Mine (right front) has come on (or stayed on) three or four times.

Pushing the PDC button on the lower console shuts it down & then all is fine.

In my case it has not been worth a trip to the service center.

Mine was a November 2007 build so it looks to be outside the dates in the posted doc.

Let us know what you discover.
