2025 Hyundai Santa Fe Hybrid

The vehicle has gone into a limp mode unexpectedly while driving on the highway at 60+ mph. The first issue was on May 13, 2026. The car immediately stopped driving and went into limp mode and cannot go over 30 mph. It was taken to a service dealer. They could not replicate the problem, therefore the vehicle was given back as undiagnosed. This next incident occurred and almost caused an accident, and that was on June 3, 2026, again driving on the beltway around Maryland. The car went from 70 mph to 30 mph. The vehicle stayed at 25 to 30 mph the entire time. Could not get it to do anything else. Drove cautiously on the side of the road and got to the dealership after driving 30 minutes at 25 mph.

Sudden loss of power while driving on the interstate (65 MPH) , car would no longer accelerate and slowed down to ~10 MPH. Had to merge onto emergency lane, car struggled to power over 30 MPH. Warning light came up to "Park with engine On to charge battery". Parked car and restarted car and still did not resolve issue. Had to switch the car into "Sport" mode to drive home.

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

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.

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.

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.

Gas Motor is not engaging to assist electric drivetrain on a hybrid AWD 2025 Santa Fe. This resulted in a dangerous situation crossing a busy road from a stop sign. The Santa Fe rolled into the intersection at the drivers request, but did not accelerate normally (only to a maximum of a few miles per hour) and felt like an eternity to cross the road. Fortunately oncoming drivers from left and right were paying attention and slowed down and in one case honked aggressively to point out we driving badly. Pulling over to the side of the road, turning the vehicle off and then back on again has sometimes made it run normally, but we limited our trips at that point to first getting safely home and then delivering it to the dealer. The 20 mile drive to the dealer required pulling over twice to reset the vehicle so the electric motor would assist. We have had repeated warnings from the onboard system including "Follow up checks required - Engine Management System" and "There may be a problem with the engine management system Contact your Dealer". I will note that we have 11,000 miles and 11 months experience with the vehicle with NO problems. It may not be relevant, but these new faults began 2 days routine service for oil and tire rotation when recall was performed including ECU Software Update for Recall 25-01-028-1. Dealer is uncertain of problem and referring with outside tech assistance from Hyundai but we were told to expect 2 weeks for parts and repair and uncertainty as to whether that would fix it. In the meantime a vehicle with unreliable acceleration and top speed is unsafe and parked. I do note on this NHTSA website 2025 HYUNDAI SANTA FE HYBRID SUV AWD that there are 47 Complaints. 9 relating to this problem all beginning October 2025 and none prior back to the first post of Nov 2024 for this model. Complaints similar to this for engine management and speed and power loss account for 50% of complaints for this vehicle on the NHSTA website since October 2025.
