2025 Kia Sorento Hybrid

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.

In February, on my car that I had had for six months with less than 3500 miles on it, I was driving and got a “driver assist warning“ on my car and I no longer have the ability to apply gas to the car. Thankfully, I was able to pull over safely. I restarted the car and everything was fine. I called the dealership and they said it is probably a bad sensor and I made an appointment to bring in my card that Friday. They said that this was due to probably a dirty sensor due to it being snowing out. The next day I took my car to a car wash to clean it to make sure that there was nothing messing with the sensor. As soon as I exited the car wash, I got the same quote, driver, warning, assist quote, warning on my dashboard and lost the ability to gas my car. I immediately took my car to the dealer where it stayed for 18 days. They said that they replaced the sensor which was causing the issue. I had my car back for a total of 10 days when the same thing happened to me. This time I was driving on a 55 mph road. Luckily, again I was able to pull over safely. I took my car straight to the dealer where they had it for 28 days. They got the corporate Kia mechanics involved. They tried a bunch of things to fix my car, and eventually said that the sensor malfunctioning was due to the oil being too high. This is on a car now with less than 38,000 miles which has never had service on it. My car has been in the shop for a total of 46 days of the last two months. The sensor just going out abruptly can cause a major accident. Since I have had this problem, I have heard of at least two other cars doing the exact same thing.

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.

While travelling in the center lane of the highway, the vehicle experienced a sudden loss of power and could not maintain speed. Vehicle could not go faster than approximately 20 miles per hour. Managed to exit highway off ramp by driving approximately 20 miles per hour as there was not a shoulder to exit the lane of traffic in that particular area. The hybrid battery voltage went very low. After exiting highway turned off vehicle and turned back on again, was able to drive normally to the dealership service center. Dealership found code history of fuel rail pressure sensor, cleared code and test drove and stated not able to duplicate concern at this time. 2025 Kia Sorento Hybrid mileage is 14250 miles

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.

1. I'm not sure what component or system malfunctioned. The dealership has said something different every time it's had to be taken in. The first time they said it could have been the dip stick. The second time they said they didn't know but did an update to the car's system. Last week, was the third time we've had to take it in and they said they are doing an oil change and replacing the air intake hose assy, GDI fuel pump, High pressure fuel pump, valve cover assy, oil filter and oil but didn't say if this would fix the issue. 2. We have loss confidence in this car's safety and reliability and the dealership's ability to repair it. It's been in the shop multiple times and continues to fail. The issue with the vehicle is that when we got a warning the power to the car shuts off. It doesn't allow you to do anything with the gas pedal no matter what speed you are going. We have experienced this multiple times on city streets and the highway. The potential for an accident is very high when the car does this. 3. We have taken it to the dealership and they don't know what's wrong with it. I created a case with Kia and have not heard back from a case manager at all. 4. The vehicle has only been inspected by the dealership and no one else. They have contacted Kia corporate for solutions via messaging but this is the third time the car has just loss power while we are driving. 5. There were some warning signs like check hybrid batter system on the dashboard. The kia Access app allow shows diagnostic alerts like ADAS_DRV. I have attached some photos and some of the documentation we have. There have been multiple dates but I put the first date that the car broke down. Other dates include (1/28/26 and 2/6/26).
