    Engine ticking noise

    As a first time Cadillac and American car owner my ATS with 2300 miles when I am out of the car I notice a ticking sound from the engine (3.6 l) compartment. Dealers says this is normal. Any confirmation of that

    the 3.6 sounds like a lifter needs adjusting, but it is the extreme high pressure direct injectors opening and closing, every DI engine I've come across has this to some extent.
