2025 Hyundai Santa Fe Hybrid Owner Complaints

Vehicle is 2025 Hyundai Santa Fe Hybrid. Component that failed was the electrical system, specifically, the 12 V battery drained leaving the vehicle's electrical systems completely dead. Happened on two occasions: first in XXX, and second in XXX. Vehicle had to be towed in both instances. Our safety was put at risk in that my wife and I, who are both senior citizens, were essentially stranded in dark parking garages at night and left to arrange towing services under very difficult circumstances. In both instances, the electrical system was examined by Hyundai service technicians. The first time I was without the vehicle for 11 days. The second time I was without the vehicle for 22 days. Both service calls identified and confirmed that an unknown power drain was the source of the problem, and in both instances replacing the 12V battery was "the solution". The dealerships that serviced the vehicle ran all diagnostics and could not pinpoint the source of power drain; neither could assure me that it would not happen again, more or less at random. There were no warning lamps, messages or other indications of the problem prior to failure and the dealerships that serviced the vehicle (one in [XXX] and one in [XXX]) indicated that if it were to happen again, there likely would be no advance notice in that instance, either. Result: I have no confidence that the vehicle will not leave me stranded in an unsafe location/condition far from home or a vehicle service facility. Vehicle is parked in a surface lot next to our apartment in [XXX] while I shop for a new (non-Hyundai hybrid) vehicle.

I only am entering Automatic Emergency Braking because I have no other section to select. While my wife was driving our 2025 Hyundai Santa Fe Hybrid at a speed of approximately 55 mph the vehicle suddenly, without any type of warning, began slowing down to a speed of 20 mph. A message appeard on the display above the steering "20 mph limit". The vehicle decreased the speed from 55 mph to 20 mph in approximately 5 to 6 seconds. She could not accellerate above 20 mph regardless of how hard she tried. She had no control of the speed. Fortunately she was on a two lane highway with little or no traffic. She stopped the vehicle and put it into Park, waited and began travelling again. It would not go over 20 mph and the message remained on the screen. She managed to get home. When the vehicle was parked, turned off and then turned back on the message was no longer on the screen. I then drove it directly to Hyundai dealership to report the problem. I was told they could do nothing unless they were able to get the vehicle to repeat the issue. I had to leave it at the dealership. I have since read that Hyundai has a "Fail Safe" mode that causes the vehicle to do that if there is an issue with the engine, hybrid mode, transmission or emissions. This issue happens with ablolutely no warning. I just begins to stop. My major complaint is that this could occurr when I am traveling at 70 mph on a major Interstate hwy while in the left lane in high traffice and have no way of maintaining my speed long enough to get to the shoulder of the road. This could easily create a major catastrophe. Hyundai should address this issue ASAP before someone is killed because they have no control of the speed of the vehicle.

The contact owns a 2025 Hyundai Santa Fe Hybrid. The contact stated that while driving 75 MPH, the vehicle unexpectedly lost power and decelerated to 30 MPH. While in heavy traffic, the contact pulled over to the side of the road, waited for the battery to charge, and drove to the dealer at a slow speed. The dealer inspected the vehicle and associated the failure with low ethanol and heavy contaminants in the fuel. The fuel pump was replaced, and a fuel injector service was performed, but 30 days later the failure reoccurred. The high-pressure fuel pump and the high-pressure fuel pump sensor were replaced and repaired. The contact stated that several days after the repair, the check engine warning light was illuminated. The vehicle was returned to the same dealer, and the contact was informed of a catalytic converter failure caused by the contaminated fuel. The manufacturer was made aware of the failure by phone. The failure mileage was approximately 14,362.

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving approximately 65-70 MPH, the vehicle shut off. The contact pulled over to the side of the road and restarted the vehicle. During an oil change appointment, the dealer informed the contact of Hyundai TSB Number: 25-01-028H-1 (Seat Heater Unit Software Update) and associated the bulletin with the failure. The dealer completed the repair; however, the failure persisted. The contact stated that the failure identified in the TSB had caused the battery to drain. The vehicle was taken to the dealer, where the HPCU and main wiring harness were replaced twice, the battery was replaced once, and the transmission was replaced once; however, the failure persisted. The contact stated that while driving approximately 20-25 MPH and coming to a stop on an incline, the vehicle shut off. Several messages, including "HEV Low Battery - Hibernation Mode", were displayed. The contact stated that the vehicle failed to restart. The vehicle was shifted into neutral and rolled into a nearby parking lot. The vehicle was towed to the dealer, where the contact was informed that the vehicle was repaired. The manufacturer was notified of the failure by phone and email, and a case was filed. The failure mileage was 23,489.

