on [redacted], 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. …
Incident #1: [redacted] 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. …
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 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. …
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. …
Transmission problem arised on/about 9/15/23 and 3,000 miles. There is a distinct shudder when shifting through lower gears, more recently, on/around 4,000 miles l, shudder is growing worse, and there is intermittent problems at highway speeds. This is very dangerous, and could cause an accident/injury at any time. I have been to my local Kia dealership 3 times now, who have flight recorded and concurred with me that its the transmission failing, but have been sent home every time with "we don't know exactly what it is, so keep driving it". These symptoms are very similar to the 2021 model years dct transmission recall problems. I know of others with this same problem, and Kia needs to be held liable asap.
Transmission Warning Indicator appears on Dashboard Cluster and vehicle bucks and stalls and won't shift properly. Dealership found Transmission was never filled properly and below specifications according to Kia Service and was verified the fluid level was extremely low and not filled to specification from factory. The dealership filled transmission to proper level and test drove vehicle. Issue seamed to be fixed. But now a month later same transmission is is happening with Transmission warning Indicator and vehicle bucking and not shifting properly causing erratic vehicle behavior and safety issues.
