The car will not start after a short trip to market, shop for <hour, come out to start car turn ignition, car will not turn over, all dashboard lights come on, I jiggle shift gear in park and then turn key in ignition again and it might start after a few or several attempts. This happens on consecutive days and then may skip several days before another occurrence. On three visits to the dealership and problem can't be duplicated although it happened in oct 2015, (41,575 mi) July 2016 two times, August 21,23, 26, 27,28, sept 11, 12, 20, most times it was stationary except for the July 26, 2016 when I was driving it lost momentum and I pulled off the road stopped turned it off and then it would not restart. Dealership still could not duplicate the problem. Has anyone else reported this problem with kia Optima 2012? I'm afraid to even drive the car because I don't know when it will happen. I won't dare take the car on a trip I have asked kia customer service to authorize a loaner car for up to 30 days so they can take the car and check everyday until the problem is duplicated. Kia will not provide a loaner car so that I have transportation and they can keep the car to determine the problem.
