NHTSA Complaint #11551951 — 2021 KIA SOUL

car is doing jerk moves and it stopped working when i was driving around 30 mph in a hospital area. Ive been told that car is burning oil since day one. The only ppl changing the oil is the kia dealer and i've been told to change the oil to get it fixed but i need to change the oil every 4k miles and car is brand new from 2021... I already been in dealer reporting that car needs engine replacement and they always say that car only need oil change. However, this month a person from that dealer told me that he changed many kia same model and asked me to call kia to get the engine replace, because the car is gonna get me kill. He doesnt want me to say his name but i will sue Kia if something happens to me.
