general problems of the 2017 Hyundai Santa Fe - part 2

My 2017 Hyundai Santa Fe sport 2. 0t (theta ii 2. 0l gdi turbo engine) has been diagnosed with burned exhaust valves requiring a complete engine replacement. This is the second catastrophic powertrain failure on this vehicle in under two years. In July 2024, I paid $2,754 to replace the turbocharger at an authorized Hyundai dealership (wright Hyundai, [xxx] ). The burned valves are consistent with carbon buildup on intake valves, a widely documented and known deficiency of the gdi fuel delivery system used in the theta ii engine family. Carbon deposits restrict airflow, cause valve seating issues, and lead to valve failure. This is an inherent design characteristic of the engine, not a maintenance-related failure. At no point during my ownership — including during the turbocharger repair — was I informed of this known issue or advised of any preventive measures such as fuel system cleaning treatments. I am additionally concerned that the dealership's diagnostic process was incomplete. The service center diagnosed the burned valves and immediately recommended an engine replacement without performing a bearing clearance test or completing the full diagnostic flowchart. The dealership has refused to perform further diagnostics unless I pay additional fees, and has refused to share documentation from a tech line case opened with Hyundai corporate. Because diagnostics were halted at the burned valve finding, a connecting rod bearing failure — the specific defect covered under the theta ii class action settlement (in Hyundai and kia engine litigation, noxxx) — has not been ruled out as a contributing cause. Hyundai's national consumer affairs office (case #xxx) denied my goodwill request without addressing either the known gdi carbon buildup issue or the fact that this is the second catastrophic failure on this engine platform. This vehicle has approximately 86,000 miles. I purchased it as a second owner in August 2020 at 42,730 miles. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 5.

Hello, I was driving home from work with my six-month old in the car and the engine stalled while on the belleville turnpike. It seized and I was almost rear-ended by a tractor trailer hauling lumber to the lumber yard just a few streets away. I couldn't move the car and was afraid of how to even attempt to secure my car as my daughter was strapped in her car seat. An extremely nice man pulled over and began to flag vehicle to go around me. By this time, I had only my hazard lights on. I was frightened beyond belief having gone through that experience. The car was towed to the dealership who confirmed it was catastrophic engine failure(misfire of a cylinder). They stated initially with my 3rd party warrant that it would be covered and in their words " it was a good thing I had a warranty". Fast forward to two weeks after I check to see what is going on. Things have changed. Now, because I am missing one oil change receipt, they need to be paid $1400, to further corroborate the cause of the engine failure. I haven't paid and honestly don't plan on paying them anything. To date, I have spent over $2,000 on car rental fees since my car is now sitting at the global Hyundai dealership.

Engine failed at approximately 95000 miles.

Purchased this 2017 Hyundai Santa Fe from dealer with 86k miles. (second owner). Immediately noticed excessive oil consumption. Would take vehicle in for oil top off service, to ensure proper levels. At 99k miles (six months after purchase) lost compression in #2 cylinder while driving on the freeway. Per independent auto repair facility and a Hyundai service center, engine replacement is needed. Hyundai declined engine replacement. It appears oil consumption was an issue when the vehicle was traded in to the dealership, and they resold it anyway to an unsuspecting consumer.

My vehicle was serviced for an oil change at my dealership today. The mechanics are concerned about too much oil consumption in between oil changes. They have no evidence of a leak. Prior to getting my oil changed, a red oil light appeared when I brake. The dealership had mentioned of related recalls for this problem for this vehicle model.

