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.
2017 Hyundai Santa Fe engine complaints
Page 4 of 24: complaints 71 to 100 of 673, newest first, as owners wrote them.
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.
“My 2017 Hyundai Santa Fe Sport 2.4 has been experiencing severe oil consumption issues for a long time. I previously completed a combustion chamber cleaning service as recommended, but the problem continued. On November 10, the Hyundai dealership confirmed the engine oil was low and topped it off. On December 10, the oil was completely empty again with no warning lights. The dealer has documented the issue and recommended an engine replacement, but Hyundai is refusing to approve the repair . The vehicle continues to lose oil rapidly, creating a serious safety risk of engine failure or stalling while driving. This appears to be a known safety-related engine defect affecting this model.”
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.
# **the federal safety agency Complaint Answers** ### **1. What component or system failed or malfunctioned, and is it available for inspection upon request?** The **engine** failed due to **sudden and extreme oil consumption** that resulted in the engine being completely dry of oil despite regular maintenance. This caused internal damage including **CVVT (Continuous Variable Valve Timing) system failure**, bearing damage, and a complete engine seizure. Yes, the failed engine is fully available for inspection upon request. The vehicle is currently located at Dick Smith Hyundai in Greenville, South Carolina, where the dealership diagnosed the failure and recommended a full engine long block replacement. ### **2. How was your safety or the safety of others put at risk?** The engine failure occurred **suddenly and without warning**, causing the vehicle to lose power while operating. The loss of engine function created the risk of: * sudden deceleration in traffic, * inability to accelerate or maneuver, * potential rear-end collision, * complete engine stall in unsafe conditions. The vehicle had **no oil warning light** prior to the failure, meaning I had no indication that the engine was at risk until the failure occurred. ### **3. Has the problem been reproduced or confirmed by a dealer or independent service center?** Yes. The engine failure was confirmed by: • **Schwab’s Automotive** in Fayetteville, NC – determined the engine suffered catastrophic internal damage and was not repairable. • **Dick Smith Hyundai** dealership – confirmed **high oil consumption and CVVT damage**, and recommended a full **engine long block replacement** (estimate: $8,160.60). The problem has been fully verified by both an independent mechanic and an authorized Hyundai dealership. ## **4.Yes.The vehicle was formally inspected by Hyundai Motor America through the dealership’s diagnostic report. Hyundai reviewed the case (Case #XXX) after receiving the dealership findings.The engine remains intact avai. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF IN
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.
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 suffered a crankshaft/bearing failure identical to the federal safety agency 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.
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
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.
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 the federal safety agency 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 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.
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.
I bought this car a 2017 in December 2023. The first time I got the oil change they told me there’s no oil on a stick and then couple months later again no oil on the stick so I took it to my personal mechanic. He said there is an oil consumption problem so you advise me to take it where I bought it from. I had to go up there for 1000 mile test and then a 500 mile which I was low. Seems like every two weeks I had to put oil in it so where I brought the vehicle from told me to go to Hyundai. Hyundai only did one oil consumption test. I have a records of oil changes from Valvoline, my personal mechanic, Tradition Ford and one from Hyundai. Tradition Ford, where I got the car from with disappointment because I had a lot of proof that I was burning oil. There was no leak. There was no smoke at all. Besides it being under 10 years old, I was under 100,000 mile warranty and I had an extended warranty. tradition Ford where I bought it from took that one back however I lost $7000 from the down payment. I bought new tires for it, new battery, remote starter, spark, plugs, and rain guards. I still have all my papers from that vehicle 2017 Hyundai Santa Fe sport 2.4 engine liter.
Engine excessively burns oil. Failed oil consumption test. Hyundai denied warranty claim, citing maintenance neglect, despite oil change maintenance records and documentation.
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.
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.
Per our mechanic: Timing components blew a hole in the valve covers because they were so loose. It is burning massive amounts of oil. Could start with timing components and new valve covers, but it will most likely need a new engine because valve train damage is very likely.
