**What component or system failed, and is it available for inspection?** The vehicle's electrical/power system failed, causing a complete loss of power while driving. This is the fourth occurrence of this failure. The vehicle is currently at the Hyundai dealership and available for inspection. **How was your safety or the safety of others put at risk?** The power failure occurred while driving on a busy road. The driver struggled to safely maneuver the vehicle (executing a U-turn) to get out of traffic and reach a safe location. The vehicle had to be towed as a result. **Has the problem been reproduced or confirmed by a dealer or independent service center?** The vehicle has been brought to the Hyundai dealership for this same issue four times. As of the most recent update, the dealership has not been able to identify the root cause or confirm a fix. **Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others?** The vehicle is currently with the Hyundai dealership (manufacturer-affiliated) for the fourth time for inspection related to this issue. No inspection by police or insurance has been reported. **Were there any warning lamps, messages, or other symptoms prior to the failure, and when did they first appear?** There were no warning lamps, messages, or other symptoms prior to the failure. Warning lamps/messages appeared only after the vehicle lost power.
NHTSA complaint #11764110 — an unverified report by a vehicle owner.
While driving, the vehicle suddenly lost motive power on the highway and would not accelerate beyond approximately 20 mph despite accelerator input. There were no warning lights or check-engine light. The condition created a safety hazard because the vehicle could not maintain normal traffic speed. Hyundai dealer has been unable to determine the cause on other vehicles with the same problem, and was trying to discourage me from reporting this. They also said that they'd keep the car for 3 days, and likely return it with no diagnosis, so do I really want to go through this? They seemed unconcerned that this is a very dangerous issue in a highway.

I've had this vehicle for 13 months, and it has roughly 13K miles on it. Since 7/3/26, it has been in the service department at Hyundai of Noblesville on three separate occasions. This all started on 7/3/26 when we were driving on the interstate and out of nowhere the vehicle lost critical power and would not go more than 20 MPH. There was some kind of warning message that momentarily popped up but then disappeared. We were so rattled, we didn't get a chance to take notice of what it said. It was towed to the dealership and they said they cleared the codes and drove it a little and the problem was resolved. It was driving OK and then on 7/15/26, we had just got onto the interstate and there was a sudden loss of power AGAIN. We had it towed to the dealership. They replaced the high pressure fuel pump and assured us that the problem was resolved. Then on 8/29/26, the same thing happened again on the interstate--critical loss of power. Had it towed to the dealership again. This morning, they say that it is the fuel pump railings that are the issue. I have placed a formal Hyundai Corporate Case and I am notifying you of this safety issue which presents major risk to the safety of anyone in the car.
NHTSA complaint #11760870 — an unverified report by a vehicle owner.
When traveling home from work 8/27/26, my cruise control shut off and my car immediately went into “limp” mode. This almost caused me to get into an accident with a tractor trailer, in which, I may not have survived. Immediately pulled over and tried to find out what had caused this and how to get it fixed. Nothing worked to get it out of “limp” mode. There were no warning lights or messages, except LV3. Which was a completely different issue. This issue I was able to correct. Tried fixing the “limp” mode issue by doing as told by Google AI, turn car off, lock door with key fob, waiting 10-15 minutes for computer to reset. NOTHING. Also tried checking to see if there was a battery dump, in which this case would have been the fuel system not communicating with the hybrid battery system, NOTHING. I do have an appt with the dealership on 9/2/26 to have this looked at and inspected. I have not tried to start and or drive the car again, since. Do not want to be blamed by the dealership or manufacturer, that I did something wrong or caused more issues.
NHTSA complaint #11760351 — an unverified report by a vehicle owner.
Our family was driving on the highway at 55mph (I-495 in Alexandria, VA), the car instantly began to decelerate, despite having my foot completely on the accelerator and we had to limp over to the side of the road onto the shoulder. We had to wait multiple times for the hybrid motor to re-power itself to get off an exit at 10-15 mph. The car is now in "limp mode" and will not drive above 35 mph. This is the 4th time that we have had the same issue occur. Hyundai has provided a different fix each time, but they have yet to find an answer as to why this instant loss of acceleration keeps occuring. In the wrong circumstance. This instant loss of acceleration could be deadly and cause severe injuries to the individuals in the vehicle.
NHTSA complaint #11758911 — an unverified report by a vehicle owner.
