This vehicle has been suffering from substantial engine oil consumption, burning oil at an alarming and unsafe rate. I have repeatedly brought the vehicle to Washington Hyundai to address this under the engine class-action lawsuit terms, but the dealership continues to run repetitive tests without a resolution. This is a critical safety issue. Excessive oil consumption poses a severe risk of sudden, catastrophic engine seizure or stalling while operating at high speeds on the highway.

My 2018 Hyundai Santa Fe is burning oil and I run the risk of engine failure. I have to check my oil level daily. The mechanic who performed my last oil change said he is seeing this frequently with this age Hyundai Santa Fe. He said Hyundai should be willing to replace my engine but of course they won't. I fear that I am going to be on the freeway and have sudden engine failure creating a risk for me and drivers around me.

While driving over the pass the car suddenly lost power and was running very rough. Luckily there was an exit close by that we took and the engine died on the exit. We were able to get it started and get to a parking lot where it died and would not start again. While trying to start it in the parking lot the check engine light came on. So, after a $375 tow to the nearest town the mechanic discovered a damaged spark plug and the compression test showed 0 psi. The scope showed a hole in the piston. The car also leaks and burns oil. The mechanic recommended scrapping the vehicle since it would not be cost effective to repair it. The mechanic said ours is the 6th Santa Fe in their shop with a blown engine in the past month. It has not been inspected by anyone else.

The driver window as well as the driver rear window fuse blows out. It poses a threat when you need to get the windows down in an event of emergency.

My 2018 Hyundai Santa Fe Sport (2.4L Theta II GDI, VIN [XXX], approx. 110,000 miles) has suffered a chain of engine and emissions-system failures that create a loss-of-power safety hazard. At about 80,000 miles, Hyundai replaced the original engine under warranty for excessive oil consumption, a defect Hyundai has acknowledged across the Theta II engine family. After only about 20,000 miles on that replacement engine, the catalytic converter failed and set a P0420 code. The vehicle now bogs down, hesitates, and loses power under acceleration. This is dangerous when merging or accelerating into traffic, where a sudden loss of power raises the risk of a collision. A restricted or failing catalytic converter causes exhaust backpressure and abrupt power loss, and the underlying oil consumption also risks low-oil engine damage and stalling. A catalytic converter should last far longer. This premature failure is consistent with the well-documented Theta II pattern in which engine oil consumption contaminates and destroys the converter substrate. It indicates the replacement engine Hyundai installed is itself consuming oil and damaging downstream exhaust and emissions components. I reported this to the dealer and to Hyundai. Hyundai declined to cover the catalytic converter, treating it as unrelated, even though its own warranty engine replacement is the direct cause. I am filing so this safety-related failure is documented. No crash, fire, or injury has occurred. INFORMATION REDACT

Bought this as a used vehicle with around 77k miles. The SUV was running fine for a little while until I drove onto the highway. It eventually began to bog down and there was hesitation and jumping instead of acceleration. This continued my entire trip home with the check engine light on. The car was only driven for about 300-400 miles in the time I had it. When I brought it to have an oil change, they found metal shavings in the oil. From what I’ve been reading, this has been a common problem for this vehicle. It has been sitting in a Hyundai service center for at least a month now with no real responses from Hyundai themselves. They told me they would not fix the problem due to lack of maintenance from prior owners and that they were marking my title (doesn’t make sense since I bought this with a clean title). According to what Hyundai told me, this issue was brought up by a previous owner in January 2026 with no repairs. How can you change the status of my title while refusing to repair a problem caused by a manufacturers defect?

