1 Power Train problem of the 2017 Hyundai Santa Fe

Failure Date: 01/05/2026

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.

2 Power Train problem of the 2025 Hyundai Santa Fe

Failure Date: 12/22/2025

Started car, reading paperwork and suddenly my car went into neutral bycitself and rolled backwards in a parking lot. Thank goodness no one was walking behind my car. This is the 2nd time it has happened. Additionally, twice previously, my car screen blacked off. 1 other time while sitting at a traffic light, the car shut off. I have been patient but now I'm afraid ti drive this car with only 2,650 miles on it.

3 Power Train problem of the 2017 Hyundai Santa Fe

Failure Date: 12/19/2025

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.

4 Power Train problem of the 2017 Hyundai Santa Fe

Failure Date: 12/18/2025

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

5 Power Train problem of the 2023 Hyundai Santa Fe

Failure Date: 12/09/2025

The vehicle cannot pick up speed, and it is displaying the dtc- p1c2d03. This is similar to the issues that led to "safety recall 236 to repair a condition involving the 8-speed dual-clutch transmission (dct) system" in earlier model years (till 2022) for certain Hyundai and kia vehicles. Nhtsa should issue a recall for 2023 model years also as Hyundai has not addressed this issue to the fullest extent in 2023 model years.

6 Power Train problem of the 2020 Hyundai Santa Fe

Failure Date: 11/30/2025

I had been driving about 1. 5 hours when I exited the interstate and the car engine shut off at a traffic light. When I shifted the car into park and tried to restart the car, smoke filled the cabin. Unbeknownst to me, an oil leak occurred while driving. No warning lights or other indicators that anything was awry. I had the vehicle towed to the nearest Hyundai dealer. Though the SUV is under warranty, they say the oil leak was caused by improper oil plug installation at the last oil change. The oil leak caused the motor to seize and the resulting damage is in excess of $10,000. Hyundai says the warranty won't cover this as it is a service issue. Jiffy lube says their technician did nothing incorrect and they won't take responsibility for the repairs.

9 Power Train problem of the 2016 Hyundai Santa Fe

Failure Date: 11/19/2025

The engine seized up on the highway with no warning signs or alerts and lost all power to the vehicle putting family at risk on the highway speed. Mechanic confirmed engine seized and metal debris after draining oil. Oil changes are done on timely basis within 5000 miles. Most recent where synthetic oil used and was just at 5000 mark. There was no oil warning at all and regular oil change was scheduled for next day prior to event. Car purchased in 2017 used and this happened before shortly after purchase and engine replaced by Hyundai at that time.

10 Power Train problem of the 2025 Hyundai Santa Fe

Failure Date: 11/17/2025

After a maintenance service was performed at 16500 miles, we began to notice a high pitched whistling sound when pressing gas pedal doing highway driving above 75mph. The car was brought back to the dealer who couldn’t duplicate the complaint. We drove cross country, sound consistent until it began to make the sound at lower and lower speeds. We arrived at our destination and I took the car to the dealer we bought the car from. Their tech claimed it was normal coil whine. Since it was progressing I had the manager test drive the vehicle who agreed it was not normal. After a week we switched service advisors who immediately determined it was a failing transmission that needed replacement now waiting for parts to arrive. I am requesting a buyback per California lemon law.

11 Power Train problem of the 2021 Hyundai Santa Fe

Failure Date: 10/27/2025

My transmission failed, even after the #236 recall in 2022. My car was recalled for recall #236 in 2022. My car was updated and "fixed" and now in 2025 is showing the p1c2d03 code and requiring a new transmission. The same recall, without the fix. The car is in great health and never had issues until I was going 60 miles per hour on a busy highway and it reduced to 26 miles per hour during busy traffic. Causing me to almost get rear-ended multiple times and people swerving off the highway to miss me. My car was not going, even with the gas pedal down. I had no warnings, it happened out of nowhere.

12 Power Train problem of the 2017 Hyundai Santa Fe

Failure Date: 10/25/2025

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.

19 Power Train problem of the 2014 Hyundai Santa Fe

Failure Date: 09/07/2025

Owner: [xxx] VIN: [xxx] vehicle: 2014 Hyundai Santa Fe sport my daughter purchased this vehicle in April 2025 from a licensed Chrysler dealership. On [xxx], the engine suddenly seized while driving, without warning, and would not restart. This VIN was part of recall 17v-226 (Hyundai campaign 162). Dealer records show the recall was closed with inspection only (“engine inspection, oil, dipstick”), not an engine replacement. The failure matches the defect description of the recall (bearing wear from restricted oil flow). Hyundai is refusing to repair it, claiming sludge and “maintenance neglect,” despite my daughter only owning it for 5 months and having an oil change at Hyundai in may 2025. This engine failure proves the prior “inspection” remedy was ineffective. Hyundai is also denying coverage under the lifetime warranty extension (txxi), which explicitly applies to subsequent owners for bearing failures. This is a serious safety issue. My daughter lost power in traffic, and the vehicle is still unrepaired. This complaint is being submitted on behalf of the registered owner, [xxx] , by her mother [xxx] , who is the primary contact. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

