Hyundai Motor America (Hyundai) is recalling certain 2016-2018 Santa Fe, 2017-2018 Santa Fe Sport, 2019 Santa Fe XL, and 2014-2015 Tucson vehicles. The Anti-Lock Brake System (ABS) module could malfunction and cause an electrical short, which could result in an engine compartment fire.

Risk: An engine compartment fire while parked or driving can increase the risk of injury.

LATCHES/LOCKS/LINKAGES:HOOD:LATCH

Hyundai Motor America (Hyundai) is recalling certain 2013-2017 Santa Fe and Santa Fe Sport vehicles. In the affected vehicles, the secondary hood latch actuating cable may corrode and bind, causing the secondary hood latch to remain in the unlatched position when the hood is closed.

Risk: If the hood is not securely closed or the primary latch is inadvertently released and the secondary latch is not engaged, the hood could unexpectedly open while driving, increasing the risk of a vehicle crash.

ENGINE AND ENGINE COOLING

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.

ENGINE

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

FUEL/PROPULSION SYSTEM

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.

ENGINE

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.

ENGINE

Excessive oil consumption/ burning oil; oil light came on 1,500 miles after oil change.

ENGINE

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.

ENGINE

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.

ENGINE

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.

ENGINE

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.

ENGINE

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.

UNKNOWN OR OTHER

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.

ENGINE

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.

ENGINE

At approximately 65,000 miles the car started using excessive amounts of oil in the crankcase. I visited the local Hyundai dealer who changed my oil and began monitoring the condition. I was instsructed to come back to the dealer every 1,000 miles for an oil top off and to report the consumption. On the third visit, the engine is now using approximately 2 quarts of oil in 1,000-1,100 miles. Extremely excessive. I inquired about a warranty claim but was denied since I was the second owner. Yet, Hyundai acknowledges problems with this engine and have established broader coverage for engine problems stemming from the rod bearing which includes coverage for the second owner. The high oil consumption underscores another problem with this horrible engine, and high oil consumption should be included in a recall and repairs.

My ABS and Traction Control lights keep going off, intermittently. They have been doing it for several years.It can be for hours or for days. I took a video of it happening a couple years ago, and photos, also. More recently my speedometer has started jumping. I had the ABS recall performed when it was first implemented. When I've taken my vehicle to Hyundai (twice now specifically for this) they say they can see no codes and will do nothing. From what I have read on the ABS recall, this is what are the symptoms of it. I am under the impression that I have somehow gotten a defective part, even when they did the recall. The recall was that it could cause an engine fire. Today driving home, for a second, downhill, the oil light came on for a second-then went off. I came home and parked. My husband checked. He said there is no oil in the car. That, I imagine is part of the other engine issue this model has. But you would think the oil light would come on sooner and STAY on. He is going to get some oil and then take it to a shop when he gets off work. My main concern is getting the ABS/speedometer fixed as I believe it is from the first recall. The second issue-that is probably a Hyundai "recognized" issue. They just keep telling me nothing is wrong with the ABS/speedometer though. I have photos spanning several year, it falls in line with the recalled issue. Just replace the part already. The last date I went to Hyundai was Monday last week, so I'll put that as the incident date, as I was there for the ABS/speedometer. I had to drive an hour each way to see them twice now to be told they can't do anything. Today the oil light came on.

