Power Train Problems of Hyundai Santa Fe - part 1

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.

Maintenance has been maintained on this SUV. SUV has about 20,000 miles. While at a complete stop at stop light, the SUV jerked a few times and when attempting to drive the accelerator pedal the SUV would not respond. I then put in park then back in drive slow acceleration, was able to pull over. After turning SUV off and waiting a few minutes , turned SUV back on engine light is on. Home is 10min.

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).

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.

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.

In relation to this incident, approximately 3,00 miles after an oil change, the engine oil drain plug fell out and caused all oil to leak and cause engine damage. Engine oil change was at approximately 125,000 miles. Drain plug fell out at approximately 128,000 miles. No warning lights or symptoms were present prior to vehicle shutting off and dying while driving. Vehicle was then towed to shop who previously did oil change. Shop confirmed drain plug was missing and oil level was empty. I am the manager of this shop submitting this on behalf of the customer with this vehicle. We are aware of the ongoing concerns in relation to case dp22-003 and would like to submit this information as further evidence for this case.

The contact owns a 2022 Hyundai Santa Fe. The contact stated that after starting the vehicle, the warning message "shifter malfunction - service immediately" was displayed, and the gear shifter failed to shift from park(p), rendering the vehicle undriveable. The cause of the failure was not yet determined. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not yet notified of the failure. The failure mileage was 61,000.

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).

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.

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).

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.

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.

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.

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.

I need to replace engine block assembly and the following codes p1326 c1207 c1210 c1211 c1206 c1208.

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.

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.

Bien,mi auto tuvo varios problemas al mismo tiempo: 1-falla en todo el sistema eléctrico,aire acondicionado,control DE tráfico ambas partes, power steering,abs,pérdida DE potencia en el motor,problemas con el receptor DE la llave remoto,tiene un problema eléctrico sin precedente todo ocurrió DE la nada,todo ocurrió un mismo día cuando íbamos camino a una excursión mi familia y yo estuvimos en un gran riesgo,todos los componentes han sido inspeccionados y no he podido aún arreglarlos porque se necesita el consecionario DE este automóvil para descubrirle las grandes fallas que presenta,aún tiene 3 señales en el tablero, check engine, power string, abs, todo prendió después del problema.

I bought this vehicle at enterprise car sales back in March 2nd 2019 and it's been having issues for a while now recall after recall I bought this vehicle at 7745 indiana avenue riverside California 92504 I actually bought this vehicle without realizing that this car had a recall prior to buying it off the lot therefore in California law this company should have not sold the vehicle with a recall as Hyundai has warned me about this as he advised they cannot sell a vehicle with a recall on it. When I had to google search my recall as I have not received a letter enterprise car sales gained the letter for the recall prior to my buy and did not mention anything as this recall was sent out on the letter way prior to buying ever since buying this vehicle I have had numerous recalls as to now there is a gdi issue with the engines as I have made many complaints through the financing company santander consumer USA, Hyundai, enterprise car sales, and it seems like no one has listened to me on the lemon I have gained as I'm sure it sounds just like a complaining customer. I pay a very high interest rate and very high monthly payments 523 a month is expensive let alone expensive to pay for a vehicle that I constantly have to put in maintenance and now my engine is gone my VIN number somehow is not on regards to the recall but yet my VIN number has been on every recall Hyundai has ever given out when it comes to my vehicle as the gdi 3. 3 l should be really considered on regards to a recall as well as the 2. 4. I'm not very happy as I would like to have a voice on to what is fair I am sick of this vehicle having issues after issues as I do take care of my vehicles with good maintenance routine all I can ask for is to have someone here my voice and to take action either from enterprise car sales to Hyundai which I believe enterprise car sales is more reliable at this point than Hyundai since Hyundai let me be aware of the California law they cannot sell a vehicle with recall.