The Hyundai Theta engine is a bad design that has many recalls, a history of oil consumptions, and breakdowns that leave consumers in danger, on the roadside, and out of money. This engine has a design that causes worn engine components and high oil consumption causing reduced engine power, ruined spark plugs, and engine damage with no recourse as a owner. Recently, my family member had a hesitation that causes the car to run rough and display a check engine light. She was in traffic and the vehicle was stopping. Had this been on the interstate it could have been deadly. This IS NOT UNCOMMON for these vehicles. A quick Google search is nationwide proof of an issue with these vehicles and engines that the government needs to hold Hyundai accountable. This particular vehicle has been assessed by a Hyundai and confirmed it is consuming oil at a higher rate than normal, as many other owners have documented. With this most recent issue of stalling out, the mechanic indicated that excessive oil consumption entering the spark plug port has fouled the spark plugs as the design of the engine is flawed. The oil consumption was discovered at approximately 99,000 miles and several steps were completed to "fix" and confirm the issue. There is no "real fix" to the issue due to the inherent design of the motor. Again, this is not a new issue with these cars and there should be recourse that holds Hyundai accountable for bad and dangerous engines. The check engine light did come on as the ve

The engine on this vehicle suffers from a severe oil consumption defect that was first officially reported to the authorized dealership on February 3, 2025 at approximately 90,000 miles while under the factory powertrain warranty. The vehicle completely empties its engine oil supply in under 1,000 miles of normal driving. Running entirely out of oil within such a short interval poses an imminent, extreme risk of sudden engine seizure, catastrophic mechanical failure, and sudden stalling at highway speeds. The manufacturer and dealership have physically documented this rapid depletion of oil over a 17-month period but are refusing to replace the defective components, instead attempting to force this unsafe vehicle back onto public roads for repetitive driving tests.

The car has 90,000 miles on it and uses excessive oil, not leaking. It uses at least one quart per 1000 miles.

Drive train, head gasket, burned valve, leaking

The contact owns a 2018 Hyundai Santa Fe Sport. While the contact’s daughter was driving approximately 10 MPH, the vehicle started bucking and shaking abnormally. The warning light indicating that the oil level was low had flashed on the screen. The driver pulled over to the side of the road and waited for the contact to arrive on scene. The contact inspected the vehicle and became aware that the oil level was extremely low. The contact added oil to the engine, and the dipstick failed to indicate the oil level until there was a quart full. The vehicle was taken to a certified mechanic, who diagnosed the vehicle with engine failure and referred the contact to the dealer. While attempting to drive the vehicle at approximately 20 MPH with the hazard light flashing on the highway, the vehicle lost drive power. The contact was able to coast to the side of the road and waited for the vehicle to be towed. The vehicle was towed to the dealer, but the vehicle was not diagnosed or repaired. The contact stated that the failure had occurred after consistent oil changes, and the next oil change was not due for 11 days. The manufacturer was not made aware of the failure. The failure mileage was approximately 75,314.

I had my engine replaced in Nov 2024 due to excessive oil consumption. I was required to do an emissions update due to a recall on my car. Once the dealer did the update, it caused my check engine light to come on and now I need a new catalytic converter, which was all due to the excessive oil consumption. Hyundai dealer knows this but they are telling me I’m responsible for replacing it. It should be replaced by Hyundai not me. It was the issue with the engine.

2018 Hyundai Santa Fe Sport. Purchased January 2026 took to Oxmoor Hyundai Service Center March 2026. February 2026 began using oil at a measured rate of 700 miles per tank of oil. Used 3 full tanks of oil within the month of February. Oil lights and engine lights on and off and flashing during this time. March 8, 2026, engine light flashed and then stayed on continuously. Engine shook and stuttered and made a loud noise. Engine stalled while I was driving at 35-40 miles per hour. I was able to continue driving to my home with the stuttering and stalling. The next morning I drove it to the Oxmoor Hyundai Service Center. I told relayed the timeline of all symptoms I had experienced over the 2 month lifetime of my ownership. They did not attempt to reproduce the issue. They only entered "shakes in reverse" as the customer provided issue on the intake information. Service Center performed diagnostic, found cylinder misfires on cylinder 2 and cylinder 4. Replaced spark plugs to resolve Cylinder 2. Cylinder 4 continued to misfire. Used Borescope and found broken valve. They did not address the scoring on the cylinder of the valve. Recommended engine replacement. Advised it would not be covered under a warranty because the rod did not break. The oil consumption was proven with documentation from multiple Valvoline visits and the vertical scoring was present on the cylinder with the broken valve in the borescope photo. The Service Center refused to do a Boring Clearance Test or any

