My 2005 Cadillac STS is a nice car but the front end rattles excessively at speeds of 35 MPH or under. To date, Cadillac has been unable to fix the problem. So far, they have replaced a control arm but that still has not fixed the problem. If I had it to do over again I would have purchased the Infinit M35 or BMW 530i. This will be the last time I buy an American luxury car!
Suspension leaves something to be desired. Fix the rattles and noises.
