Rearview System Braking problems of the 2019 Kia Motor Sorento

I bought this car back in January 2024. I had it for about a week and the check engine light came on. When I had it read it was a torque converter clutch solenoid. I took it to kia they said it needed reprogrammed, it was fine. Then a few months go by and I take it back in and they told me I needed to spend $5,000 for a new transmission at less than 100,000 miles. When doing research a lot of others have had this issue as well. They said there maybe a recall eventually but until then I had to pay for it. I paid for it there is still no recall. Also the rear cross traffic goes off as a car is behind you, there’s not really a warning before the car is behind you.
