Abs, traction control lights, emergency braking lights on .. tire sensors are bad. Causing intermittent issue with the lights. For 3 years I've been trying to get my ABS/traction control fixed at Hyundai, that dealership refused to acknowledge there was an issue. I had a code from a car place since I live over an hour away and they said they couldn't use it since it wasn't from them. I have an extended warranty there. Went to another dealership and was immediately told it was the tire sensors. That he used to work at the other dealership and they saw it all the time. I now see Palisades have a tire sensor issue. Heck I've been dealing with this for years, and apparently so are many other Hyundai owners, according to this Hyundai employee. Now they're trying to overcharge me and saying my warranty will only cover a quarter of what they want. My deductible is only 100 if I don't get the work done at the original place, the one that said there isn't a problem. I've had it with Hyundai. They are unsafe and don't care about customer service.
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.
Fire
While driving on US-rt1 in Dinwiddie Va, in my 2017 Hyundai Santa Fe Sport. I was in a collision where a vehicle pulled out in front of me at no fault of my own, and I hit that vehicle going about 47mph. the front nor rear/side air bags deployed. My body slammed into the steering wheel causing severe whiplash as well and contusions to my left shoulder and neck, as well as my wife to be who also sustained injuries to her leg/knee. Had the airbags deployed i would have not made contact with the steering wheel though-out these events.
Crash
1 injured
Car is running out of oil quickly but there are no visible leaks. Have had the oil changed a couple of times since then and have had to add oil in between because the oil light comes on when I make turns. Had the oil changed at a local oil service station and they said it was almost empty.
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.

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.
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.

I have maintained my car regularly. I use LOFSYNBLEND oil at 7500 mile intervals per car and oil manufacturer. At 70000 mile oil change the tech showed me that less than a quart of oil came out of the crankcase during the oil change. There were no visible leaks, no visible smoke coming out of the exhaust when I drove the car, and NO warning light. This was the first time that this issue was present to my knowledge. I am taking the vehicle to the dealer for an Official Oil Consumption Test.
Vehicle: 2017 Hyundai Santa Fe Mileage at Failure: ~129,000 miles Issue Type: Engine Failure / Valve / PCV-Related Defect Manufacturer & Dealer Both Denied Repair My 2017 Hyundai Santa Fe suffered a sudden engine failure at around 129,000 miles. The Hyundai dealer verbally told me the failure was caused by a faulty PCV valve, which is a known issue in Hyundai engines and can lead to severe oil loss, crankcase pressure problems, and ultimately engine failure. However, the printed diagnostic paperwork they provided listed a different reason for the failure, and the descriptions do not match what I was told verbally. This inconsistency makes me believe the cause is related to a known Hyundai engine defect that the manufacturer is not acknowledging. I contacted Hyundai Motor America directly, provided documentation, and requested warranty or goodwill repair assistance. They denied the claim even though the failure was due to a defective engine component and not misuse. This engine failure created a dangerous situation and appears to be consistent with Hyundai’s history of valve, oil system, and internal component defects. Given the mismatch between the verbal explanation and the written diagnosis, I am concerned the dealer and manufacturer are avoiding responsibility for a known defect. I am requesting that NHTSA investigate Hyundai for potential PCV-valve-related engine failures and inconsistent denial practices.
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.
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.
We had the oil changed like always and shortly after I was checking the oil and it was not even on the dipstick so I added some and checked for leaks anywhere did not see any than we had problems with it barely accelerating so took it to dealership the performed the anti knock sensor upgrade for free and when I asked about the oil consumption they said that I needed to do a engine clean and all kinds of stuff came to like $400 so I had them do it because I can not have my wife stranded somewhere after all that they changed the oil again that was another $80 they said to bring it back at 1000 miles for them to check brought it back at 700 miles already used 1.5 qts they said engine is junk but cannot get anything done about because it had at the time 120000 miles
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.
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.

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.
My car has a GDI motor and it is the most diabolical engine. I get an oil change REGULARY according to my cars need. Between oil changes, i have to constantly add oil. About every week i have to add about 2 quarts of oil. I have confirmed with my mechanic that i have NO leaks, no faulty gaskets or injectors. This car has caused me SO many problems. I should not have to constantly add oil to my car weekly just to get to my next oil change. There needs to be some sort of recall or extended warranty. My mechanic has stated that SEVERAL of his customers have had faulty GDI motors. My car has 118,000 miles on it and very well taken care of.
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
Engine shuttering and burning oil rapidly.
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.

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.
Check engine light came on to check the oil and I had recently had an oil change and all of a sudden within a week or two I needed to fill my oil back up and it's gone through two quarts of oil since my oil change this has been going on for 2 years I did not know there was some place like this where I could follow a complaint. I constantly put oil in my car because my car is constantly low on oil and there is no evidence of the oil leaking onto the ground whatsoever. I don't know where the oil is going to but it's not leaking on the ground and there's just been a constant issue for the past 2-3 years

Engine is burning too much oil.Tested for leaks.none. Had combustion cleaning,valve cover gasket replaced and oil changed as per Advantage Hyundai instructions.still burning oil too fast.Hyundai is hiding behind the fact that my vehicle is out of warranty because its close to 100,00 miles.This is obviously a defect in the engine and they should stand by their work and replace it with no cost to me.There are all kinds of class action suits against them because of this issue.
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
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.

