Power Train Problems of Hyundai Santa Fe - part 1

On April 2, 2026, the engine in my 2017 Hyundai Santa Fe failed catastrophically while my wife was driving. The vehicle lost power suddenly and completely. There was no warning and no prior symptoms. She was able to pull over safely in a residential area. The vehicle was towed to an authorized Hyundai dealer, where the service representative suspects connecting rod bearing failure—the same failure mode described in NHTSA recalls 17v226 and 17v578 affecting other 2017 Santa Fe vehicles with the theta ii 2. 4l engine. The engine is available for inspection upon request. My VIN does not appear in the recall population, yet the failure is identical to the documented defect. This suggests the recall scope was insufficient. One week prior, we drove this vehicle on a 500+ mile family road trip with our child. The failure that occurred could have happened at highway speed. We are lucky to be alive. No warning indicators appeared before the failure. The vehicle has been regularly maintained. The problem has been preliminarily confirmed by the dealer as suspected bearing failure, pending teardown.

I purchase the 2017 Santa Fe sport in October of 2023 with just short of 80k miles. It was in great condition and had no issues. I have maintained it according to Hyundai specification and regular on schedule oil changes with recommended 5w-20 full synthetic. At approximately 100k miles, I experienced an oil pressure light on the dash, when checked, the engine was approximately 2 quarts low. From this point on, the engine started consuming oil at an increasing rate all while I maintained regular maintenance. First, 1 quart a month, or about 1200 to 1500 miles, then to 1 quart every 2 weeks or 800 miles. I maintained weekly checks on the oil level and on the evening of 3/24/2026, I had added a quart, bringing the level to the midway point between the high and low dipstick markings. On the afternoon of 3/24/26 while driving on the highway in heavy, but at speed limit, traffic on the highway, I experienced a loss of power and a check engine light. I was able to exit the highway but the car started to run very rough and unable to idle. Luckily, there was no traffic approaching when I turned off the exit and made a left into parking lot to shut off the vehicle. I will be having it towed to a dealership in the next few days for their analysis.

Enterprise car sales sold me this vehicle when it had 3 open recalls on it. The vehicle itself was a problem from the beginning. When I took it in for it's first oil change the mechanic told me it had no oil in it. He said they sold me a car that is notorious for consuming oil and or seizing or blowing up. I had the engine replaced on this car already and I just took it in for it's first oil change and it was already consuming oil. I want a new car but enterprise is telling me this is my problem.

My 2011 Hyundai Santa Fe (approx. 153,000 miles) developed a new stalling and engine-dying-at-idle condition immediately following a knock sensor replacement performed by a Hyundai dealership. Prior to this repair, the vehicle ran normally with no stalling or idle issues. The vehicle was originally brought in for diagnosis related to code p1326, which is covered under Hyundai service campaign t6g (engine rod bearing / knock sensor campaign). The dealership replaced the knock sensor but subsequently claimed my vehicle's p1326 condition did not qualify under campaign t6g. Immediately after the knock sensor replacement, the vehicle began stalling and completely shutting off at idle — a condition that did not exist before the dealer's service. I returned the vehicle to the dealership to address this new issue. The vehicle has now been at the dealership for over three (3) weeks with no diagnosis update, no repair timeline, and no communication from the service department. I am filing this complaint for two reasons: 1. Safety concern: an engine that stalls and dies at idle presents a serious risk of loss of vehicle control, particularly in traffic or at intersections. 2. Service campaign t6g: I believe the underlying condition and the dealer-caused stalling issue are both connected to the knock sensor system covered by this campaign. I request that NHTSA review whether this vehicle qualifies under campaign t6g and whether dealer-caused damage following campaign-related service should be addressed under the campaign or a related recall. The dealership's failure to communicate for 3+ weeks and their claim that my vehicle is not covered under campaign t6g warrants regulatory review.

1. Component/system: 2022 Hyundai Santa Fe 8-speed dual-clutch transmission (dct), specifically the transmission oil pump or hydraulic pressure system. Inspection availability: the vehicle is currently at mcgrath city Hyundai in chicago and can be made available for inspection upon request. 2. The transmission exhibited slipping gears, delayed gear engagement, loud mechanical noise, and a transmission warning light. These conditions create the risk of sudden loss of drive power, unexpected stalling, or inability to control the vehicle, which could cause accidents, collisions, or injury to the driver, passengers, or others on the road. 3. A technician at mcgrath city Hyundai initially informed us that the transmission oil pump had failed, which aligns with the symptoms. Later, another dealership representative claimed there was no issue, and the fluid was simply low. No written diagnostic confirmation or independent verification has been provided to date. 4. Hyundai corporate has been contacted and opened a case, but they refused to provide documentation or details of any inspection or repair, and did not assign a supervisor to provide clarification. No police, insurance, or third-party inspections have been performed. 5. Symptoms first appeared on March 9, 2026, including: transmission warning light; delayed gear engagement; slipping gears; loud mechanical noise from the transmission.

