2021 KIA FORTE Power Train Problems

Transmission, yes it’s available. I was driving on the highway and the vehicle began jerking and revving, slowing down and then speeding up. It is at a service center now. Now lamps

The transmission went out while driving, entering the highway. It was intermittently missing a gear or slipping in about 2nd or 3rd gear. I first noticed it going about 40 mph and trying to accelerate to highway speeds. It was during a winter storm and other vehicles behind me had to brake unexpectedly. I wasn't sure if I felt for sure, so I continued to drive through many inclines and declines. The inclines became more difficult and the inability to maintain consistent speeds. I drove gently to the nearest Kia dealership which was in Salt Lake City about 60 miles away, where they informed me that I needed a new transmission. The car had about 75,000 miles on it and I bought it as a certified Pre-owned Kia with about 4,000 miles on it. The dealership plugged in the diagnostic code reader. But there were no codes detected. The service...

The issue I’m having was confirmed by the dealership so when I drive on the highway, there’s a specific patch of highway that zigzags the car will follow that zigzag after getting off of the highway onto regular road. The car computer system will start a down shift erratically and feel like the car is pulling backwards. Also there is a lack of acceleration and it feels like the transmission is slipping, but I have confirmed with the dealership that the transmission was not slipping that the computer was shifting erratically. They would reset the computer and the car would would begin driving in a more normal state shifting correctly. I get on the highway again. The car once again will start shifting erratic. When you let go of the gas, the car downshift so many times that the car almost comes to a complete stop without hitting the brakes....

It seems the car may have a defect in the transmission(Dual Clutch). The car makes at times an abrupt stop, for like a second or two, after I press on the gas. When I'm driving, especially at low speeds I can hear the transmission's parts make a grinding sounds, loud clicks. When I'm breaking, it's not smooth at all; I feel the car pulling a bit when switching to lower gears during the breaking process. When I have the car on and not moving (i.e parked), I can hear sounds emanating from the bottom of the car, like parts grinding against other parts. I have not seen any indicator light turn on from the vehicle, to this day. I have taken it to the dealership before, more than once, but they haven't found any issues with it. Still I feel they have not done a full inspection of the car,...

Vehicle has issues where transmission actuator will stop functioning causing sudden loss of acceleration. Was doing 70 MPH in expressway and vehicle stopped accelerating. Issue has occurred two times, both times being serviced by Dealership, after receiving the vehicle back, issue still persists, vehicle lost acceleration suddenly when turning into a intersection.

Car stalled and shut off while in drive leading it to be towed.
