NHTSA Complaint #11438703 — 2020 KIA SOUL

I was driving down the interstate at 70 mph. Noticed the car felt like it was accelerating and then decelerating like I was fighting against a strong wind. Looked at the tachometer and saw it fluctuating between 2000rpm and 3000 rpm. Suddenly it redlined to 7000 rpm and I had very little power to the wheels. It would drop back to 3000 but if I tried to accelerate it would redline. I was in heavy interstate traffic. I barely made it to an exit and into a parking lot. By the time I got off the highway it would go no faster than 5mph. I tried restarting the car to find I couldn't go forward or in reverse and the engine would go to 7000rpm. I have about 24k miles on the odometer. Bought brand new from the dealership. Easily could've been rear-ended or crashed in the heavy traffic with no power to the wheels.
