2006 Cadillac Dts with 23,000 miles on it and at a stand still and when coming up to a stop and making a turn there is a definite click or knock in the front wheels or steering column that you can actually feel. Even when sitting still you just turn the wheel a little bit back and forth and there is knock that can be felt. Have report to local Cadillac dealer and told nothing can be done and to live with it. Tried another dealer ship 45 miles away and they heard the noise also and cannot figure where it comes from then tried 3 other cars in lot of same vintage and the ones with more miles on them had the same noise. I would expect that from a less expensive car but not a Cadillac. Also have a tire noise that Cadillac and continental tire said is normal. But this is embarrassing when you pull up to stop or driving at low speeds you can hear noise like a squeak or rubbing noise like the brake pads are rubbing. Told this is could be the design of the tires, but have no proof and Cadillac field rep would not give me the pleasure of talking to him, I had to discuss through a 3rd party that did not understand the issues and I was by him that the rep do not talk to customers they only give their opinion to the 3rd party and they in turn pass info on to customer. Not sure what a customer field rep does if he does not talk to a customer, they should change their title then. Am now fearful that with the tire issues and the steering clucking that this could lead to parts failure or accident leading to a death etc.
