If you activate your turn signal and the blind spot monitor for the same side triggers, you get a tone that is similar (but not exactly the same) and the lane departure warning. I notice this mainly in the outside of multiple turning lanes with other car(s) in the inner lanes.

Thanks Joe. I could be mistaken but I thought I've had this sound happen even when I'm driving in a straight line. I could be off though, my memory isn't perfect these days. I will definitely keep that in mind the next time I hear the noise and hopefully that's all it is. I do recall it going off yesterday in a multiple turn lane going left, with me on the outside with left signal. So that makes sense.

Have you tried looking at your dash at the temp display and see if it is flashing when the beeping occurs? I know several Kia owners didn't know that when the temp falls below (I think) 39F, there is a beep and the temp flashes, to warn you of possible icy conditions.

Thanks for the tip! Not the case for this situation (warm California) but useful info for whenever I'm somewhere with cold weather. I'm hoping this is just the blind spot monitoring system. I've since turned it off altogether and if I no longer hear the beeping then I know what it is. Fingers crossed that's all it is.