We have a 2017 Hyundai Santa Fe with 130k miles on it. It has the 2. 4 engine with known manufacturing defects. We are the 2nd owner and timely & proper maintenance was completed on it since it was new. My [xxx] driver was operating the vehicle on interstate 75 in middle georgia when the vehicle started running very rough, slowed down dramatically and the check engine light started blinking. She was blessed that a large truck didn’t run her over as she tried to move to the side of the roadway. We called a tow truck to take it to the nearest Hyundai dealership- alm Hyundai of warner robins, GA. They inspected the vehicle and stated that the engine had messed up and they wouldn’t replace it since the vehicle had 130k miles and outside their window for 120k mile replacement. We purchased the vehicle from the original owner in 2022. We verified that it had timely and proper maintenance on it. We were also aware of a potential engine issue but verified with a Hyundai service advisor at five star Hyundai in macon, GA that the vehicle would be eligible for engine replacement if it messed up due to a manufacturing defect as long as proper maintenance was completed. We noticed that the vehicle was significantly burning oil at around 110k miles and regularly had to put oil in it to make sure it would not run dry. We did have the safety recall performed on it for the engine knock issue that Hyundai mandated. These vehicles are a major safety hazard on the roadway and these effected engines should be replaced by the manufacturer. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Component: engine (theta ii 2. 4l gdi) / connecting rod bearing-related failure risk with abnormal internal oil loss. The vehicle is available for inspection upon request (engine, oil level condition, diagnostic history, and dealer records). Safety risk: while driving on the highway (approx. 70 mph), the vehicle displayed a low oil warning, and I experienced concern for potential engine seizure/stalling and sudden loss of power, which could cause a crash. I reduced speed and sought service. This condition presents an ongoing safety risk because sudden engine failure can occur without adequate warning. Dealer confirmation: the problem was confirmed by a Hyundai dealer. After a routine oil change, the low oil warning appeared within ~1,700 miles. A Hyundai service center inspected the vehicle and documented the engine was approximately 3 quarts low with no external leaks, indicating internal loss/engine deterioration rather than a leak. Hyundai then required additional steps (combustion chamber cleaning and monitored mileage), and the abnormal internal oil loss condition persisted. Manufacturer inspection: the vehicle has been inspected by Hyundai dealerships, and Hyundai performed campaign-related actions, including ksds/ecm update (t3g) and later knock sensor replacement. No police or insurance inspection. No crash or injury occurred. Warning lamps/symptoms prior to failure: prior symptoms included a check engine lamp with dtc p1326 (ksds-related) documented by Hyundai service in 2025, followed by continued abnormal internal engine condition. The low oil warning occurred while the vehicle was in motion (highway speed). The issue remains unresolved, and I do not feel the vehicle is safe to operate due to seizure/stall risk. Additional: I reported this as a safety defect because similar theta ii engine issues are widely reported and can result in stalling, seizure, or engine fire. Hyundai denied engine replacement assistance despite the documented condition.

This is an update to existing NHTSA odi complaint #11735718 2017 Hyundai Santa Fe sport, txxi theta ii engine defect. Update: on may 7, 2026, Hyundai case manager acknowledged in writing "your case is important to us" and "2. 4l theta concerns" for case #42623761. This is written admission the vehicle has the txxi defect covered by warranty extension to 120,000 miles. I gave Hyundai 48 hours to provide written authorization for oil consumption test per their TSB 22-em-003h. After 3 days they are silent. They refuse email communication despite documented language barrier. Current vehicle status: - active dtc p0010 causing loss of power and stalling risk - oil consumption: 1 liter per 600km, which is 3x Hyundai failure threshold in TSB 22-em-003h - 95,772 miles, under txxi 120,000 mile warranty limit - u. S. Spec vehicle covered by txxi warranty extension Hyundai is violating magnuson-moss warranty act by refusing to honor written warranty for known safety defect. The p0010 defect causes sudden loss of power while driving. Requesting immediate NHTSA intervention to compel Hyundai to perform warranty repair.

I currently owned an 2017 Hyundai Santa Fe fwd with the 3. 3 v6 engine with approximately about 136,000 miles. We were driving into vegas when we heard the knocking engine sounds. Immediately we called the dealership in vegas advising them we were going to tow the vehicle in. Once we get the vehicle towed over to the dealership, we waited till the following Monday where it was authorized to have the engine replaced. We were so glad about that. The vehicle was going to be completed by early January and we got the news the vehicle was completed but now having misfiring issues due to faulty injectors. I was advised that this was not covered due to the mileage. This was an non issue when I turned in the vehicle to Hyundai. I made several attempts to contact my case manager and this was again denied due to the mileage. For a vehicle with less than 140k miles and being less than 10 years old, we are very upset with this process and for Hyundai knowing that there were concerning issues with both the fuel injectors and engine.