We have continued to experience, over at least the past 6 months, and at least once a week and under all driving conditions, a stalling and unable-to-restart problem with this vehicle. Usually after waiting a short period of time it will restart, but in one case we had to have it towed to the dealer. The engine typically turns over just fine, so it's not a battery or starter issue. In a couple of instances it won't turn over. We've taken it to two different Hyundai dealerships and they haven't been able to diagnose the problem because they aren't able to replicate the problem when the vehicle is in their possession. The situation is becoming increasingly dangerous. The last time it stalled, my wife was in the middle of a very busy intersection. The problem doesn't produce any codes that the dealership can see; when it stalls and we attempt to restart, most of the dash lights that regularly come on when you start it are displayed. I am aware of a recall (uploaded PDF) for the make, model and year of my vehicle but apparently it only applies to certain VIN numbers. When I enter my VIN its shows no open recalls. However, the problem described in the recall is identical to the problem we are having.
At about 105,000 miles the oil ran dry after 800 miles of fresh oil change, it just started using oil no leaks no smoke from the tailpipe.now I have to add a qt every 200 miles and on start up the top of the engine rattles for a few seconds. A loud rattle. I have taken it to the dealership several times they did a engine cleaning and several other things but it didn’t help just cost about 800 bucks. Prior to that we changed oil every 5000 miles. Not always the same place, the dealership, Tess corners auto did quite a few of them. Some by jiffy lube. We don’t take the car on long trips anymore, afraid it will not make it. Karen n Chris
In May 2025, the vehicle (2017 Hyundai Santa Fe) developed severe sluggishness. The vehicle was taken to the dealer and I was told the engine would need to replaced due to a recall. Four months later (week of Sept 14 {exact date not known}), the engine was replaced and the vehicle made available for pickup. I drove it home (8.1 miles) and all seemed normal. It sat in the driveway for approx. one week. On Sept 22, 2025, I drove to the store (8.4 miles round-trip). On the way to the store, the engine light came on. I immediately called the dealership and reported the problem. The car was taken in that night (a trip of 8.1 miles) and left at the dealership. On Sept 23, 2025, I was informed that the intake manifold needed to be replaced (this had caused the engine light to come on) at my cost of approx $1000. The car remains at the dealership (unused by me). Online research revealed that if debris had been found in the manifold, it was to be replaced along with the engine (Hyundai TSB #22-EM-010H DATE JULY 2022). The following has been cut-and-pasted from the web: The issue of the intake manifold not being replaced or cleaned after an engine failure is a direct result of the core defect. When the old engine failed, it likely shed metallic debris and shrapnel. That debris could have traveled into other components, including the intake manifold. If the manifold is not cleaned or replaced, the new engine draws that old metallic debris back in, causing it to fail again almost immediately. the federal safety agency indirectly mandated that the repair must be COMPLETE AND EFFECTIVE. When a dealership refuses a critical part of that repair (like cleaning the manifold), they are effectively carrying out an incomplete remedy to a safety recall, which is a violation of the manufacturer's federal obligation under the Consent Order. It is my contention that residual debris in the intake manifold caused the warning light and will quite possibly damage the new engine.
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 the federal safety agency Recall Report 17V‑578 – notes crankshaft pin and bearing wear issues leading to potential stall. the federal safety agency Federal Register (DP24-001) – acknowledges Hyundai’s 15-year/150,000-mile warranty extension via TSB 24-EM-003H.

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.
This car has oil consumption issues due to a manufacturer defect, design of the engine 2.4L. This has been on going for the last three years and is getting worse. Now is affecting the catalytic converter because of it burning so much oil. The Hyundai dealership will do nothing for me. Now they want $4,500 for a new catalytic converter. I can’t afford a new car and this should be an expense of Hyundai. In my research I have found there are thousands of cars on the road with this issue. They knew about this years ago and just kept making the cars and selling them . They should be helping me and all they are doing is denying that this has a problem. What recourse do I have. Why hasn’t there been a recall?
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.
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.
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!!!
Subject: Urgent Safety & Warranty Concern – 2017 Hyundai Santa Fe Sport (TSB #21-01-002H) Dear Hyundai Customer Care and the federal safety agency, I am reporting a serious safety and warranty concern regarding my 2017 Hyundai Santa Fe Sport (VIN: [XXX] , 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. the federal safety agency 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, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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).
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.
