2023 Kia Sorento

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.

The contact owns a 2023 Kia Sorento. The contact stated that while accelerating from a stop or while driving and depressing the accelerator pedal, the vehicle jerked and lost automotive power. There was no warning light illuminated. The message “Transmission Fluid Low” was displayed. The local dealer was contacted; however, the vehicle was not diagnosed. The VIN was not under recall. The vehicle was not repaired. The contact referenced NHTSA Campaign Number: 22V760000 (Power Train); as a possible cause for the failure. The manufacturer was notified of the failure. The failure mileage was 208,600.

I have a 2023 Kia Sorento with approx 60k, purchased new from New Pot Richey Kia. Approx 7 days ago, while driving home from dropping my son at school, my transmission system error warning came on as well as my check engine light. My RPM'S would increased without corresponding acceleration, which meant my transmission, was slipping. I was also experiencing jerking during shifting. In addition to that, my car would hesitate before moving. And I would also experience a slight vibrations at low speeds. All of this would make me feel unsafe when driving my car.

Immediately after a dealership-performed warranty repair, the vehicle experienced a severe safety‑critical failure at highway speed. The vehicle began shaking violently, produced loud knocking and impact noises, and metal pieces fell from the underside. The failure occurred without warning and created an immediate loss of safe drivability. The dealership later documented that an engine mount (‘lower dog bone mount’) had not been torqued to specification, which allowed the engine to shift back and forth under load. This improper torque caused the violent shaking, metal impacts, and falling metal. The problem was confirmed by the dealership, but no corrective repair was performed. Only a single bolt was re‑torqued, and no inspection was done to determine the extent of damage, the source of the falling metal, or the cause of the knocking. The vehicle was returned in an unsafe condition and has not been driven since. The vehicle had to be towed directly from the highway due to the severity of the failure, and it was delivered straight to the dealership because it was unsafe to operate. The vehicle remains available for inspection.

I purchased a new 2023 Kia Sorento in February 2023 from Ken Garff Kia Avondale. Since shortly after purchase, the vehicle has experienced repeated electrical and mechanical failures that substantially impair safety. In July 2023, the vehicle began displaying flashing lights, dashboard error messages, and system malfunctions while driving, despite no collision or visible damage. The air conditioning system malfunctioned and blew hot air even when turned off. The dealership stated a front sensor was “damaged” and not warranty-covered, despite no visible damage, and verbally indicated that many other customers were experiencing similar issues. Repairs took nearly four months, during which Kia Corporate engineers were involved. The issue persisted despite repairs. In December 2024, the vehicle began displaying repeated transmission system error warnings, often within the first 5–10 minutes of driving, causing significant loss of speed and drivability. After multiple service visits, the vehicle required a full transmission replacement in July/August 2025 under warranty. Despite this repair, the same transmission errors returned in December 2025. More critically, the vehicle then experienced multiple sudden and complete electrical shutdowns without warning, including: Shutting off entirely while stopped at a red light, requiring a jump start All screens going black and the vehicle failing to restart Restarting only after being left parked for several minutes These events occurred without any battery or system warning indicators and created a serious safety risk, including risk of being stranded or disabled in traffic. The issues have been documented with photos, videos, repair records, and written communications. Due to the ongoing and dangerous nature of these failures, I am reporting this as a vehicle safety defect.

Incident #1: [XXX] The vehicle would not accelerate after coming to a stop at an intersection. The vehicle would not exceed 20 MPH with oncoming traffic from both the East and West as I was turning West from a North Bound Road. On coming traffic was traveling between 45 and 50 MPH. I was clearly nearly broadsided. The car displayed flashing lights on the dash as I was attempting to accelerate. Depressing the accelerator did not increase my speed. The car kept at a 20 MPH speed for the 1/2 mile I traveled to pull off the road in a safe location, causing traffic to be disrupted until I could pull off the highway I had the car towed to the Kia of Round Rock dealership November 17th. The car remained at Kia until December 3rd where they were unable to duplicate the problem. I requested the problem be referred to Kia in California. Kia of CA was totally unresponsive when the problem could not be duplicated. Incident #2 [XXX] Vehicle failed to respond to accelerate after stopping before attempting to enter a four lane highway. (No traffic was visible.) The car would not accelerate more than 20 MPR, the speed limit was 55 MPH. For the 1.5 mile trip home, I turned on my hazard lights, kept to the right and flagged traffic around me. The car never exceeded 20 MPH.

The contact owns a 2023 Kia Sorento. The contact stated that while the vehicle was parked, the gear shifter was shifted into drive, the accelerator pedal was depressed; however the vehicle failed to accelerate as intended. The contact stated that the vehicle failed to move forward. No warning lights were illuminated. The contact stated that the failure had occurred more than five times within a month. The failure occurred after a previous repair was performed by the dealer. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that previously, while the vehicle was parked on a hill, the gear shifter was shifted into reverse, and the vehicle rolled forward and crashed into a curb. The vehicle was taken to the dealer and was repaired. The contact was informed that the failures were not failures but instead the normal function of the vehicle. The contact submitted a Lemon Law claim and was advised to contact the NHTSA Hotline to report the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 21,700.

on [XXX], the check engine light came on solid. My car is just 2 years old, only has 22K miles, and is currently under warranty, as it is a leased vehicle. According to Auto Zone, it was a "speed sensor". On 7/25/25, I was able to get an appointment with Garvey Kia of Queensbury, NY and the fault code is the "input turbine shaft speed sensor B circuit range for performance". The service technician told me that it is not able to be accessed, as it is internal, and it is not serviceable. My safety and the safety of others were at risk because the car would go "limp" when accelerating, there was harsh and delayed shifting, erratic RPM readings, and no power when accelerating. This inability to accelerate causes problems in traffic and when trying to get through intersections or out of side streets when acceleration is imperative. Yes, the car has been inspected by the Kia dealership. This same exact thing happened on [XXX], in which Destination Kia of Albany had by car for over 4 weeks to replace the transmission. At that time, the car had under 10K miles and was not even a year old. At that time, they put a refurbished transmission into the car.

When I start driving, there’s a lot of hesitation like it’s going to stall and it also does this going up hills or mountains? I was on the interstate and there was a line of cars behind me and my car started to hesitate and almost stall, causing all cars behind me to break to not cause a domino effect accident I have reported this to the Kia dealer and knowing that there’s a lot of DCT problems that are posted all over the Internet they are saying there is no problem with the car upon doing research again there is a lot of DCT reporting of Kia’s not just my Sorrento please do some research on this and help me. We just bought this car. There is 13,000 miles on it. It should not be doing this and again I’m going to a different Kia to see if they say the same thing. Below you ask for a date that this happened there is too many dates to enter, but I will try to enter the very first one that we experienced.