I have a 2017 Hyundai Santa Fe with ~88,000 miles. I noticed on 12/18/2025 that the oil lamp light came on briefly then turned off. So, I decided to take my car in to get serviced on 12/19/2025. I was told that there is an oil consumption issue with the engine and that Hyundai would need to do a combustion cleaning, and worst case scenario a full engine replacement. Hyundai refuses to cover us under warranty because we transferred the car from my mother-in-law's name to my wife's name. I want to file this as a complaint to the NHTSA because a car that isn't even 10-years old and has less than 90,000 miles should not be needing an engine replacement. Hyundai appears to be aware of the issue as my service advisor at the dealership has mentioned that several of their cars with this engine have the exact same issue. To me, this sounds like a defect and should have a recall.

While driving- in total movement- the car completely shut off. Without any prior warning or indication. Immediately after, the car restarted, drove a couple blocks over, continuing to shut off while driving. It was then towed. How was your safety or the safety of others put at risk? the warning lights did not appear until after the car quit. They all came on & flashed & quickly went back out. Uncertain which component misfired or is affected- possibly related to an engine or fuel/ cylinder failure. Car is at mechanic for inspection. Our safety & lives were in critical jeopardy as the vehicle stopped without warning while driving in traffic congested area. It is unknown if this is a known issue or if this situation has been replicated however the current mechanic facility has experienced the same issue with this vehicle. Also strong odor of gas was experienced during shutoff.

The engine on my 2017 Hyundai Santa Fe sport was deemed defective according to downey Hyundai. They ran a diagnostic test on it and it failed the test. They offered to replace it for me at no cost to me. On December 11, 2025 the engine caught fire while the service technician from downey Hyundai was “test driving” it in a drive-thru of 7 leaves. He was using my vehicle for personal use when the engine fire occurred. Both downey police dept and downey fire dept made reports. I did file a claim with my insurance company, aaa. On 12/8/25, the engine oil light blinked once very quickly on the dash and that was it. I took my vehicle to downey Hyundai the very next day to have it inspected.

The contact owns a 2017 Hyundai Santa Fe. The contact stated that the vehicle was consuming an excessive amount of engine oil after approximately 1,500 miles, 2 weeks after an oil change was performed. While driving at various speeds, the vehicle was sluggish while attempting to accelerate. The check engine warning light has been illuminated since purchasing the vehicle. The vehicle was taken to a certified mechanic, who diagnosed the vehicle with turbocharger failure. The contact was informed that the turbocharger needed to be replaced. There was no oil found on the dipstick when the oil level was checked. The dealer was contacted and informed of the failure. The dealer determined that an oil consumption test was needed. Additionally, a cleaning of the oil system and an oil change were recommended. The vehicle was not repaired because it was not under recall. The manufacturer was informed of the failure and informed the contact that the vehicle needed to be diagnosed to determine the cause of the failure. The failure mileage was approximately 85,000.

Check engine light came on oil light came on then the vehicle shut off while I was driving. Safety was not good as I was driving the vehicle. I then had it towed to a shop to have it looked at. That is when I was told I would need a new motor due to a crankshaft failure. The check engine light had come on the night before but when turning the vehicle on the next morning to take it to get looked at it was no longer on. Was driving it too the shop to have it looked at when it shut off on me while driving.

The engine of our 2017 Hyundai Santa Fe sport has been significantly problematic since we first purchased the vehicle in 2017. These issues have been well documented by other Hyundai owners and have resulted in class action lawsuits. After purchasing our vehicle new from dealer, it began experiencing difficulties, consuming large amounts of oil, spewing smoke from the tailpipe, leaving metal shavings in the engine oil, failing to start, and at times going into a protection mode to keep the engine from further damage and restrict speed above 15 miles per hour. The vehicle had to be towed multiple times at our own expense. Hyundai delayed replacement of the engine for months resulting in thousands of additional miles being put on the vehicle under unsafe operating conditions. Hyundai reluctantly replaced the engine in February of 2024. What appears to not be well-documented in NHTSA complaints are the impacts of these engine issues to other Hyundai components and parts. Hyundai replaced our original engine but did not replace the engine’s catalytic converter. 20 months later, the check engine light has illuminated again as a direct result of oil sludge and buildup from accelerated oil consumption. In November 2025, the dealership identified the fault code p0420 for catalyst efficiency system below threshold. We have experienced a loss of acceleration, increased fumes, and decreased fuel efficiency as a result of the catalytic converter failure, and believe the vehicle is no longer safe to drive at high speeds on freeways. The dealership has confirmed damage to the catalytic converter and has quoted a replacement fee that is $5000, almost $1000 higher than other dealerships in our area. We asked for the dealership to submit a request to hma for goodwill assistance and were denied on November 24th. We strongly believe that Hyundai is responsible for both the damage to the catalytic converter as well as the safety concerns caused by this issue.