Excessive oil consumption/ burning oil; oil light came on 1,500 miles after oil change.
I am unsure what component of the engine caused the issue. There was chance of engine failure while driving. While idle the engine was stuttering and the RPN dial was fluctuating. Engine persisted to stutter and jerk at random intervals when accelerating. The engine light came on flashing ~1 hour after the first sign of the issue. Immediately after the engine light came on the vehicle was moved off of the road and a tow truck was contacted to transport the vehicle to a Hyundai dealership. The vehicle was inspected at a manufacturer's dealership and the problem was resolved with a technician stating that the vehicle needed a "system update". There is also an ongoing issue with the vehicle excessively consuming oil.

I have had this car since Sept 2023, it had about 85,000 miles when I got it. Before I had even owned it for a year and before it had 100,000 miles it was burning oil at an alarming rate! I took it to my dealership which did a consumption test and told me to bring it to Hyundai. Hyundai did their own oil consumption test which results proved my car was burning 3 quarts of oil in under 1,000 miles. Hyundai refused to do anything about it as well as the dealership I bought the car from (they say it is a Hyundai problem) I have spoken to corporate who refuse to fix it because I bought it out of warranty, which I was unaware of at the time I bought it. I am a single mother who has to work full time to support my family, my car has died numerous times and I am buying oil about once a week, I have had to call out of work due to it dying and it has died with my children in the car as well. I am afraid to drive it because I know it will die and I will be stranded but unfortunately I have no other options. It is a complete safety hazard and I can not trade or refinance because even tho I havent had it 2 years, I owe more than it is worth in value.
Excessive engine oil consumption. The vehicle oil consumption is beyond my control, currently I am afraid to embark on vacation driving to friends or on vacation in other states. Low engine oil can result in engine overheating and fire, thus endangering life, family and property. I am currently adding oil every 14 days to ensure the engine is at a safe operating level for my own safety. I am requesting a one time manufacture's assistance to remedy this defective.

Bought my vehicle as second owner and 1 1/2 years into financing I discovered the piston rings are failing which is causing to much oil consumption. It’s burning oil to fast - in three weeks my car has burned through three quarts of oil. I do my regular oil changes as recommended and already change the gasket. If I have not checked my oil I would never had a clue. I am currently doing my oil changes because the dealer shops were not nor even knew of the burning oil issue. How does one car burn that much oil in three weeks. My extended warranty has exited and now my engine is failing. My vehicle was not included in the class action settlement. I am a teacher with children and don’t have the money to buy a new car let alone fix the engine. The vehicle has rough idling at times and doesn’t have the power to go sometimes. It’s failing quicker than I could imagine.
Car stopped running 4 months ago and had it towed to the shop and they did a Knock sensor update and sent us back with it. 4 months later check engine light comes on and take it in and they recommend a new engine and this car has a class action and they’re saying we don’t qualify. They’re saying it’s the piston rings. The car burns oil like crazy. Over 5 quarts in 2,500 miles consistently and the oil light never comes on. I have 2 kids that ride in this car for it to just die or for the engine to start fire is a risk I am not willing to take.

This model engine is a common complaint easily found by quick internet searches. They have recalled SOME models, but not all. This car uses EXTREME amounts of oil. It is not normal. I have not had a car in my 38 years of driving that used anything even close. I do not have any leaks. This car requires 1 quart of oil every 500-700 miles. This is horrible for maintenance. It is very dangerous to an unsuspecting buyer. I found out about this when my engine light came on and to my surprise the oil was about empty after an oil change when I first purchased the car. This was only about 6 weeks in to having the vehicle! This is also horrible for the environment, expensive, and messy. Hyundai should be held accountable. The oil consumption is due to an engine defect that is not directly related to their current Lifetime limited warranty for connected bearing rods.
While driving my vehicle, the check engine light came on, and the engine entered limp mode, severely reducing power and acceleration. This presented a significant safety risk while traveling on the highway, especially during lane changes and merges. The issue was later diagnosed by a certified Hyundai dealer as Diagnostic Trouble Code (DTC) P1326, which relates to the knock sensor detecting potential engine bearing wear. The dealer confirmed this issue and performed related inspection work under Hyundai’s Service Campaign T3G. No prior warning signs appeared before the incident. Hyundai has issued a known campaign for this issue, but no recall appeared under my VIN at the time. I incurred rental and rideshare costs due to the vehicle being held at the dealer for several days. This condition severely impacts the drivability and safety of the vehicle.

I went to get my oil changed, and I've noticed that not even 2week after the oil change the truck is 2 or 2 1\2 quarts low on oil. So, I was wondering if you have any other problems with this truck and the oil. The Santa Fe isn't linking any fluids under it.
I was driving to work when I heard a loud knocking noise in my engine shortly after beginning my trip. My vehicle then lost all acceleration power as I was making a left turn at a light. Then, the check engine and oil pressure warning lights activated simultaneously. Had the driver behind me not been maintaining a safe following distance, I certainly would have been rear-ended. After having the vehicle towed to a mechanic approved by my insurance company, I was told that the issue was possible engine failure. There were no warning lights or symptoms before this issue arose, and I still had 400 miles before I was due for another oil change.