Driving vehicle at highway speed, engine rpms dropped to less than 1500, could not maintain any speed, cel illuminated. As soon as vehicle was pull to side of road, it would no longer run. It would start, idle roughly then stall out. Vehicle was towed to mountain Hyundai in denver. High pressure fuel pump failed, fuel pump in one cylinder failed, fuel was dumped into oil fouling all spark plugs. This is the second high pressure fuel pump failure on this vehicle.

This truck has repeatedly gone in for service over 6 times for multiple issues. The worst issue which they cannot fix is the vehicle going into limp mode while driving . Loosing all acceleration then racing on its own . This is a very dangerous problem when on the highway. Hyundai service keeps telling me that the diagnostic is not showing a problem. This can be caused due to many things including transmission electrical or computer problems. I have reported to the office of consumer affairs and they claim Hyundai dealership in myrtle beach has not responded to them. Meanwhile I am driving in a very scary situation not knowing when this will occur. This happens at random times with no warning. This has happened at least 10 times in the last few months.

All of the bolts that hold the cvvt assembly backed out and one came completely out. It punctured a hole in my valve cover. Oil sprayed all underneath my hood and leaked out on the road. The car went into limp mode while I was driving, and had I not already pulled off the street, this would have caused a multiple vehicle accident. I had the vehicle towed to the manufacturer dealer and they confirmed the issue. The only warning lamp that came on was the check engine, and that didn't happen until I had already pulled over. Thus all happened within a matter of 10 minutes of driving.

I am reporting an urgent request immediate action regarding a serious unresolved, recurring public safety issue with my vehicle. It is potentially the fault of alexandria Hyundai's service department (in alexandria, va) who had just serviced my vehicle for what should have been a routine servicing (on may 7). My car had a catastrophic and complete failure on a high speed highway (the car quickly decelerated) which represented an incredibly danger situation for myself and other drivers on the road. My car was purchased in 2023 and has 15,241 miles. It has been perfectly maintained. On [xxx], I was returning to my home in virginia from maryland on an 8 lane highway with a 55mph speed limit when I had a very dangerous complete failure of my car. Simultaneously, the car started bucking back, the speed was decelerating regardless of my pressing the accelerator to keep my speed the same as traffic, and I received a flashing large red message that said "check hybrid system - stop safely. " fortunately I was in the far right lane and was able to veer it over to a narrow shoulder. It was 8pm and getting dark. After a short while, the car lost all power so I was on a narrow shoulder with no lights flashing anymore. I was in this dark car with a lot of traffic speeding my with my 2 dogs. I became incredibly stressed about how we were going to get home. I contacted aaa, a police officer and uber pet who worked together in this unsafe situation on the side of the highway to get myself and my dogs home into the uber vehicle with only the front door opening (no power). It was over 2 hours before I was home safely it was incredibly stressful situation. The car was towed to alexandria Hyundai and they dismissed the issue and fixed nothing. I contacted Hyundai customer service and asked for escalation and they have done nothing. I am restricted in my driving because of the severe safety risk but had to drive again on [xxx] and it occurred again on a highway information redacted pursuant to the freedom of information act (foia), 5 u.

This vehicle has two instances of transmission disengagement. One at highway speed and the other while driving in a residential area. In both cases the vehicle suddenly started to slow down, and the rpms went up to 4-5 thousand. I was able to stop the car and turn it off and after a few minutes restarted the car and completed the journeys without any further issues. I have contacted the dealer and will be taking the car in for a diagnosis. I did not notice any warning lamps or other symptoms before each occurance.

Transmission caused vehicle to loose speed on grade posted speed 70mph I could not get over 35 transmission stuck in 3 gear or would stay in 8th gear unable to gain speed almost got rear-ended vehicle has a 8 speed automatic transmission it will not shift properly loss of power account improper gear for speed.

A shifter malfunction error appears on dash. When trying switch into any gear it, the dashboard and front headlights flash. When I was parking, I put the car in park, the dash said park however the car kept moving and I almost collided into car in front of me. Another incident happened the same day when I could put the car in reverse from drive. I couldn’t turn the car off. Eventually I was able to turn it off but I had to put the emergency brakes on to keep car from moving. The error will appear when driving which is scary. The check engine light will appear sometimes. The car is scheduled for service on may 7th at empire Hyundai of new rochelle.

