This Problem Across All Years
My wife first drove the vehicle and started noticing intense fumes entering the cabin which required rolling down the windows. There were no alerts from the car at this time or engine lights. We checked to see if the exhaust got plugged and it was not. I later drove the car that same day and it would not accelerate when I tried to right turn onto a main road. The check engine light then popped on and loud alerting from the vehicle cause me to have to pull over and shut the vehicle off. We had it towed by the dealer and the last thing we heard was that gas and oil had leaked together and it would take 5 days to get the part to fix it.

Will be driving when it switches to EV mode it will have no power and go into limp mode. Can't go over 30 mph. This is now the second time this has happened. Dealership tried to say it was because of temperature. Come on.

Beginning at approximately 750 miles on a brand-new 2025 Kia Sorento Hybrid EX, the vehicle experienced a flashing Check Engine Light accompanied by severe shaking while driving, rough idling, loss of power, and loud engine/exhaust noise. The vehicle became difficult and unsafe to operate due to the vibration and reduced drivability. These symptoms appeared suddenly on November 22, less than three weeks after purchase. The vehicle was taken to the dealership on November 24. Their technician retrieved diagnostic codes P0300 (Random Misfire) and P0304 (Cylinder #4 Misfire) and identified a failed ignition coil on Cylinder #4. The coil was replaced, and the dealership reported the issue resolved. However, less than 24 hours later, with the vehicle still under 800 miles, the exact same symptoms reoccurred: heavy shaking while driving, vibration while idling, loss of power, and unstable engine operation. This indicates the underlying issue may be more serious than a single coil failure. The problem has been reproduced and confirmed by the dealership, and the vehicle is currently back in their possession for further inspection. A loaner vehicle was issued because the vehicle was not safe to drive. The sudden shaking, engine misfire, and loss of power created a significant safety risk, especially if this failure were to occur at highway speeds or while turning across traffic. Given the extremely low mileage and recurrence immediately after repair, this may indicate a broader defect affecting engine performance or ignition components in this model. The vehicle remains available for inspection by NHTSA, the manufacturer, or investigators.

Dad, driving back with Daughter, noticed a brief and unusual delay between shifts, but was able to make it home fine. A few minutes later, Mom left for picking up Son after school. On the way there, she noticed sluggish acceleration, louder engine sounds/effort on acceleration and mild slopes, and there was a lag in acceleration response. After powering off the vehicle and sit in idle to recharge battery, restarted trip home and was unable to get acceleration response up the hills, doing only 20 MPH. Engine was struggling and not getting any acceleration response. No check engine lights were generated as usual. Dad called Service Manager at Kia Temecula and he said to call Kia Roadside Assistance to come tow the car to them. He also said that likely we'll be out of pocket to do any car rentals until they have a car to loan to us.

While driving my 2025 Kia Sorento SX Hybrid on a normal hot day, I experienced a sudden and dangerous loss of power. I had briefly exited the freeway to pick up my children and left the vehicle running. After re-entering the freeway, the car failed to accelerate despite pressing the gas pedal to the floor. It felt stuck in first gear, with the engine revving but no response. The hybrid battery showed nearly empty, and the car would not switch properly between electric and gas modes. A warning appeared instructing me to “park the car and leave the engine on to charge the battery,” which I did. After idling for several minutes, I slowly drove—with hazards on and speed under 25 mph—to the nearest Kia dealer 1.5 miles away. This incident could have been catastrophic if it occurred while merging into traffic. The dealer has been unable to replicate the issue and is offering no fix. This was a sudden hybrid system failure with no warning lights or prior symptoms. It severely affected drivability and put my family at risk. After researching, I found that multiple other owners of 2025 Kia Sorento Hybrids have reported similar power loss incidents since May 2025, especially during warm weather. This is a serious safety issue. A car that unexpectedly loses propulsion—especially while merging or accelerating—can cause a major crash. I urge NHTSA to investigate this defect in the hybrid system and issue guidance or a recall before someone is injured or killed.

On June 5, 2025, I was driving my 2025 Kia Sorento. I proceeded to get onto the highway from an on ramp. At that moment, the engine stalled. The car would not accelerate. I could not go faster than 20-25 mph. This was a huge safety risk to me, to my passengers, and to others on the highway. Eventually I exited the highway and drove home very slowly, since the car would not accelerate beyond 20-25 mph. I was pressing the gas pedal as far down as it would go. I even tried turning off the car and restarting it. The check engine light was on. The car was towed to a Kia dealer. The Kia mechanics noted that the fault log in the car's computer system noted that the stalling/failure to accelerate event did occur, but that they were unable to reproduce it, even after several attempts driving it around in various conditions. The Kia mechanics told me there was nothing they could do or fix, since they were unable to reproduce the stalling event. Then just yesterday, on July 6, 2025, the Sorento stalled again while it was being driven on the highway. I am having it towed tomorrow to the same Kia dealership to have the same mechanics look at it again. At this point, this is an extreme safety issue for anyone driving the car, in the car while it is being driven, or on the highway when the car is on the highway. Imagine if the car stalls again and another car behind us traveling at a high speed slams into us. We could potentially suffer mortal or grave physical injury.

I pulled out of my subdivision and immediately received an error check engine light warning and initially didn't think much of it. As I pressed the accelerator I noticed there was no engine power at all just electric (this is a Sorento Hybrid SX Prestige) so I immediately pulled over and turned the car off for two minutes. Upon turning it back on the engine did rengage so i decided to proceed. About a mile further the same check engine error occurred with the engine not responsive at all and only electric power available so I made a u-turn and proceed back to my house. Prior to arriving at my house another warning error appeared warning me the electric battery was dangerously low and to stop the vehicle immediately. I believe the error was a Hybrid system error with code P112000. Once again I turned the vehicle off and waited 2 minutes with the engine reengaging. I had the car towed to the dealer where it sat for 3 weeks. Their response was they couldn't reproduce the error so had no idea how to proceed to fix the issue. That is unacceptable to me since Kia programmed the car in the first place they should be very aware. I have had two cases open with Kia where they are refusing a solution and my request to buy back the vehicle. I have had another case with KBB Auto and they likewise refer to the WI state lemon law. I have clearly communicted to them that I don't feel safe driving this vehicle any longer and they need to take action for all consumers but that is falling flat. My safety and that of others is being put at major risk here as if this error occurs in situations such as pulling into heavy free flowing traffic or on a busy freeway where the engine doesn't engage many lives are at risk. There was no attempt to fix the vehicle at all. Just reset the error and told me to come get it. Let me make it clear here...the vehicle is working but hidden somewhere in the software is a major programming glitch. Please help!
