One problem related to engine rattling and whining sounds has been reported for the 1999 Cadillac SLS. The most recently reported issues are listed below.
When I first purchased the car it had a cracked head and many other minor problems. I repeatedly brought it back to the dealership and they told me that there was nothing wrong with the car. I am still experiencing a "check gas cap" warning and I hear a clicking noise coming from the rear right side everytime I apply the brakes. Also I hear a rattling noise everytime I hit any size of bump.