21 Power Train problem of the 2025 Hyundai Santa Fe

Failure Date: 09/01/2025

We have experienced sluggish/poor acceleration response, scary hesitation at take off regardless of how hard you depress the gas pedal and when driving and are at a speed approx. 45-55 mph and press the gas pedal as much 75% and there is no acceleration. I have had the vehicle at an authorized Hyundai dealer repair shop 3 times and have filed a formal complaint with Hyundai. Hyundai states that this problem ridden transmission is operating as designed but not admitting that the design is badly flawed, to the point where Hyundai have discontinued this transmission in the 2026 version of this vehicle. This is not a complaint based on personal preference or likes, yet it is totally based on the fact that this is drivetrain is very unreliable and unsafe.

22 Power Train problem of the 2019 Hyundai Santa Fe

Failure Date: 08/29/2025

I was driving home Friday August 29th 2025 around 10:30 am on I-70 w when I began to have trouble accelerating my vehicle. There were vehicles trailing closely behind me so I increased pressure on the gas pedal. I would feel my car forcibly trying to compensate and the rpms on the vehicle increased significantly. The check engine light then illuminated and the car stedily beagan to decelerate although rpms were increasing and the force on the gas pedal was at its maximum. I could no longer get past 30 mph. The cars behind me had to quickly change lanes behind me to avoid rear end collision and I finally pulled over to the shoulder of the highway but it was a very narrow shoulder so my safety and the safety of those driving around were compromised because they could have easily resulted in a high speed rear-end collision that could have been fatal and the location of my car on the shoulder was not safe and I could have been side-swipped waiting for a friend to come get me and for me to move my car off hat narrow shoulder. I was frantic and very emotionally distressed by this incident because all the maintenance on the car was up to date and there was no check engine light on in the car prior to this incident. The unexpected and decelleration and inability to compensate on the highway was very unsafe. I have taken my car to the delearship and they have yet to address my engine issues or the safety concerns. The rep actually laughed while I was recounting the events. I also called hagerstown police department to have a police officer come out to the breakdown site because I did not feel safe but my frined arrived before the police.

23 Power Train problem of the 2014 Hyundai Santa Fe

25 Power Train problem of the 2024 Hyundai Santa Fe

Failure Date: 08/16/2025

Vehicle information: 2024 Hyundai Santa Fe hybird sel VIN: [xxx] purchased date: [xxx] (less than one year) mileage at incident: 12,753 incident date: [xxx] dealer: kengarff downtown Hyundai summary of problem: I am filing this complaint because of a serious safety concern caused by clear dealership negligence and potential engine failure. During a routine service, the dealership failed to add engine oil, but recorded in the service invoice that it was added. I unknowingly drove the vehicle 3–5 miles without oil, and multiple dtc error codes (p052400, p001100, p001400) appeared. The oil warning light, which should have alerted me, did not activate. Although a later borescope inspection stated there was “no immediate damage,” since then, the vehicle has shown: significant loss of power and acceleration abnormally high rpms, even when the car is stopped louder engine noises rpm is increasing suddenly while driving downhill without acceleration this vehicle is less than one year old and costs over $40,000. I should not be forced to drive a new car that may have hidden or delayed engine damage. Safety concern: I have a [xxx], and I cannot risk sudden engine failure, stalling, or fire while driving. This is not only a reliability issue, but a serious safety hazard for my family and others on the road. Attempts to resolve: reported to Hyundai corporate, case opened. The dealership admitted the mistake but denied responsibility after the inspection. Hyundai corporate stated “no action until further inspection,” despite clear evidence of negligence. I continue to experience performance and safety issues. Requested action: I urge NHTSA to investigate this incident and hold Hyundai accountable for both the dealership’s negligence and the potential safety defects (oil light failure, possible hidden engine damage). Consumers should not be left to drive unsafe vehicles, especially when children’s safety is at stake. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

26 Power Train problem of the 2025 Hyundai Santa Fe

Failure Date: 08/01/2025

Bought this brand new Santa Fe in July 2025 and on day 5 after purchasing this vehicle, car stopped accelerating while driving on highway, which is a serious safety concern. Took the vehicle back to the dealership and turned out the issue is with failed catalytic converter and they had to replace it. Since then, the acceleration has not been that great and had continuous issues with random engine noises etc.

