2014 Hyundai Santa Fe Sport blind spot detector

Blind spot detector suddenly stopped working. Light will not go on when button is pressed.

Then take it to the dealership to get fixed, or ignore it and drive carefully

Inspect the rear bumper cover on both sides of the vehicle behind the rear tires for signs of impact. Any type of impact can knock a Blind Spot Monitor module out of position and disable the system.

Thanks everybody! I think dirt or something was blocking the sensors. We had a very hard rain last night - working fine this morning.
