I'm just wondering what it is. My father just bought a brand new Toyota Camry XLE. Recently when cold, while accelerating, it makes a fast clicking noise. He brought it down to the dealer and one of the girls, i'm assuming the operator, said alot of people have been complaining about the same thing and that there is nothing they can do and that it's just the pistons making noise until it warms up. I've been working on cars for years and it sounds like a load of bull to me. What do you guys think?