I am filing a safety complaint regarding my 2025 Hyundai Santa Fe Hybrid, which I purchased as a Certified Pre-Owned vehicle in April 2026 with approximately 15,000 miles. The vehicle currently has approximately 27,000 miles. While driving on the [XXX], my vehicle suddenly and unexpectedly lost propulsion. The vehicle’s electrical systems remained on, but it would no longer accelerate normally. There were no warning lights, messages, or alerts before the loss of power. I was in active freeway traffic with numerous vehicles behind me. Because my vehicle could no longer maintain speed or accelerate, I was placed in an extremely dangerous situation. I feared being struck from behind by another vehicle. It was a terrifying experience. I was eventually able to pull over to the side of the freeway. I turned the vehicle off and waited briefly before restarting it. I was then able to get off the freeway and reach a gas station. Once at the gas station, multiple warning lights illuminated on the dashboard, and I observed that the hybrid battery was not charging. The vehicle ultimately became undrivable. The vehicle was towed to Centennial Hyundai in [XXX] for diagnosis. The dealership advised that diagnosis could take approximately two to three days. This is the first time the vehicle has experienced this failure. However, the sudden loss of propulsion without any prior warning created a serious risk of a rear-end collision. I am concerned that this failure could happen to other Hyundai Santa Fe Hybrid owners while driving at freeway speeds. I am requesting that NHTSA review this incident as a potential vehicle safety defect, including the sudden loss of propulsion, lack of advance warning, and apparent hybrid charging-system malfunction. At the time of this complaint, the cause of the failure has not yet been confirmed by the dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2025 Hyundai Santa Fe Hybrid has multiple ongoing problems. Several are intermittent. BRAKES: The brake pedal intermittently sticks when I first start the car. STARTING/ELECTRICAL: On two occasions the vehicle would not start and roadside assistance had to come to start it. It is also sometimes hard to start. The Digital Key on my phone intermittently fails to unlock the doors or start the car. On occasion, all audio is lost at startup, including the radio, speakers, and turn signal sound. The front left speaker intermittently cuts out or sounds distorted. The passenger front door exterior handle/unlock intermittently fails. The driver side temperature knob is stuck at 77 degrees F. POWER TRAIN: The vehicle hesitates/stutters during the first half mile of driving after starting. SEATS: The driver seat memory intermittently fails to move to the saved position when the car starts. SUSPENSION: A creaking, spring-like noise occurs when the car rocks during initial acceleration and braking, possibly from the driver side front. I have reported this to the dealer twice before. Inspection: I have reported these problems to Westlake Hyundai in Thousand Oaks, CA, on previous visits and have another service appointment scheduled. The vehicle has not been inspected by the manufacturer, police, or insurance. I am concerned about the brake pedal and no-start problems as safety issues.

Incident

Jun 1, 2026

While driving at freeway speeds in normal traffic conditions, the vehicle experienced a sudden, complete loss of motive power and rapid deceleration. The accelerator pedal became entirely unresponsive. No warning messages, check engine lights, or diagnostic indicators appeared on the dashboard during or immediately after the failure leaving me blind to the vehicle's state. This loss of propulsion on a high-speed live freeway created an immediate, extreme safety hazard, forcing an emergency maneuver across active lanes of traffic without predictable vehicle control. Component or System: Engine / Powertrain / Fuel System (High-Pressure Fuel Pump / Fuel Rail Sensor) Recurring / Prior History: This is a severe, recurring safety defect. The exact same highway power loss and deceleration event occurred last month. The vehicle was brought to an authorized Hyundai dealership where a repair was allegedly completed on 9/11/2026. However, that repair failed to address the root cause, and the dangerous failure has now repeated itself. The lack of a dashboard warning light masks a systemic component failure (strongly suspected to be the high-pressure fuel pump or associated pressure sensors failing to maintain adequate rail pressure under load

