2025 Kia Sorento Hybrid

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.

This report concerns a repeating loss of power in the 2025 Kia Sorrento-Hybrid that forces the engine into "limp-mode". This issue has occurred when traveling at speeds exceeding 55mph on highway as well as when accelerating to merge into traffic. The vehicle does not flash any warning lights on the dashboard and shuts down in the middle of traffic which presents a serious safety issue for oncoming traffic as the vehicle must coast to the side of the road. This has occurred multiple times and twice I have had the vehicle towed to the dealership. Initially a fuel pressure sensor was replaced and the second time the dealership indicated they could not find any relatable cause. Since that time there have been two additional occurances that I have had. I believe the issues are related to either a fuel pressure sensor or a sudden loss of power within the EV system that causes the vehicle to protect itself by enetering into the limp-mode. I have discovered a short term resolution is to disconnect the 12-V battery and let the car sit for 30 minutes to clear the system codes, but sitting on a busy roadway and the loss of power at speed is a serious safety issue. I have spoken to other owners who have experienced similar issues so this appears to be a wider spread issue.

The contact owns a 2025 Kia Sorento. The contact stated that while driving approximately 75 MPH, the vehicle lost automotive power and failed to exceed 30 MPH. The contact pulled over to the side of the road to avoid other vehicles. No warning lights were illuminated. The vehicle was towed to a dealer to be diagnosed; however, the cause of the failure was not yet determined. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 16,386.

The contact owns a 2025 Kia Sorento Hybrid. The contact stated that while driving at approximately 55 MPH, the vehicle suddenly decelerated and failed to exceed 35 MPH before stalling and losing power. Emergency services were contacted and assisted with pushing the vehicle to the side of the road. The vehicle was towed to a dealer, who held the vehicle for two days but had not diagnosed the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 11,000.

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.

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.

The vehicle experiences a sudden and complete loss of power while driving. Specifically, the vehicle loses the ability to accelerate. During these incidents, the battery indicator shows critically low battery levels despite there being sufficient gasoline in the vehicle. The exact component causing the malfunction has not been identified by the dealership, as they report no diagnostic codes are present. The vehicle is available for inspection upon request. This issue has occurred multiple times while driving on highways at speeds where surrounding traffic is traveling approximately 55 mph or higher. This has also happened while pulling out into traffic, causing near misses of an accident. When the malfunction occurs, the vehicle rapidly loses acceleration capability and slows down to approximately 20 mph. This creates a dangerous speed differential between my vehicle and surrounding traffic. It becomes extremely difficult to safely maneuver into the breakdown lane due to the inability to accelerate. This situation creates a significant risk of rear-end collision or multi-vehicle accident. The dealership has been unable to reproduce the issue during service visits. However, the vehicle has been brought in multiple times for this same concern. The dealership has stated that no diagnostic trouble codes are stored, and therefore they cannot identify or repair the root cause. I have multiple videos documenting the issue occurring while driving. The vehicle has been inspected multiple times by the authorized Kia dealership service department. This issue has been occurring since July of 2025. Video Link: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Currently at a Kia dealership for the 3rd time since the end of December. While driving the electric refuses to switch to gas after the battery drains, it is a hybrid. Maxes out at 18 mph and then an alarm goes off for Hybrid System error. First two time check engine light also came on. Have had vehicle towed to Kia dealerships all three times. Never the same thing repaired or replaced but problem stops for a few days to two weeks and then happens again. They vehicle has been examined and the issue has been replicated or examined by the Canton Kia dealership in Canton, MI two times. Currently at Taylor Kia Toledo, OH. This is a safety issue due to the lack of speed and acceleration. So far I have been in relatively low speed areas but what if it happened on the expressway or in heavy traffic. I normally have my kids in the car and now feel that my vehicle is unsafe and I have only had it 11 months.

The contact owns a 2025 Kia Sorento Hybrid. The contact stated that while driving approximately 65 MPH, the vehicle went into LIMP Mode, and the vehicle decelerated to 35 MPH. The vehicle was driven to the residence and was later towed to the local dealer. While at the dealer, the cause of the failure was not determined, and the failure had self-corrected. The vehicle was retrieved; however, approximately 1,500 miles late,r the failure reoccurred. The manufacturer was made aware of the failure. The failure mileage was 2,300.
