2025 Kia Sorento Hybrid

While driving in a 55mph highway, I lost all accelerative power in my KIA Sorento Hybrid, driving my speed down to 25mph with vehicles behind me and no shoulder to pull onto. When I put my foot on the accelerator, the rmps on the dash would go all the way up 3000-4000 rpms, but there wasn't even a revving sound, and the car would not accelerate. Luckily I had just left my house was able to turn around and drive slowly home with my hazard lights on, the two miles back home. The first moment it happened the car behind me had to break, and luckily did so in time. From looking up the symptoms, it seems it may have been a malfunction with the HPCU. At no time did any diagnostic lights come on to alert of an issue. I shut the car off after returning home, tried to drive up my street, the same thing happened even when I tried to accelerate to 25mph. I am making an appointment to take it to a kia dealership.

My 2025 Kia Sorento Hybrid SX-Prestige has repeated issues with the engine and drive train. On December 30th, 2025 it was diagnosed with a blocked breather hose sensor, causing the check engine light to come on. On July 1, 2026, the car rapidly decelerated while driving on the highway (limp mode), creating an unsafe condition, with an alert to charge the battery. The car also seemed to struggle getting up to speed, and shifted gears less smoothly, and at higher engine RPMs than it had previously. The deceleration behavior was confirmed by the Kia Technician. On July 21st, 2026, the car again rapidly decelerated while driving on the highway (limp mode), creating another unsafe condition, but no alert to charge the battery was received. This time the fuel rail pressure sensor was replaced. The car is now sitting in my driveway, completely dead. I drove it 2 days ago, and nothing appeared amiss. Yesterday morning, the doors would not unlock using either key fob, so I used the physical key to enter the car. It would not start. My husband measured the voltage from the battery terminal (inside the fuse box under the hood) to the bolt on the wheel strut at ~3 Volts. No settings were changed in the car and I verified the headlights remain in "Auto" mode. As it is Sunday, I will contact the Kia dealer tomorrow for directions. Due to the repetitive nature of issues with this car, I would like help from the NHTSA to ensure this is promptly and permanently fixed.

I purchased a 2025 Kia Sorento Hybrid from Dulles Kia. Since I've owned it, I've had the same problem three times — my car randomly goes into limp mode while I'm driving. It doesn't matter what speed I'm going. The car just starts slowing down on its own, won't let me accelerate, and the RPMs start surging up and down. It's terrifying. The first time it happened, it was towed to Fayetteville Kia. They couldn't even recreate the problem. They redownloaded some software and sent me on my way. The second time it happened, it was taken to Herson's Kia in Rockville. This time they were able to recreate it. They told me it was the fuel pump and replaced it under warranty. Now it's happened again — this time while I was on vacation in Ocean City, Maryland. I was stranded with my two dogs, one of which is my service animal. I had to arrange a tow and find a last-minute hotel out of pocket. The car is currently at Pohanka Kia in Salisbury. They first told me it was a fuel injector, then changed their diagnosis to a valve seal issue — and apparently it's a known issue with this type of vehicle. It has now been sitting at the dealership for over a week. This is the third time the same problem has occurred. It has ruined multiple vacations and left me stranded, stressed, and without my car for extended periods. I just want a car that works.

For an unknown reason when driving on the highway in heavy traffic the engine started to shake violently causing us to immediately pull over and when we opened the hood the engine was shaking violently. This was a dangerous situation because during this time the engine was not very responsive to input. No warning lights came on at all.

My 2025 Kia Sorento Hybrid, with approximately 20,000 miles, has experienced a sudden loss of power and entered a limp-mode condition twice within two days. During both incidents, the vehicle would not accelerate normally and was unable to maintain expected traffic speed, creating a significant safety hazard. No warning lights, warning messages, or check-engine light appeared before or during either event. After the incidents, no OBD-II diagnostic trouble codes were present. Stopping and starting the vehicle restored normal operation temporarily, but the problem reoccurred. The sudden and unexplained loss of propulsion without any warning or stored fault codes increases the risk of a crash, particularly when merging, passing, or driving in traffic.

