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.
