Hi all, well here is my prob, I have a 2005 Optra5, it's been great til now, with no funky sounds at all. My cruise control is making a horrible sound going on and off, along with accelerating and decelerating, it's twice as bad if i have to use my break, sounds like something breaking. It has now been to 2 different GM dealerships, and to which they have fully replaced the whole cruise control system, but the sound is very much there, and i have contacted General Motors, and now told thats the way it sounds, so I pretty much have to deal with it. I find it hard to beleave no one can help get rid of the sound my car now makes, as I bought it brand new with no extra sounds.I hope someone can help me to figure this out, as I no longer want my car. tks Tanya