Incident

Oct 22, 2026

Beginning in early October 2026, my 2025 Hyundai Santa Fe Hybrid Calligraphy has repeatedly experienced a sudden and complete loss of propulsion while driving. During these incidents, dashboard warnings appear stating "Check Driver Assistance System" and "Check Hybrid System. Stop Safely." The vehicle indicates EV mode and completely loses the ability to accelerate or maintain speed. This is not reduced performance or hesitation. The vehicle loses all usable propulsion. The vehicle continues moving briefly while slowing, providing only a short window to reach the roadside. In moving traffic, this creates an extremely dangerous situation because there may be insufficient time or space to safely change lanes before the vehicle slows substantially. The failure occurs without advance warning. Shutting the vehicle off and restarting it temporarily restores normal operation, but the malfunction continues to recur unpredictably. On October 21, 2026, I brought the vehicle to an authorized Hyundai dealership specifically for this problem. The service department reported finding no diagnostic trouble codes and no applicable software updates. No cause was identified, and no repair was performed. The identical failure occurred again the following morning, October 22, 2026, less than 24 hours after the dealership inspection. The underlying cause remains unidentified. The dealership has not reproduced the malfunction, and the vehicle remains available for further inspection. This recurring complete loss of propulsion presents a serious collision risk to occupants and surrounding motorists, particularly in heavy traffic or at highway speeds.

Sep 28, 2026

On September 28, 2026, my 2025 Hyundai Santa Fe Hybrid (49,682 miles) experienced a second sudden loss of propulsion while driving on the highway. The vehicle would not accelerate normally, the hybrid battery gauge dropped to a very low level, and the dashboard displayed a warning instructing me to stop the vehicle and leave the engine running to recharge the battery. I pulled over and waited with the engine running until the battery recharged sufficiently to drive to the dealership. This was the SECOND occurrence of a dangerous loss-of-propulsion problem. On August 21, 2026, while driving approximately 70 mph on I-75, the engine RPM increased dramatically despite the vehicle slowing down, as though the transmission had shifted into Neutral. There were no warning lights. The vehicle slowed to a stop and required towing to Hyundai of Kennesaw. Following the first incident, the dealership identified diagnostic code P0191 and replaced the fuel-rail pressure sensor under warranty. However, the September 28 failure occurred despite that repair. During the second dealership visit, technicians again identified P0191, confirmed the previously replaced sensor was functioning properly, and reproduced the problem during a road test. Live diagnostic data showed fuel pressure dropping to low-pressure pump readings. The dealership diagnosed a failing high-pressure fuel pump and replaced it under warranty. I retrieved the vehicle October 7, 2026, after the dealership reported a successful 10–12-mile road test. I am concerned that this repeated, sudden loss of propulsion presents a serious highway safety hazard, particularly because the initial repair did not prevent recurrence. I previously filed an NHTSA complaint regarding the August 21 incident.

Sep 28, 2026

While driving on the interstate at highway speed, the power driver's seat began moving forward on its own without any switch being pressed. It didn't stop and kept moving toward the steering wheel. I am 6'3" and normally sit far back, so the seat was pushing me into the steering wheel and I could no longer sit safely or control the vehicle normally. I had to exit the highway abruptly and pull onto the shoulder to avoid a crash. This put me and other drivers around me at risk. Since the incident, the power driver's seat does not respond at all. None of the seat switches (forward/back, recline, height, tilt) produce any movement or sound. I checked the fuses and they are all intact. I have video of the switches not working. The vehicle has not yet been inspected by a dealer. It is under warranty and will be taken to a Hyundai dealer for diagnosis and repair. The vehicle and the failed seat components are available for inspection. Warning lights or messages before the failure: none Suspected cause: UNKNOWN, possibly a seat motor, seat control module or wiring fault. I have videos to share.

The vehicle has a recurring intermittent failure that can leave it completely undriveable. When starting the vehicle, the instrument cluster displays “Check Hybrid System,” “Check Emergency Stopping function,” the check-engine light, and multiple warning indicators. The vehicle remains in Park and will not shift into Drive. This has happened multiple times. Disconnecting and reconnecting the 12-volt battery temporarily restores operation, but the problem later returns. After a reset, the check-engine light may remain illuminated for approximately one day before disappearing. During the most recent occurrence, the vehicle became disabled at approximately 8:00 PM in a retail parking lot while my family, including two young children, was with me. The vehicle would not move. We had to leave the vehicle and walk in the rain to obtain tools so the 12-volt battery could be disconnected and reconnected in order to get the vehicle operating again. The problem was reported in writing to a Hyundai dealership before an August 10, 2026 service appointment, including a request to retrieve and document stored and history diagnostic trouble codes. The condition remains unresolved and continues to recur. The vehicle is available for inspection upon request. Separately, this vehicle also has an unrepaired Safety Recall 288 involving the rearview camera. The vehicle has been taken to the dealer for recall service, but the recall remains incomplete because the dealer stated the required part was unavailable.