1. The transmission warning symptoms first appeared on March 9, including a transmission warning light, delayed gear engagement, slipping gears, and loud mechanical noise. 2. 5-liter turbo engine use an 8-speed dual-clutch transmission (dct). It has been in mcgrath city Hyundai since March 10 for inspecton. 2. We were not harmed, but were very concerned about the safety of the car. 3. We only tried and waiting for this dealer for a ddiagnosis, but they verbally gave 2 conflicting diagnoses today. No written diagnosis report, no repair report. 4. This morning (9am), a staff informed us by phone that the vehicle has a failed transmission oil pump and that the dealership was waiting for approval for the replacement part. However, during a later call (1pm) today, another staff member stated that there is no issue for the transmission oil pump, and that the transmission fluid was simply lower than normal, with no leaks. We were told to pick up the vehicle today. We refused and waiting for them to email us a diagnosis report and a repair report. 5. The transmission warning symptoms first appeared on March 9, including a transmission warning light, delayed gear engagement, slipping gears, and loud mechanical noise. This conflicting information is extremely concerning, especially given the transmission symptoms described above. Hyundai issued safety recall #236 specifically for 2021–2022 Santa Fe vehicles due to the high-pressure electric oil pump in the 8-speed dual-clutch transmission (dct) potentially malfunctioning, causing a complete loss of drive power. And there is an active class action about it too.

2024 Hyundai Santa Fe purchased new in may 2024. On three occasions since December 2025, while driving, the dashboard went completely black as if the vehicle shut off. The Hyundai startup logo then reappeared while the vehicle was still moving, and the vehicle lost acceleration. The most recent event occurred at highway speed, approximately 65-70 mph, requiring us to coast to the shoulder. No warning lights appeared before the event. A video of the most recent incident is available. Dealer inspected vehicle but could not duplicate the problem and reported no error codes.

On March 4, 2026, at approximately 7:30 am est, while driving my 2023 Hyundai Santa Fe limited on [xxx] , the vehicle experienced a sudden loss of propulsion while traveling at approximately 70 mph (posted speed limit). The vehicle would not accelerate or maintain speed and would not move forward when placed in drive, indicating a failure within the powertrain/transmission system. The vehicle is currently located at a Hyundai dealership and is available for inspection upon request. This incident created a significant safety risk, as I was traveling at highway speed in active traffic when the vehicle unexpectedly lost the ability to move under its own power. This placed me at risk of being rear-ended and made it difficult to safely maneuver out of traffic. The vehicle was inspected by a Hyundai dealership. Diagnostic trouble code p284001 (shift fork “d” position) was identified, and I was informed the failure is transmission-related. The condition was reproduced by placing the vehicle in drive, at which point the vehicle would not move. The vehicle has been inspected by the dealership. The manufacturer has been notified but has not physically inspected the vehicle. No police or insurance inspection was involved. There were no warning lights, messages, or prior symptoms before the failure. The issue occurred suddenly without any indication of a problem. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was about to turn into a 2 lane road and a warning came on my dash, "shifter system malfunction service immediately " my vehicle was in drive I was unable to move my vehicle, unable to shift into any other gear. It was sudden with no warning or loss of power prior to the warning and loss of movement.

After turning off the radio with the push button control the instrument cluster and navigation display panel went completely dead black. After pushing multiple buttons several times the panel came back to life. This has not yet been reported to the dealer. On 12/12/2025 this same vehicle also experienced faulty engine / power train components which required replacement @1199 miles. Throttle body assembly and torque converter assembly which caused loss of power when accelerating onto a high speed parkway attempting to reach @55mph along with excessive vibration when brakes were off. Took dealer 22 days to fix the problem.

Vehicle experienced sudden loss of power while driving. Transmission warning and abs warning lights appeared at the same time. The vehicle would not shift properly and began skipping and dropping gears. Smoke was visibly coming from the center underside of the vehicle near the transmission area. There was a strong burning oil or rubber smell inside and outside the vehicle. This created a serious safety risk due to loss of acceleration and potential fire hazard from smoke and burning odor. The issue has been intermittent since early ownership, including jerky shifting and hard engagement. The dealer documented dual clutch transmission communication faults and abs faults but returned the vehicle the same day stating it was a loose ground. The problem has continued after repair. Vehicle is available for inspection. The defect involves the powertrain and related electrical systems.

