Sportage slows down by itself!!

A warm hello to a new member. I would like to describe my big problem with my sportage as the first post. In humid and cold weather the ESP shuts down. Should not be so bad at first. However, it has happened at least 5 times that the vehicle with the front right wheel slows down out of the blue. (also at 130km/h on the highway!!!!!!) The vehicle was therefore already 5 times in the workshop, the control unit and e in sensor have been changed. But the error continues to occur. Today the car is back there again, but it showed again only the error of a defective plug-in connection. So the relevant connections are checked and cleaned. Is not the first time. Then I can pick up the car again. And now? Then I have again a super dangerous vehicle in front of the door, which I want to move only with a lukewarm stomach feeling. If I switch off the ESP manually, the error does not occur. D So I’m driving without this help. Is this a solution? A call to KIA’s service didn’t bring a solution. I’m thinking of selling the vehicle, but what should I say to a potential buyer? Or selling a two-year-old car as a hobby vehicle? That’s just ridiculous. Does anyone know this problem or something like that? I hope for informative answers. Greetings from Bavaria, Markus
