I had this problem. Creaking sound on tight turns such as parking lot spiral. You need to ask the dealer for the "special" differential fluid. Search the forum/online and you will find the service bulletin. Print it out and bring it in. Took 45 minutes. They did it while I waited. Noise goes away in about 600 miles.