After making right turn after being stopped at traffic light, when I attempted to accelerate the vehicle would not shift from low gear to higher gear(s). This caused very high engine rpms for the time it took to pull the vehicle off to the side of the road and stop and turn of the vehicle . I looked at dash board for any indicator lights but didn’t see any. Restarted the vehicle accelerated back on to the road and the vehicle did change gears ok. Again looking for any dashboard indicator to be on but didn’t see any. The date of this incident was [xxx]. Made appointment on 2/10/26 for service to diagnose why this incident happened on 2/17/26 and to provide any necessary repairs at columbia Hyundai, cincinnati, ohio. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

-shift lever in transmutation stopped working so car would go into auto shut off and then would not drive once I took my foot off the break. Would not switch gears or drive. Had to shut car off then turn back on to get it to switch gears. -safety was put at risk majorly. Car did that in 5 lanes of traffic with me and kids in car and couldn’t drive. We almost got hit. -dealership said no issues found until I took it in a second time for the same issue then they said it was the translation shift leaver. -briggs kia inspected it -no warnings at all -this happened multiple times. Put the most current date.

Car stuttered and would not rev past 2k rpm. Blinking check engine light appeared code was for known connecting rod failure for all theta engines for our 2018 sante fe. Hyundai is trying to get out of covering the cost of repair or replacement even though this is a very well known issue and is covered under warranty.

I tried to drive my 2025 Hyundai Santa Fe hybrid; the vehicle displayed a gear selection error message stating something like "gear already selected". The vehicle would not shift properly and would not power off or restart. I attempted multiple shutdown and restart attempts using the start/stop button with no success. The vehicle remained in this condition for about 30 minutes and would not allow normal operation or shutdown. Due to safety concerns, Hyundai roadside assistance was contacted and a tow truck was dispatched. Before the tow arrived, the vehicle spontaneously allowed shutdown without any intervention. This was a safety related failure involving the shift-by-wire system and vehicle power-down logic. The issue occurred without warning and left the vehicle inoperable. The vehicle had app 7150 miles at the time of the incident.

While driving the vehicle at approximately at 55 mph on a the 826, the engine suffered a sudden and catastrophic mechanical failure without warning. The vehicle lost all motive power in active traffic, creating an immediate safety hazard and nearly resulting in a rear-end collision. Upon inspection, it was determined that the engine assembly, which is a replacement unit provided by Hyundai under the theta ii settlement, with less than 12,000 miles, suffered an internal breach. This breach allowed coolant to contaminate the lubrication system sort of a milky oil, which led to a connecting rod bearing seizure. Despite this being a repeat failure of a safety-recall component and the vehicle being covered under the theta ii settlement lifetime warranty, Hyundai motor America has denied the repair claim. I am reporting this as a safety defect because the sudden engine stall resulted in a loss of power-assisted steering and braking while the vehicle was in motion.

I was driving on the road and all of the sudden my car went limp and would only move 45 miles per hour. I took it to the dealer which I have lifetime powertran on my car. It has been there for over a month at the dealer. They asked me to provide all oil changes,services, and registrations. I did that and then fidelity asked them to tear down the engine again to see if I had carbon build up. Then after the dealer did that they ask the dealer to tear the motor down even further to see if the exhaust valve was bad and if it was bad they would not replace my motor. My car consumed so much oil that I was changing my oil so often. I have been renting a car just to get back and forth to work. In my contract it says that the exhaust valve is covered under my lifetime powertran. I feel like Hyundai and fidelity are giving me the run around. I took very good care of my car and I have shown that. Hyundai has had alot of problem with there motors with the oil consumption and motors just going limp. I feel I will never buy a Hyundai again. I am losing money everyday because of the dealer and fidelity. I need the motor replaced and it was no abuse on my part I took care of my car. I want fidelity to tell me how I abuse the exhaust valve. I did my oil changes and took care of my car. I am still paying on my Hyundai and can't afford another car. I have alot of medical bills that I pay. Any help would be great. Sincerely [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle has now had several incidences of completing losing all acceleration power while driving at both high and low speeds, resulting in need to turn on hazards and abruptly pull to side of road. Pushing on gas pedal does nothing and vehicle will even roll backwards if I pull over on a hill and take my foot off the brake. I have to put vehicle in park and turn off. Sometimes I have to restart the vehicle a few times before it will drive forward after putting it back into drive. The vehicle does not lose electrical power and will sometimes display the master warning light on dashboard and other times have no dashboard indicator of a problem. This is an extremely dangerous situation and my VIN is not listed under safety recall 22v-746 despite exhibiting the same behavior. I have contacted my local Hyundai dealership service in past and they recommended a transmission flush which did nothing to alleviate the issue. It is now happening frequently so we are reaching out to the local Hyundai dealer service center again.

