Transmission Not Go Into Gear problems of the 2011 Kia Motor Forte

I bought a 2011 kia Forte and was having issues where the car seemed like it was dying after initial starting of the vehicle and sometimes wouldn't go into gear. After driving it seems to correct itself and I brought it into kia. They put it under a specific claim number incase the warranty went out it is still covered. A few months later the car started to not go into gear even more and issue of dying seems more prevalent. Now kia is trying to say it could be a number of things which are not covered because the warranty is up from factory, and the extended warranty they claim doesn't cover powertrain which last time I checked powertrain includes shifter/gear shifter. They are now refusing to fix the issue because they have no clue what the actual problem is but have seen the issue first hand. This car has less than 70,000 miles and 70% of the time you cant put it into gear. This is a major safety concern since it could pop into any gear it wanted to and if I am doing 70 mph and it decides to go into park it wont be a fun ride.

While driving and attempting to gain speed to enter the interstate highway in san antonio texas the transmission would not change gears and had to pull over. I then had the vehicle towed to a kia dealership 10 miles away. I am awaiting a call from them regarding repairs.
