Purchased a 2016 kia optima ex with the premium package with less than 30 odometer miles in april 2017 from a kia dealer (vin [xxx]). at 4200 miles the car stalled and lost all power while traveling on the highway during rush hour. screen flashed "engine control system - possible engine condition. " took vehicle to the kia dealer on 07/08/2017 who indicated the throttle position sensor needed adjusting and cleaning. they assured me all was good and they had resolved the issue. less than 24 hours later the car stalled again on the highway. had to have the vehicle towed to another kia dealer where it sits. this is a serious problem that needs to be addressed with kia as it poses a significant safety hazard to me and other drivers.