On XXX, at approximately 6:30 PM, my wife was driving our 2025 Hyundai Santa Fe Hybrid on [XXX] when the vehicle suddenly lost propulsion power. It would not accelerate past approximately 55 mph. With the accelerator pedal pressed fully to the floor, the vehicle did not gain speed. I drove the vehicle myself the same day, immediately after she arrived home, to verify the problem, and I reproduced the identical condition. The vehicle accelerates normally from a stop, but at approximately 40 to 50 mph it stops accelerating and will not exceed approximately 50 to 55 mph regardless of accelerator input. No warning lamps illuminated and no messages appeared on the instrument cluster before, during, or after either event. The vehicle health check in the official Hyundai application reports the vehicle status as normal. The driver receives no indication that anything is wrong. This is a serious safety hazard. Sudden inability to accelerate in traffic creates a substantial risk of a rear-end collision and makes it dangerous to merge onto a highway, pass, or clear an intersection. Because there is no warning, the driver cannot anticipate it. The vehicle has approximately 13,741 miles and was purchased new on XXX. Scheduled maintenance was performed at the selling dealer on XXX at 7,924 miles. The vehicle has not been driven since XXX and is available for inspection on request. It is scheduled for dealer inspection on XXX. The problem has not yet been reproduced or confirmed by a dealer. I am aware of numerous owner reports of a similar loss-of-power condition in 2025 Santa Fe Hybrid vehicles in which the gasoline engine reportedly fails to engage and the vehicle operates on hybrid battery power alone. In several of those reports the trouble code cleared itself before the dealer inspected the vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1.Fuel did not activate on this hybrid while in stop and go traffic when apparently the battery died. There was plenty of gas in this brand new car. The entire car died, gas pedal inactive, on the freeway just when traffic opened up with red car/exclamation point indicator on dash. After power cycle car Its message said something like “pull over and charge car in park”. We were close to shoulder so were able to do as instructed. 2. Car died suddenly in freeway traffic w 4 passengers inside. Could have been rear ended. There was no information in manual, on line or through BlueLink app on the battery function, this particular message or the problem. Or criteria that causes car to fail without switching to fuel. 3. Days later when I could get an appointment, The Escondido Dealer did diagnostics, visual and test drive and found nothing. Dealer had no means to look back at history to ID fault codes at time of event. I had exact time/miles. They did not check battery as the diagnostics were clean. Complaint made w Hyundai consumer affairs. [XXX]. Case XXX. They could not tell me criteria or specifications for message to pull over. They could not direct me to battery or “switch to fuel” criteria. They are working on case. I fear a software bug or engineering issue. A non plug in hybrid should function on gas if battery cannot work. 4. No insurance claim or police notified 5. There were NO warnings prior to the car dying. The Car died w red exclamation in red car indicating service right away. We put on flashers & We power cycled and words came up on dash stating something like “pull over and charge car in park” Engine temp was good as we watched it. We pulled over and car was functional within 10 min. We drove home without any further issues. Car had 1345 miles total at incident. Brand new car. Less than 2 mos old and we started trip w ~297miles. I was unable to get photo of warnings as they happened. Just after while sitting in traffic.

NHTSA complaint #11752967 — an unverified report by a vehicle owner.
The vehicle will not accelerate past 30 mph on the highway. The fuel system will not engage, and the vehicle continues to run on hybrid mode which causes the battery to drain and acceleration to throttle. This occurs on all drive modes and fuel conditions.
NHTSA complaint #11750021 — an unverified report by a vehicle owner.
While driving on the freeway at approx 65mph, the car suddenly starting de-celerating and forced me to pull over to emergency shoulder/lane and try to determine the cause. The car is a "Hybrid" and the dashboard stated to put car in Park and Idle the Engine over 2000rpm to charge up the Battery. ( i still don't know which Battery they were speaking of...Engine Battery or Hybrid Battery) I sat there Idling the Engine for 15 minutes and slowly proceeded to get off the freeway and limped the car back to my home. I then called my selling Hyundai Dealer, as the car was still in warranty, and told them of my sudden problem and asking them what could it be??? They said they did not know until they saw the car and tested it with their computer equipment...please have it towed into their shop. So i did and 2 days later they called to say..NO Computer Codes showed any problem. They could not duplicate problem. I said ..."look on the internet...many people have reported sudden lack of power and limp mode activation....all pointing to the High Pressure GDI Fuel Pump Assy failure". Dealer said ..Oh..thanks we will look into that. 5 hours later Dealer called and said I was right, we replaced the Fuel Pump and come pick up the car. 4 months later and 6,000 miles later car is performing normally. I felt compelled to come forward to discuss this part failure as this incident on the freeway could have turned into a tragedy. Thank you
NHTSA complaint #11741374 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11740281 — an unverified report by a vehicle owner.
