NHTSA Complaint #11454440 — 2021 KIA SORENTO

I've had a concern for last several months with my transmission not shifting from 1st to 2nd gear. A new car with 100,000 mile warranty shouldn't be having transmission issues, so just started paying closer attention to ensure it wasn't my imagination. Gears not shifting became worse & more noticeable. On 2-21-2022 (on way to work), the transmission wouldn't shift from 1st to 2nd and then 2nd to 3rd gears. The RPMs went to 4,000 and 5,000 respectively. No lights are showing. I noticed a beep (like a seatbelt not engaged) that sounds 3 times prior to the transmission issues. Nothing in seats to activate a "seatbelt not buckled" sound. I pulled over, shut car off, sat for a few minutes & restarted the car. Same issue. The car was not moved again until 5:15 p.m. to head home from work (35 miles one-way commute). I pulled out onto the highway and transmission again rev'd to 5,000 RPMs. Pulled over and shut car off again. Car in park, restarted the car, and the car lunged as if going into gear, but I was in park. On 2-22-2022, same issue as the day before. Still no lights coming on. Called dealership & had Kia roadside assistance tow the car. Dealership kept for 3 days and could not duplicate the error. On 2/27/22, drove to church & had same issues. Returned home, put car in park in driveway (still running), the car shuts off and restarts on it's own. Monday, 2/28/22, does not appear to have any gear shift changes on the way to work until 5 miles from work when traveling 45mph and the car stalls almost to a dead stop in traffic; engine light comes on. Sent pic of engine light & text service advisor. Car towed by Kia roadside assistance to dealership. Now I'm without a vehicle because Kia won't provide a loaner car. I can rent a car and take it up with Kia Customer Cares in hopes of getting reimbursed - which is not likely to happen. 25,000 miles on car. Very Unsafe - does someone have to die to get issue resolved/recalled?
