What 67 owners told NHTSA about the 2025 Hyundai Santa Fe Hybrid Hev

My 2025 Hyundai Santa Fe Hybrid AWD was serviced under warranty on 4/22/2026 for a driveability concern after experiencing a loss of power while driving. The service history shows part HY35326-2M500 was replaced. On or about 5/25/2026, the same issue occurred again while driving at highway speed. The vehicle suddenly lost motive power and dropped from approximately 70 mph to approximately 30 to 40 mph, creating a serious safety risk because the vehicle could not maintain speed with surrounding highway traffic. No warning lamps, dashboard messages, or diagnostic codes appeared during the failure. The vehicle is currently at a Hyundai dealership for inspection and repair for the repeat issue and should be available for inspection upon request. The prior dealer record appears to describe the issue generally as a “driveability concern,” but the current repair diagnosis and full repair notes are still pending. It is unknown whether the dealer has reproduced or confirmed the failure during the current visit. I am reporting this as a sudden loss of motive power at highway speed involving the fuel/propulsion system, engine, and/or powertrain.

Driving home from church this morning, the vehicle experiences a sudden loss of power and the car went into “limp mode”. Even the pedal floored and the engine rpms high, the car would barely go about 25 or 30 mph. A message from the dash board told me to pull over and leave the engine running to charge the EV batteries. The batteries would charge enough for what I thought would get me home but quickly drained leaving repeat the action until I could limp the six miles home with flashers on and cars passing me to get around. No warning lights and no indication there was a problem until it happened leaving me baffled and frustrated. I was just thankful that I wasn’t going faster when it happened. If I had been going faster when this happened, it could have created a major accident. Dangerous! Since this happened on Sunday, the dealer wasn’t open. I hope to get it to the dealer tomorrow to find out what is going on and how to fix it. The car has only 14850 miles on it.

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving approximately 65 MPH, the vehicle unexpectedly decelerated to 25 MPH with a “Vehicle Will Shut Down” warning message displayed. The contact stated that the engine then began to shut down, and although the accelerator pedal was depressed, the vehicle failed to accelerate and stalled. The failure occurred on multiple occasions, requiring the vehicle to be towed each time. The vehicle was towed to the dealer; the vehicle was not diagnosed or repaired and the contact was informed that the failure could not be duplicated. The manufacturer was made aware of the failure and multiple cases were opened, The failure mileage was approximately 3,300.

The 2025 Hyundai Hybrid Santa Fe SEL has experienced two instances (Nov 2025, 11k miles & Apr 2026, 14k miles) where the combustion engine fails to provide power to the vehicle’s wheels. The engine continues to run, but only enough to maintain a charge to the hybrid battery system. When accelerating to speeds above 30 miles per hour or when traveling up inclines, the combustion engine’s rotations per minute (rpm) spiked, however the vehicle’s power-train still rapidly lost power and the hybrid battery drained significant charge. During one instance in November 2025, while attempting to accelerate to 55 mph up an incline, the hybrid battery drained enough that the vehicle was required to be pulled off the road to allow the battery to charge. During the April 2026 event, while containing a family of four (including to young children under six years of age), the vehicle failed to accelerate to 60 mph up an incline on an interstate freeway bridge. The vehicle rapidly slowed to between 20 and 30 mph, putting the family in grave danger from high-speed collisions. Following both instances, the on-board diagnostics computer was reset, “resolving the issue” and the Hyundai technicians elected to make no further repairs or replacements. The onboard diagnostics code P0191 was reported following the April 2026 event, however no codes or errors were identified by the Hyundai technician following the November 2025 event. No additional follow-up was performed, even though the vehicle remained under the manufacturer’s warranty.