I am writing to express my concern regarding an ongoing and persistent issue with excessive engine oil consumption in my 2015 Hyundai Santa Fe, subject: severe oil consumption issue - 2015 Hyundai Santa Fe - VIN: 5xyzwdla1fg238718 the vehicle consumes an alarming amount of oil, approximately 1 quart every 300 miles. This rate of consumption is far beyond what is considered normal and strongly suggests a serious mechanical or manufacturing defect. I have already taken the vehicle to a mechanic to diagnose and attempt to resolve this problem. Based on their professional advice, the following parts were recently replaced: 1. Engine valve cover gasket 2. Turbo charger oil line 3. Spark plugs unfortunately, despite these repairs, the issue of excessive oil consumption remains unresolved. The rate of oil loss remains consistent and dangerously high. This was first informed by a service center when I took the car for a random check. Then, after traveling 1,000 miles, the engine oil level dropped again. After that, I am keeping an eye on that. This level of oil consumption poses a significant risk to the engine's long-term health and reliability, and it is a major inconvenience and expense for me as the owner. I am deeply concerned that a major engine component may be failing.

Ever since new this SUV will periodically hesitate when trying to accelerate. I have almost been rearended numerous times over the last few years do to this issue. I have had the SUV into the dealer and complained about this issue every time and they cannot seem to do anything about the issue. The have update software (or at least said they have) and done other things and it has made no difference. This issue almost caused a serious accident just this week when I was trying to merge into traffic on i5.

Vehicle is shuddering/jerking upon acceleration due to a defect in the 8 speed automatic transmission. This condition was reproduced by Hyundai of Plymouth, MA and documented on the repair order. Dealer states that a new transmission is required to fix this problem. Safety is at risk due to shuddering upon acceleration which causes hesitation in acceleration. My Hyundai Santa Fe is available for inspection. There should be a recall on this vehicle.

When shifting gears whether from parking to drive or from drive to park, the vehicle lags and makes a juttering noise. I am unable to move from the gear it is juttering in unless I turn the car off or hope that pushing the button turns it off. Whist it is juttering, it sounds as if the car is turning on and off repeatedly. This also has happened from the auto stop when trying to accelerate after stopping at a light and it get stuck and unable to move without me turning the car off and turning it back on. This is a safety issue since I was in the middle of a road, and I essentially have no control over what my car does. I have taken my car to patrick Hyundai in schaumburg, IL multiple times and they do nothing about it since they "don't see it happening whilst it is there". I have videos of it and they still do nothing.

Vehicle will not change out of ev electric mode and return to gas power causing hybrid battery drains to zero, vehicle loses acceleration, you can push the gas pedal to the floor and you have no acceleration, very unsafe when you are in traffic, no power to maneuver or avoid other vehicles quickly if needed, potential for accidents, hybrid system warning lights and alarms go on, have to try and pull over safely, battery will not recharge or takes a very long time to do so, only recourse is to shut vehicle off and restart which seems to reset vehicle, which in turn does not leave any warning lights other than codes on to show dealer, very dangerous to lose all acceleration capacity while in traffic, this has happened multiple times with the latest being today 3/23/25, vehicle is available for you to inspect, have had other powertrain codes issues as well, dealer has replaced fuel pump and erg valve but it does not resolve this hybrid issue, this battery drain issue has occurred multiple times but no resolution, help!.

When accelerating from a stop, my car will not go over 20 mph. It just revs up like it’s not changing gears . I have to pull over and park it. It runs fine afterwards. This does not happen all the time. Usually it happens once a month. It’s been to the dealership 3 times. They drive it around the block and tell us that they can’t replicate the problem. Therefore, they don’t troubleshoot anything and return the car to me. I’m truly scared to drive it. I wrecked twice at a red light intersection.
