Replying to: dotty3 (Dec 24, 2007 5:21 am) I had the same problem. I recorded the noise so the dealer could hear it. He said it was a piece of plastic that sits between the engine and transmission. Somehow the winter's cold affects that piece and causes it to get hit by some kind of fan or fly wheel. He took that piece of plastic out and cut a notch in it.

Replying to: csesa (Jul 26, 2006 3:41 pm) MY GOD..My 2005 Buick LaCrosse does the EXACT same thing. On occasion, I'll turn the key and NOTHING, not even a sound. Wait a minute and VOILA. it works. My problem not is I have two lights on and I am not sure why. My security light is on. It looks like the front view of a vehicle with a lock image on it Second light that is on is my service vehicle soon light. Not the check engine light. My 2005 only has 35K miles on it.