Around XXX the car was suddenly unable to accelerate properly. When pushing the accelerator, the engine would rev only after a long lag, would rev significantly higher than normal without shifting, and the acceleration response was dramatically less than usual. It felt as if the engine simply had no power, or at times almost as if something were resisting the engine. It made it nearly impossible to accelerate past roughly 40mph and the response in acceleration from the pedal was very unpredictable. A mechanic was able to replicate the issue and it was initially attributed to the high pressure fuel pump. Roughly a week after the pump was replaced in early August 2024, the issue occurred again and was again replicated by the dealer and attributed to the fuel sensor, which was replaced. The issue then re-occurred on June 14, 2026. The car is currently in the shop awaiting diagnosis and repair. At no point during any of these instances did any warning appear on the dashboard or anywhere else in the car. The parts are not available for inspection, it is unclear to me who from Kia or any other organization has examined them beyond the dealership (Kia of Riverdale in Riverdale, NJ). The safety of the car’s occupants and potentially other motorists was put at risk by acceleration performing radically differently than would be anticipated from a properly functioning car. The issue was noted several times, including while pulling out of a parking lot onto a busy road and while attempting to keep up with traffic on a busy divided highway.

1/24/26 -- While driving ~25-30mph (~2 miles from start of trip) car produced “Engine Management System error” and within a minute or so “Check Hybrid System. Stop Safely” warning and went into electric only mode, limp mode. Turning off the car and turning back on temporarily enabled the gas engine to run. Dealer reviewed fault codes and stated vehicle was now running correctly. ~800 miles and less than 30days later the same problem occurred again. 2/17 – While driving ~30mph (~1mile from start of trip) the car produced a “Engine Management System error”. At this point I was approaching a traffic light and stopped at the red light. Decided to return home and attempted to turn right on red at the light. When I hit the gas to turn, the gas engine did not engage, the car limped forward a few feet in electric mode, and the car started beeping with the “Check Hybrid System. Stop Safely” warning. If I had less less space when turning right, or the car would have a moved a few feet farther, I would have been hit in the intersection by an oncoming car. Thankfully I had left a lot of space and my car did not pull that far into the intersection. I turned the car off, when I turned the car on again, the gas engine engaged, and I was able to slowly drive the 1 mile home. Car was then towed to the dealer 2/18 for repair. As of 3/17 dealer still has the vehicle (so do not have a second repair invoice) and waiting on an Customer Care escalation from KIA as dealer recalibrated the Hybrid module but can't recreate the issue after driving 400miles. This issue leaves the car in a limp mode with a significant chance of causing a accident, I was almost hit, when there is loss of ability to accelerate at any meaningful rate or drive any sustained distance.

Incident #1: Car suddenly and without warning had complete loss of power, with gas engine shutting off and only using battery power. Car was traveling at 45mph in morning traffic. Pedal was pushed to the floor, but car would only go a maximum of 20mph. Warning dash lights then appeared saying "Hybrid Malfunction/Pull Over Immediately/Turn off car". I was able to pull off road and turn off car and then turn back on. Car ran normally the 2 miles back home. Incident #2: 2 days later, while driving my kids to school the car again, suddenly and without warning had complete loss of power, with gas engine shutting off and only using battery power. Again, warning dash lights: "Check Hybrid System. Stop Safely!". I did so and car ran normally back to my house (distance approx: 2.5 miles). I immediately called KIA of Beaverton and they said to have it towed right away. Once at dealer, they were unable to diagnose any issues and said that no codes showed up, but also said that the car "deleted codes". Car was in shop for 2 days and determined "car operates as designed." I picked up the car. Incident #3: 7 days later, with kids in the car, again car had complete power loss with no warning. Warning lights again told of "Check Hybrid System. Stop Safely!" Pulled over (in heavy Friday rush hour traffic) and turned off car. Turned on again, but this time car drove for less than a quarter mile before complete power loss happened again with all warning lights. This time we took video of the car not having power, all the warning lights etc. as evidence. We turned off the car and upon turning it on, it instantly had no power. We pulled car over and had to park it that night at a local business for towing. Car was towed again to Beaverton KIA. Again, dealer said they were not able to replicate problem after driving 250 miles on it. Insisted we pick up car, despite numerous comm's saying how unsafe we felt taking it. Dealer claimed KIA told them to remove .5 Qt of oil.

While driving, have had the engine of my 25 Sorento Hybrid stop working. An emergency notice comes on the screen (see photo) stating to pull over safely. The hybrid system error message has come on 4-5 times in the last month. The vehicle will not drive more than 15-20 miles per hour and has virtually no acceleration making it very dangerous to drive in or around high speed/traffic areas. Took it to a local Kia dealership where I was told nothing was wrong and their only guess was that it was related to the battery and cold weather. The same messaged/incident has happened 2x since bringing it into the dealership. With the most recent being 1/22/26. Problem first arose on 1/9/26. There are dozens of reports of this in online threads over the past few months with Kia hybrid engines