TOOK CAR TO DEALER TO HAVE OIL CHANGED ON APRIL 29, 2026 AND WAS TOLD THEY HAD ALSO PREFORMED A SOFTWARE UPDATE, SERVICE CAMPAIGN 9C2. EVERYTIME SINCE THAT DAY AFTER THE CAR HAS SET FOR A LITTLE WHILE AND THE CAR IS RESTARTED DRIVEN IT STALLS AND SURGES REALLY BAD SEVERAL TIMES LASTING FOR SEVERAL MINUTES. IT ALSO CAN DO THIS AT RANDOM AT ANYTIME BUT NOT CONSTANT LIKE IT DOES WHEN FIRST STARTED. THIS IS VERY DANGEREST FOR OBVIOUS RASONS AND NEEDS TO BE FIXED. ALTHOUGH THERE IS OTHERS REPORTING THE SAME PROBLEMS ON LINE AND A PERSON MAKING THE SAME COMPLAINT WHILE I WAS WATING AT THE DEALERSHIP. THEY SAY "THEY ARE UNAWARE OF THE PROBLEM AND I WILL HAVE TO LEAVE MY CAR FOR UP TO THREE DAYS OR MORE TO HAVE IT CHECKED OUT AND THEN THEY WILL LET ME KNOW WHAT NEEDS TO BE DONE” AND WHAT THE COST WILL BE. I ONLY HAVE THE ONE VEHICLE AND THEY WOULD NOT PROVIDE A LOANER VEHICLE SO NEEDING MY CAR EVERY DAY I CAN NOT DO WITHOUT IT. DUE TO THE FACT THAT HYUNDAI REFUSES TO ACKNOWLAGE THE PROBLEM. THERE REALLY NEEDS TO BE A RECALL TO HAVE THIS PROBLEM FIXED.

The engine valves and cylinders keep failing every 6 months. I have to spend another $1,800 to get it fixed. I doe this TWO TIMES last year. My car has the Theta 2 engine

While driving on the highway at approximately 70 mph with a heavily loaded vehicle, my 2018 Hyundai Santa Fe Sport 2.4L suddenly lost power and entered limp mode. The check engine light flashed and diagnostic code P1326 was stored. During limp mode the engine was banging hard, almost like it was seizing and then releasing repeatedly. This is consistent with connecting rod bearing failure, not wrist pin failure. P1326 is generated by Hyundai's Knock Sensor Detection System (KSDS), specifically designed to detect abnormal vibration consistent with connecting rod bearing failure — a known defect covered under Hyundai's Theta II engine warranty extension. Prior to this event the engine had been consuming oil abnormally. Approximately 1,300 miles after my last oil change the oil level had already dropped to the low mark on the dipstick, a significant change from normal operation. The vehicle was towed to a Hyundai dealership where it remains today. The dealership confirmed cylinder scoring and wrist pin damage. Hyundai is attributing the failure solely to wrist pin failure to avoid Theta II warranty coverage. I believe the wrist pin damage is downstream damage caused by the underlying rod bearing defect. My safety was directly at risk at highway speed. The vehicle has approximately 140,000 miles and is within the 15 year/150,000 mile Theta II warranty extension. A Warranty Prior Approval has been submitted to Hyundai Motor America and has been unresolved since March 24, 2026.

