Sounds familiar. I'm pretty sure there was a thread not long ago by an owner who would get violent shudders when he backed out of his driveway and the CEL would come on. Couldn't reproduce the problem for the dealer so they didn't believe him at first.

I looked for the thread but I couldn't spot it. Maybe someone else will remember. I believe the resolution was that the dealer eventually figured it out.