I had stopped and put gas in for a full tank. Pulled out onto the Hwy heading towards Houston TX and was accelerating up to speed limit of 50MPH when the warning on the instrument panel displayed HYBRID SYSTEMS DISABLED pull over and stop immediately. Which I did, but I could not accelerate and was losing speed in traffic. I got safely parked and turned the vehicle off. I let the car sit for a few minutes and started it back up. All warnings were gone and the vehicle has performed normally since up to the current mileage of 9374. I took the vehicle to Hyundai today, 4/13/2026 and they hooked it up to the diagnostic system and it showed NOTHING.

Sudden loss of power (multiple incidences in the first 3000 miles, multiple service visits). While driving normally there was a sudden loss of power. Once at an interstate on ramp while attempting to merge, and three times while driving on city streets. The first dealer visit resulted in no action due to no codes and the problem not replicating. When I pulled into the dealer and shut off the car; I received an alert that the vehicle was officially transferred to me. When I restarted the vehicle, it operated normally. The consensus was that the vehicle was left in “dealer mode” and it was several days after I purchased the vehicle before the system was updated. The second insident was deemed to be a bad catalytic converter which was replaced by the dealer. The third incident was said to be due to a bad fuel rail sensor which also caused the catalytic converter from the second incident. The fourth incident occurred the day after the vehicle was repaired from the third instance. The vehicle was not safe to drive and was towed to the dealer, where it is today.

Vehicle experienced a loss of acceleration while driving. When pressing the accelerator, engine RPM increased significantly but the vehicle did not increase speed. The vehicle felt as though it was stuck in one gear and would not upshift or downshift. The issue was most noticeable while driving uphill, where the vehicle was unable to maintain speed despite full throttle input. This created a safety concern as the vehicle could not accelerate normally in traffic conditions. The problem has been progressively worsening over time. Initially there were mild symptoms, but it has become more severe and frequent, culminating in a near-complete inability to accelerate under load. No warning lights or messages were observed prior to or during the failure (if that’s true—adjust if needed). Vehicle has approximately 28,000 miles. The vehicle is currently at a dealership for inspection and diagnosis, but the issue has not yet been confirmed or resolved at the time of this report.

The 2025 Hyundai Santa Fe Hybrid has had multiple occasions, most recently on February 3, 2026 with 12,330 miles on the car, where the gas-powered engine fails to provide any power to the drivetrain. The car experiences vast power loss and enters "limp mode" where only the small hybrid battery is powering the vehicle. Max speed ranges from 10 - 25mph and there is little, if any, acceleration, even when the gas pedal is pegged to the floor. It is necessary to pull over, engage the flashing safety lights and try to find a safe place to park. After turning the vehicle off and on several times, eventually, the gas engines re-engages. The first incident of this type for this vehicle was on August 7, 2025 with approximately 4,400 miles on the vehicle. It was taken to the dealer, Key Hyundai of Salem, who could not find any DTCs and could not replicate the problem. They said "bring it back if it happens again." They next time was on February 3, 2026 where it happened several times on a trip to and from a local restaurant. This time, at DTC code of P088000 POWERTRAIN / POWERLOSS was recorded and reported. However, by the time the car was seen by Key Hyundai of Salem on February 5, 2026, the code has cleared itself. Hyundai's corporate policy is that historical codes can not be used for Warranty claims. So, the dealer tried one potential fix, cleaning the TCM connectors under the driver's seat, and returned the vehicle stating that Hyundai corporate would not authorize warranty work unless/until the car was presented to the dealership with a current / live DTC or visible broken parts. It seems unsafe to put a vehicle back on the road that could lose power and drivability at any time for no apparent reason. I am aware that there have been several other reports of similar POWER LOSS / LIMP MODE situations by owners of 2024-25 Hyundai Santa Fe Hybrids. At the moment, I am told that there is no current Technical Service Bulletin on this from Hyundai.

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.

Check emergency, stopping function alert. Check hybrid system stop safely. Both alerts came on the dash the steering wheel vibrated 11 other alerts popped up in the car steered me to the side of the road. It would not start again and This has happened four times in the 7 months I’ve had the car Hyundai cannot figure out what the issue is. In fact they tell me there is no issue because it’s not happening to them while it’s been there for almost a month.