Since February 2026 I have had daily incidents of the hybrid system error where the vehicle is only relying on the hybrid battery to move. I've had a few near miss accidents as my car crawls through an intersection. Was almost rear-end after leaving a stop sign and the hybrid system error popped up and the car doesn't accelerate. In order to temporarily fix the system, the car must be shut off and restarted. There is not always a safe place to be pulled over to perform this shut down. It is a driving hazard and not safe to drive. It has been to the shop now a 3rd time with no resolution. I have reached out direct to Hyundai Corporation with my concerns and they have documentation. The car is a 2025 model and has less than 5,000 miles. I fear a serious accident from this system error and Hyundai needs to resolve ASAP.
NHTSA complaint #11733192 — an unverified report by a vehicle owner.
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.

Original letter to Hyundai below. The car is currently at a dealer again for repair of the same issue. Fuel pump replaced in Nov 2025 but issue has returned in March 2026. Videos of the issue recently occurring are available. Good morning, We had our 2024 Santa Fe Hybrid lose power while merging onto the freeway in November 2025. I was pressing the accelerator and it did not do anything, just kept rapidly decelerating. Pulled the car to the shoulder and turned it off completely and back on, and the car started up with the engine running which was unusual- typically the car starts up in silent electric mode. It would not accelerate past a few miles per hour. This has now happened on multiple occasions, disappearing for a few days only to return. It has gotten very dangerous to lose speed and acceleration into a busy freeway and almost caused an accident yesterday. We were thankfully close to a dealer (Glassman Hyundai in Southfield, MI) and were able to limp it a mile down the shoulder at low speed to drop it off. However, they are telling us they have no loaners available to provide us which seems unacceptable with a car under warranty with 18k miles on it. Is there anything you’re able to do to assist? Are there any known fixes for the issue that can be reported to the dealer? Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11730044 — an unverified report by a vehicle owner.
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.

Vehicle went in to limp mode in the middle of driving. Would not accelerate past 30mph. Was able to turn around and pull in to a neighborhood when the vehicle stopped responding altogether and had an additional warning about letting the engine recharge the hybrid system. Restarting the car got it home. This would have been extremely dangerous had it happened on the highway, at highway speeds. Dealership replaced the high pressure fuel pump. Got it back yesterday, we will see if that fixes it.
NHTSA complaint #11720923 — an unverified report by a vehicle owner.
Own a 2023 Hyundai Santa Fe Hybrid and have experienced the following issues over the past year and a half. Beginning after maybe 40,000 miles we pulled out onto a roadway and the engine immediately lost power and started flashing a glaring red warning that the hybrid system was failing and to pull over. We luckily were able to and turned the car off and waited. I tried to turn it on and it came back to life as if there was never an issue? We drove off. it left no warning code or did not update my Bluelink App. I took it to the dealership and they could not find any issues. Fast forward another 5 or 6 months and it happens again. Take it to the dealer and they keep it a week to go over it but still nothing. Within a week of getting it back it happens again and this time I am videoing it happening to me. Back to the dealer and provide the video because again the car did not log the event nor did it update my app. They hold it again for a week and try different things. They still cannot figure it out and I get it back.... it happens again.... This time the dealership was able to come up with an answer and that the oil level was too high. I got the car back and it seemed to work. Probably now 6 months go by and then this week I drive over to Jacksonville (5 hr drive) and visit. Again the car scares us on the highway and I have to pull over. Havea friend meet us with tools and we jack up the car and let out enough engine oil to insure we can read between the two marks on the dipstick. We drive off but the engine keeps hestitating and we almost make it back before it completly shuts down. We tow it to the Dealer in Jacksonville. They call the next morning like they can't find anything wrong! I explain everything and remind I don't tow cars for fun - something is wrong with the car and it is leaving us vulnerable and worst is it is not leaving any codes. Not sure but I have lost faith in Hyundai
