2021 KIA SORENTO Complaints

Recall 22V-760 was performed, but the remedy failed, the exact same safety code has returned, and the manufacturer is refusing to replace the failed hardware component.

previous warranty repair for a failed fuel injector (RO #1103175) resulted in severe gasoline dilution of the engine oil. the vehicle now vents raw fuel vapors into the cabin (Fire Hazard) and hesitates/jerks when braking at stoplights (Stall/Crash Hazard). Kia Corporate has refused to communicate for over two weeks while the dealer holds the car.

I am filing this complaint regarding my 2021 Kia Sorento, which has suffered a transmission failure. The transmission slips, shifts harshly, hesitates during acceleration, loses power unexpectedly, and has become unsafe to drive. This defect has put my safety and the safety of others at risk. On several occasions the vehicle failed to respond properly when accelerating, including while entering highways and driving in traffic. The hesitation and sudden loss of power created fear and anxiety because I could not trust the vehicle to operate as expected. The problem has been reproduced and confirmed by a repair facility, and the symptoms are consistent with a transmission torque converter clutch failure. I also contacted Kia and provided the vehicle information. Kia informed me that they would not repair the vehicle because it has exceeded 100,000 miles and that the recall or warranty extension had expired. However, my vehicle is experiencing the same transmission-related symptoms reported by many other Kia owners.I never received any recall notification because I purchased the vehicle from a dealership as the second owner. Had I been properly notified, I would have taken the vehicle in for inspection much earlier or would never have purchased the dangerous vehicle in the first place. It is extremely frustrating and costly to be denied assistance solely because of mileage when the failure appears to be related to a known transmission defect.Before the failure, the check engine light illuminated and then went away even though the issue did not. Prior to that warning, the vehicle had already shown delayed shifting, slipping, hesitation, rough gear changes, and loss of power, which became progressively worse. I reported this to Kia on a previous service visit to Romeo Kia in Lake Katrine, NY and was told they did not find anything wrong. This situation has caused significant emotional stress and anxiety. I am requesting a full review and a fair resolution from kia. Thank

The vehicle experienced a sudden and dangerous loss of motive power while driving due to a failure of the 8-speed dual-clutch transmission's (DCT) high-pressure electric oil pump causing loss of shifting and dropping to lower gears at a very high rpm and slowing the car almost instantly creating a hazard for a crash with following vehicles. ?This vehicle was previously serviced under Kia Safety Recall Campaign SC250 (NHTSA ID: 22V-760). However, the initial recall remedy failed to permanently resolve the underlying defect. Despite the recall work being marked as completed, the transmission component has failed again.

I am filing this complaint regarding my 2021 Kia Sorento, which has suffered a serious transmission failure. The vehicle is displaying diagnostic code P0741, indicating a torque converter clutch malfunction.

The hesitation and sudden loss of power created fear and anxiety because I could not trust the vehicle to move when needed to avoid a dangerous situation.

The vehicle suddenly lost power when in drive or reverse but will idle fine in park or neutral.

The contact owns a 2021 Kia Sorento. The contact stated that while parking the vehicle, the vehicle jerked abnormally. The contact stated that while the vehicle was in drive, the vehicle jerked and unexpectedly accelerated while driving 55 MPH and was dragging. There were no warning lights illuminated. The contact stated that the vehicle was serviced by the dealer for a transmission failure, but the failure persisted. The contact stated that the manufacturer was made aware of the failure. The failure mileage was approximately 35,000.

The vehicle is suffering from a chronic, cascading powertrain and fuel management defect that has resulted in a critical safety hazard: sudden engine stalling. Over the last 17,000 miles, the vehicle has experienced three severe engine/emissions failures that the manufacturer has been unable to permanently resolve. At approximately 30,000 miles (on 29-Jun-2025), the engine suffered a severe Cylinder 3 misfire (Code P0303). At approximately 39,000 miles (on 02-Jan-2026), the unresolved fuel issue caused a failure of the Catalytic Converter (Code P0420) and an Evaporative Emission System leak (Code P0456). At 47,000 miles (Current Event), the fuel delivery system failed completely. The engine began running excessively rich (Code P2178), causing the engine idle to drop dangerously low (Code P0506). This defect caused the vehicle to suddenly stall out, resulting in a complete loss of motive power and leaving me stranded. Because the manufacturer's authorized repair facilities have only addressed the symptoms rather than the root cause of the fuel system failure, the vehicle repeatedly loses power and stalls without warning. This poses a severe safety risk to myself and other motorists, especially when operating the vehicle in traffic or at highway speeds.

My vehicle lost power and accelerated quickly yet unpredictably, and the check engine light came on. A local shop told me it was "an old code" for the transmission and that if it does that again to take it to dealer. It occurred again. Kia dealer states this vehicle has a recall and has been repaired twice, but that they will not repair it again. This is such an unsafe issue they will not allow me to drive the vehicle. I will have to pay almost $7,000 to replace the transmission.

Intermittently, when coming from a stop (stop sign, red light, etc) or recent start of the vehicle, the Sorento will not accelerate past approximately 30 miles per hour and the auto-stop light will flash orange in the panel. Once the vehicle is stopped, turned off, and restarted, it goes back to operating as it should and accelerates like normal. This has happened when driving on small, low speed limit roads and on large, high speed limit roads. My safety and the safety of those driving around me is put at risk when vehicles around me are expecting me to drive a certain speed but I can't and am looking for a safe place to pull over to stop and restart the vehicle. To date, the vehicle acceleration has not suddenly dropped from a high speed to a low speed thankfully, but when the issue presents itself, it will not allow the vehicle to accelerate above the 30mph range. The vehicle is available for inspection upon request. It is currently at a dealership that is working to reproduce and confirm the problem. There are Reddit threads that discuss other Sorento owners experiencing this same issue. To my knowledge, there were not any warning lamps, messages, or other symptoms of the problem prior to this issue presenting itself. It has been happening on and off for the last 1-2 years. My vehicle has not been inspected by the manufacturer, police, insurance representatives, or others but I am happy to have any of them do so. A simple battery replacement has not resolved the issue - it was happening before I had my battery replaced and it has happened since having my battery replaced.
