Headlights Turn Off While Driving problems of the 2013 Kia Motor Optima Hybrid

I have a 2013 kia Optima Hybrid with faulty headlights that have completely gone out/failed over 10 times starting 3 mos after purchasing the car. After 1/2 years and 4 fixes, including completely replacing the headlight package, I filed the lemon law paperwork (I purchased in April 2013. ) in Nov of 2014. I was told they get a final fix. They replaced the entire headlight system again. Then, in Dec 2015, my headlights went out again & had to be completely replaced again. Kia corporate has been rude to me and denied any assistance even though they had completed the final fix a year before. I have phone videos (with witnesses) from years ago, 11/18/14, 1/25/16, 3/18/17, 3/27/17, 4/8/17 and 12/10/17. Most of the times I have been out and have had to drive home in dangerous conditions. I love my car but hate the dangerous issues. Kia has made me feel as though I'm not important, my safety is a non-issue and that they fix it every time, but it is not truly fixed if I have had 6 major repairs over 4 years. I've been at the point of a nervous breakdown over the stress and fear for my safety and of letting kia bully & convince me I do not qualify to get my car replaced. I am putting my safety first not to mention the emotional stress, interference with my work, putting family & friend's safety at risk. Never knowing if and when it will happen again & have not driven it many times because of this issue. I've been told too many times this is the last fix! I don't like conflict and have put my faith in kia too many times and put my faith in them over myself. I'm done being the nice person. I have had meltdowns over this, arguments with my significant other over this, interference with my work, been stranded out of town because of this! kia told me today they will not replace my car at this time. I cannot go on like this any longer. I need your help. Sincerely, kelley sullivan.