The vehicle repeatedly loses motive power while being driven at highway speed. It slows even with the accelerator pressed to the floor, does not shift into higher gears, and drops to 40 to 50 mph. On [XXX], the vehicle lost power at highway speed while I was driving. I had to stop on the shoulder of the hwy. The vehicle could not be driven and was towed to the dealer. The dealer opened R.O. No. [XXX] on 9-3, recording mileage in of 23,595. It inspected the vehicle and confirmed the concern. It replaced the fuel rail pressure sensor (Part No. 35342-2M400) under warranty, confirmed a good idle with no codes, and performed a test drive of about three miles. The dealer reported the vehicle ready on 9-15-26; mileage out 23,596. On [XXX], within a few miles of picking up the vehicle after the first repair, the malfunction indicator lamp illuminated. We returned the vehicle to the dealer the same day; the dealer recorded the mileage in as 23,602. The MyHyundai app shows active Diagnostic Trouble Code P00BD00 (Mass or Volume Air Flow "A" Circuit Range/Performance — Air Flow Too High), powertrain system, recorded at 23,600 miles, with a listed date of [XXX]. The dealer returned the vehicle on [XXX]. On [XXX], four days after the 2nd repair, we brought the vehicle back to the dealer. We reported that it was idling high, at about 1,200 to 1,900 RPM while stopped, and that we had heard a low clicking sound since the repair. The dealer did not keep the vehicle. The next morning, [XXX], about 7 miles from home, the vehicle lost power on a bridge on [XXX]. It slowed to about 50 miles per hour and did not appear to shift. I stopped on the bridge with my [XXX] daughter in the car. VDOT responded. My husband and I switched cars. [XXX] then drove the vehicle. After about two miles it again lost power, and he had to leave the highway and use secondary roads at low speed to get to the dealer. The car is currently at the dealership.

I purchased my 2025 Hyundai Santa Fe Calligraphy Hybrid September 1, 2025. On June 24, 2026, I was driving on the interstate to work when my acceleration quickly dropped out and I wasn't able to go more than 30 MPH. This was terrifying to happen! I wasn't able to make it to an exit and had to pull off on the side of the interstate and await a tow. I took it to the dealership I purchased it from. Documentation stated that a fault code DTC P019100 (fuel rail pressure sensor) was identified. However, this sensor was not replaced. Instead, my paperwork indicates that the "air box was installed incorrectly at manufacturing and they fixed it." On August 13, 2026, I experienced a similar issue on a 45MPH secondary highway. I was able to restart it and get it to a Hyundai dealership a mile away (not the dealership I purchased from). After 5 days of no vehicle (and no loaner provided), the same code DTC P019100 presented and they replaced fuel rail pressure sensor. September 25, 2026, a critical error popped on my screen. Hyundai app says DTC P042000 (powertrain fault code). It's currently in the shop with the dealership I purchased from. I did put in a safety claim with Hyundai Customer Care and suggest all other users do the same to hold Hyundai accountable. I will attempt to update this if I can after resolution is hopefully identified. I'm very close to turning this car in and getting a more reliable vehicle. Which is unfortunate because I qualified for 0% APR financing when I purchased and I'll never get that deal again.

Incident

Sep 25, 2026

The primary component failure is within the hybrid powertrain control architecture, specifically involving the transmission control system or internal transmission clutches/modules (TCM/HEV control module). The vehicle utilizes a 6-speed automatic transmission integrated with an electric motor. During highway cruising, the transmission locks into a single gear ratio or a protective "limp mode," resulting in a total loss of normal acceleration despite high engine RPMs. The vehicle and its components are fully intact and available for inspection upon request. My safety and the safety of others were put at severe risk because the sudden, unexpected loss of acceleration occurred while traveling at highway speeds in active traffic. When the transmission locked and power cut out, the vehicle rapidly shed speed and dropped to a hazardous 20-35 mph on a high-speed roadway. This created an immediate, extreme risk of a high-speed rear-end collision from vehicles traveling behind me, forcing me to make defensive lane changes toward the shoulder without normal engine power to navigate safely. This happens without warning no notices or errors pop up when it happens. The issue is intermittent and has been presented to an authorized Hyundai dealership technician multiple times. Because the vehicle often resets its communication modules and temporary limp-mode parameters once the ignition cycle is turned completely off and back on, the dealership technicians have encountered difficulty pulling permanent historical diagnostic trouble codes (DTCs). However, the failure patterns match a widely documented, repeating issue among 2025 Santa Fe Hybrid owners regarding HEV torque calculation or loose engine wiring harness pin tension
