2021 Kia Sorento: jerking or lurching

Filed Oct 26, 2026 · Transmission · FL

When driving between 10 to 50 mph with foot on gas pedal my car won’t jerk sputter and lose complete loss of power while making a turn. I have to release my gas pedal and push back down and it takes a solid couple seconds to get any power back. I’ve been almost hit a couple times in the last two weeks because as I’m turning my car just loses all power.

I noticed my car having a delayed engagement whenever i put it in reverse. I had to wait a couple of seconds before it would go in reverse. As i was leaving my job there is a hill and i noticed jerking when trying to accelerate up. As i made if past the hill i stop at a light,upon takeoff i noticed my car wouldn't accelerate but the RPM gauge spiked.i turned it off and then back on and it did the same only this time the check engine light came on. The issues i am having with my car fits the description of what the recall is for and i can't believe my car isnt part of the recall! The same make,model,year and engine(turbo). The car isn't even drivable and i will have to have it towed to a dealership and it could be days before they can look at it.

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 (the federal safety agency 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.

I am writing to formally file a complaint regarding my 2021 Kia Sorento and the repeated lack of resolution from the dealership where the vehicle was purchased and serviced. I have taken my vehicle to the dealership multiple times to address ongoing and serious safety concerns. Despite having active warranties on the transmission and powertrain, I have continually been told that there is nothing they can do, and my concerns have not been properly addressed. The vehicle is experiencing persistent issues, including: The transmission jerking and jarring when shifting gears The dashboard and center display screen intermittently go completely black while driving These issues do not occur constantly, but they happen frequently enough to pose a significant safety risk. I regularly have my grandchildren in the vehicle, and their safety, as well as my own, is my highest priority. Each time I have contacted the dealership to report these problems, I have been met with excuses and resistance to even scheduling an appointment. Due to the lack of cooperation, I felt I had no choice but to drop off my vehicle on April 13, 2026, without an appointment in order to have it addressed. I am extremely disappointed in the level of service and treatment I have received. As a loyal customer—this being my third vehicle purchased from the same dealership—I have never experienced this type of disregard. I also feel that I have not been treated fairly and, at times, have been dismissed in a way that is concerning and unacceptable. I am requesting the following: A full and thorough diagnostic of my vehicle, specifically addressing the transmission and electrical issues Proper repair under warranty Clear communication regarding findings and next steps Immediate attention to these safety concerns I purchased this vehicle with the expectation of reliability and safety. At this time, I do not feel safe driving it, and I am requesting that Kia take this matter seriously
