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.

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.

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

Our 2021 Kia SORENTO has been to Elmhurst kia service numerous times . The chief complaint is the Kia Sorrento keeps losing power while in drive reverse middle traffic even on the highway but yeah every time we take it in, they say either it’s the battery .you can’t use it in the Eco mode .turn off the shut off while in drive mode when at stops ! always a different excuse, but yet no recall and it’s not showing up on their computer, but yeah it’s happening and Kia does not want to take ownership. The vehicle has been left there for numerous weeks at a time leaving us without a vehicle no loaner . But because cannot duplicate issue release vehicle back with no repairs or maintenance. Kia prefer you taking the car getting into a car accident before they decide to do anything or even a lawsuit because not enough people having same issue with the 2021 kia SORENTO s model ! If you also have these issues please report them here so they can be forced to open a recall !!! Before someone gets seriously hurt my SORENTO has loss power on highway and in the middle of train tracks with my little ones in SORENTO and we drove the vehicle from day one original owners not a used SORENTO

On 3/26/2026, I was driving at 45mph when the vehicle started slowing down and the auto stop light on the dash was blinking yellow. Every time it blinked, the car slowed even more. I tried to speed up, but it slowed down more. This could have caused an accident. I pulled off on the side of the road and shut the car off. I waited a few minutes and started the car. It ran alright and the light did not blink. It has been alright so far. If it occurs again, I will call the dealer to have it checked out.

Component: Electrical System / Forward Collision-Avoidance Assist / Speedometer Incident Summary: ​I am reporting a catastrophic and uncorrected safety defect in my 2021 Kia Sorento (VIN: [XXX] ). ​Pre-Accident Attempts: Before April 2024, I repeatedly sought diagnosis for instrument cluster 'glitches.' The Kia dealer misdiagnosed this as a battery failure, charging me out-of-pocket for a replacement that did not resolve the issue. ​Collision (April 22, 2024): While driving, the instrument cluster suffered a total system crash into 'Factory Mode,' losing all telemetry. Simultaneously, the vehicle's Forward Collision-Avoidance Assist (FCA) failed to engage. Despite the vehicle being equipped with automatic emergency braking designed to detect and mitigate collisions, the system provided no warning and no autonomous braking prior to striking a deer. ​Post-Accident Failures: Following the crash, Geico Insurance funded a wiring harness replacement at a Kia facility (backed by a Geico Lifetime Warranty). However, the glitches and 'Factory Mode' errors have returned, proving the vehicle's core safety systems remain compromised. ​Safety Risk: This vehicle is non-compliant with FMVSS 101 and 127. The failure of both the speedometer and the autonomous emergency braking creates an extreme risk of further injury or death. Kia Corporate has failed to address this documented accident history.

My vehicle completely shut off while I was driving with my children in the car. The dealership replaced the battery but never identified the root cause. Since then my car has been experiencing RPM surging while in Park — the engine revs up and down repeatedly on its own. The vehicle also feels sluggish and does not want to accelerate properly while driving. Additionally since taking ownership of the vehicle my window has squealed every time it rains and I roll down the window. The dealership has replaced the seals, lubricated and cleaned the window multiple times and the problem persists. The defective window seal also caused a gash in my window tint requiring replacement. I have taken my car to my Kia dealership multiple times and they have been unable to fully resolve these issues. My car is currently at the dealership right now and they still cannot find the problem. I contacted Kia Corporate on March 20, 2026 and opened a formal case. These defects have put my children in danger and I am requesting a formal federal investigation.

The issue appears to involve the electric oil pump and related components. My 2021 Kia Sorento had a recall for the electric oil pump that was marked “completed” in January 2023; however, the dealership only performed a software update and did not replace any mechanical components because no fault code was present at that time. Beginning around October 2025, the vehicle started experiencing drivability issues including hesitation and bogging down when accelerating from a stop. A dealership representative later stated the electric oil pump and housing likely need replacement and that the transmission may also be affected. The vehicle is available for inspection upon request. This issue creates a safety risk because the vehicle frequently hesitates or bogs down when attempting to accelerate, especially when pulling into highway traffic. When pressing the accelerator, the vehicle sometimes struggles to engage and move forward, which increases the risk of a collision. I brought the vehicle to Kia of RBC and spoke with Service Advisor Justin Hawkins. At the time of inspection, the check engine light had turned off and I was told they could not diagnose or repair the issue unless the warning light was active. I was instructed to continue driving the vehicle until the light returns. During a later conversation, dealership staff indicated the electric oil pump and housing likely need replacement and that the transmission may also require replacement, but they could not confirm this without the warning light being present.

The car has completely shutdown on 3 separate occasions. It wouldn't start and all the electrical did not work. It started the next day. All this in a span of 5 out of the 8 months we purchased it. The last time, we found the fuse box was burnt when the tow truck showed up to take it to the dealership. The dealership is trying to blame us because we changed the battery after the second time and not honoring the warranty. They are trying to charge us $18,000. The car had already shut down two times before we even changed the battery. We contacted Kia corporate and nothing has been done, but just phone call saying they will call us back after they talk to the dealership. I got so scared for my wife because she was the one driving the car. This is such a dangerous problem with the fuse box. I researched car problems with Kia Sorentos and sure enough other Sorentos have been recalled, but not ours.

The drive mode selector in my Kia Sorento was found to be defective. The selector forces the vehicle into "Eco" mode on startup regardless of the previously selected mode. This creates unexpected throttle response at startup given the manual states leaving the vehicle in other modes (such as "Smart" or "Comfort") will be retained on key-cycle. The specific incident in question produced unexpected throttle response while backing into a highly-trafficked road and resulted in unexpected proximity to oncoming traffic. The selection module has a further failure state: the backlight lamp showing selected drive mode has gone out preventing ready identification of current drive mode.
