One problem related to tail light switch has been reported for the 2015 Kia Motor Sorento. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2015 Kia Motor Sorento based on all problems reported for the 2015 Sorento.
The passenger tail light went dim (while braking) and then stopped working (only when braking). Replacing the bulb does not fix the problem. Kia dealer says they will have to put on a machine and they think its an internal computer issue. I have noticed many other Sorento's with the exact same tail light out when braking.
