The SUV had a whistling noise then started leaking transmission fluid. I brought it in and the master tech said the whole transmission needed to be replaced. This is a NEW vehicle which only 5000 miles on it.

Power train operation is erratic and unpredictable. I have have experienced the same problems of other reports (loss of power when turning, jerking/rough shifts, cruise control issues) with the addition of this: when stopping the vehicle in a smooth controlled fashion, it suddenly has a boost of acceleration at 1-2 mph which requires extra brake pedal pressure to keep from impacting the car ahead.

Transmission failed at 3200 miles leaving my family stranded. Car was completely disabled abruptly. Luckily I was able to find people to push my car to a safe location until my tow arrived. This was very scary given the fact I had my three children inside.

The transmission is failing after only 6000 miles. The vehicle suddenly and without warning will stop functioning, this happens while driving. The vehicle comes out of drive gear while still running and leaves driver with no ability to move out of traffic. This has happened numerous times over the last few weeks. After researching online it became evident that this is a common problem with the 2021 Kia Sorento. Many consumers complaining of the same thing. My wife was almost rear ended Saturday when the vehicle jumped out of gear and she was unable to get it out of traffic. These vehicles pose a very high risk and probability of causing accidents.

I am having trouble with traction control on my 2021 SX Xline... when turning it comes on suddenly resulting in power loss and no ability to accelerate. This has happened four times since purchasing the vehicle. I nearly got hit when it happened twice last night trying to get home. It is dry here - no water or rain. The vehicle was in smart mode, has awd and the traction control lights flickered on and off on and off right before the problem happens.

On Wednesday June 2, 2021 around 12:15pm I was leaving a teacher summer workshop and I started the car as usual, no issues, and proceeded to leave the parking lot to make a right turn onto the street. I was about a mile away from home. As I proceeded to hit the gas the car moved forward into the street then failed to shift into the next gear, which left me stranded with traffic quickly coming up behind me. I turned the wheel really hard to get as close to the curb as possible. I proceeded to press the gas pedal all the way to the floor and nothing happened except high rpms around 3-4k. I looked at the dash to see if there were any warning lights, at the same time I am pressing the gas pedal trying to get the car to move forward. It suddenly moved forward so I merged over to the left lane, with traffic coming up behind me, and it happened again. It failed to shift into the next gear and seemed to be stuck. I am moving forward about 1-2 mph. I stop in traffic and within 15 seconds it caught second gear and moved forward and I was able to make it to the middle lane. The Sorento started to act normal, shifting gears and moving forward, so I proceeded towards the light to make a left-hand turn. I waited until all the oncoming traffic passed by to make my left-hand turn, then I hit the accelerator and it lurched forward and wouldn-€™t shift into the next gear, it just continued to rev to 4k. I-€™m coasting along at about 1-2mph trying to get through the intersection so I don-€™t get hit by another car. I move the shifter into a different gear to see if it would catch and it didn-€™t. I continue pressing the gas pedal and it all of a sudden lurched forward and started acting like normal. I was about a half mile from home at this point. The car acted like normal and I was watching the dash to see if any warning lights were illuminated, no lights every appeared on the dash. Dealer can't replicate issue.
