I just had the opposite experience with my local Mazda dealership. Bought my 13 CX9 about a month ago from a dealer auction in MN sight unseen with 32k miles. Had the joy of feeling just a hint of a chassis shudder when turning from a stop. (Most passengers wouldnt even notice it when i pointed it out) Being around cars for years, made me instantly worry about the transfer case.
Made an appointment at my local dealer, discusses the issues with the service writer there. He said that he has seen a few of these that needed new transfer cases. They kept the truck for the day, and only noticed the issue once out of a few drives. But since they know it can be an issue, they ordered up a brand new transfer case, and even paid extra for faster shipping. I picked up my CX9 the next day without spending a cent. Hell, i havent even made a car payment on it yet. lol
