Gas Recirculation Valve (egr Valve) problems of the 2014 Kia Motor Optima

Driving today on interstate 20 in south carolina at 70 mph and car just suddenly cut off. Had to wait 31/2 hours for tow through kia roadside assistance in 95 degree weather. Car will not start, had battery checked but car won't do anything, all dash lights, headlights, radio all will come on but the engine won't turn over to crank.

I took my vehicle to have the 1803 software update done less than 2 weeks ago. I was driving back from vacation going approx. 80 mph the car cut off and several dashboard lights came on. I was in the far left lane, my car was decelerating, I needed to move across two lanes of traffic to get to the side of the road! it is an absolute miracle I was not hit or something catastrophic happened. I have called the dealership where I had the software update done. He was very transparent and explained the 1803 software update to me. Ideally the concept is to set the computer so the engine will shut down to avoid piston or other parts to go through the engine. The software update raises the sensitivity level to detect an issue with the engine, not necessarily to correct or stop it from happening but was told the update is done so it will not cause a catastrophic situation to the engine! seriously?!! it did cause a catastrophic situation, I was lucky to not have been killed! my car sits 2 hours away, 2 1/2 days later and no answers. I called twice, I have been told I should have some answers today around 2 pm. I asked how I will get my car, I was told kia does have a "reunite" program but seeing as it is w/in the same state it may not be approved to get my car delivered! kia is joking, right? my car (obviously) is having major issues and researching issues and reports online appear to point to the engine. Is there a class action law suit going on right now? I am going to look into this and pretty sure I won't be purchasing another kia ever and will be telling numerous people and social media outlets about this horrific story that could have ended tragically for me. P. S. When I contacted kia for a tow I was told it would be 90 minutes, I sat in 98 degree heat on side of road for an hour and a half! thanks kia! improve your cars and all facets of customer service.

While driving with my family of 4 on the freeway in a desolate area of santa clarita on 9/24/16 at 3:15pm my vehicle shut off without any warning. We were going 65 mph, all lights on the dash flashed and the car shut off. We were in the 2nd lane and had to use the momentum of speed to make it to the shoulder, we were almost hit. Once we made it to the shoulder of this busy freeway, we were unable to start the car, put windows up or down, open the trunk etc. The car was completely dead. We sat waiting for aaa and hoping not to get hit. It was 85 degrees out and my 74 year old mother and disabled sister sat in the car for 30 mins until the tow truck arrived. If we weren't so lucky or if we were in the righter lanes of traffic 4 lives could have been lost that day. I am very anxious and nervous to drive the vehicle again however; I have no choice it is our families primary vehicle. The service rep at the dealership told be prematurely that it is the motor however; the diagnosis is not finalized. I fear for the safely of my family and friends in the car now, and really do not want to drive it again. It gives me major anxiety especially since I drive from CA to az 4 times a year and now fear this happening in the middle of the desert. I don't understand how a car 19 month old with 48k miles can have this type of issue. Actually I don't know how any car any age and miles can have the issue of just shutting off without warning, it is a major safety concern.