While driving on a highway in April 2025, my 2017 Hyundai Santa Fe Sport suddenly lost all power after approximately 10 minutes of normal driving. All dashboard warning lights illuminated, and both the accelerator and brake pedals became unresponsive. I was forced to stop the vehicle using the handbrake in the middle of a 65 mph highway, creating an extremely dangerous situation for myself and other drivers. Prior to this incident, the vehicle had displayed the P1326 knock sensor code multiple times over a 10-month period, each time accompanied by hesitation when accelerating. The knock sensor was replaced twice under used car warranty by Honda. Despite these interventions, the same code and symptoms recurred. The Hyundai dealership(Dec 2024 at Montgomery, Jan 2025 at Enterprise) repeatedly stated that there was “nothing wrong with the engine.” After the highway failure, the vehicle was inspected by a collision center and an independent mechanic. They confirmed that Cylinder 4 had no compression and diagnosed a burnt valve. Full engine replacement was recommended. Hyundai initially indicated that the engine might be covered under the extended warranty but later denied the claim, stating that the damage was due to a cylinder issue and can not check bearing failure. They also claimed it was too late to determine whether the bearing was the cause. This is not an isolated issue. Many Hyundai owners across the U.S. have reported identical symptoms—P1326 code, hesitation, cylinder compression loss, and ultimately engine failure—particularly in vehicles equipped with the Theta II engine. These failures often occur around or after 100,000 miles, despite regular maintenance. This ongoing and widespread cylinder-related engine failure presents a serious safety risk and must be addressed through manufacturer accountability, improved diagnostic standards, and proactive repair or recall efforts.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving at an undisclosed speed, the low oil warning light illuminated on the instrument panel. The contact later added 2 quarts of oil to the engine; however, not too long after adding the oil, the contact checked the dipstick, and the oil had been consumed. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was taken to the dealer to be serviced and the contact was informed that the engine oil was abnormally low. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 98,000.

ENGINE

Excessive Oil Consumption caused the PCV Sensor/Actuator (Exhaust Camshaft Timing Oil Control Valve) to fail. While the vehicle is still operable, the failure causes engine timing to change resulting unpredictable losses in power during acceleration, excessive fuel consumption, and incomplete combustion passing through the Catalytic Convertor posing a risk for future component failure. In the four months that the vehicle is operating in this condition, with its check engine light on, I have had two near collisions while attempting to merge into roundabouts and freeway entry. Fortunately, both were avoided. I no longer attempt freeway entry during rush hour. Two independent service repair shops did a computer diagnostic test and confirmed the problem with the PCV components. They suggested that the excessive oil condition be corrected first. Otherwise, any replacement components will continue to fail. Excessive oil consumption appears to be a chronic problem in the Hyundai 2.4 L engine. The engine and drivetrain is covered under a 10 year or 100,000 warranty. A year earlier the dealership performed a controlled test when the vehicle only had 60,941 miles, where the initial oil loss was 2.5 quarts per 1,000 miles. An Oil Chamber Combustion Clean, where solvents are used to remove excess carbon was performed. It temporarily reduced the oil consumption to .7 quarts per 1,000 miles. This is still requiring a replacement of about 2 Quarts of oil between routine oil changes in a 5 quart system. The dealership indicated that it passed. About 3 months later the oil consumption increased to 1.0 Quart per 1,000 miles and 8 months later the PCV components failed. If the dealership did the right thing and repaired the engine to eliminate oil consumption, everything would have been fine. I am still trying to get the dealership and Hyundai to honor their warranty. for excess oil consumption. With it the PCV components are also replaced and all is good.

ENGINE

On December 28th, 2024 I was driving my SUV on the highway at highway speeds. I bought the suv from a Manchester Acura dealer on November 9, 2024. I am the second owner. While driving, the check engine light came on. I was able to complete my drive, but the car idled very rough. After getting the car home, my father checked the oil. It did not register on the dip stick. He put in about two quarts of oil. The check engine code was P0302, which is misfire in cylinder two. He proactively changed the spark plugs since the car had 92,000 miles on it. After changing the plugs, the code did not clear and the engine continued to idle rough. He did a compression test and confirmed that cylinder two had less than 50psi compression vs the other 3 cylinders which were at 170 psi. He also removed and inspected the new plugs after running the engine and cylinder 2 plug was already dark and oily whereas the other plugs were in as new condition. I opened a case with Hyundai Care America. They instructed me to take the suv to a Hyundai dealer for diagnosis. The verbal report of that diagnosis was burnt valves on cylinder two. The dealer stated that HCA would not cover a repair or engine replacement. Hyundai forums and NHSTA complaints are numerous around high oil consumption and burnt valves on Theta II engines. Hyundai needs to be held accountable.
