| Description of the problem | On 4 separate occasions while traveling on highways at highway speed in ev mode, getting a warning "check hybrid system turn off engine" along with a check engine light; these are the occurrence dates 12/01/2017, 12/11/2017, 12/23/2017, 01/06/2018. Each time has been accompanied by a complete loss of gasoline engine availability resulting in a significant and unsafe drop in vehicle speed due to the car only being able to continue running on battery power. After pulling over i have been able shutdown the car and restart. Upon restart, the gasoline engine does come back on. Also note the "check engine" light has turned back off by the time i have taken the car back to the dealership. The car has been to the dealership twice now and supposedly repaired both times under warranty. The first repair attempt on 12/12/2017; the dealer was instructed by hyundai to try tsb 16-01-020-1. The second repair attempt on 12/27/2017; there had been a p261f and p0a0f fault code and the dealer was instructed by hyundai to replace all four spark plug coils. These attempts have not fixed the underlying problem as represented by the latest occurrence on 01/06/2018. This car is less than two years old and had only 36000 miles on it when this started happening. |
