The transmission in my Kia Sorento intermittently does not engage when shifting from park to drive. It will take 5 to 10 seconds for the gear to engage. When this occurs, the car is free-wheeling and will roll away. This is especially dangerous if you are on a slope or hill. I of course am applying the brake when shifting out of park, but their is no warning or indication that the transmission is, or isn't engaged. I have mentioned this problem when visiting the Kia dealer, but no action was taken.

Kia completed Recall SC250 via a software update only. The physical hardware has now failed (Code P193B). Kia Corporate and the local dealership are refusing to honor the safety recall remedy because the software update marked the recall 'complete,' leaving a failed, dangerous transmission unaddressed.

I own a 2021 Kia Sorento 2.5L Turbo AWD with approximately 150,000 miles. In the evening, while driving home after dinner with my daughter in the vehicle, I was traveling in the area of [XXX] and [XXX] when the vehicle displayed a “STOP SAFELY IMMEDIATELY” warning. The vehicle unexpectedly slowed down/appeared to brake on its own while I was driving. There was no check-engine light at that time and the warning did not remain on, so I did not initially know what caused the incident. Approximately two weeks later, the vehicle developed delayed shifting from 1st to 2nd gear. RPM increased from about 2,000 to 3,000 before the next gear engaged. Switching from ECO to Comfort mode initially seemed to help, but later that day the problem worsened even in Comfort mode and also began occurring from 2nd to 3rd gear. The check-engine light then came on. O'Reilly Auto Parts scanned the vehicle and reported codes P0868/P086800 (Transmission Fluid Pressure Low) and P193B79 (High Pressure Electric Oil Pump Performance). Kia has not yet diagnosed the current problem, and the vehicle is available for inspection. Kia checked my VIN for recalls sometime in 2025 and advised there was no open recall. I am aware of Kia Safety Recall SC250/NHTSA Recall 22V-760 involving the 8-speed DCT electric oil pump on certain 2021-2022 Sorento vehicles. I am concerned because my vehicle experienced the “STOP SAFELY IMMEDIATELY” warning and unexpected slowing and now has worsening transmission symptoms and related diagnostic codes. I am concerned the vehicle could unexpectedly lose drive power while being driven. I request NHTSA review whether my vehicle's condition may be related to the existing safety defect and whether additional vehicles should be investigated.

Vehicle: 2021 Kia SorentoCurrent Mileage: Over 100,000 miles (Original Owner) Description of Safety Defect & Failed Recall Remedy: Background: This vehicle is equipped with the 8-speed Dual-Clutch Transmission (DCT) and has suffered from severe slipping, jerking, and hesitation since delivery (at 5 miles). In 2023, the vehicle received the software update remedy under Kia Safety Recall SC250 (NHTSA Campaign 22V760) for the defective electric oil pump circuit board. The Failure: The 2023 software patch failed to resolve the underlying physical safety defect. An independent technician recently diagnosed the vehicle and confirmed a permanent, un-clearable fault code for a completely failed electric transmission oil pump—the exact physical component failure targeted by safety recall SC250. This defect causes an immediate risk of a sudden loss of motive power. The Dealership Violation: The vehicle was dropped off at Greenway Kia West Orlando on Monday, August 17, 2026. The dealership held the car for over a week, logging it under a separate fuel pump recall to stall. On August 25, 2026, the dealership formally denied safety recall coverage and issued a $7,000 out-of-pocket quote to replace the transmission, claiming the vehicle is no longer covered because it is past the 100,000-mile powertrain warranty. Federal Mandate Violation: Under federal law, safety recalls do not have mileage caps. The manufacturer's remedy failed to permanently correct a documented safety hazard, and the dealership is actively attempting to shift a multi-thousand-dollar safety recall replacement cost onto the consumer.

The transmission pump on my transmission just went out randomly last week. The power in my car went into limp mode and the car won't drive properly now. The car was being driven at the time this happened, and my husband had to pull over, as the car wouldn't work. I had this looked at by an auto body shop and they diagnosed it with this, which is to be found that there is a recall on my specific year and model of car for this issue as well. For about a month prior, we had noticed a few "stutters" when driving the car. After I hit 100k miles on the car, it was doing it almost daily.

