Last week,coming home from Canada,I drove through some snow squalls near Buffalo. Needless to say,by the time I arrrived home,the car was filthy from the snow and salt. While driving around in town,at times,the sensors would seemingly beep for no reason. One time I put the car in reverse,and the sensor was beeping at almost a steady tone,and nothing was behind me.

The next day,I washed the car and it has not happened again. Has anyone experienced this?
