general problems of the 2017 Hyundai Santa Fe - part 2

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.

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.

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

Approximately six weeks after purchase, my daughter drove the vehicle to a school event and back without issue—no warning lights, noises, or drivability concerns. Shortly thereafter, when attempting to leave for another event, the Santa Fe failed to start. I attempted a jump-start, only to discover that the engine had seized suddenly and without prior warning. It is available for inspection if needed. This sudden and unexpected malfunction could have happened while driving down the road and who knows what might have happened to include my daughter being seriously injured. The vehicle was towed to our local Hyundai dealer. Where the service team confirmed catastrophic engine failure. The engine has only been inspected by the local dealer. There were no warning lights, noises, or drivability issues prior to the engine failure. This engine failure happened on Aug. 16, 2025 references for review NHTSA recall report 17v-578 – notes crankshaft pin and bearing wear issues leading to potential stall. Nhtsa federal register (dp24-001) – acknowledges Hyundai’s 15-year/150,000-mile warranty extension via TSB 24-em-003h.

Hyundai TSB 22-em-006h-2 (txxm) – illustrates Hyundai’s approach to extending coverage for engine failures.

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.

The engine seized back in August 2025. The engine stopped working while I was driving on a main street and almost caused an accident. Unfortunately I put other drivers at risk when this happened. The engine issue was confirmed and inspected by the victorville Hyundai dealership in California. There was not any warning lamps prior to this.

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

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

I am reporting a sudden engine failure involving my 2017 Hyundai Santa Fe sport 2. 0t. At just 68,000 miles, the vehicle experienced catastrophic loss of power due to zero compression in cylinder 1. The vehicle is equipped with the theta ii turbocharged engine, which has been the subject of previous investigations and safety recalls due to premature failure risks, including stalling and fire hazards. This failure occurred on [xxx], while I was driving on the highway. There was no warning. It put all drivers near me at risk as I had no power, was traveling in the left lane and had to navigate through 3 lanes of traffic to reach the breakdown lane. I request that this case be investigated further as a potential safety risk and recurrence of known issues with this engine type. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2017 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power after the engine made an abnormal sound. The check engine warning light was illuminated. The vehicle was taken to a local independent mechanic to be diagnosed, but the cause of the failure could not be determined. The vehicle was not repaired, and the failure reoccurred. The vehicle was towed to a local dealer, where dtc: p1326 was retrieved, and the vehicle was diagnosed with knock sensor signal range error, metal shavings intrusion into the engine, and other unknown failures. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 67,000.

My Hyundai Santa Fe has a major oil leak from the oil pressure light. I took the car to a non-Hyundai shop for repair and was told that the problem should be covered under recall campaign 168. Reference number: 17-01-071, date of issue: December 01, 2017. A quick check of internet complaints indicates this is a common problem with this type vehicle. My oil pressure light is on at idle after the car is warmed up. Reno Hyundai dealer informs me that it is not covered by recall. I believe that this problem should be covered based on the volume of complaints from other owners. Can your organization help me in getting some kind of an cost adjustment for getting this repaired. Thank you.

My vehicle is a 2017 Hyundai Santa Fe sport awd with a gdi theta ii 2. 4l 4 cylinder engine. We purchased it in Feb. 2024 with 120,310 miles. Since then we have only put approximately 8,000 miles on it in 17 months. On Aug. 1st 2025 while driving up a hill out in the country the engine suddenly quit. Of course the steering and the brakes failed to operate. However I was able to coast to the next road and barely able to turn the wheel but made the corner and coasted to a stop. Without a nearby corner I would have been stuck on a state highway with many semi-trucks traveling on it. Could have been much more dangerous for my wife and I especially since we had to have the car put on a flatbed to be hauled home. The person who came to haul it checked the battery which was fine. You could hear the starter engage and try to turn the engine but it would not turn one bit. Once home we had a mechanic with many years experience have a look and listen to it. He could not get the engine to move even when trying to turn it by grabbing the engine belts and pullies. By all appearances the engine is seized. No warning lights were one and the oil was checked that very morning before leaving home. The vehicle was using about 1 qt of oil every 200 miles or so. Always used a high quality oil of proper weight/viscosity. Had no visible oil leaks on ground where it was parked every night. Hesitate to spend hauling fees to take it to the dealer 40 miles away if they are not going to do anything but offer to replace it for many thousands of dollars. For a couple living on social security this can absolutely turn things upside down as we only own one car (which we still owe on).

