Kia Sorento harsh shifting problems

Filed Nov 2, 2026 · Transmission · MN

My 2021 Kia Sorento (VIN [XXX]) is at Luther Kia. The dealership documented DTC P1C2D03 as stored. Kia's SC250 recall procedure states that if P1C2D03 is not stored, the dealer updates the TCU software only; if P1C2D03 is stored, the transmission is to be replaced and updated TCU software applied. Despite the stored code, Luther Kia did not replace the transmission. They updated the ECU, rescanned, performed an air-bleed procedure and transmission relearning, test-drove the vehicle, and marked the repair complete. I am concerned this does not comply with the remedy specified for stored P1C2D03 and leaves the vehicle susceptible to the loss-of-motive-power condition addressed by the federal safety agency Recall 22V760000/SC250. After receiving no update since late morning XXX, I called near closing XXXand was told their only Authorized Kia Warranty Service Technician was out sick. That evening I emailed the GM documenting the SC250 concern and requested resolution by Monday morning, including release of my vehicle while the transmission was ordered or a loaner/rental if unsafe to release. As of Monday afternoon, I have received no response. I also opened a case with Kia Corporate on XXX. The dealership sent me a $528.28 invoice via text and is retaining my vehicle pending payment of the entire invoice. This includes $178.98 I understand to be recall-related diagnosis/labor, although SC250 states there is no charge to the owner for this repair, plus $311.36 for A/C diagnosis and a $36.94 miscellaneous fee. I was instructed to drive approximately 1,000 more miles for the A/C issue. The odometer is approximately 99,2XX miles, which would exceed 100,000 miles and may affect CPO warranty coverage. A rear clunking concern potentially related to Kia TSB TRA105 was not resolved. I request the federal safety agency investigate whether SC250 was properly completed and whether this vehicle is safe to operate without the transmission replacement specified for stored P1C2D03.

Hard shifting and kia said I need a new transmission, 99,500 miles

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/the federal safety agency 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 the federal safety agency review whether my vehicle's condition may be related to the existing safety defect and whether additional vehicles should be investigated.

The transmission failed for the fourth time. The transmission (Power Train) is the component that failed and is available for inspection at the dealership. The vehicle became unsafe and unreliable to drive due to the repeated transmission failures, creating a risk of sudden loss of power or control. The problem has been confirmed by the dealer on multiple occasions, most recently on August 24, 2026. The vehicle has also been inspected by Kia America as part of an open case (Case #25964896). History: The 1st transmission failure was covered under the original factory warranty. The 2nd failure occurred after the 12,000-mile transmission replacement warranty had expired, requiring an out-of-pocket repair of $5,500. The 3rd failure occurred within 12,000 miles of that replacement and was covered by Kia. On August 24, 2026, the dealer confirmed the transmission had failed again — a 4th failure of the same component. Warning symptoms typically appeared as loss of power, hesitation, or rough shifting prior to each failure.

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 involved is a 2019 Kia Sorento with approximately 111,000 miles. Over the course of ownership, the vehicle has experienced numerous unresolved mechanical and safety-related issues, including ongoing fuel leak concerns, excessive oil consumption/loss of oil, rough shifting, shift solenoid problems, rattling noises, shaking/vibration while driving, and repeated drivability issues. The primary safety concern at this time is a suspected fuel leak that multiple independent mechanics have identified. I have been told by at least three separate mechanics that the vehicle appears to have a fuel leak. During my most recent oil change at Valvoline, the technician expressed concern about the safety of driving the vehicle in this condition and warned me that driving a vehicle with a fuel leak could be dangerous. I previously brought the vehicle to Kia dealerships multiple times while the extended warranty was active and specifically requested inspection for the suspected fuel leak. On at least three separate visits, I was informed by the dealership that they could not find or confirm a leak. Because the issue was never resolved or properly diagnosed while under warranty, I am now out of warranty coverage and facing potentially dangerous and costly repairs. This issue has placed my safety and the safety of others at risk due to fear of possible fire hazards, stalling, or sudden vehicle failure while driving. Because of these concerns, I have significantly reduced driving the vehicle and currently do not feel safe operating it regularly. This has created substantial hardship because this is my only vehicle for work and daily life. Additional unresolved issues with the vehicle include: - Persistent rough shifting and shifting hesitation - Shift solenoid issues - Ongoing excessive oil consumption/loss of oil with no confirmed source - Constant rattling noises - Excessive vibration/shaking while driving - AC system failure around 60,000 miles - Electrical seat failur

The vehicle’s transmission failed. While driving on the highway, the transmission began slipping and then would not allow the vehicle to accelerate beyond approximately 10 mph. The vehicle also lost the ability to reverse. My family’s safety was put at significant risk. The incident occurred on a highway with a speed limit of 70 mph and low visibility. Due to the sudden loss of acceleration, our vehicle was unable to keep up with traffic, creating a dangerous situation with a high risk of being struck by other vehicles. The dealer reproduced and confirmed the issue. They documented very hard shifting, lack of reverse, and stated the transmission fluid smelled burnt. No diagnostic codes were present. The dealer advised replacement of the transmission. No warning lights or messages appeared on the dashboard prior to the failure.