My 2018 Hyundai Santa Fe Sport equipped with a Theta II GDI engine began exhibiting excessive oil consumption, engine knocking, and cylinder misfires consistent with the known Theta II engine defect covered under the Hyundai class action settlement. Prior to the failure, the check engine light illuminated and I experienced repeated misfires and audible engine knocking. The vehicle required frequent oil additions between oil changes due to excessive consumption. The vehicle was taken to an authorized Hyundai dealership where a diagnosis confirmed a burnt valve inside the cylinder head. The dealership recommends replacement of the cylinder head or complete engine replacement to correct the issue. The dealership performed a bearing failure test and attributed the burnt valve to carbon buildup. However, excessive oil consumption in a GDI engine directly accelerates carbon buildup on intake valves, as burning oil deposits carbon on valve surfaces preventing proper seating and causing overheating and valve failure. The carbon buildup is therefore a consequential result of the Theta II oil consumption defect, not an independent cause. The safety risk is significant as engine misfires and knocking while driving create unpredictable loss of power and potential for stalling in traffic. The vehicle is currently not reliably operable. The manufacturer has been contacted regarding coverage under the Theta II settlement. The component is available for inspection upon request at the servici

I was told by a mechanic that something electrical is wrong with the vehicle it causes the engine to misfire. Different issue than before.

The contact owns a 2018 Hyundai Santa Fe Sport. The contact stated that while driving 30 MPH and attempting to accelerate, the vehicle hesitated, with the check engine warning light illuminated. The vehicle was driven back to the residence. The vehicle was not repaired. The dealer was not notified of the failure. The manufacturer was not notified of the failure. The failure mileage was 141,654.

I own a 2018 Honda Santa Fe it is using oil so fast. I know that there is other people complaining about the oil consumption so my engine just blew up because I had it changed on March 13 brand new oil change and on Monday night the engine blew up.. The people who changed my oil said that there have been a complaint that they have been using so much oil and I have talked to Hyundai about this and they refuse to do anything Now I have a Hyundai Santa Fe that is no good to me because I personally can’t afford a new engine/motor

I bought a 2018 Hyundai Santa Fe from a dealership in May of 2023. Ever since then I have paid around $8,000 in repairs for this car. These repairs have been so expensive and time consuming that last year I wasn’t able to drive it for 6 months because it was in the shop for most of the year. I had to fix the Fuel pump, the Battery, timing chain valve TWICE, O2 sensor , Catalytic Converter, Engine valve, cylinder 1 & 3 and NOW I have to fix cylinder 2 & 4 & that cost again around $2,000 to fix. I am constantly stressed out, crying and becoming broke because I have to keep on repairing this car. I use up all of my tows every year because my car always shuts off on me while I am driving. I am at the point where I want a refund on the car and I want to get rid of this vehicle. I do not feel safe driving on the highway or driving with my two kids and I am currently pregnant again and this car isn’t safe for a family. I am constantly feeling broken down and worthless because I can’t even keep this car a float.

Enterprise car sales sold me this vehicle when it had 3 open recalls on it. The vehicle itself was a problem from the beginning. When I took it in for it's first oil change the mechanic told me it had no oil in it. He said they sold me a car that is notorious for consuming oil and or seizing or blowing up. I had the engine replaced on this car already and I just took it in for it's first oil change and it was already consuming oil. I want a new car but enterprise is telling me this is my problem

The contact owned a 2018 Hyundai Santa Fe. The contact’s son stated that while driving at 45 MPH, the brake pedal depressed with no warning light illuminated. The contact’s son stated that the ABS braking system failed, and the brake pedal did not function when attempting to stop the vehicle. As a result of the failure, the contact’s son collided with the highway pavement. No injuries were sustained, and no medical attention was required. The contact’s son also stated that the air bags did not deploy during the crash. A police report was filed. The vehicle was towed and was deemed a total loss by AAA due to severe front-end damage. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 130,000.

