NHTSA Complaint #11584615 — 2018 KIA OPTIMA

It started with the car using oil but the mechanic could not determine where the oil was going. It quickly lead to the Cadillac converter going out with a host of other things that cost me over $2900 to fix. Which only lasted a few weeks and the last incident occurred when I was on my way home and it would not pick up speed at all and would stall. The first time it happened I was on the free way and it lost speed almost causing a semi to run into the back of me. The second time I was at a red light and when I tried to accelerate in speed and it stalled and then began to jerk before it would pick up speed. Each time the occurrence happened it placed my life as well as my families life in danger as it was sudden with no engine light or any other lights coming on. The last time it happened it left me stranded with a child, over 2 hours from home and in the middle of the night on isolated highway. Every time I would call KIA they would give me the run around on the issue and say it was due to my negligence but I beg to differ as I feel as if it is an engine error on the manufacturing. Please help. Currently the car is sitting in my yard and I can not afford to keep paying for repairs due to a faulty engine that they refuse to fix.
