Exterior Lighting problem

Driving down the freeway at 60 mph, a message was displayed on the instrument panel "blind spot assist inoperative," and the turn indicators stopped working, both left and right. Had to exit the freeway, but was not able to indicate to other drivers that I was changing lanes, as turn indicators were not working. Came to parking lot, shut the engine off and started back up, then the turn indicators started working along with blind spot assist. However, the issue came back after driving a few more miles. This problem also happened on the surface roads traveling at 35 mph.