I drove 2.5 hours north to a Marine brother's father's funeral, who unexpectedly passed. I started my drive home and made it to Yorktown in about 15 minutes, and the engine light came on, started flashing, and went into limp mode. I pulled over on I-69 to shut it off, pulled the dipstick, and the oil level was full. I pushed the Bluelink button on my rearview mirror, and HMA sent a tow truck to tow the vehicle to a local dealership about 10-12 minutes away. The dealership did not inspect the vehicle until the following Monday, since it was Friday, three weeks ago. The dealership found DTC codes for misfires in cylinders 1 and 2, multiple-cylinder misfire, and too-high pressure in all four cylinders. The vehicle has had the knock sensor replaced, a KSDS ECM update, and a series of gaskets replaced. It has been burning oil since 69,362 miles and is now not operational, 2.5 hours from home. HMA has declined to replace the engine on a vehicle involved in a class action settlement due to problems with several completed replacements. The dealership has followed the manufacturer's process, and, due to the engine not producing a code it had at 87,986, but now not capable due to piston damage, cylinder scouring, and spark plug damage, the manufacturer has declined a goodwill replacement. The engine failure did put others in harm's way, as it did me when having to pull off the busy interstate to inspect the obvious failure. I have been driving a rental since this situation occurred, ha

The contact owned a 2018 Hyundai Santa Fe Sport. The contact stated that while driving 5 MPH, while depressing the brake pedal, the vehicle failed to respond. No warning lights illuminated. The contact pulls over to the right side of the road, exits the vehicle, and notices flames coming from the engine, and smoke starts coming inside the vehicle. The contact mentioned that a bystander gave him a fire extinguisher to extinguish the fire, the flames stopped, then a couple of seconds later, the failure persisted. No injuries were sustained. No medical attention was required. A police report was filed. The fire department extinguished the fire. The vehicle was destroyed. The vehicle was towed to J&J Towing. The vehicle was not repaired. The contact was relating to the failure of the NHTSA Campaign Number: 22V810000(SERVICE BRAKES, HYDRAULIC). The manufacturer was not notified of the failure. The failure mileage was 170,000.

I am reporting a serious safety concern involving a 2018 Hyundai Santa Fe Sport with approximately 132K miles. While driving at highway speed, the vehicle suddenly lost power/velocity and the engine light flashed. This created an immediate safety hazard, as maintaining speed is critical in highway traffic. Within seconds, the vehicle regained power and the warning light turned off, giving the impression that the issue had resolved. Shortly afterward, while exiting the highway, the vehicle began shaking and felt as though it would stall but was able to drive home less than one mile. A mechanic retrieved misfire codes for cylinders 2 and 4. Further inspection revealed internal engine damage in cylinder 4 requiring major rebuild. A full deconstruction revealed that one of the valves in cylinder 4 had partially broken. This failure occurred with little to no warning and involved a sudden loss of power at highway speed, which could have resulted in a serious accident. The vehicle’s warning systems did not provide adequate or persistent alerts prior to significant engine failure. Over the last 6 months it began consuming oil frequently requiring weekly checks, however no warning systems or errors to indicate an underlining concern. Based on research, similar Hyundai vehicles have documented issues involving excessive oil consumption and internal engine damage without sufficient warning. This raises concerns about a potential safety defect affecting engine performance and failure de

At 4 AM on March 10,2026, I received a recall for the tires (Recall ID:26T009). I took it to the Hyundai dealership to get it serviced. The Director Mr. [XXX] , informed me that the only recall they have for me is a software recall. In addition, the do not fix any tire recalls I would have to reach out to the manufacturer such as Kumho tires co. When the service tech [XXX] looked at the tires, he informed me that there is Bridgestone tires on the vehicle.

Took car to Valvoline oil change-they state no fluid on the oil dipstck. Scheduled oil change was not for another month. No oil leaks at all. Vehicle is bucking and knocking and loses acceleration. I have an appt at the dealer tomorrow3/2/26 and am hoping hyundai will cover any necessary repairs as they have multiple Technical service bulletins about this.