My 2017 Hyundai Santa Fe suffered a crankshaft/bearing failure identical to NHTSA recall 17v578000. Hyundai states my VIN was not included in the recall, but the vehicle has the same 3. 3l engine, the same failure, and the same symptoms described in the recall bulletin. The engine has never been replaced. The defect appears broader than the recall VIN range. They are refusing to replace the defective engine.

The vehicle’s engine is experiencing excessive internal oil consumption that poses a serious safety risk while driving. After a routine oil change performed by an authorized Hyundai dealer, the engine oil warning light illuminated within about 1,700 miles. Upon inspection by another Hyundai service center, technicians confirmed that the engine was burning oil abnormally and was three quarts low, with no external leaks. This issue was documented in the dealer’s repair order, which states “vehicle is burning excessive oil. ” the problem has been reproduced and confirmed by a Hyundai dealer. The vehicle is equipped with the theta ii 2. 4l gdi engine, which is already covered under Hyundai’s ksds (knock sensor detection system) extended engine warranty due to known internal mechanical defects such as bearing wear and oil consumption. Despite this, the manufacturer has declined to replace the engine. The excessive oil burning occurs rapidly and triggers the low-oil warning light while the vehicle is in motion, creating a risk of engine seizure and sudden loss of power that could lead to a crash. The defect remains unresolved. Warning lights for low oil level appeared multiple times beginning in 2025, shortly after the ksds update and knock-sensor replacement.

At 70,000 miles the Santa Fe was consuming oil at 1. 5 quarts per 1000 miles. It is a 2. 4 engine. The Hyundai dealership did an oil consumption test and verified the consumption. They want to do a combustion chamber cleaning and have me run it 1000 miles. The vehicle is unsafe because this defective engine could seize up at any time. I am trying to have Hyundai USA replace the engine ASAP. I have all my maintenance records and two warranties.

My 2017 Hyundai Santa Fe experienced a sudden and complete engine failure without any warning signs. There were no warning lights, no check engine light, and no unusual noise before the failure. The engine stalled while trying to start, ran very rough for a second, and then completely shut off. After that, the engine would not start again at all. A certified independent mechanic inspected the vehicle and confirmed the engine suffered a mechanical failure consistent with rod bearing wear or crankshaft damage, which is the same issue described in Hyundai’s known engine safety recalls. I later took the vehicle to a Hyundai dealership. They also confirmed that the engine had failed, but said it could not be repaired under Hyundai’s programs because my vehicle was not listed in the specific recall. I was never notified of any safety campaigns or recalls. I am not the first owner, so the required recall inspections and updates were never completed on this vehicle before I bought it. The sudden engine shutdown created a serious safety risk, especially because there was no warning before it failed. This failure matches the symptoms described in Hyundai’s theta ii engine defect investigations. I am requesting that NHTSA investigate whether this vehicle should be included in the affected group, and whether this engine failure is part of the broader safety defect already identified in many Hyundai engines from the same model years.

The light for the passenger airbag has been on for years. I have taken it in, and the only thing the service department determined is that there was a water bottle under the seat. I was rear-ended into another vehicle, and the airbag did not deploy. The engine burns the oil from an oil change in approximately two weeks. I add a quart of oil every two weeks. If the engine seizes while driving due to this condition, I could be injured in an accident.

It sounds like the rod inside are hitting need a new engine. Auto shop said need a new engine. Engine has 125000 that all no oil leak no other problems.