Component/system failure: the electronic throttle control system malfunctioned. The vehicle is reporting powertrain diagnostic trouble codes p2118 and p2101 through the Hyundai manufacturer mobile application (bluelink), indicating an electronic throttle actuator / throttle control motor issue. The vehicle is available for inspection upon request. Safety risk: this malfunction poses a safety risk because it can cause sudden loss of throttle response, reduced engine power (limp mode), or stalling while driving. Loss of throttle control increases the risk of a crash, especially in traffic or at intersections. Reproduction / confirmation: the issue is ongoing. The check engine light remains illuminated and the fault codes continue to be displayed in the Hyundai mobile application. The problem has not yet been diagnosed by a dealership due to lack of immediate service availability. Inspections performed: the vehicle has not yet been inspected by a Hyundai dealership or the manufacturer due to delayed service appointments. No inspections have been performed by police or insurance representatives. Warning indicators / symptoms: the check engine light illuminated and remains on. Diagnostic trouble codes p2118 and p2101 are displayed in the Hyundai mobile application. The warning light first appeared in late January 2026. Current vehicle condition: the vehicle is considered unsafe to drive due to the active electronic throttle control fault and risk of sudden loss of power.

The vehicle intermittently fails to reverse properly, hesitates, jerks, and at times locks despite no obstruction present. This occurs during normal use and creates a serious safety concern, particularly when backing out of parking spaces or into traffic. In addition, the vehicle exhibits ongoing electrical issues, including intermittent warning lights, rearview camera distortion or failure, inconsistent system operation, intermittent inability to unlock using the key fob or door handle, and the vehicle fan or air system continuing to run for extended periods after the vehicle has been turned off. These issues occur without consistent warning and have not been resolved despite multiple service visits. The vehicle is also subject to an active safety recall (NHTSA recall 26v218000, manufacturer recall 298) involving the front seatbelt anchor. The recall remains unrepaired, with no remedy currently available. I have personally experienced the seatbelt becoming stuck and not releasing properly, which presents an additional safety risk. The vehicle also experienced a battery failure. I was initially informed that the battery could not be replaced without cost; however, it was later replaced. Despite repeated concerns, the hybrid battery system was not tested or evaluated, and this remains an unresolved issue affecting vehicle reliability and safety. Additionally, the vehicle has experienced tire tread separation and peeling requiring replacement. This is not consistent with normal wear and may indicate alignment, suspension, or other underlying vehicle-related defects. The vehicle has been inspected by the dealership multiple times; however, the issues were not reproduced and no corrective repairs were performed. These problems are intermittent and occur during regular day-to-day operation. Collectively, these unresolved issues present an ongoing safety risk to the driver and others.

My 2025 Hyundai Santa Fe hybrid has recurring powertrain communication failures starting at only 67 miles and continuing at 5,300 and 6,200 miles. Diagnostic trouble codes include u010100 (lost communication with engine control module) and multiple u100xxx codes related to transmission and can bus communication failures. These indicate loss of communication between critical control modules. The issue has happened multiple times and remains unresolved. I am concerned this could cause drivability problems, warning lights, or sudden loss of power. This appears to be a system-level defect in the vehicle’s communication network.

The contact owns a 2021 Hyundai Santa Fe. The contact stated that while driving approximately 20 mph, the vehicle experienced hard shifting while attempting to change gears, and the vehicle hesitated, and the check engine warning light illuminated. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired; however, dtc: p1c2d03 was retrieved. The vehicle was then taken to a dealer, where the same diagnostic trouble code was confirmed. The dealer diagnosed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 99,700.

We took it in to be looked at after it had a O2 sensor go bad I changed the sensor and checked fluids I noticed the oil was a touch low and it had metal on the dipstick. I took in to dealership for repair / replacement and Hyundai denied the claim. Even after I have video proof from the dealer technician saying there is metal and bearing material in the oil. I took it to another dealership and they found metal in the oil control valve and still denied it. We got the car back because we were not provided a loaner or a rental. I called back in with concern that the car had a weird burning smell and the car would die. Then it started sounding weird as well. Then called again Saturday because I checked oil and it had fuel smell in the oil. Now today it left my family stranded on the highway. I have th 100,000 mile ten year warranty and the car is only at 83480 miles now when this all started it was at 82000. I have expressed my concern of safety before it finally left my family vernable to be injured in the lane that it died in this afternoon. Many denied claims and now very dangerous situation that was preventable and could have cause fire or death. I brought to manufactures attention early to prevent a accident happening. I was denied all the way through the process .