The contact owns a 2018 Hyundai Santa Fe Sport. The contact received an undisclosed recall notification, and the local dealer was contacted; however, there were no appointments available. On a separate occasion, while driving at an undisclosed speed, the vehicle jerked, and the check engine warning light illuminated. The vehicle was taken to an O'Reilly's Auto Parts to be diagnosed, and DTC: P1326 was retrieved. The vehicle was taken to the dealer and the contact was informed that there were damages to the engine caused by engine misfire. The dealer was in the process of determining if the engine needed to be replaced. The contact waited and then called the dealer and was informed that DTC: P1326 was not the correct code and that there was another fault code related to the recall. The contact was informed that the repair would be an out-of-pocket expense. The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 120,000.

The contact owns a 2018 Hyundai Santa Fe Sport. The contact stated that while driving at 55 MPH, the engine made a knocking sound, and the vehicle started shaking before starting to smoke. There was no warning light illuminated. The vehicle was towed to the dealer, who determined that there was a hole in the engine block and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact that since Service Campaign: 953 (ECM & Cluster Update) was not completed in a timely manner, the engine replacement was not covered. The contact had not received the notification for Service Campaign: 953 (ECM & Cluster Update) or owned the vehicle when the Service Campaign had started. The failure mileage was approximately 122,000.

Engine cut out on highway, check engine light flashing. Car would not exceed 50 mph on highway and would hesitate/jump trying to go up any hill/incline. Took to mechanic and vehicle had P1326 knock sensor code. There appears to be a service campaign (Campaign 966/T3G) for 2013-2018 Sanat Fe Sport vehicles, but when i enter my VIN campaign does not appear. This is a safety risk/hazard and should be covered by the campaign/addressed by dealer. Car has always been well maintained and adhere to service schedule.

While parked the panoramic sunroof spontaneously shattered.

My air bar light was flashing so I took it into the dealer as it is still under warranty. They said it is a sensor in the seat that deploys the air bag. It has been since November with no ETA on the part. When I asked about getting my car back after several times they tried to get me to sign a wavier saying if I was in an accident they wouldn't be liable. I refused and my car is still at this dealership.

My vehicle is using excessive oil. I first noticed this around 80 000 miles. Initially it started off with not being able to get the 5000 miles before next oil change and dropped to around 4000 miles. It then dropped to 3000 and now less than a 1000 miles before I am needing at least 2 quarts of oil. I have had the vehicle examined by midas and they confirmed there are no leaks, cracks or reason for the excessive oil consumption. They suggested that I contact the dealer as this is a known issue and to get help with replacing the engine. I contacted the dealership and was told I would get a call back and never did. I also contacted hyundai on their website and put in a complaint and requested the engine be replaced, with no response from that as well.

Car stuttered and would not rev past 2k rpm. Blinking check engine light appeared Code was for known connecting rod failure for all theta engines for our 2018 sante fe. Hyundai is trying to get out of covering the cost of repair or replacement even though this is a very well known issue and is covered under warranty.

Constantly losing oil and there is NO oil leak. Had numerous Oil Consumption Test done. Paid for other unnecessary testing as well. Thousand of complaints on line of other Santa Fe Sports also having the same issue. Hyundai denied a new engine even though dealership recommended it. Also Hyundai Consumer also denied, since corporate told dealership no. Losing 4 quarts of oil, going less than 1000 miles. Let it sit for over a month, then took it back. Now they said I was 2 quarts over. It has the dealership tamper seals on it. Only dealership has been adding oil. Customer Service representative, accused me of adding oil. I asked how do you think I did that? Your Seals are on my car that your dealership out on there. Said it needed an oil change since it was over. Told him that's fine, but I was not paying for it, since they were the only one who out the oil in. So now I am having to do yet another oil consumption test. This was on 2.3.26