The contact owns a 2021 Kia Sorento. The contact stated that while driving at an undisclosed speed, the vehicle failed to shift gear as intended, and the RPM was extremely elevated. The failure had occurred on several occasions. The contact pulled over, and the message "Possible Condition with the Transmission Control System Detected - Press SOS for Roadside Assistance" was displayed on the instrument panel. The vehicle was towed to a dealer where it was diagnosed and determined that the transmission needed to be replaced. The contact researched and was made aware of an unknown recall; however, the VIN was not included. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 116,000.

On August 15, 2026, while operating my 2021 Kia Sorento, the transmission warning light came on and the vehicle displayed the following warning on the infotainment screen: “A possible condition with your Transmission Control System has been detected. Please press the SOS button on the rear view mirror or roof console for Roadside Assistance.” At the time of the malfunction, my vehicle would not properly switch gears. The transmission appeared to become stuck and would not shift as expected. This created a serious safety concern because I could not rely on the vehicle to change gears or respond normally while driving. The component/system that appears to have malfunctioned is the transmission and/or Transmission Control System/Transmission Control Module (TCM). The vehicle is available for inspection upon request. The problem first occurred on August 15, 2026. Prior to this occurrence, I had not received this specific transmission control system warning. When the problem occurred, the transmission warning light illuminated and the vehicle displayed the transmission control system diagnostic message described above. As of the filing of this complaint, the vehicle has not yet been inspected or diagnosed by a Kia dealership or independent repair facility. I have photographs documenting the warning message that appeared on the vehicle's display. I am concerned about the safety of continuing to operate this vehicle because an unexpected inability of the transmission to shift gears could cause a loss of acceleration, an inability to maintain appropriate speed, or an inability to safely maneuver the vehicle in traffic. I am also requesting that NHTSA review whether this failure is related to any existing recalls, investigations, technical service campaigns, or known transmission/Transmission Control Module issues affecting the 2021 Kia Sorento, including vehicles equipped with the 8-speed dual-clutch transmission.

My car will randomly go into limp mode and I am unable to accelerate. The auto stop/start light will flash orange on the dashboard. I need to pull over and restart car and it seems to reset. I see there is a recall for a 2021 KIA Sorrento but I don't think it affected my vehicle even though the issue is exactly the same. Recall #22V6000. It happened once a few months ago then didn't reoccur until about two weeks ago and it has happened three times since. It is scary because I am afraid to cross traffic in fear that the car won't move fast enough

"The vehicle has twice suffered a sudden, catastrophic loss of motive power at highway speeds (approx. 70 MPH) on the interstate, forcing the driver to coast across active traffic to the shoulder without engine pull. The engine revs freely in 'Drive' but the transmission fails to engage any gears. No dashboard warning lights, check engine lights, or diagnostic trouble codes are triggered during or after the failure. The failure resets temporarily only after cycling the ignition key off and on.The vehicle previously had Safety Recall SC250 (8-speed Electric Oil Pump) performed by an authorized dealer, but the software flash completely failed to prevent this catastrophic hydraulic/electronic failure mode or provide the federally mandated dashboard warning countdown.

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.

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.

COMPONENT: 2.5L T-GDI engine failed completely at 102,971 miles, requiring full replacement (~$8,000). Vehicle available for inspection at [XXX] Kia, [XXX] . SAFETY RISK: Engine lost power during normal operation. Sudden, uncontrolled loss of engine power creates a direct collision risk at highway speeds for the driver, passengers, and surrounding vehicles. CONFIRMED BY DEALER: Mark Kia performed a borescope inspection on April 10, 2026 confirming cylinder wall scoring, oil-fouled pistons, and worn honing patterns across multiple cylinders. Findings are consistent with Kia TSB ENG235 (January 2022), which documents a defective PCV check valve on 2021–2022 Sorento 2.5T engines allowing oil to contaminate combustion chambers. Vehicle was serviced exclusively at Mark Kia for all 17 visits since 2021. TSB ENG235 does not appear in any service record. PRIOR SYMPTOMS: No warning lamps or messages before failure. A certified 36-point inspection one week prior showed zero cautions. Spark plugs replaced at 74,534 miles (Jan 2025) were found fouled at ~102,000 miles, only 28,000 miles later — indicating silent, progressive oil contamination. The defect is undetectable by the driver until catastrophic failure. Kia America has not responded to two formal written dispute requests (Case #XXX, April–May 2026).