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.

On 6/7/2023 with the original owner, the vehicle displayed code p1c2d03, according to carfax history the transmission was replaced 7/12/2023. I purchased the vehicle in may, 2025. In December, 2025, while driving to work I experienced intermittent loss of ability to accelerate, followed by the vehicle again displaying code p1c2d03 in the bluelink app. The dealership performed a software update and told me to come get my car. On Monday, February 16, 2026, I started the vehicle and the dash displayed "transmission error. Check transmission fluid immediately!", I again had it towed to the dealership where it has remained for the past three weeks. Now I have been called again to pick up the vehicle as the dealership cannot duplicate the error. At this time I am unsure if the service center actually checked the transmission fluid as the warning indicated should be done.

Car had an unintended acceleration. I had been stopped prior to entering my garage. I had started to slowly accelerate when the car accelerated hard. It took a lot of effort to stop the car.

Complaint: safety defect - engine failure risk (stalling/fire) my 2019 Hyundai Santa Fe has the defective theta ii 2. 0l turbo engine (g4kh), subject of class action in Hyundai and kia engine litigation and multiple tsbs. The engine has a known manufacturing defect causing premature connecting rod bearing failure, leading to catastrophic engine seizure. Safety consequence: this defect presents a clear, unreasonable safety risk: sudden stalling: engine can seize without warning while driving, causing loss of propulsion and power steering/brakes, leading to a crash. Engine fire: failed engines can leak oil onto hot components, causing fires. Manufacturer's inadequate remedy: Hyundai's "knock sensor detection system" software update (campaign 966) only attempts to detect failure moments before it happens. It does not fix the underlying mechanical defect. The engine remains a ticking time bomb. Personal experience: my vehicle has suffered multiple related failures (turbocharger, fuel injectors) costing over $5,700, confirming the powertrain's deterioration. I fear driving it, especially with my teenage daughter. The defect is well-known, yet Hyundai's settlements fail to protect subsequent owners like myself, leaving unsafe vehicles on the road. Request: I urge NHTSA to investigate the ongoing safety risk these engines pose to all owners, compel Hyundai to issue a true safety recall for a permanent repair (e. G. , engine long-block replacement), and mandate clear disclosure of this defect to all used car buyers.

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.

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.

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.

While driving my 2024 Hyundai Santa Fe, the vehicle experienced a complete dashboard and system blackout, as if the vehicle shut off and rebooted. This has occurred on two separate occasions. On one occasion, while stopped at a traffic light, the dashboard went completely black and restarted. After the system rebooted, the vehicle would not accelerate or move when the accelerator was pressed. I had to turn the vehicle off, restart it, and wait before it would drive again. The suspected malfunction involves the vehicle’s electrical/infotainment and related vehicle control systems. The vehicle is available for inspection upon request. My safety and the safety of others were put at risk because the vehicle lost critical dashboard information and temporarily lost the ability to accelerate while in traffic, creating the risk of being struck by other vehicles. The vehicle was inspected by an authorized Hyundai dealership (world Hyundai of matteson). On December 23, 2025, I was informed by the dealer that a system/infotainment “glitch” had been identified and that a replacement part would be ordered. However, the part was never replaced. The dealer later stated that because the issue could not be duplicated during test drives (approximately 85 miles driven), the repair was not authorized. The dealer acknowledged the issue could not be reproduced on demand. The manufacturer (Hyundai) has not yet physically inspected the vehicle beyond dealership involvement. No police or insurance inspections occurred, as there was no crash. There were no warning lamps or messages prior to the failure. The failure occurred suddenly with a complete dashboard blackout and system restart. The first occurrence happened prior to December 23, 2025; the second occurred afterward. The issue is intermittent and unresolved. I am concerned that the defect must reoccur while driving in order to be repaired, posing an ongoing safety risk.

Since December my car has been burning oil at a fast rate. My husband has already had to add an additional 4 quarts since my last service 3000 miles ago. I have read and heard from others with a Santa Fe that they are having to replace their engines because of this. They are under warranty. Unfortunately I am not. I’ve already dealt with a white paint issue with Hyundai. I called couple weeks ago and was told someone would email me and they have not. I’m not sure where to turn now.

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.

Code p1c2d03 is popping up on my 2021 Hyundai Santa Fe after the dealership "fixed" the recall in 2023. My car is going into limp mode, failing while driving, and unsafe. Dealership and corporate won't help me. The transmission was never replaced with the recall and they are claiming they aren't relatable and can't do anything unless a recall is reopened.
