NHTSA Complaint #11440599 — 2021 KIA SORENTO

The vehicle has a dual clutch transmission which causes the vehicle to lunge forward at idle. The transmission also "slips" at times during hard acceleration and results in very slow acceleration when entering a highway on a ramp or making way across an intersection. The transmission also shifts extremely hard when coming to a stop and then lunges requiring additional braking. This presents a safety issue when crossing an intersection or coming to a sudden stop in stop and go traffic. The vehicle has 10,000 miles was inspected (and reproduced) at the Kia dealership where I purchased it, and the service department states that the transmission is working as designed, which I believe since there are numerous complaints about the same issue on line and Kia forums. The newest issue (about 2 months old) is that there is a whining noise that appears to be coming from the transmission during acceleration until the transmission shifts into another gear. There are no warning lamps - the issue has been occurring since purchased in May 2021. It appears that this issue is with the dual clutch 2.5 turbo models across the Kia line.
