The overall trip distance was over 700 miles. The ticking noise came back once in a morning than disappeared after few miles. It was not very loud. I think I'd want car checked at the dealer but how I am going to let them hear it? When I have the noise it always disappering after a couple miles and usually does not come back ...
I've got a tape recorder in my car so when it does make ticking noise I'll record it -- not even sure if it is going to be helpful or not. Or other option is to continue driving and see if it will beome worse or not. Well, anyway that is kind of all the options I can think of right now. Don't know what else can I do.
