VEHICLE SPEED CONTROL, POWER TRAIN
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

I was driving up a hill and my car stalled. Contacted Kia of Bowie for assistance had a diagnostic asked for a goodwill repair because of this being a safety issue with my car stalling while driving up a hill life threating situation and they have denied the goodwill repair the service tech is saying because I didnt get my car serviced there and they have no records I informed them that I have and had been taking care of the maintenance at the Kia dealership in Temple hills md. They are just overlooking the severity of the situation of a safety issue.

"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. The vehicle is entirely unsafe to drive,

ENGINE, POWER TRAIN
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 transmission slips, shifts harshly, hesitates during acceleration, loses power unexpectedly, and has become unsafe to drive. The vehicle is available for inspection upon request.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 move when needed to avoid a dangerous situation. 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. It is extremely frustrating and financially devastating 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 code P0741 appeared. Prior to that warning, the vehicle had already shown delayed shifting, slipping, hesitation, rough gear changes, and loss of power, which became progressively worse.This situation has caused significant emotional stress, anxiety, and financial hardship. I am requesting a full investigation and a fair resolution from kia.

POWER TRAIN, ENGINE
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.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
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.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
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).