Engine consumes excessive amounts of oil. we have to check oil every day and add oil even after 30 mile trips. low oil can result in a seized engine which could result in a crash if power is lost in high traffic areas or highway speeds. hyundai knows there is an issue and engines that seize are replaced with the same defective design. this is dangerous and could result in a crash or being stranded in an unsafe area

My starter failed while out shopping. No issues starting the car departing from my home, but would not start in the store parking lot. My mechanic did not provide the broken part for inspection however everyone commented that is was very unusual for it to fail as I only have roughly 25,000 miles on it. My mechanic also mentioned that this was 2nd 2018 hyundai sante fe in the past week he had to replace the starter on that vehicle had 60,000 miles. There were no warning lights prior to the event, I suspected it was the starter after having a new battery installed and no success starting because of the lights that remained on on the instrument panel.

My vehicle has approximately 152,000 miles, and I am currently experiencing a major engine failure. Oil consumption and knocking on engine Hyundai has had lawsuits in the past with unsafe unreliable engines.

The contact owns a 2018 Hyundai Santa Fe Sport. The contact stated that the headlights suddenly illuminated without the vehicle being turned on, causing the battery to be drained. The contact recharged the battery to start the vehicle. The contact stated that the light switch failed to turn off the high beam headlights; however, the headlights and the indicators were no longer illuminated. The vehicle was towed to the dealer, who stated that the junction block had failed and needed to be replaced; however, the contact was not sure of the cause of the failure and needed to repair the vehicle. The dealer diagnosed the vehicle that an interlock casing, fuse, and relay that had melted, and that the switches were not responding, but could not confirm what caused the failure. The contact learned that the vehicle was previously included in a recall for another junction box that had been repaired. The contact was unable to provide the recall campaign. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 18,000.

Engine is burning oil as a default in manufacturing of engine, leaving little to know oil in the engine and causing other malfunctions that use the oil

The contact owns a 2018 Hyundai Santa Fe Sport. The contact stated that while driving at 25 MPH and approaching a stop, the vehicle stalled. The battery, check engine, and oil warning lights were illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 22V810000 (Service Brakes, Hydraulic). The vehicle was towed to the local dealer, where an unknown diagnosis was provided. The vehicle was not repaired. The warranty claim was denied. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 160,000.

The vehicle developed loud engine knocking and abnormal noise consistent with known Hyundai engine defects. The vehicle is unsafe to operate and has been retained at an authorized Hyundai dealership since October 25, 2025. Hyundai vehicles with similar engine failures have been documented to catch fire, including while parked. Despite the known defect pattern, the manufacturer is refusing warranty coverage, alleging lack of complete oil change records, without providing proof that maintenance caused the failure. This represents a serious safety risk to occupants and the public. My family includes a child with a motor disability, which significantly increases the danger in the event of fire or engine failure.

I have been experiencing issues with oil consumption, having to get oil changes every 2 months and sometimes monthly with no reported leaks from 2 different mechanics. I have been very high maintenance over my oil. While I was driving on the highway, my vehicle began to shake and a knocking sound was heard. I felt the vehicle begin to jerk but no warning lights were on. I was no longer able to drive and had to pull over and wait for a tow to my mechanic's garage. The mechanic let me know there was an issue with the engine, specifically the 3rd cylinder and the piston. It does not put out as much pressure as it is supposed to. I brought the vehicle to the dealership after and they confirmed this was an issue and quoted me $8700 in repairs. There were no warning lights and no engine lights prior to this happening. I was informed by my mechanic that this is a known issue with Hyundai in their 2018 models having failing engines. I purchased the vehicle certified pre-owned with a guarantee from the dealership that I was purchasing a reliable vehicle that should have no issues of this degree.

Engine burns prodigious amounts of oil. Uses one quart in about 400 miles. Hyundai verified this with their 1000 mile oil consumption test. The only reason that this engine did not spin the crankshaft bearings from running dry on oil is because I was so diligent in filling the crankcase. A service writer at Happy Hyundai said that I needed a new long block, but the dealership refused because I had 103,000 miles on the engine. They knew about the problems with oil burning on Theta engines, but were happy to send me on my way knowing that I would be putting oil in my car often. This is not acceptable. Can you help me?