Engine excessively burns oil. Failed oil consumption test. Hyundai denied warranty claim, citing maintenance neglect, despite oil change maintenance records and documentation.

Driving on main road , car came to complete stop while waiting on traffic light and vehicle loss power , and wouldn’t accelerate. No , dash lights nor sounds were on prior to it loosing power nor stalling .

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? blown head gasket how was your safety or the safety of others put at risk? engine overheated and coolant boiled in 110 degree weather. Has the problem been reproduced or confirmed by a dealer or independent service center? yes by Hyundai. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes by Hyundai. Hyundai states that engine needs to be replaced because the head gasket isn’t repairable on the 3. 3l engine. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no, engine overheated once and diagnosis was blown head gasket.

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.

Motor replacement. I had taken my car several times into Hyundai for oil consumption issue. I replaced the recommended parts through Hyundai and ended up having to come right back after being stuck on the side of the interstate due to lack of compression two cylinder two I was told I needed to replace the motor. This has been a very expensive process and I haven’t had the car but 10 months.

My car had a thrown connecting rod-the problem described under tsb22-em-006h-2 (txxm/6g) which extends engine warranty to 150k miles/15 years for this exact issue my VIN is listed my mileage is 113k and ksds was completed (or I am exempt) please submit prior approval under the extended warranty for engine replacement. Hyundai is refusing to repair my car.

Engine oil excessive consumption. We bought (sept 2024) this 2017 vehicle used at a hyundia dealership, beautiful, loaded orange SUV, for my senior college student. We have to add quart after quart after quart of oil in-between oil changes. She hardly drives the car as she walks to class and works 1/2 mile from her apt. We are scared for her to take even a 2hr road trip due to this issue. She is devasted and scared to drive it much and we are furious that we are stuck with this issue.

Excessive oil consumption from metal shaving left in engine during production. Causes accelerated engine wear and failure. Rod bearing failure. Piston ring failure, high chance of fire in engine compartment.

Engine failed at 114,000 miles. Burned 2 holes through 3rd cylinder. Was almost struck crossing intersection making left hand turn when vehicle stalled and would not accelerate to get back into normal driving lane.

I purchased my 2017 Hyundai Santa Fe sport secondhand from carmax and have maintained it regularly with timely oil changes and tune?ups. Despite this, the vehicle is burning oil at an extreme rate—approximately 1 quart every 378 miles. My local Hyundai dealership confirmed this through three consecutive 1,000?mile oil consumption tests, all showing excessive oil loss far beyond normal operating limits. This level of consumption appears to indicate an internal engine defect, not normal wear. Hyundai corporate denied my case solely because I am the second owner, even though the vehicle is well under 100,000 miles and the defect has been verified by their own technicians. The denial did not address the confirmed test results or the safety implications. I am deeply concerned that the engine could seize while driving due to rapid oil loss, creating a serious risk of sudden loss of power, stalling, or inability to accelerate in traffic. This is a significant safety hazard for me, my passengers, and other drivers. The vehicle has been inspected by the Hyundai dealership, and I am fully willing to make it available for further inspection. A low?oil warning lamp appeared far earlier than expected after a routine oil change, which prompted the initial investigation and ultimately revealed the defect. Based on my research, this appears to be a known issue affecting Hyundai gdi engines from this era. I am filing this report because the excessive oil consumption represents a latent engine defect with clear safety implications, and Hyundai has declined to address it despite documented evidence.

Excessive oil consumption leading to p420 codes every 2000 miles. Vehicle is consuming a half a quart of oil every 100 miles. Could cause engine to seize while driving.

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 approximately 40 mph, the "low oil" warning illuminated. The contact drove back to the residence and checked the oil level on the dipstick and became aware that there was no oil in the engine. The contact added 4 quarts of engine oil and drove the vehicle to the dealer. The dealer initiated an oil consumption test. The vehicle was taken to the same dealer three more times before the dealer determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The contact stated that the engine had been replaced two years prior due to excessive oil consumption. The failure mileage was approximately 160,000.