27 Power Train problem of the 2025 Hyundai Santa Fe

Failure Date: 07/12/2025

2025 Hyundai Santa Fe VIN: [xxx]   I am facing several issues that require immediate attention. Below are the unresolved concerns: transmission problems 1. When driving downhill with the cruise control on, the transmission produces significant vibrations and makes a lot of noise. This is unacceptable and needs to be checked and fixed, as I am very concerned about my safety.   2. When accelerating from speeds above 45 miles per hour, the rpms exceed 5,000, but the car does not increase in speed. The transmission fails to shift properly. This has happened three times, and it is very dangerous.   3. During hot weather, the car has stalled multiple times when I accelerate. This has put me in dangerous situations when the car stalls in traffic.   gas mileage 4. I have observed a significant reduction in fuel efficiency during high-temperature conditions. Specifically, the gas mileage decreases by approximately 20% to 30% when driving home in the afternoon heat compared to my morning commute, even though I follow the same route.     message sent to Hyundai. Com on 7/14/2025 with supporting documents.   on July 12, 2025, I arrived at my scheduled service appointment at earnhardt Hyundai regarding my 2025 Santa Fe. To ensure a thorough evaluation, I provided the service technician with a detailed list outlining the specific issues I have been experiencing with the vehicle (attached for your review). It is deeply concerning that earnhardt Hyundai did not document or formally acknowledge all the complaints I submitted to the service department. (attached invoice) this lack of attention is particularly troubling in relation to the persistent issues with the dual-clutch transmission (dct) ? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

28 Power Train problem of the 2024 Hyundai Santa Fe

Failure Date: 07/08/2025

I was driving and the car started to loose power and then the engine light came on and the car would not go. Everything happened at one time. The wrecker took the car to the dealer and the dealer confirmed the transmission went out. It is very dangerous for a new car to have the transmission fail while driving. This is a new car. The transmission failed and it is available for inspection at the dealer. The car is currently at the dealer and I am waiting to find out how long it will take to get a new power train.

29 Power Train problem of the 2017 Hyundai Santa Fe

Failure Date: 06/29/2025

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.

30 Power Train problem of the 2018 Hyundai Santa Fe

Failure Date: 06/28/2025

I am writing to formally request your review and potential intervention regarding a serious and potentially widespread mechanical issue involving Hyundai vehicles, along with the manufacturer’s refusal to honor their well-advertised 100,000-mile powertrain warranty for subsequent (non-original) owners. I am the current owner of a 2018 Hyundai Santa Fe (VIN: [xxx] ) that is experiencing a continuous variable valve timing (cvvt) system failure, which has led to a critical engine malfunction. The estimated cost of repairs exceeds $7,000, an unexpected and significant financial burden. Despite the vehicle being well within the 100,000-mile threshold, Hyundai has denied warranty coverage solely on the grounds that I am not the original owner. This policy effectively strips coverage from second-hand buyers and, in my view, is misleading given Hyundai’s extensive advertising of the 10-year/100,000-mile powertrain warranty. It creates a false sense of long-term reliability and warranty protection. This is not an isolated case. Numerous complaints have surfaced from Hyundai owners experiencing similar catastrophic engine and powertrain failures—including cvvt malfunctions, rod bearing issues, and engine seizure—raising serious questions about: the safety and reliability of Hyundai's engine systems; the fairness and transparency of Hyundai’s warranty terms and advertising; potentially systemic manufacturing or design flaws impacting thousands of vehicles on u. S. Roads. I respectfully urge the ntsb to review whether such defects present broader safety implications and to assess whether Hyundai’s current warranty practices reflect responsible corporate and consumer protection standards. Please let me know if additional information is required, including repair estimates, maintenance records, or correspondence with Hyundai representatives. I appreciate your time and attention to this matter that is affecting many vehicle owners beyond my individual case. Information redacted pursuant to the freedom of information act (fo.

31 Power Train problem of the 2017 Hyundai Santa Fe

Failure Date: 06/16/2025

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.

32 Power Train problem of the 2016 Hyundai Santa Fe

33 Power Train problem of the 2023 Hyundai Santa Fe

Failure Date: 06/13/2025

There was a recall on the 21-22 Santa Fe for a issue with the transmission oil pump failure. I have a 23 which is not part of the recall but this is exactly what happened to me and now the transmission has failed completely with 68,000 miles.

34 Power Train problem of the 2022 Hyundai Santa Fe

Failure Date: 06/08/2025

Description of problem: the transmission will disengage while driving, allowing the car to 'coast' as if in neutral. The problem sometimes occurs at red lights, where the vehicle remains stationary for a brief period and then corrects itself as if nothing happened. I noticed the "d" character flashing on the dashboard when the issue occurred, indicating a problem. The engine will rev, but the car will not move. The vehicle spent about two weeks at the dealership (Hyundai of new port richie, FL), but they were unable to find an issue after conducting over 80 miles of test driving. The last incident occurred on June 8, 2025, only days after I had removed the vehicle from the repair shop due to this problem. When pulling into my son's driveway, the car's engine revved to about three thousand rpm, and the vehicle rolled backward, out of his driveway, and into crossing traffic. Luckily, the pickup truck on the street was able to stop before hitting my vehicle, which was now sitting in his lane of traffic. I looked down at the dashboard, and the car was still in "d" but would not move forward. After a few seconds, the transmission re-engaged and moved forward again as if nothing had happened. I did nothing and the car recovered by itself! I returned the vehicle to the dealership for further investigation on June 9, 2025, and am driving a rental. Summary: this car is unpredictable and unsafe in this condition. Someone could drive this car for days without experiencing an issue, but it does happen when you least expect it! I use this vehicle for local travel only, about twenty-mile trips.
