fix it. Which I was to pay $600 for. I agreed to this and had it done. I picked up the car and had it for 3 weeks before the airbag light came back on. I brought it back to dealership. They assessed it and told me the problem actually came from the seat and the total. To repair the whole seat would be $2500+ I am the only owner of this car. It has never been in an accident where the airbag deployed. It is in it's original state. I feel this is a huge safety concern that should be looked into.

Engine suddenly failed as I was sitting at a stop light and now is making a rattling/knocking noise.

Engine stopped abruptly without warning while driving vehicle.

Subject: urgent safety & warranty concern – 2017 Hyundai Santa Fe sport (TSB #21-01-002h) dear Hyundai customer care and NHTSA, I am reporting a serious safety and warranty concern regarding my 2017 Hyundai Santa Fe sport (VIN: 5xyzt3lb6hg429615, mileage:97,320). The vehicle is exhibiting excessive oil consumption after an initial consumption test burning 3quarts of oil in 725 miles as well as causing damage to the intake manifold requiring it to be repaired and is consistent with the connecting rod bearing defect covered under Hyundai TSB #21-01-002h. This TSB extends engine coverage to 10 years/120,000 miles for precisely this issue. Despite this, my authorized dealer, premier Hyundai of moreno valley has refused to take immediate corrective action and is requiring me to drive an additional 1,000 miles before performing the repair — a delay that increases the risk of catastrophic engine failure and endangers vehicle occupants and other motorists. Key points: this is a documented defect with a known history of sudden engine failure. TSB coverage and my warranty should apply immediately, without dangerous delay. The dealership’s requirement to continue driving the vehicle is unreasonable and unsafe. I am requesting: immediate authorization for the engine diagnostic and replacement under TSB #21-01-002h. Confirmation from Hyundai that I am not required to continue operating a defective engine to “prove” the defect. Nhtsa to log this complaint as part of the ongoing safety concerns regarding Hyundai theta ii engines. Please respond within 5 business days with next steps. I am prepared to provide full maintenance history, documentation, and dealership correspondence. Sincerely, lisa miller 25579 clifton CT. 951-965-6757 lmiller@mvusd. Net.

The contact owns a 2012 Hyundai Santa Fe. The contact stated that while driving 80 mph, the vehicle made an abnormally loud banging sound, and there was smoke coming from underneath the hood and through the a/c vents, which blocked the visibility of the roadway. The contact was able to pull over to the side of the road. Upon inspecting the vehicle, the contact noticed that a significant amount of oil was leaking from the vehicle. There was no warning light illuminated. The vehicle was towed to the residence. The contact became aware that the VIN was included in NHTSA campaign number: 20v746000 (engine). The dealer was contacted about the recall repair. The manufacturer was notified of the failure and advised the contact to tow the vehicle to the dealer for repair, and a case was filed. The manufacturer informed the contact that the repair could not be covered under the recall due to the vehicle having a branded title; however, the contact stated that the branded title was issued because the vehicle had sustained cosmetic damage from hailstone impact. The failure mileage was 133,000.

My 2016 Hyundai Santa Fe lost all power, shutting off and stopping abruptly in the middle of the road with no warning lights or “limp mode” being set off requiring my partner and I to push it into someone’s driveway with our two children in the car to get them to safety. We took the vehicle to a mechanic shop where we were told that to engine was seized and needed to be fully replaced with an initial quote starting at 8 thousand dollars for a replacement engine. I contacted my local Hyundai dealership and was told over the phone that the vehicle would be covered under Hyundai service bulletin txx8 that was issued last year due to ongoing issues with this engine (3. 3l v6 lambda ii). We paid to have the vehicle towed to this dealership only to be told that the warranty would not be honored due to a lack of maintenance records. I was able to provide Hyundai with all maintenance records from my ownership as well as records on the carfax report. They rejected the claim again stating that due to a lack of records not from my ownership they won’t cover it. After looking at the records I had access to again in critical detail I was able to find records that Hyundai missed, but they are unwilling to reevaluate the claim without me providing what they call additional records. I have contacted Hyundai, to try and resolve the issue and have gotten no resolution. The prior authorization team has stated that I have “adequate records” but still insist on denying the claim. The dealer has quoted me $12,000 for the repair that the warranty should be covering due to the engine not being manufactured in full anymore due to the issues that have come from it. The dealership (and private mechanic) would have to order individual pieces of the engine to build it themselves on site. If this engine is a big enough problem that Hyundai cannot provide a full engine replacement at market value then it should not be operating on the road at all.

I am reporting a sudden engine failure involving my 2017 Hyundai Santa Fe sport 2. 0t. At just 68,000 miles, the vehicle experienced catastrophic loss of power due to zero compression in cylinder 1. The vehicle is equipped with the theta ii turbocharged engine, which has been the subject of previous investigations and safety recalls due to premature failure risks, including stalling and fire hazards. This failure occurred on [xxx], while I was driving on the highway. There was no warning. It put all drivers near me at risk as I had no power, was traveling in the left lane and had to navigate through 3 lanes of traffic to reach the breakdown lane. I request that this case be investigated further as a potential safety risk and recurrence of known issues with this engine type.