Was driving on the pennsylvania turnpike, near breezewood, PA (approximately 130 miles from home), when a loud clunking and metal on metal sound was heard, the causing power loss, slowing of vehicle and necessitated immediate pulling over to the side of the road. The was a catastrophic internal engine failure which caused the spark plugs to blow out. There were no warnings. The car was just inspected and had an oil change earlier in the month. The vehicle suffered sudden power loss and violent metal-on-metal destruction while transporting my child on the pennsylvania turnpike (130 miles from home). Certified diagnostics from kennett square quick lane auto confirm: "multiple spark plugs forcibly ejected due to severe internal engine damage – full replacement required". Quick lane said they would not be able to replace the engine. So the vehicle was towed to reliable car connection (west chester, PA). I had tried to make an appointment at piazza Hyundai, but the did not have appointments until mid August. Result: stranded overnight requiring hotel and towing/tolls at personal expense (receipts available). This traumatic event directly stems from Hyundai’s acknowledged theta ii defects. Hyundai’s documented failures: recall compliance: recall 996 (piazza Hyundai, 4/12/24) recall 953 (1/31/19) recall 163 (7/18/17) maintenance: all services performed per Hyundai schedules (records available). Unresolved defects: this failure matches: recall 20vh4 (lifetime warranty extension) recall 20vh5 TSB 20-01-033h current status: vehicle at reliable car connection (west chester, PA) after piazza Hyundai’s unacceptable 6-week delay. Inoperable & unsafe – cannot transport children.

The contact owns a 2017 Hyundai Santa Fe. The contact stated while driving on the highway at 65 mph, the contact heard a loud bang coming from the engine. The contact stated that immediately afterwards the vehicle started losing motive power with smoke coming from the front and the rear of the vehicle. There was no warning light illuminated. The contact pulled over and had the vehicle towed to a local dealer to be diagnosed. The contact was informed that additional diagnostic tests were needed to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage 152,530.

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.

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.

My vehicle we bought from carvana has been jerking/misfiring and now with no warning on freeway it wouldn't give power stalling. There was no warning nothing no lights came up. I drive my kids in this vehicle I've taken it to multiple mechanics they say they couldn't find why it's jerking and it must be a manufacturer issue. I looked online and yes lots of issues with the make and model recall about the crankshaft sensor cause these issues!!!.

This vehicle has experienced numerous serious failures, including two engine replacements, a transmission replacement, and persistent safety system malfunctions. The downhill brake control (dbc) system remains stuck in the "on" position, and the traction control warning light stays illuminated. These issues directly compromise vehicle safety and stability, particularly on hilly or wet roads. Despite extensive service at arapahoe Hyundai in centennial, CO, these problems continue to return. The vehicle has been in the shop multiple times and was most recently in service for nearly 30 days. My wife was stranded at the dealership today due to the same unresolved safety system failure. Dealer communication has been poor, and repairs are often incomplete, requiring immediate return visits. The repeated failure of safety-critical systems, combined with the inability to resolve the issues long-term, presents a significant safety concern for both my family and others on the road. I am requesting NHTSA to investigate whether this is part of a broader defect pattern affecting 2017 Hyundai Santa Fe models and if a recall is warranted.

The car has been experiencing significant problems with oil consumption. During a routine oil change on 2/27/25 I was told my oil was significantly low and I had it refilled. When I checked the following weekend [xxx] it was significantly low again after only 500 miles. I took it to take 5 in lebanon, tennessee, weekly for 3-4 weeks, near where I was working at the time, who topped off the oil again with 2 to 5 quarts weekly. On April 14, 2025, I brought the car to hallmark Hyundai. They started an oil consumption test and a 20-point check when the mileage was 69,752. After 500 miles was driven, the oil tank was almost empty. Another check revealed the oil was leaking in 4 different places, that they (hallmark Hyundai) reportedly fixed, including the valve cover gasket. On [xxx] while driving back to new jersey from nashville, I checked the oil after roughly 1000 miles of driving since the repair, and the dip stick was dry. (the service light did not go on. ) upon returning to new jersey approximately 5/13/25, I took the car to circle Hyundai in shrewsbury, new jersey, was told the valve cover gasket was still leaking, and replaced it again; I was charged a second time for this service. At another 500 miles I checked the oil, and it was again very low. Miguel at circle Hyundai told me I needed to wait 500 more miles or when the service light comes on; I informed him the service light had stopped working (this was first noticed in tennessee). On 6/2/25 I emailed miguel again at 539 more miles and the dip stick registered oil halfway below the low line again. I was instructed to drop the car off and they would submit the claim to Hyundai; Hyundai reportedly responded that they were no longer responsible for a repair because the warranty had run out and I wasn't the original owner. I was told to continue to drive until an engine malfunction for my extended warranty with assurance to cover repairs; I am concerned about the safety of the engine seizing. Information redacted pursuant to the freedom of inf.

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