    Most back up warning system issues I have experienced were caused by (unknown or known) impact of the rear bumper, causing sensor damage. A diagnostic test should help narrow down the issue to a specific system or component.

    My wife said no impact of the window when this happened. Does the warning system work like a sonar on a ship? Ed 4-11-2011

    Doesn't mean she or you hit the window. Could be a problem pre-existing. Remember that people park really rudely sometimes - and could bump into your bumper, causing sensor damage.