Engine went into limp mode and a knocking sound was heard. Had car inspected and oil changed but no improvements occurred. Took car to dealership and it failed engine test. Hyundai will not cover replacement under open extended warranty.

While driving on the highway at normal speed, the vehicle suddenly lost power with no prior warning lamps or messages, placing me and other road users at immediate risk. The engine rapidly began knocking, lost acceleration, then stalled completely. I had to coast to the shoulder, which was extremely dangerous in high-speed traffic. The failure appears consistent with bearing wear and debris circulation described in Hyundai recall 168 and TSB 17-01-071, which warn that certain Hyundai 3. 3l engines can suffer internal metallic debris contamination during manufacturing. This can restrict oil flow, damage the bearings, and lead to sudden engine seizure without warning — exactly what happened in this incident. After the failure, the engine was inspected by a Hyundai dealership, but no oil sample, no debris test, and no photo documentation were provided, even though the recall procedure requires these steps when symptoms match knock/no-start failure patterns. The cause was not reproduced or confirmed by any independent mechanical test; the vehicle simply failed suddenly and has remained inoperable since. The incident created a major safety risk because the sudden loss of power happened at highway speed with no safe way to maintain vehicle control or speed. Based on known recall documentation, the symptoms match the described safety-related engine defect. The vehicle remains available for inspection. There were no injuries or police reports, but the situation definitely could have resulted in a crash. In my assessment, this is a critical safety defect related to internal engine debris and bearing failure, consistent with the known Hyundai recall pattern for this engine family.

The contact's mother owns a 2017 Hyundai Santa Fe sport. The contact stated that while the owner was driving the vehicle at an undisclosed speed, the vehicle stalled. No warning lights were illuminated. The contact stated that the vehicle failed to restart. The vehicle was towed to the dealer, where it was diagnosed with loss of compression in the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. Additionally, the contact stated that the engine failure was a known failure. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 114,000.

The contact owns a 2017 Hyundai Santa Fe. The contact stated that the vehicle was consuming engine oil, and there was no indication of an oil leak. While a friend was driving, the vehicle stalled. The vehicle was pushed to the side of the road. The next day, while driving at unknown speeds with the hazard lights activated, the vehicle began making an abnormal sound and then stalled. The tpms and abs warning lights were illuminated. The contact stated that the failure was related to technical service bulletin number: 17-01-047-1. The vehicle was towed to the local dealer, where it was diagnosed with engine failure. The dealer submitted a claim. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 140,000.

My vehicle has never missed an oil change or maintenance event yet at my last oil change my engine had burned through all its oil and no low oil light or check engine light came on. Hyundai is refusing to cover it under their warranty stating it occurred due to maintenance neglect even though all oil changes and maintenance events receipts were provided to Hyundai and are available in car fax.

Engine is experiencing excessive oil consumption. Engine in question is a theta ii 2. 4 gdi. Losing a qt every 400-500 miles. The car has less than 75,000 miles on it. The vehicle has been religiously maintained, oil changes every 5,000 miles or less. However because we are the second owners, even though it was purchased in 2020 when it had less than 30,000 miles, the warranty does not apply. The engine type has several manufacturer defects. Hyundai is using the technicality of a non-transferable warranty to get out of the fact that they knowingly put a defective engine in vehicles. By the time the oil consumption issue is apparent, it is too late, and you need a full unit replacement. I was quoted $9,000 - $10,500 by two Hyundai dealerships to replace the engine. I've spoken to non-Hyundai shops and the only way to truly correct the issue is to replace the engine with a remanned engine since the actual engines are manufactured poorly from go, so even a new one could be defective. There are million of these engines across several kia and Hyundai vehicles. They cause undue burden to consumers. Hyundai and kia do not stand by their product and consumers are being hurt. Instead of having an asset I thought was worth $10,000 an I could drive for several years and tens of thousands, if not one hundred thousand plus, more miles, I have a vehicle that is a ticking time bomb that would cost as much to fully fix the problem as it is worth. A simple google for kia optima, kia sorento, kia sportage, Hyundai sante fe, Hyundai sante fe sport, Hyundai sonata or Hyundai tucson + theta ii 2. 4 gdi will yield more than enough results to show how prevalent the engine failure + oil consumption issue is. If left unfixed the engine will consume too much oil and seize, or lead to other problems with vehicle rendering unsafe to drive.