This engine is burning oil. Its mixing oil with gasoline in the cylinders. Its fouling spark plugs and consuming large amounts of oil with absolutely no visible oil leaks. The exhaust is black. PCV valve is clean. Engine is misfiring due to spark plug fouling. New spark plugs and coils. Multiple dealers have stated this is a KNOWN defect with this particular GDI engine but Hyundai refuses to issue a recall.

I recently purchased this used vehicle in June(2025) and after a couple of months of owning the vehicle, I started noticing the car oil level when I checked, started being lower than normal pretty frequently. And it has gotten to the point where I would have to top the oil off every week only after driving a few 100 miles. When I went for my oil change this October, I did informed Hyundai about the issue and they told me to drive the vehicle for 900 miles, do not top it off. And I am following what they're saying, and right now, I just checked my oil, and I have only driven it for 468 miles since I had gotten it changed on October 22nd of this year, and it's showing about a 1/2 quart low at the dipstick already. But if it gets too low before the 900 miles, I would take it to Hyundai so as not to cause any damage to the engine driving it with the oil too low if it gets to that point. The service tech did state that the first step in correcting the issue was to do a combustion flush. And I hope that Hyundai is taking care of the issue for us consumers. I appreciate your prompt response regarding this matter. Thank you. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I'm the second owner of this vehicle, I purchased it when it was one year old. I've provided careful maintenance, as this is my only vehicle. In the last year+ it started burning more and more oil. I was told by a mechanic that there were no signs of leakage and that these engines tend to burn a lot of oil so I was very careful to monitor levels and up the oil changes. 6 months ago, it was in the shop for new brakes and had a complete diagnostic exam and there were no issues with the engine. Two weeks ago, before a road trip, I again had full diagnostics done on the vehicle and there were no codes that popped up. The vehicle died on my trip. Reading the codes, I received my first code regarding problems with my cylinders after the vehicle died. Now I need a completely new engine because cylinders 1 and 3 failed. The car only has 80,000 miles on it. In all my years of my family owning different vehicles, I've always owned vehicles until they were well over 100,000 miles. The only two vehicles owned by my family that ever needed engine replacement early in their lives were both Hyundai vehicles. After I was told that I needed a new engine at 80,000 miles, I was told that this was not due to the one specific problem Hyundai would cover so I have to pay to replace it myself. There are a plethora of forums, mechanic experiences, etc, that show these 2.4L engines have this exact problem, but Hyundai washes their hands of us. As a second owner, I don't qualify for the engine warrant

The contact owns a 2018 Hyundai Santa Fe Sport. The contact stated that while driving to the residence at a moderate speed, the oil warning light illuminated on the instrument panel. The following day, the vehicle was taken to an independent mechanic, and the contact was informed that there was no oil in the engine even though an oil change had been performed a month earlier. The vehicle was taken to another independent mechanic, where an oil change was performed. After the oil change, the contact stated there was an abnormal knocking sound coming from the engine while driving at various speeds. The contact then stated that while at a stop light, the engine seized while depressing the accelerator pedal, with several unknown warning lights illuminated on the instrument panel. Due to the failure, the vehicle was towed to the dealer, and the contact was informed that the crankshaft rod was defective. The dealer linked the failure to Hyundai recall 953; however, the contact was later informed that since the vehicle was not serviced for a prior knock sensor recall, the vehicle no longer qualified for the repair. The vehicle was not repaired. The manufacturer was also notified of the failure, and the contact was provided a case number. The contact was later informed by the manufacturer that the vehicle would not be serviced under warranty. The contact stated that the recall was placed on the vehicle prior to owning the vehicle. The failure mileage was approximately 149,000.