Documented oil-consumption issue with my 2017 Hyundai Santa Fe, which currently has 98,876 miles. This concern was first formally reported in October 2025. Since that time, I have fully complied with all diagnostic and procedural requirements requested by the dealership, including inspections, documentation, and follow-up visits. The dealership has acknowledged that the vehicle has an ongoing oil-consumption condition. Per the instructions provided by Hyundai service team, I was advised to “submit my own claim. ” I later learned that, as a customer, I am not permitted to submit or appeal a claim directly, and that only the dealership has the ability to do so. I have since been informed by customer care that the claim submitted on my behalf was considered weak, which may have contributed to its denial. I was also advised that Hyundai and the dealership were already aware that I did not have the ability to submit or appeal the claim myself, despite being directed to do so. Throughout this process, I have made every good-faith effort to follow Hyundai’s guidance, yet I have experienced repeated misdirection and inconsistent information. This has caused unnecessary delays and frustration while the underlying issue remains unresolved. The vehicle has been properly maintained, with regular oil changes and servicing completed according to Hyundai’s recommended intervals. Despite this, the excessive oil consumption persists and poses a risk to engine longevity and overall safety. Due to the current condition of the engine, I no longer feel it is safe to continue driving the vehicle, which has left me without reliable transportation. Additionally, I have previously experienced the theft of this vehicle, for which I was not compensated, despite the well-documented safety concerns affecting Hyundai customers. Taken together, these issues have significantly impacted my confidence and ability to rely on this vehicle. Given Hyundai’s well-documented history of oil-consumptio.

On [xxx], around [xxx] I was driving my car on [xxx] and I suddenly experienced "check engine flashing" and engine misfiring. I was driving ~70-75 mph in the left lane. I immediately turned on the hazard lights and somehow manage to get to the right lane and safely stopped the car in open space on the side. This could have resulted in a very serious accident as I had my whole family in the car with me. Hyundai motor company must be held accountable for this type of engine quality issue. My car has 119580 miles. I had always car maintenance done at Hyundai dealerships to make sure that it is maintained as per the company recommended. The catalytic converter in my car was changed by the Hyundai dealership (key Hyundai manchester, CT) at approximately 96000 miles as it had gone bad in April of 2024. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Engine failure with no prior warning, such as oil pressure gauge,oil indicator light, or check engine light. Vehicle was at dealership for maintenance and this happened as tech was test driving. Found all oil was lost with no indications of a leak.

On [xxx, I was driving on the interstate when my engine seized and the car lost all power, leaving me stranded on the side of the road on a busy exit at night. This was very dangerous to myself and others. I purchased this car in July of 2023 with 69,000 miles in good condition. I immediately made an appointment to take care of the recalls and updates to this car, which were performed February 2024 due to this being the first available appointment. Also, at my first oil change (3,000 miles after the previous oil change) I was told by the mechanic that there was absolutely no oil in my car. Since then I have had to put several quarts of oil in between each oil change, costing me hundreds of dollars. Then June of 2024, the p1326 code flashed on my car and it went into limp mode also while I was driving on a busy street, putting myself and others in danger. I took it to the dealership and was advised to continue driving it and there was nothing they can do until my engine fails. I also brought up the oil consumption issue and was told that even if I did an oil consumption test (at my cost), there was nothing they could do. I was advised by my service advisor not to do a consumption test. I took his advice and continued to drive my car, adding countless quarts of oil weekly to my car. Fast forward to September 2024, when my engine light came on due to misfires in cylinder 3&4 and I took it to a local mechanic due to the incredibly long wait for an appointment at Hyundai. I was told all 4 spark plugs were oil fouled due to excessive oil consumption. This happened again July of 2025. My mechanic advised me that there was nothing to do about it, but that this would continue to happen due to the oil consumption issue. Now Hyundai is refusing to take responsibility for this engine that has had documented issues resulting in class action lawsuits and safety issues for myself and others and refusing any financial assistance. No warning lamps were on before incident. Information redacted pursuant to the freedom of informatio.

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 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.
